    If you replace the led strip remember to turn down the backlight since the leds are often overdriven at 100% which drastically reduces their life span.

      Re: LG 42LN5100 no backlights

      What i m in the process of doing is every tv whose panel i open up to work on i take notes of the LED strips (Stripe model number) and LED size and bias voltage. I also write down the bias voltage for entire LED string. Then if i pick up a problem i already know what the led bias voltage should be without having to open up the panel to find shorted LED's> This saves time on the long run. Also when quoting on a tv whose backlights are faulty i don't have to open up to get an idea of the led strip type. I can quote directly.

        That could be a useful sticky.

          Corsair K70 LUX RGB dying LEDs
          by Pipolups
          Hi there !

          I'm having an issue for several weeks with my quite old K70 LUX RGB keyboard. I haven't used it for few months, and once I setup up again my desktop computer, I got several dead LEDs on that keyboard. I tried the Corsair troubleshooting thing (disabling options in iCUE, ...) but nothing changed so I conclude that for some reason some LEDs went in retirement...😅
          Decision taken to change these LEDs as I have access to desoldering iron and binocular magnifier, I wrote a ticket to tech support, hopping to obtain the LEDs reference and... They refused to tell me 🙄...

          Samsung UE48H6410 replaced Mainboard but backlights doesnt go on
          by max789
          Hello, I have a problem with my Samsung UE48H6410SSXZG with the main board BN41-02156A and the power board BN44-00709A. Everything seemed like this, the TV could no longer be switched on, the standby LED always flashed 5x2 times. Backlight was off and no sound from TV. Also made the flashlight test and there was no picture.

          I made the following tests:
          1. Disconnected the main board from Power Board = backlight works.
          2. Connected the main board and disconnected the T-Con = backlights does not work.

          So I ordered a main board from Ebay also BN41-02156A but from...

          VIZIO M557-G0: Backlights or ???
          by bpcannan
          'Morning,
          I get sound and picture when powering on the TV and its stays that EXCEPT that the left half of the screen will dim every few seconds then return to normal while the right side of the screen performs as designed.

          Did the soft and hard reset options pulling the plug, using the reet option in the vizio menu to no avail.

          I checked the mainboard - found some popped capacitors so replaced it - but that did not change the situation.

          I checked the t-con board. It is getting good power. Then I removed one ribbon cable to see if I could isolate...

          Insignia NS-37D20SNA14 intermittent LEDs
          by THE GTC
          So I use this TV daily as a second monitor for my PC or my Playstation - at one point a few months back I tried to fix the problem - but in the process, I figured out something that works so I haven't posted this for awhile. It is an annoying trick to have to do though, so I decided to post about it to see if anyone could spot what's wrong. It baffles me because it works on it's own half the time.

          When I first got this TV, I was told it wouldn't turn on, and of course I did the flashlight test, and the image was there. Also, the red LED on the front indicated that it had power (it...

          A2338 Screen replacement - Clarification needed. What do you actually loose when replacing the screen with OEM Pulls?
          by AJ847.63e
          Hi All,

          Just wanted to get some clarification on replacing screens on M series machines (M1,M2,M3,M1pro,M2pro,M3pro) as there is so much conflicting information out there. Some say even when using OEM pulls you lose True Tone and only that, others say you lose that and webcam, others say you lose those two and also the lid sensor will not work, others say you lose nothing as long as you use OEM pulls.
          So, which one is it actually? Using original OEM pulls. That seems to be what has caused the confusion, people using cheap aftermarket than being surprised when it does not work...
