a little bit foolish thing: see if you have both the speaker channels (A and B) down. if you have both down it doesn't work - didn't for me.. and obviously make sure you have the right letter down - same outpout as your boxes

Using a higher voltage fuse is not a problem, but if the fuse you used amps are to high, that is a problem. Sounds like a resister burnt. You have a short somewhere in that particular circuit, which is what took out your original fuse. . .your fuse did it's job by blowing and saving the circuit. If you can get your hands on a schematic, you can trace the circuit and find the short.

There must be a diode that is faulty in the power supply section mainly on of the rectifying diodes.
If you look closely at your board you will see four diodes that just after the fuse and befroe the Big capaictor(filter cap.) One of these four diodes must be faulty as the fuse keeps blowing. the diodes are responsible of current limitation drawback. So there must be current flowing back to the fuse that makes it keep blowing.
Check and replace. Good luck
Thanks for using Fixya.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.
