Re: Sony KDL-40S4100 image problem vertical lines

When you say panel fault do you mean the driver board or the actual LCD panel? Why would a bad panel affect 3 segments simultaneously and the picture still show correctly every once in a while (as shown in the last image I uploaded)? Is there anything I can measure on the driver board to see if there could be a problem there (voltages, resistors etc.)? Trying to learn a bit more about this issue before giving up on this set.

My Sony KDL-40S4100 recently started having image problems. 3/4 of the left side of the screen is affected by this (see images). When I first turn on the TV the whole area is black. When playing a video it changes in color according to what is playing and sometimes the image corrects itself for a second or two. It seems that this happens more consistently with bright images. Sometimes when turning the TV off and turning it back on (without unplugging) I see vertical colored lines. This happens with all input sources.

This is what I have done so far without any change to the problem:...

As many others I am trying to fix my LCD TV. I hope someone can offer some advice.
