I have an Asteroids deluxe that won't boot up anymore. I suspect it's the main PCB. Who fixes these?
Thanks in advance!
 
Did you check your power supply? That is where you start, checking voltages and AC Ripple. If the voltages on the AR or AC ripple from the power brick is > 0.5 vac on the DC rails, the game won't boot.

You need to check this, or you'll pay shipping and find out your board is fine.

Otherwise, @andrewb is an expert. We have others.
 
the other main easy fault is dirty rom chip legs. clean them and reinstall orientated correctly. If not see the man previously mentioned. damn I sound like the dispatcher on adam 12.
 
AR voltages look good. I get two high pitched beeps, followed by two low pitch beeps after turning the game on. 5v led is illuminated on the main board.

2 High, 2 Low, bad RAM at potentially M3 or R3 or both.

Page 7 of the manual shows this.
