Time Pilot - Monitor pulses, displays text char. No coin-up or sound.

[bfrosty]

I had my Time Pilot working just fine, then it started to pulse the screen and display text characters.  Tried new power supply and didn't help.

The machine won't coinup or put out sound.

I'm thinking a lose connector on the PCB/Harness.
On the label it states: Wells Garner 19K4675

What do you guys think?
TIA

Test voltages on the board at where the connector connects to it, if bad, check the wiring that goes back to the power supply.  If good and there's no obvious trace breaks or bad capacitors on the board, you're probably going to need a board schematic.
