Ed, Yeah I thought about the filament voltage at first but it doesnt make
sense that the menu is still present after the picture goes out. So its only
the video that dissappears, what caps are most likely to cause this problem?
Are they surface mount? I have no information on this chassis, can you help
out? Diagrams, schematics, tips, anything...Thanks a bunch Ed.

David;
This is the C8S chassis. Without seeing it, hard to say, but sounds like
probably a bad connection on the board for the Filament voltage. Unless it's
only the Video that dissapears, then you got some bad Caps to contend with
in the Video circuit.
