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.

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.... -

Hi! This TV was ready for the trash so I picked it up before it was thrown away
It's pretty new, so I thought I should give it a try. I plugged it in at home and I was expecting blown backlight as most of the TV's that get to me, but in this case it showed backlight with no video at all (no logo no menu no nothing).
TV seems internally responsive, drives stdby led red when OFF, responds to remote to turn on and off, but gets no image at all
Anything common on these sets to start with?
Thanks!... -
I have an LG 34UM68 with board EAX66876002 but it has issues with not working correctly.
It powers on, backlight comes on, but there is no OSD shown, and no video shown on the screen.
I checked over the board for any obvious visual damage, and everything looked OK.
I then took a dump of the main SPI Flash chip.
I tried to take a dump from the EEPROM, but it would sometimes read data correctly, and other times would had obvious reading problems.
I managed to get a dump from it which somewhat resembled correct data - part of the...
