Power supply problem!
I notice that the power supply creates noisy whistle-like sound and the amiga doesn't work..so, what's the problem with power supply?

I had a whistly PSU once... it was the Amiga that was screwed not the PSU. Hope you have better luck than me!

Which Amiga model ?
Original Commodore PSU or modded PC AT/ATX ? AFAIK, high-pitch hissing noise means crowbar protection inside switched PSU circuits had been activated and your PSU is ready for binning. |

Sounds like dodgy caps in the PSU, fixing this could be difficult, not to say hazardous as capacitors can give you quite a nasty shock if they haven't been allowed to discharge safely.
Best to get a newer one from somewhere. Merlin |

power supply
Turn of the power supply at once, you have a short on your supply, use a multy meter on ohms to find it while it is turned off
