I have the same problem with the orange and green lights blinking after replacing the tcon board. Any suggestions
ReplyDeleteAs all of you I have the same problem, but the center of my picture is darker than the rest of the screen, and of course the different colored vertical lines that come and go according to the brightness of the image,, it seems to me like some type of automatic gain control that is not responding properly, but the million dollar question is,,,does SONY know exactly that in fact it is the T-CON board ? or they just want to do the replacement thing that makes you think if it's worth it? or just buy another brand? Speak up SONY!!!!!!!! there's too many people with the same problem.

ReplyDeleteHello dear, i have aome problme with my tv, technicians asked me 250Euros whithout service. I want to try to repair myself.
ReplyDeleteThe problem is that the tv switch on and it presents soem lines (horizontal) on bot top and bottom of screen .. very tiny lines BUT after 2 minutes the screen become black, i can hear audio but nothing else. Do you think it is the TCON board ? What do you suggest to do ? I would like to be as sure as possible it has the problem before buying a new one and discover that the problem is the same .
