Bravia KDL-46w4500 LCD tv vertical and horizontal lines, sound OK

Hi all,

My TV has vertical AND horizontal lines. The horizontal ones are flickering.

I did read disassemble the TV and patted all the LCD connectors - no help. They all seem to be pretty tight.

Don’t want to order the new T-con board if the issue may be different… Could you help?

The sound is OK, the OSD volume seems to be on top of the flickering lines (with the lines showing through). The yellow menu icon frames seem to be solid (with lines not showing through), but the light-grey icons themselves are transparent and the lines seem to be under those.

Thanks!!

Soluzione Prescelta

@andriyc

those lines do not look like anything from teh T-con board due to the transparency. There is always a chance that all of this is caused by bad panel drivers which is not DIY fix. I’d go with a new main board to see if it will make a difference. The T-con board failure would usually produces solid (non-transparent) lines.

Thanks so much! You seem to confirm my doubts about the T-con board solution. Is there a way to test my current main board for these issues? I would hate to buy a new main board just to learn it's not the solution, either. Although if there is an over 80% chance that it's the main board - I will get one. Thanks!

@andriyc I'll check to see if I have any info on your main board.
