What can I do with a amp tuner fisher rs-851 in standby?

If by "standby" you mean the amp is trying to power up, check for speaker protection issues. Speaker wires and/or speaker issues may be causing the speaker protection mode to keep your Fisher speaker lines disconnected from amp.

Protect mode

The most common cause of this is that one of the speaker voice coils is shorted or the wiring to one of the speakers is shorted. Disconnect the speakers one at a time and see if the amp goes out of protect, if no change you have a shorted output circuit in the main amp section.

When I push ON button I see in display " protect" mode...

It could be a short in your speaker wire or the crossover in your speakers.

1) Turn off your unit and disconnect your speaker wires at the amp, if the protect is no longer displayed when the unit is turned back on, check the connections on the speakers. If you do not visually see a short on the speaker wire connection, turn off the unit and disconnect the wires at the speaker and isolate them so they do not touch then connect the speaker wires at the amp. Turn on the amp and see if the protect is on. If it is on, the wire has a short somewhere in the line. If the protect is off then suspect the speaker has a short in the voice coil or crossover.

2) If the protect is still on after you disconnect the speaker wires at the amp, it could be the power IC in the amp is shorted and needs to be replaced.

My receiver gives me a PROTECT message when i turn the volume up to high and it shuts itself off what does this mean? this started after i hooked up a subwoofer

There is likely a problem in the power amp section that only becomes apparent when the increased volume demands sufficient current in that stage to push the amp into a potential component failure situation. The protect circuit clicks in and disconnects the speakers from the amp to protect them from damage should the power amp stage experience a catastrophic failure. Unless you are a trained technician, you should have the unit repaired before major damage occurs.

protection is designed to protect the output transistors from, shorted speaker wires, shorted speakers, too low speaker impediance,make sure the amp is well ventilated.
turn the amp off for 1 to 2 hours to allow thermal reset if this fails most likley some internal damage has occured and the unit will need to be serviced

Amp output is damaged and needs repaired. Protect mode cannot be deactivated. When amp is repaired and operating normally protect mode will not be displayed.
