TECH: Williams FLASH L.E.D. Question !!!!

[Guest]

Archived from groups: rec.games.pinball (More info?)

I have a Williams Flash machine, and on the 3rd and 4th scoring LED
display, only the top half of both are showing. How do I correct and
do I need to replace the LED displays???

Please advise.

thanks for the help,
Kevin

Hey Kevin,

It's not an LED display - they're gas plasma discharge. Much higher voltage
than LED's is the main reason I'm pointing that out : )

The problem is going to most likely be on your display controller board, which
is the lower left display on your machine. It could also be a connector problem
at that board, or at the connectors on the top edge of your MPU board (top left
board inside the backbox)

Keep in mind several generations are covered here so not all the information
will match your machine. Flash is a system 4.

Check the resistors on the master display board, sounds like a couple
are out of spec.
