I have a question regarding a 35" direct view Mitsubishi TV, Model CK-35402.
This set is in a customer's house quite a distance away and I am hopeful
that I can repair it in one trip.

Symptoms are Sound-OK, On-Screen Menus-OK, video missing in all modes, both
tuner as well as all external inputs. The problem came on suddenly. My
question is this..if it were a common PIP issue, would we not expect to see
normal video when using the aux inputs? If it helps, this set uses the
930B552012 PIP module but I don't know anything else about it yet.

My gut tells me that the problem lies somewhere in the video switching
circuit, not the pip. What do you all think? TIA!
