              Go with the correct LEDs to begin with. If you have 6V LEDs on the strip, replace them with 6V units. Double check the LED pad to make sure they match what you are trying to fix. eBay has 100 for $13... https://www.ebay.com/itm/223494097714

              I recently purchased these LEDs - they work well and made it my second garage TV. I replaced all 50 LEDs off of an Insignia TV.

                  RCA RLDED 4331B: 43 inch LED TV: Backlight issue
                  by lmcancu
                  Hi I am having an issue with the LED backlight of this TV. I can see the picture with a flash light, so I determined it was a backlight issue.

                  Initially, after opening it I found 2 shorted and 1 open LED on 2 strips (total of 4). I removed the LEDs and shorted the pads together to verify if the backlight would work.

                  Testing it, I found the backlight turned on and I measured 54V when TV was in standby (off), and 100v when TV was turned on. The 4 strips each contain 9 LEDs, so 36 in all minus 3.

                  Instead of putting it back together I decided to replace...

                  About replacing individual LEDS on BL strips
                  by edugimeno
                  Hi There!
                  Having fixed 5-6 TV sets by replacing full LED strips, and having watched other people fix that by replacing just one LED in the strip, my question now is what should I consider before doing so.

                  At this time I have some old strips removed from TV's with all but one LED working. Are there different voltage/current LED on different strips? Are 99% of them just the same and interchangeable?

                  How do you find which specific model is needed for each strip? When I check if a LED is OK by attaching the multimeter leads to the individual led pads on the strips I...

                  This happened last Saturday and today I finally had time this morning before I went to work to replace two non brand capacitors

                  I will let you be the judge weather or not these are bad or not according to the blue ESR meter that I am using

                  I am comparing them to a brand new one that I installed

                  The display came back on and the programming was not lost which I was surprised by I would have thought that when the display went blank that so did the memory as well

                  I going to let it run for several days before I remount back on the wall next to the...

                  LED problem on samsung UE55F6475, 2 strips work. The rest is flashing every second.
                  by Kingfreddie
                  Ok.. this is the story:
                  Have an old Samsung LED 3D TV (UE55F6475). First it started to lose light on the lower 40% of the screen now and then. Like for 10-60 mins and then it would work again. Then a bit later it just got stuck in that position. The lower 40% of the screen is dark, and it gets progressively darker the lower u go so it's obviously that LED strips where not working. I also looked for similar errors online and saw an exact copy and on that one it was faulty LED strips.

                  This is kinda how it looked, just that mine were at the bottom of the screen:

                  Soooo, I found someone giving away their 70" Vizio TV because it wouldn't turn on. Hoping it would be just some bad caps, I snapped it up. No dice. No bulging caps. TV would start consuming about 7W immediately after plugging it in, but no response from the remote or power button. Thermal showed the main chip on the mobo getting warm and nothing else. Power supply appeared to deliver stable 12V to the mainboard.

                  I ordered a replacement mobo(actually both mobo and PSU just to be sure) and popped it in. Picture! Sound! Endorphins! Then I noticed three long dark strips. Hmmm, had...
