I have a white splotch on my panasonic rptv. It is about 2 inches by 4 inches with irregular edges, and is centred on the screen about one-third of the way from the top of the screen. Initially, I thought it was a reflection on the screen, as I first noticed it only during daylight hours with light streaming through the windows in front of the TV. And I only saw it with the tv turned off. However, I also noticed this same splotch when I had a solid blue background on the rptv as I called up my processors osd for adjustment/calibration. The splotch is not visible while watching cable/dvd sources. It has become irksome, though, as it is visible with the TV turned off under most lighting conditions except extreme darkness. Does anyone know what could cause this? (My tv is a 47" Panasonic cinevision-1 year old). Thanks.
