    B140XW01 V.0 Bad Tcon (White Screen)

    Hi, I have this LCD Panel. I know it's a cheap panel that I can easily replace but I'm trying to repair it.

    Is giving a white screen. I already checked with the oscilloscope that I have EDID Data and CLK. But besides that, I'm clueless. Don't know what to measure.

    Backlight works all right, and VDD is 3.3v stable.

        You can flash the EDID,it could be corrupt,but how are you going to test for an image on the screen unless you hook it up to the laptop ? or a controller board like this - https://www.ebay.com/itm/DVI-VGA-Aud...-/172319454906
