I wonder if the AV board is the clue ? Power to it dropping, or sound ROM
flaky. LTG :)

I'm having an odd problem with my AFM and wondering if anyone
understands WPC-S blanking.
When I power the game up after it's been off for a while, everything
in the backbox powers up, and I get a "bong" out of the AV board. At
this point though, nothing in the playfield will light up and the DMD
is off.
After a bit of checking, I found that the BLKING LED (LED201 on CPU
board) is staying on rather than shutting off after 2-3 seconds.
Here's the odd part, though, after 3-5 minutes, the BLKING LED goes
off, and the machine starts its light show (as would be expected) and
operates normally thereafter. Assuming that Blanking is something
similar to what Williams did in the System 7 days and before, I assume
this means the driver board isn't initializing.
Does anyone have an understanding of what's being checked during
initialization, and what sorts of things would be standing in the way
of Blanking being released?
My next (obvious) step is to swap out the driver board and see if the
problem goes away, but I'd rather have a logical course of action.
