Williams Stargate no display or Rom bd segment display
I'm about to dig into this a lot deeper, or as deep as I can, but wanted to check here if anyone knows a common resolution to the issue I'm having.
No CRT display but have filaments glowing and high voltage, no 7-segment display on ROM bd on power-up, Sound bd diagnostics seem to work by pressing diag switch on bd, voltages off of power supply correct with no AC leakage, no reponse from "reset" switch on CPU bd.
I've swapped out the main boards mounted on rear door from another unknown if working Stargate, but no change. This did not include the sound bd.
Is there anything anyone knows of that I may be missing that should be obvious before I spend a ton of time tracing supply voltages?
Thanks
