For the last couple weeks I've turned my TV and receiver on only to see the picture in the top left part of the TV, roughly 1/6 the size of my TV. I have a 50" and it shrinks to roughly 19". I can press guide and get my guide to come up normal, but the picture stays the same size. Nothing changes the size, I press the format button (#) and it loses contact with my receiver and a hard reset has to be performed to get my picture back, which it then comes back to normal. I would say 1 out of 3 times I turn my TV on, get this problem. Any pointers? It's getting real annoying having to do the hard resets.
