Horizontal lines & Flickering


Novice Member
I have the Sony KDL-32WD752. It started flickering and giving me horizontal lines last night. I have got the back off and after some research thought it might be the tcon board. Upon opening looked at it and the ribbons connecting to the tcon board have these lines on? Is this normal? I build computers and never seen these on ribbons before.

Are they most likely causing the issue and if so where can I get new ones from?

Hard to tell but from the photo they just look like alignment marks drawn on with a pen rather than charring of the insulation. They're a very consistent width and stop abruptly.

Any updates on this? My TV has horizontal lines all over the screen and the backlight seems to dim for a frame every 2 seconds or so.

Edit: turning off all the picture processing options seems to have helped. The backlight seems normal now and the lines are barely visible even if I put my face right up to the screen. Hope this helps someone.

edit2: nevermind the problem is intermittent
