How to fix sony lcd negative image issue - Televison & Video

T'Con board fault. In some models of LCD TVS; the backlight inverter and its T'Con board will be a part of the panel itself, and will be a built-in type inside the LCD panel.If so, they can't be replaced.In this case; a panel replacement is the only repair.For some other models, the backlight inverter section circuit will be a part of the main power supply regulator [SMPS].To such sets, the power supply section circuit too should be troubles hooted.Contact any service technician.The circuit will differ with models and versions.

If your LCD TV or monitor has stopped working, or is displaying one of the following symptoms, then it's a candidate for some new capacitors
- Flickering screen
- Screen image disappears after several seconds
- Dim screen
- Slow start
- Power LED on, but no picture
- Unusual colors and/or lines
The primary cause of LCD TV and monitor failure is caused by faulty capacitors. You can examine the capacitors in your LCD TV or monitor and actually see if they are bad.
If they appear bulged on top, then they need to be replaced.
New capacitors will solve a host of problems in LCD monitors and TV's and will extend the life of your monitor or TV by several years.
Take it to a repair shop.

Its a TAB bond Problem with the LCD. You can take apart the TV and install a rubber Bumper to put pressure on the TAB. TAB bonds always get worse... I dont know how long it will solve the issue... but u can get a little more life out of it.
Rember when working with the TV the voltages can kill!!
Heres a link to see someone fixing.
I have the same TV...same problem...common problem...unless u ask Sony.

Hi,
Its back light in LCD Panel problem, there are approx 20 CCFLs in 40" lcd panel and one or two in upper half is not providing enough light to give proper brightness so you see bit darker image.
As per Sony policy, lcd panel will be replaced to fix this issue and local tech can fix it on component level (replacing bad ccfl) if he/she agrees because its risky work.
Hope this nfo will help you.

Sony had a certain issue with the CCD chip on this camera. If it's this issue, they'll fix it free plus $20 until March 2010.

That is an effect that can be had by internal software in the camera, like my Sony. Just get in there and turn off "negative" Youll probably see Sepia, solarize, B/W and negative as other choices.
