Very strange behavior with my(Jomac calls it an Orion PWB-2022 but Ken in an earlier discussion said SI\Kortek)that showed this same symptom with a Mr. Do board as it's now doing with my Capcom 1942.
OK...everything looks fine when first powered up. Then within 10 seconds with the B+ at minimum-the screen goes green with retrace lines and I can see the game running in the background but its mainly white. If I turn the B+ up at all I get the green thing even after a cool down restart.
I notice the big sand resistor(no markings)right next to the filter cap gets really hot compared to my G07's or WG's. I can't seem to find any schematics for this chassis so I'm winging it here.
Could this be a failing voltage regulator or the sand resistor breaking down? Or??
Any suggestions would be greatly appreciated
Thanks Ben
