Picked up a Polaris and it boots to this screen

Coin counter clicks when coined up but no change and no sound

Does anyone work on these or I'd buy a working pcb also

In the mean time anything I can check.

I verified power is good to board

I also reseated any socketed chips

Thanks

The coin counters are driven automatically by the credit board and have nothing to do with the CPU...

I've got some spare boards kicking around somewhere, but I need to dig them out and retest them.
 
looks like your cpu is not working. check voltage to the cpu and look for clock pulses going to the cpu and check the reset line going to the cpu. do you have any activity on the address lines?
