I'm thinking I know the answer but I'll ask anyway. A couple of weeks ago I was watching a B&W film and noticed the bottom inch or two of my Sony KDF-55WF655 Grand Wega has a purplish tint. It's not as noticeable watching in color, but it's still there. I'm not sure how this happened. We have a PC hooked up to it and it's roughly the height of the browser footer when it's full screen, but we don't use it enough to have caused a burn in. What can cause this and is there anything I can do to repair it? Could it be as simple as replacing the bulb? The unit is six + years old and we've only had to replace the bulb once. I've noticed the picture is a tad dark and am thinking of getting a new bulb for standby. Is there some way or resetting the unit via the service menu? I'm thinking I'll need to have it serviced. Honestly, I'd prefer to get a newer TV. This one doesn't look near as good as the ones currently available. Doubt my wife will go for it, tho. It's not a big deal and I rarely notice it, but I know it's there and it bugs me.
