Ok, have a star wars cockpit and having some trouble. I have no sound, no picture,no coin up, no nothing, except slight hum in the speakers
> I have a power supply that has been rebuilt, tested and working
> I have a audio/reg rebuilt tested and working
>I have deflection board rebuilt tested and working with upgrades
>I have a hv board tested and working with upgrades to it.
Now on the pcb boards I noticed 2 out of the 3 red leds in a row are on constant. When I go to jump the watch dog, I hear and see the ticket counter jump 1 number and 1 led goes out leaving 1 constant on in the row. Still no sound,picture,coin up, etc....If I dont jump it, the red led comes back on. Now nothing works in the test mode either.
>I checked all the voltages on the boards, 5.1.....-5......+12...etc, all votages good everywhere....
> I re-seated all the chips that I could remove.
>I cleaned all the edge connectors, and even tried it without the shield on
Suggestions on what to try or what could be the cause?
Thanks and any help would be great
