Purchased in 2009 I bought it from the previous owner so don't knoe how long it has had this problem

OK, there are two possible things that can cause such issue in this TV, either t-con board is defective/ ribbon cables contacts are dirty that are coming from LCD panel into t-con board OR LCD panel is failing internally.Unplug ribbon cables from t-con board to clean their contacts, replug them and check if it helps to resolve the problem, if problem still persist then need to swap t-con board (must be same version/identical t-con board) to see if it fix the issue or LCD panel is defective and panel replacement wouldn't be possible due to high cost if it is still available with Sony Parts in area and at this point you would be better off with a new TV.I trust my input will help you out. Please feel free to respond if you have any additional questions.A positive rating to answer would be greatly appreciated, please click on smiley face/star on this page then click submit/finish button so I can get credit on website for my work.

To access t con board do I have to take the back off the TV ?

Expert:  Shahid replied 2 years ago.
Yes, back cover of TV will be removed then check top or bottom center of rear of screen for t-con board under metal shield, remove that shield to access to connectors where ribbon cables are plugged coming from lCD panel, please take care while handling those ribbon cables as they are very fragile and any damage to cables will be irrevocable and entire screen will be replaced.
