Got a Macintosh IIsi computer.
1) Got computer.
2) After plugging it in, it auto turned on? This doesn't seem right, PSU maybe?
3) The screen would show gray, then go off and make an error chime.
4) So I replaced the caps as I thought that might be the root issue (sound was super low as well).
5) Now I have the same issue (but load sound). So computer auto turns on when power plugged in and screen goes on then off and makes a error chime sound.
6) I replaced the ram with "confirmed working" 4 256kb dimms for a total of 1mb but have the same issue.
Any ideas? My only idea is PSU but idk. I also washed motherboard as caps probably leaked but maybe I need to wash more?
