Recently noticed that there is a light ultramarine-colored blob in the middle of the 42-inch Panasonic plasma screen when there's a light background (think snowy mountain or beach scenes). If you look carefully, it always seems to be there but gets hidden or camouflaged by other colors on the screen. We bought the TV in 2007 and never had any issues. Panasonic says to call in a service company ($$$) to look at it and give an estimate.
Wondering if it is worth repairing or just bite the bullet and buy a new TV?
