Alright. I just ordered a new TCon & Mainboard and keep you updated, if one of these will be able to bring it back to life.Leave a comment:

Of which board do you Need more pictures?
I'm not quite sure whether I get your other instructions right. So I'm supposed to disconnect the cable between Mainboard & PSU. If I do so, the backlight stays off for whatever reason. Additionally, the LVDS or the power cable between Mainboard & TCon needs to be unplugged?
And after unplugging the cables, the TV needs to be plugged in and is supposed to show the colored pictures?...Leave a comment:

There was no cleaning recently and no Otter water damage. I already checked the resistors on the LCD Board for shortages.
Taping the Board didnt seem to have an effect either.
So it's not the panel but TCon or Mainboard?Leave a comment:

LG 49UF6409 No Picture, Backlight & Sound working
Hello everyone,
so my TV recently decided to stop working.
At first, it sometimes showed just one color on screen after switching it on, but as far I remeber the menu still worked.
Now theres no way to get it to that anymore, just a blank screen :/
I've already tested unplugging either the right or left cable from the TCon to the panel, but neither halves of the TV had a picture (see attached files). The white half is always on the unplugged side, the other side stays blank.
With the right cable unplugged, the right side faded to grey after leaving...
