SONY KDL46Z4100 Dim image

[ishler]

The display on this TV looks like it's suffering from either low back light or brightness. With both controls set to max the image is dark and biased to the red. I've read the several threads on this model and although i initially suspected the backlight I can't rule out the T-con but I'm not seeing any of the artifacts shown in the photos other than the dark image. Since the backlight is integrated in the panel i was thinking of replacing the backlight driver board. I also have the equipment to change out the AS15 on the T-con if needed but thought I would ask if there were any other ideas before I start down that road?
Thanks in advance for any help

On my list of todo's. I need some help to take it down stairs into my shop. Hopefully in a day or two. Getting old is a PITA!

Can you take some pictures of screen?

Here is a picture, I wish it was more representative of what I'm seeing. The actual picture is darker with a dark shading around the borders. The backlight,brightness and picture controls are at maximum. When you back off the controls the image is redder.
