    Ecco LH32, No backlights

    Hi everyone
    I have an Ecco LH32 Led tv with no backlights. PSU is reading 7.6 v, using two led strips of 6 leds each, I have no backlights tester.
    Does anyone know the backlights voltage for this model. Also want to ask if backlights leds come in a parallel arrangement, or series only
    Pliz help

    Each led is about 3v. Each strip is in series.
    I assume no responsibility for any stupid suggestions I might post.

      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...

      Samsung UE49MU6400 acts dead until disconnecting backlights, then works.
      by jesterace
      Hi everyone I have this TV which was dead one day when I tried to turn it on. I've had the cover off and there was just a pulsating/electrical clicking/ticking noise from the PSU. I disconnected the mainboard as sometimes this works to just fire it up with backlights on? That didn't help. Same noise. Then I disconnected the backlight cable from the PSU and the TV came alive. It appeared to respond to the remote and i'm pretty sure it's fully operational when there is no backlight connected.

      However, I am in a dilemma.

      I tested the backlight outputs with the lights disconnected...

      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...
