Hey all you Williams fans out there. I recently acquired a stargate vid and have been receiving a Rom16 and Rom 31 error. as the lcd on the video board will flash 131. I was checking the 20 pin and 40 pin ribbon connectors when for shits and giggles I did a continuity test on the fuses. Realized that the F5 fuse was blown, replace the correct 2amp slow blow 6.3VAC with a radio shack 2amp 250V slow blow and it blew again almost instantly. The LED's on that same power board #1 led non illuminated #2,3, are on all the time.
I currently have
119 vac into the switching power supply
5.02 +5vdc
11.43 +12vdc
F-5 is receiving 10.6 VAC at the fuse instead of the 6.3 that the wiring diagram suggests. now the fuse blowing at that location, would that be the start of my ROM errors and cutting out of the sound issue I have been having. and what should I check next to figure out what is blowing the fuse's at the F5 location?
