I purchased a power supply and composite cable off ebay and now that they have arrived it is time to test. I don't have a floppy attached yet but I expected to see a "Put your Systems Disk int your Disk Drive" when turned on. Using a RF modulator plugged into a TV, I get snow, then after turning the 520STm on, get a black (or dark gray) screen for a few seconds, followed again by the snow screen. I have re-seated all of the socketed chips already.
Your troubleshooting suggestions would be appreciated.
