So, the problem with my OKIStation is the power supply. 5V is solid... but 12V was only putting out 8.5 volts (with no drive load attempted... unsure if the motherboard uses 12V for anything). I have found there is an adjust for 12V, I have not touched it as of yet. In getting that far, that small pot, 2-3 resistors, a 3 legged "IC1" (NEC C1093) and that area of the PCB have an light oily film on them. The IC1 and the little pot seemed the worse. I'm not sure what this could be... I've never seen a transistor/IC/ etc emit an oily film... I can't see it coming from the trim pot, and even though there are a few nearby capacitors... they don't have a film on them.... and I've only seen capacitors ooze brown scum. If there are no failing components, then either the trim pot has gone dirty... or that "oil" ? has got into it and is causing it to ohm out wrong. As there is no way I'd find another of these supplies, my only option is to fix it. Anyone got any ideas as to the oily film ? Looking up IC1 on the net I find http://pdf1.alldatasheet.com/datasheet-pdf/view/6668/NEC/C1093.html which indicates it is an adjustable precision shunt regulator. In the test and application circuit section of the pdf, this device goes across Vout. If this is acting up, for testing purposes it would seem to be safe to remove it to see if the voltage changes (jumps back to around 12V) ? The oily film puzzles me... I don't see any sign of bad caps... and this power supply seems to be well engineered (has temp probes on the switching transistors presumably to shut down the supply should things get too hot). Being a three board supply design with several connections soldered ... it hasn't been a joy to get apart this far :-) So, suggestions, ideas on the film, and best way to go about troubleshooting the 12V rail are welcome :-) Thanks, -- Curt
