My samsung LN40B500 is darker on leftside. Unable to adjust

Customer Question

My samsung LN40B500 is darker on leftside. Unable to adjust it better. Adjustments appear to work. I replaced the power supply board 2 years ago. I put in a new signal board this time because I thought signal was weak. Are there any schematics available or block diagrams to help with locating problem or any suggestions. Old Electronic Tech.

EXCEPT WHEN i DO THE TEST COLOR PICTURE. IT IS OK.

Guess that would mean that the tv menu is ok

Does not make sense that you would have only one test where everything is fine

I`m going to opt out now
