Then I'd just try to find a way to poke individual components or areas
on that board to narrow down the problem area. Or just resolder
everything.

I unsoldered all 50 pins and removed it completely,
checked for anything loose near the lower part of the board,
and same on the main "A" board. resoldered it back
but problem remains.

Wow, that's dedication!

Because of it's location when it's operational
there's very little access to the board. It's hard to
*see* the components let alone do anything else.

Can you get a plastic stick of some kind in there? That's about all I
can suggest, or try poking the A board underneath. This sounds like a
real hard one.

Best of luck.

Thanks for the feedback. I had attempted to probe the
E1 board with a wooden chopstick but I wasn't producing anything.
Even a freeze spray failed to yield results.
I ended up reinstalling the metal shield for the E1 board, that I had
left off earlier. Put it all back, problem remains.
The A board is held in by 2 screws at the front. The back of the A
board is free to move up and down slightly (until the case is put
back)
Flexing the A board from the back up and down also affcted the
picture, causing it to disappear to blue screen and back again.
IF the fault is on the A board, theoretically, it should be easier
to find.
Thanks,
Dave

Sounds like it's not, it's probably on the main board.
