Verticle lines for picture

I have a sony bravia 32'' flat screen tv that has sound, but the picture is only a bunch of colorful verticle lines. Circuit City is out of business, but I bought the extended warranty. I don't know what to do or where to turn now.

You need to describe these lines better. Are they moving or stationary? Are they very fine lines with sharp edges or are they more like bands with soft edges? How many lines do you see, and how wide are they (compared to the screen width)?

Fine lines that are stationary: defect in the electronics causing a vertical row of pixels to be dead or stuck. Can only be fixed by replacing major parts.

Broad lines with soft edges that move: could be electrical "hum" interference. Make sure you are using a grounded (3-pin) power plug, and that the outlet is properly wired. (Take the TV to a another location and see if the problem goes away).

Make sure you don't have fluorescent light fixtures nearby--they can interfere with the picture if the bulbs or ballast is defective. Could mean tecon board or display is bad which means replacing both in a sony if they are bad i recomend buying a new tv because it is not cost effective to replace these.

Hi,
I'm sorry, it sounds problem with lcd panel (screen) that is defective and causing lower half distorted image. If tv is under warranty then call number written on warranty documents for warranty cover or lcd panel (screen) replacement would cost you approx 80% of new tv price.
Hope these info will help you.

Unscrew the cable off the cable box on the out to TV end, then screw it back on. You may also try a different type of cable, like HDMI or component cable.

I have a sony bravia xbr 32 inch and the picture is only on half the screen


It is possible that Twin Picture function is enabled, turn it off with remote/ menu options.
If this is not the case then T-Con board sounds bad and needs to be tested/ replaced.
Qualified tv tech will test and replace it.
Thanks.
