Hi everyone, this unit turns on and then shutsdown. During the on time a display appears "F61" and then shutsdown. Not real sure what it means, I don't have a schematic on it. I think it may be a error code. If anyone can tell me what this might mean, that would be great. I checked all fuses, main and pico that I could find. The secondary of the powersupply seem to be putting out the appropriate +/- voltages but I don't really know what they should be. Any suggestions would be greatly appreciated.
