My 50" 7-8 year old Mitsubishi big screen has a problem with the video. It started yesterday and may be related to a power outage, as when I returned home my clocks were blinking indicating the power had gone out and the t.v. was not the same
The problem is that the only inputs I can switch between are Ant A & Ant B (I have VCR, DVD, etc. inputs). But the screen is blue for the A&B antennas, but I could hear regular sound from my DirectTv but no picture.
When I use the picture in picture and play around with the PIP input, I get a picture in the PIP and when I reverse the pictures (changing the PIP into the main screen), I get video on the full screen with a black PIP box.
Also, when I pull up the tv's setup menu (which works), I get a t.v. picture in the little viewing box, but when I exit the menu, the blue screen returns.
