Left half of screen is distorted with three bands
A Sony KDL50W800C started displaying a distorted image on 3 distinct vertical bands on just the left half of the screen. Initially 10 April they were minor but have gradually become much worse with lots of psychedelic colors. I will attach some photos. I did the self check diagnostics page but the only error was back in 2021. Changing to wide screen doesn't change the bands. I have tried a replacement T-CON board but this resulted with a complete white screen and the TV was inoperable.
Left T-con board ribbon cable disconnected (looking from the back).
Right T-con board ribbon cable disconnected (looking from the back).
Back of the panel with boards removed. How to get access to the LCD driver boards?
Esta é uma boa pergunta?
