You have a scope, why not track down the faulty component on the board
rather than replacing the whole thing?

Hi. I need a small signal board for a Mitsubishi WT-46809. The one I have
produces no video, no menu, just retrace lines. Does have sound, so tuner
is fine. Regulator outputs are where they should be -- 9 volts 3.3 volts.
Board is dry, no tube oil leaking on it. I cannot find anything missing. I
scope video in and out of terminal board and comb filter board, but no
video out of signal board to tubes, just a bunch of trash, looking like
maybe half a volt signal filling the entire gap top to bottom, no sync or
video signal at all.

This board uses 2 standoff boards -- a smallish comb filter board and a
somewhat larger 2HDW board, as an assist in seeing if you have one. There
is another version that has a slot for a PC interface. I could use that
one in place of this one.

Also has 2 tuners, and 2 wide connectors for terminal board.

I don't have it in front of me, else I would give you the number off of
it. If you have one of these sets, 2000 model, or thereabouts, that you
can part out, with a good signal board, please drop me a line.

Thanks, Danny
