Thin horizontal lines across TV screen - Sony KDL42W706B.


Standard Member
Hi folks,

I need your help. This weekend my Sony KDL42W706B television developed a fault which is driving me insane. Basically it was working perfectly fine and then suddenly thin black horizontal lines appeared from the bottom of the screen to mid way up. The lines are perfectly spaced and I have taken some pictures but they can be difficult to spot from the pictures. Having done a fair amount of research it appears not to be an issue with the main board but possibly a problem with the gate drivers on the panel. Now I'm no expert so if anyone else as any other idea I welcome it gladly. I can't exactly afford a TV at the moment so would love to be able to fix the issue. Already removed the back panel, checked cables (disconnected/reconnected etc) but no success. So I need some help from much more knowledgeable folks than I.

If anyone as any advice or can help me fix the issue in anyway, I would be very grateful.
