SONY forum: http://www.agoraquest.com/index.php Exerted:

Sony will be announcing the availability of limited TCON replacement boards to service LCD panels beginning

with certain models going back to 2006. For many years technicians have been asking about the availability

of these components. In the relatively small percentage of units that experienced a failure of the TCON board,

replacement of the entire LCD panel was mandatory. This is not only costly from a warranty standpoint but it also

makes it near impossible to justify an out-of-warranty repair since the replacement LCD panel can easily cost 2/3
or more of the price of the entire television.

My Sony TV KDL-46XBR8 begun showing lines in the middle of the screen about a week ago and now is showing a transparent block at each top corner. The TV is only two years old. Do you have any solutions for this issue?


More likely to be the T-CON board.
Does it look like this in my albums?

Bad T-CON, or bad power supply can be the cause of the problem.

Did you ever get your Sony Bravia fixed? Mine was one month out of warranty when I started getting the lines and distortion. Paid 1500 for it new and they say the part to fix is 1600 but Best Buy haven't come out and looked at it yet. Sounds like Sony needs to recall the tvs.


Sony model number?
Vertical lines, please read here about bad T-CON/LCD panel. I owuld suspect the T-CON board or bad connections on the ribbon cable between the T-CON and the LCD panel.
