    Video: Repairing backlight at a Philips TV 43PFS5301

    Hi,

    I had a Philips LED TV with sound but no image. The video gives you a tutorial how to repair the backlight.

    The video has a German soundtrack but English subtitles are added to YouTube.

    Enjoy it,

    Jürgen

      Samsung UN55H8000 sound but no backlight no video
      by Max514
      Hi all,

      Ok so I have this beautiful un55h8000 samsung tv with sound but no video nor backlight. When turning the set on the red light blinks 5 times.

      The screen shows no damage and backlight turns on when I disconnect the power supply from the main board. The tcon board only has 2 out of 3 leds on.

      I came across this page and followed the different steps: https://techhometravel.com/samsung-u...ight-no-video/
      • Unplugging the main board cable at the power supply >>> backlights came on.
      • BLU_ON signal from the

      Philips TV Backlight Repair
      by chestercc
      So i'm trying to replace the LED's in a Philips TV. It's 42" with a 715g7262-p01-000-0010 backlight driver board based around an O2 Micro OZ9902CGN.

      My issue is when I replace all the LED's on one board with the new 3V 300ma ones they immediately burn out when the set is powered again. I previously tried the same thing with 6V LED's and the backlight flickered for a bit but wouldn't start.

      The original LED's which I removed which are still working start to melt and burn when given more than 3V on DCPS so I know they shouldn't be higher voltage ones.

      Trying to control Philips backlight manually with PWM — brightness increases with frequency...?
      by ohren
      I raised the question of whether PWM on the power board "dim" pin would be a reasonable assumption for controlling the backlight of a Philips TV (55put6101/12): https://www.badcaps.net/forum/troubl...d-tv-backlight. I didn't receive any insights there so I went ahead and tried it.

      The setup is basically:

      Rpi3 hardware PWM → 220 Ohm → NPN transistor → dim pin

      Transistor is switching the 3.5 V supply on the power board....

      Vizio D32f-E1 Powers on, has backlight, won't boot/no logo, no menu or video
      by JaquesPratt
      I have a Vizio D32f-E1 LCD TV that does NOT have a TCON board.

      This TV recently went through some 'death throes' and now won't boot. The first problem that began to manifest was while watching tv, the screen would 'freeze', and the image would dim over a few seconds until it was very dark. HOWEVER, the audio of the show would continue as normal. I could power off the TV for 5-20 seconds, power back on, and the video would be normal. This would occur 1-3 times when the TV was first started, and would not happen again after the TV was 'warmed up'. Not ideal, but this glitch was manageable....

      Philips 75PFL5704/F7 A Video Issue
      by Nicktronic
      Hey everybody, got a strange one here.

      The TV will display the Home Screen, Menus, Netflix Home Screen, YouTube home screen with preview tiles, etc, without issue. As soon as I try to play video (streaming or from any of the HDMI inputs), all I get is audio and and blank screen. It's like the video is not being processed. So I ordered a replacement main board. I can now play video from streaming sources but the video from HDMI sources is all green (kinda like photo negatives but all green) and the audio does not work. Is it possible the main board I ordered is also failing?? I can't...
