Hi everyone, I recently picked up an SE/30 that was working when I originally powered it on, but it is now displaying strange symptoms. When powering the machine on, it either gets to the no floppy screen but restarts and proceeds to play the startup chime multiple times in a row. It sometimes also will just show a white screen with crackling coming out of the speaker. I assume this machine just needs a recap and cleaning, but could this also be an issue with the power supply? I was using it to test hard drives when it died, so maybe that caused the problem. Thanks in advance.
