If you keep the volume below 20, the unit works fine, but as soon as you increase the volume above 20, affter a few seconds the unit switches off and "F76" flashes on the screen. It is most annoying as Volume 20 isn't very loud. Is it an adjustment in the amp or power supply?If you keep the volume below 20, the unit works fine, but as soon as you increase the volume above 20, affter a few seconds the unit switches off and "F76" flashes on the screen.

This is a protection mode. Always look at the back to see the correct resistance of speakers to use and never double speakers up. If you wire it up correctly it will not trip out. If it trips out anyways then it is time for servicing.

There are two types 300 ohm and 75 ohm. Some amps have both types of connection. The 75 ohm type use plugs and cables commonly used for TV aerials and Satellite dishes. The 300 ohm type uses screw clip terminals where you attach a coloured cable. All shown here: The FM socket with the thread on, uses a Satellite connector plug.
F61 is an error code. It will automatically shuts down your unit. This is very common on your unit.
Try to checked if the fan is working or not. I have repaired some unit before, this is the caused why f61 appeared. The symptom is shutting down the unit after a few minute. If the fan is not working it will shuts off automatically to avoid further damaged to your output I.C. from overheating.
If confirmed that the fan is working then I've suspect that your output I.C. is shorted. This is quit technical and need to send to repair shop to isolate the faulty parts. The output IC of your unit is RSN series and quite expensive.
ANY amp will be ok, as long as the wattage of your new amp does not exceed the wattage of your speakers. Otherwise you could overdrive your speakers and damage them. First clue, if you turn up the volume and the speakers start to shut off and on you are pushing too much power to them.
I Have a panasonic mdvd home theater modl#SA-HT920, WHEN I RAISE THE VOLUME IT SHUTS DOWN AND INDICATES F61 ON THE LCD SCREEN HOW CAN I SOLVE THE PROBLEM
The source volume is too high or output from source is too powerful or the receiver is damaged. Try turning the volume down on the source device (cd player/dvd/satellite receiver etc) and recover the overall volume by turning the amp up. Also if the source device has any tone controls, return them to a flat setting, again using the amp to recover the sound richness.
If the sub has a volume control, turn it down then turn up the volume on the amp to the very high volume you mentioned. If it still has very low muffled sound, then we know the problem is about the amp.
