Strange Power Supply Behaviour
« on: April 06, 2016, 11:51:44 AM »
Normally if a power supply behaves strangely you'd probably get a replacement, well in this case i replaced all the capacitors and still have the same problem so i wonder if anyone can diagnose the problem.

Basically,
I turn the power supply in my A2000 on in the usual way - using the switch at the back.

Secondly, nothing happens, you can leave it for 5 seconds, then turn it off ..and it's only when you turn it off that it appears to come to life, spinning the fan and lighting the amiga's power LED briefly (about one second). Then it goes off again, but switch it back on, and it'll stay on until you next switch it off, operating perfectly.

So, given that all the capacitors inside were replaced, does this point to some kind of faulty protection circuit?

Thanks! :)

I don't think so, because its only developed this symptom over time, originally it worked perfectly.
