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: [url]https://techhometravel.com/samsung-un55h8000af-no-backlight-no-video/[/url]
[LIST][*]Unplugging the main board cable at the power supply >>> backlights came on.
[*]BLU_ON...
