SOURCE: 12 little horizontal lines in Sony Bravia KDL-52W4100

we have the same exact tv and it is not even a year old. we are told that it is the display panel and it is a well known problem with this tv. we were also told that there is a shortage of these parts. they had 283 on order, but only received 35. you need to call sony and tell them that you have this problem. they should warranty this for you even if your tv is 3 months past the warranty period. since this is a well known problem with this tv, keep on them.

SOURCE: sony bravia kdl 32l4000 - color bars running vertically on screen

In most cases is the screen is covered with vertical lines all the way accross the screen then the T-Con module is at fault. The t-con board is replaceable without having to replace the entire LCD panel which would usually make it cheaper than replacing the TV. The part number I come up with is 1-857-213-11. Please take a moment to rate my answer. Thanks...

Lines or doubling on one side of screen


The last Sony LCD set I had with a problem a bit like this had a bad LCD drive board. This is the board at the top of the set--that connects between the LCD panel and the main board.

Sony Bravia KDL-40S2000 thin vertical line


If the line is present in all inputs and modes, there is a problem with the LCD Panel. The only way to fix it is to replace the whole LCD Panel which is very expensive (usually around $1000+ for 40" Sony). Unless the TV in under warranty, it is usually around the same price for a new TV.

Dark area on Sony LCD screen model KDL-46XBR4


This model of SONY TV uses a Samsung display panel, the problem you have is the panel went bad.

SONY was offering an extended warranty to change the panel free, please call SONY to check it out that if they still offer the free replacement.
