sony kdl 32xbr9 TV

[willy3486]

I am looking at a sony kdl 32xbr9 TV for a friends elderly parents. It has a issue with the screen regardless of input. What is going on is the screen in the middle to about 3/4 of the way to the right hand side is dimmer. The first half of the screen is fine and the last 1/4 is fine as well. There is a strip from top to bottom that does have a picture but is just dim. I am trying to do the update but I need to find a usb that will actually work with this model. I am more familiar with TV tech of the 70s and before and not so much on the new stuff. Has anyone seen this issue and I was wondering if it was caps, a board, the LCD itself or even if it is worth fixing. Any sugestions?
