It sounds like the backlight is going bad or possibly the panel. Let me see a picture of it. Talk to you later. Jay
SOURCE: Our Sony Bravia tv picture keeps going light dark
I have Sony KDL-32XBR9 and I have noticed a similar problem. When the picture is showing mostly black, for example during the ending credits of a movie, the TV will further darken the display. Once the picture lightens back up, the TV will adjust the brightness of the display back to normal. I just called Sony customer support and they indicated it was a firmware problem and they will be sending a USB device in the mail to update the firmware. Hope this helps.

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...

Your inverter or cfl bulb is out on the right side.
SOURCE: 52" Sony Bravia TV has a thin Blue line down left
A line on an LCD screen can be cause by the screen itself going bad or the T-con board. The T-con board the attached to the screen on the backside and covered by a heatshield. If you get teh part number from it you can find it online from one of the many retails that might have it. Like www.interliquidparts.com
Hi
It could be a power supply problem or an inverter board problem or something internal having to do with the backlighting of the unit. remove the inverter, and look at the back side and you will see a hot spot, now on the other side of that hot spot, re-solder the service mounted components and that should take care of your problem.
Please get back to us if you have further query else please accept the suggestion.
