Re: LG 86ul3e-t logo blinks and then nothing (but backlight stays on)
In post #11, on the picture driver_3_1.jpg are the two ribbons that goes to the TCON. But each pair of the driver boards is connected with the mentioned "U-ribbon". You can see the connector on the pictures "driver_3_4" and "driver _4_1".
@budwich: Thanks for the hint, I will try that. I afraid, that the broken driver is the third board, so if it is a first in line, from the TCON, than it will not start until I find the fail. I thought that with two sides of the panel, when I disconnect the half, I will get a part of the screen on. But only when all four ribbons are conencted, the logo apears. Probably the whole panel must be operational to get the proper picture on the display
