I have an 42" Panasonic Plasma TH-42PX75U. As of recently, every once in a while, the screen goes completely blue. The same color blue as in the menus. The audio remains normal and even if you change the channel the picture remains blue. It only lasts for about 5 seconds and the picture goes back to normal. It's not that annoying as it only happens maybe once a day, but any ideas if this is indicating a future problem?

It only does it when it is hooked up to analog cable and you are using the TV's tuner. It also only happens immediately after changing a channel. I think it has something to do with the software of the TV. I have an older Panasonic Plasma at home which will sometimes lock up or display a lime green screen when rapidly changing channels. We now use a digital cable box and have not had any problems. I think it is just the TV getting confused. I installed a driver update relating to the tuner from Panasonic's website and have not had a problem since.
Several digital channels disappeared from menu. Some, including 4 pbs channels remain.
