Default MItsubishi VS-50605 Inputs not working

Hi,
I have a Mits VS-50605 Tv, and The composite inputs, as well as the
tuners(both of them) , stopped working (no picture, but i do get sound
out of the speakers).
If i use the component, or S-Video Inputs, I get both the picture and
sound.
I have checked the board for leaky capacitors/loose connections, and
everything looks in good shape.

What else should i check/replace?

Thanks in advance,
David F.

First, look for coolant on the signal board. This is a common problem on
these sets. Even a drop or two can create big problems, usually at the
bridge connectors between the signal and PS boards. Then either fix that or
get out your scope and track down where you have signal and where you don't.
The fact that you have s-video and no composite should make it easy to
localize the problem.
