I have a DSP 508A type PSU in an STE which looks like it hasn't been used that much
This problem randomly started the other day, after some use it switched off and then on again, so i changed all the caps and now it switches on and off very fast so obviously the computer doesn't start at all
If you can imagine the green power LED goes on and off constantly, say on/off in a second constantly in a loop
I have since changed the caps again and the same problem
I have also changed the BU508A transistor on the heatsink and the opto coupler, same problem
Does anyone have any idea what else i could look at?
