Hey folks. I have a Crusin USA PC B here and I only get the first LED light to power up. No signal to the monitor at all and 1 out of ten times I'll get the first BEEP tone but never the 2nd. I have tried reseating all the socketed ROMS and ICS and cleaned them all as there was visible corrosion. There's visible green corrosion on the legs of the DSP as well. Voltage is fine, monitor works good on a signal generator. Is there anything I should start checking before I swap it out entirely with a known good one? I have another PCB in a Crusin world that I can pull to swap the ROMS. Seems like a waste to use a good Crusin World board but I have 3 Crusin worlds and 2 matching Crusin USAs so I figured it would be better to have 2 matching sets, one USA and one WORLD vs having only 1 set of WORLD and a stand alone USA and stand alone WORLD. I guess I can swap the roms to make sure they're good first and then see if I can order a replacement PCB.
