Alternating Current (your house current) fluctuates or oscillates 60 times a second.. hence "60 hz". The diodes on these things are balanced with the deign load. Don't buy the one that has the most bulbs or the brightest with the most light changing modes. I replaced it with a new bulb and the whole strand worked fine. They do chew them even when they are on but I leave them on for the remote possibility I am right. Ken Wodlinger, We should not have to spend all that time to get a string of NEW Christmas lights to work.My daughter and I spent hours pulling lights ( very hard to remove) on my one year old 9 strings of lights.

This sometimes makes it hard or impossible to realize the supposed 25,000 hour lifetimes, let alone the 100,000 hours they were touting when these first started coming out about 10 years ago! INSERT THE LITTLE HOSE FIRST in one end of your wire, so you don't have to splice it lengthwise again to insert the repaired/or replaced transistor. I'm leaning to the latter. Consider purchasing energy-efficient LED (light-emitting diode) lights. 3. Christmas lights have a small fuse box close to the plug end and are usually one in the same thing. You could in fact lose up to 25 lamps from these strings (every other lamp) and they'd continue lighting! The string I took apart had failed and the cause was dry solder joints at the diodes. My two light sets had the same issue - half of each not working. There is also no in-line box or anything indicative of additional in-line electronics. I inspected the wire for breaks. Typically on LEDs the longer lead is anode. This is not unusual in itself- many types of Christmas light strings have rectifier diodes to reduce flicker, and they're used in some LED rope lights as well. They are the 70 set LED strings. The load per light bulb never changes as the resistance stays the same and the voltage stays the same so the amperage per light bulb won't change. « BACK TO Artificial Christmas Trees; Easy Setup; Flip Tree™ Stored upside-down on built-in rolling stand and flips into display position. You could check with a voltmeter to see if you are getting 120vAC out of the socket on the tail end, which if zero would mean a wiring break. The prongs from the extension cord do not fit into the end of the LED string. wikiHow's Content Management Team carefully monitors the work from our editorial staff to ensure that each article is backed by trusted research and meets our high quality standards. wire to complete the circuit so try to find the proper diameter extension wire or place a few wavy bends in it to insure contact. AS you might have noticed in the submissions to this post, many strings have two or three sub-sets in them. I knew I wasn’t going to get every light working on … My understanding is that Christmas light strings like these are often two independent circuits, with fuses built into the plugs at either end. This will be costly on a bulb-by-bulb basis, but should solve a basic problem that is driving us all crazy. You can remove any bulb in the darkened section, or even a lit bulb that’s near the darkened section. I fixed mine by taking a copper wire about 1.5 cm (5/8") long and inserting it into the hole alongside the broken terminal wire.

Even the Firemen at Vancouver's Stanley Park's 'Christmas Bright Nights' display can't get these LED strings working, and THEIR 'on the clock' getting PAID to try to figure them out ! Alternating Current (your house current) fluctuates or oscillates 60 times a second.. hence "60 hz". The diodes on these things are balanced with the deign load. Don't buy the one that has the most bulbs or the brightest with the most light changing modes. I replaced it with a new bulb and the whole strand worked fine. They do chew them even when they are on but I leave them on for the remote possibility I am right. Ken Wodlinger, We should not have to spend all that time to get a string of NEW Christmas lights to work.My daughter and I spent hours pulling lights ( very hard to remove) on my one year old 9 strings of lights. Best advise I got from this web page was go buy another string and keep these bulbs for spares. I have the same problem and i tried to fix it, my Christmas lights are 120v and 60Hz AC. That website/blog has all the possible variations of everything that can possibly happen with these lights and how to actually fix them. it was easy to replace the bulb every string comes with replacements. This sometimes makes it hard or impossible to realize the supposed 25,000 hour lifetimes, let alone the 100,000 hours they were touting when these first started coming out about 10 years ago! INSERT THE LITTLE HOSE FIRST in one end of your wire, so you don't have to splice it lengthwise again to insert the repaired/or replaced transistor. I'm leaning to the latter. Consider purchasing energy-efficient LED (light-emitting diode) lights. 3. Christmas lights have a small fuse box close to the plug end and are usually one in the same thing. You could in fact lose up to 25 lamps from these strings (every other lamp) and they'd continue lighting! The string I took apart had failed and the cause was dry solder joints at the diodes. My two light sets had the same issue - half of each not working. There is also no in-line box or anything indicative of additional in-line electronics. I inspected the wire for breaks. Typically on LEDs the longer lead is anode. This is not unusual in itself- many types of Christmas light strings have rectifier diodes to reduce flicker, and they're used in some LED rope lights as well. They are the 70 set LED strings. The load per light bulb never changes as the resistance stays the same and the voltage stays the same so the amperage per light bulb won't change. « BACK TO Artificial Christmas Trees; Easy Setup; Flip Tree™ Stored upside-down on built-in rolling stand and flips into display position. You could check with a voltmeter to see if you are getting 120vAC out of the socket on the tail end, which if zero would mean a wiring break. The prongs from the extension cord do not fit into the end of the LED string. wikiHow's Content Management Team carefully monitors the work from our editorial staff to ensure that each article is backed by trusted research and meets our high quality standards. wire to complete the circuit so try to find the proper diameter extension wire or place a few wavy bends in it to insure contact. AS you might have noticed in the submissions to this post, many strings have two or three sub-sets in them. I knew I wasn’t going to get every light working on … My understanding is that Christmas light strings like these are often two independent circuits, with fuses built into the plugs at either end. This will be costly on a bulb-by-bulb basis, but should solve a basic problem that is driving us all crazy. You can remove any bulb in the darkened section, or even a lit bulb that’s near the darkened section. I fixed mine by taking a copper wire about 1.5 cm (5/8") long and inserting it into the hole alongside the broken terminal wire. A friend of mine just put up all his led strands and low and behold there are at least 3 or 4 sets out of 15 that are completely dead. I bought a two-prong outdoor extension cord to run between the shrubs. Works great. I had the same problem with three different sections of my LED lights. LED's are good for sub zero temperatures, so any fault must be in the string. While your instinct may be to just toss the whole string and buy a replacement, there are some simple measures you can take to possibly repair the string. Please inform me by step by step on how i should fix my lights. I looked at the strand and actually pulled an LED out, and there is in fact, no diode. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws.

The good ones will have a distinctly lower forward (pos on anode, neg on cathode) reading. Check the entire strand of lights for a missing, damaged, or abnormal looking bulb, according to the Christmas Light Company website. The last 2 lights on the dangle seemed more corroded than any others. This image may not be used by other entities without the express written consent of wikiHow, Inc.

Although the string and most of the lights will last forever, the failure of a small component renders the entire string (or large sections of strings) to the garbage. I repeated the test to see if I got the same result and that is what happened. Pre-Fluffed™ Light connections inside the trunk, and memory wire branches reduce fluffing. It might be best to get rid of those offending string(s), or give them to someone who knows what they are and how to properly use them. Some bulb seats have plastic latches that snap onto the socket exterior. After identifying the problem, you can try replacing any bad bulbs or fuses, or repairing a bad shunt (in incandescent bulbs only). This article has been viewed 19,626 times. % of people told us that this article helped them. Bruce Nelson. In theory, this means you can cut off the non-functioning half of the light string and splice in a new end plug or half string of lights. is it worth trying to replace the fuse? Give it a try and thanks for the Christmas Spirit....Good luck. There are paper that both say connector so you put them together, then there are two more male and female parts and you put them together & the bottom 1/3 of the tree lit up. If you try to cut out the fusible links or even replace them with a more serviceable unit, you need to understand something about LED's as opposed to incandescent lights. Start with the first unlit bulb and work your way down, wiggling them to check for looseness. The various ‘forums’ offer different methods to solve this problem, but most don’t work . If you doubt your abilities or the situation, it would be far better to just buy a new string than possibly risk your life! 1) These starnds are actually split up into 3 sections and a bulb going out will kill that section of the strand. It will start working again and turn on the rest of the strand with it. Don't hold your breath waiting for that. A. So don't go thinking these strings would be good with your light show controller if it does any dimming at all. wire. Ok, so I am having the same problem. Go figure. Before you panic, we have good news. I know in regular incandescent christmas light sets, that if too many of the bulbs go out, then the entire set starts to fail quickly. To achieve standardization, the LEDs for these, both red/orange/yellow and green/blue/white alike all have a forward voltage of about 3 volts and are thus interchangeable!!! Just like finding an LED that is open except not looking for the LED's to turn on, but will increase slightly in brightness. Every day at wikiHow, we work hard to give you access to instructions and information that will help you live a better life, whether it's keeping you safer, healthier, or improving your well-being. Seems like there are lot more problems to LED lights which requires more thinking process. I hope this all is not too confusing and offers some help before this holiday season!

\u00a9 2021 wikiHow, Inc. All rights reserved. 11/24/2017 by You may find a wire just the right diameter to touch the shortened l.e.d. With the lights plugged in, use the voltage detector to check the live voltage wire between each light, starting at the end that plugs into the wall outlet. The problem is when i brought m lights out and plugged them in, for some reason the whole entire light string wasn't working. If not I just replaced it with a good one. All bulbs now burn. I hope this answer is helpful to someone. I suspect up here in the frozen north, that we don't have replaceable bulbs and fuses like I see in this discussion. Keeping them upright is really impossible. The soldering was typical awful Chinese soldering using lead free solder. Interestingly, the packs of bare replacement LEDs available on eBay, etc. With luck, your holiday decorating will brighten back up! Bill Matusevitz, i have my Christmas lights up and i went out side this Morning and it is full of water i need to stop it before the Christmas lights get Turn on. LED's operate on Direct Current (DC) and will only light with that current running in one direction. While you are inspecting your defunct string, break into and have a look at an LED.

Now that you have exhausted your supply of working LED Christmas lights, it is time to address the malfunctioning group. If good insert in socket and then the light set. smileycyrus. Welcome to ifixit and hope to learn ore from you. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. After reading most of the Q & A's here. When only half the string lights up, it's usually because of a single light in the bad section. Why? I'm not advertising for them , but advising for us 'fed up with crap' posters . On a 200 light set, there are five parallel strings of 40 LED bulbs. Low and behold, I found 5 of the lights from the side that didn't work would not light. Fellow Canuck here. Every light removed increases the amperage of that one string. On most of my strings the covers are hard to pop off. Put them back up -- half worked. I stumbled onto that last year. Many times it still didn't work so I took out the unlit bulb, and pulled out those two little metal prongs on the side to make a better connection. They supply two light when you buy them at first. mine are working now! The fuse was there to prevent further damage (fires). I think CSA should ‘pull’ their ‘Stamp of Approval’ from ALL LED light manufacturer's in ALL countries until they can make these light strings WORK consistently, and for a long time . One way to avoid this is to get lights with covers that screw off. If you exceed the maximum connectivity for your light strand it will blow the fuse.

If a string of lights fails to work, the fuse may be bad. :(... And I must mention, unfortunately, that these strings have 2 major problems, unless they've fixed them recently: 1: they include a small circuit board in each male and female plug. Some 'progress' ! I'm working on 150 led light set right now . i have C7 diamond cut and they don't seem to have prongs. Trouble-shooting these groupings by shorting out the connectors etc is not recommended, because those bulges on the string are configured for the number of lights in the string. This makes it virtually impossible to get that one section of lights to work unless I decide to do the repair in the non-working environment . just added an image due to another question about this.... only 54 more sleeps!!!!! Okay. I can't keep the nutty looking ones going for even a couple of years. 12/07/2010 by So far I have not succeeded in repairing ones with one end or half a string out. One light has to come out because they chew so close to the base. So, I am now searching for 5 replacement LED lights to see if multiple LED failures caused the problem. Using a double feed from live and neutral powers the leds at 2x the power-line frequency or 120Hz here in North America which makes the strobing a bit less noticeable. I am not sure where you are located but I get my replacement fuses at Walmart and its a lot cheaper and less time consuming to start with that. If the individual lamps are not removable then I splice them in by stripping 1cm off each wire, twisting them end to end and soldering, and finally covering the splice with a 2.5cm piece of dual-wall adhesive-lined black heatshrink tubing to seal the connection . There is usually an indicator on the LED holder that shows a "long" side and a "short" side. You can't see this if they are stationary. RoddyMacRoddy. They also pass 120V AC to the next strand (and in my case, through 10 strands) because they power small incandescent mini light globes at the end. (not the #3 male) Any sign of heat in that end? The light guys know this. The plug at the end with the problem looks like it has a small catch you could push in with a small screwdriver, but it appears almost impossible to pry open the plug without damaging it. It seems that your entire string does not light, so I would point to the male end as the problem. These lights came from Holiday Time LED mini light set (50 COUNT) purchased from Walmart. Not knowing what a piece of crap these Can Tire Noma LEDs are, I invested in a whole bunch of strands to wrap our 3 story evergreen. Gimme' my old 2-wire 'screw-in's' ANYDAY, 1 -out, 1-in, fixed, ta-da ! Give me back the old ‘2-wire’ incandescent’s, those worked for decades , if ONE went out, you replaced that light , not the whole string ! By-passed two led strings (that were working fine) with an extension cord and the string worked fine. The toughest thing about doing this is getting the light covers off to expose the LED. Even LED strings of Christmas lights can fail if one bulb in the circuit burns out, especially if the string is wired in series, not parallel. 1). You can have 1 weak link in all the strings of Christmas lights and without a proper guide it can be very tough to diagnose the issue. wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. LED strings sold in brick-and-mortars (at least here in Tucson, Arizona) have not used mild-steel-leadframe LEDs for several years now (yay! I think water follows the wiring and eventually finds its way into these lowest sockets. If the string still won’t light fully, it’s probably time to just replace the whole thing. {"smallUrl":"https:\/\/www.wikihow.com\/images\/thumb\/2\/2b\/Fix-Christmas-Lights-That-Are-Half-Out-Step-01.jpg\/v4-460px-Fix-Christmas-Lights-That-Are-Half-Out-Step-01.jpg","bigUrl":"\/images\/thumb\/2\/2b\/Fix-Christmas-Lights-That-Are-Half-Out-Step-01.jpg\/aid11407630-v4-728px-Fix-Christmas-Lights-That-Are-Half-Out-Step-01.jpg","smallWidth":460,"smallHeight":345,"bigWidth":728,"bigHeight":546,"licensing":"

If the second string still works, then you likely have a problem with a bad bulb or fuse in the first string. (The manufacturers fudge it a bit, you see, as we've come to expect from this quality of product- sometimes 6 or 8 volts is close enough to 5 for them). Definitely have more longevity than the "nutty" looking ones BUT they are at the front of the house where maybe the squirrels are not as interested in them? The individual LEDs are designed to easily screw into conventional light sockets. Slide the cover back over the compartment, then plug in the string and see if all the lights work. Any ideas before I head out to Canadian Tire? wikiHow, Inc. is the copyright holder of this image under U.S. and international copyright laws. I'm Canadian. (B) If -all- of the lights in a chunk are OFF, its very likely that -one- of the bulbs burned out, but its shunt did not work properly. Yes, the LED Keeper can find the culprit. oldturkey03. with a power tester find the light that is dead, cut the wire on each side and marret the two ends together the string should work fine minus 1 light .i have fixed 10 failures this way. A simple solution: Inspect each l.e.d. Since Christmas is right around the corner I figured I'd chime in. The 'electronics' are housed in a heat molded lump of plastic close to each end of the string. Power is received at BOTH ends , but no lights, or only half of either end . They will disappoint. Alright, fuses are okay what's next? But ONE of the lights which wouldn't work was "so dead" that even the other lights wouldn't work. Try moving the LED's when they're on and you'll see little dashes of light. Inspecting it closer, I found it was half a string, precisely. We know ads can be annoying, but they’re what allow us to make all of wikiHow available for free. I imagine you are plugging in outdoors, so it could be the duplex (Wall plug) that is the real problem. The other thing that can happen is that you might have more than one burned out lightbulb.

When you're reinserting the bulbs, it doesn't hurt to gob a little vaseline to keep water off the steel leads which rust. Mini light testers do not work on LED trees. Accessibility. I end up with a raw thumb if I have to pop several to find the bad light. Those are the bulges on the cords, or they are built right into the male end. So fro not working i got to work but it only works have way. The 'fuse' on some lights made for the north american market is actually a low value resistor which appears to be a 1/4W size moulded along with a couple of diodes into a blob both ends of the string. They also carry a wide asst. A bad socket can cause a very dim result. It should touch the broken terminal wire to make a complete circuit so I made a few slight bends to get a sure contact. They do have a "Threshold" that once exceeded will fail, then that whole string will be out. Unplug and flip plug 180 and replug and the other half comes on -- and the half that did work now does not.

Half a strand out, flip the plug 180 degrees and the other half is out. Solid connected lights that can't be removed and the ones with two wires that can be replaced. This issue came about because around 2007~maybe 2008 one brand of string available at The Home Depot, ACE Hardware and possibly others contained a bridge rectifier (four extra, non- light emitting diodes that direct both half cycles of the AC waveform into the same direction to make the LEDs brighter and with less flicker, as mentioned previously.) If you did basic math E=IR for the circuit than what Roddy said would be true, but that is only part of it. There's .008 A on them and of course 0 on the third that comes out of the first bulb. oldturkey03. wikiHow is where trusted research and expert knowledge come together. There is a gap in the line - like someone "dropped hands" - and now the power does not flow. There should be voltage detected at the live wire going into the first light. @smileynish. @petezie. RoddyMacRoddy. If a short or a break occurs in any of the light strands, one or both of the fusible links will blow, are sealed for life, and are not serviceable. This puts this problem squarely in CSA’s ‘bailiwick’ . I piled up all my strings with 1/2 not working or half really dull. IF you suspect dampness is the problem, you can disconnect string #2 and spray a drier in there (or hydrogen peroxide), then knock that out and put some white rice in a bag enough to encase the end, tying it on tight and leave it for a day. 7. C6 bulbs are strawberry shaped.. C7 and C9 bulbs have the traditional shape you might have grown up with—larger than the strawberry-shaped C6, with the C9 the largest of all. Holly girl celebrate, half a string is better than no string, cutting the 'broken half' off makes sense - as long as the good half still works afterwards. If I haven't said it before, if you were smart enough to keep your old 'screw-in' light strings, the BEST 'commercial quality' 'heavy duty built', bulbs and strings I've found are from ; http://www.noveltylights.com , they have 'screw in' C-9 & C-7' LED bulbs. Thanks OldTurkey. Will report back if Home Depot 'Magic' Tester gun much help . you have three choices. Except I started at the plug-end and it was third from last at the opposite end. I can’t figure out where a fuse would be. So, I believe GE has a bad design here which allows water into the area of the socket which makes connection to the bulb. Put A LOT of tape (duct, electrical?) Last night I had the good ole plug them in and 2/3 of the lights do not come on AFTER testing them in the garage. I replaced the fuse in that plug (there are 4 in the wreath) and it's good as new. And i do have a multi meter with the positive and negative leads but where do i check (place them) to find out if the circuit is flowing freely. After pre-testing and hanging all 4 strings initially worked. This is a very annoying situation to be in, but I FOUND A SOLUTION! No lighting on those. This image is not<\/b> licensed under the Creative Commons license applied to text content and some other images posted to the wikiHow website. Expensive but inedible for a squirrel and replaceable.

INSERT THE LITTLE HOSE FIRST in one end of your wire, so you don't have to splice it lengthwise again to insert the repaired/or replaced transistor. I'm leaning to the latter. Consider purchasing energy-efficient LED (light-emitting diode) lights. 3. Christmas lights have a small fuse box close to the plug end and are usually one in the same thing. You could in fact lose up to 25 lamps from these strings (every other lamp) and they'd continue lighting! The string I took apart had failed and the cause was dry solder joints at the diodes. My two light sets had the same issue - half of each not working. There is also no in-line box or anything indicative of additional in-line electronics. I inspected the wire for breaks. Typically on LEDs the longer lead is anode. This is not unusual in itself- many types of Christmas light strings have rectifier diodes to reduce flicker, and they're used in some LED rope lights as well. They are the 70 set LED strings. The load per light bulb never changes as the resistance stays the same and the voltage stays the same so the amperage per light bulb won't change. « BACK TO Artificial Christmas Trees; Easy Setup; Flip Tree™ Stored upside-down on built-in rolling stand and flips into display position. You could check with a voltmeter to see if you are getting 120vAC out of the socket on the tail end, which if zero would mean a wiring break. The prongs from the extension cord do not fit into the end of the LED string. wikiHow's Content Management Team carefully monitors the work from our editorial staff to ensure that each article is backed by trusted research and meets our high quality standards. wire to complete the circuit so try to find the proper diameter extension wire or place a few wavy bends in it to insure contact.
