Check that your speaker wires are connected properly, and none of the wires are touching. if this dosent work hold the sur mode and tune mode at the same time with the unit off(in stand by mode) and this will reset the receiver

I have a Harman kardon 1700Avr that is stuck in protect mode, Is there anyway to bypass or reset it? Thanks....

It's in the protect mode because of a component failure inside. It needs to be repaired to get out of the protect mode.

Protect message

Protect means that a fault was detected, disconnect all the speakers

and connect one at a time to find the cause.

If symptoms persist , it needs repair, output stage or power supply

circuits should be the preliminary things to check.

Trying to hook up sony s-master with componet cables an the s-master displays on the display ''PROTECT UNPLUG'' however with nothing plugged in the s-master, works fine

Check speaker wires, any wire seems shorted and causing Protect Unplug error message in receiver.
Good way to sort out bad wire is plug one speaker at a time, turn On receiver check, turn Off, then plug next speaker wire until you find out what speaker wire activates protection circuit of receiver.

Remote control stopped working.

Hi forlillis,

1. Make sure there are fresh batteries in the remote, and they are installed correctly.
2. Make sure the area between the remote control and receiver is not blocked by some object,
and the distance is no more than 15 feet at an angle no greater than 30 degrees from the
front of the receiver.
3. Make sure strong lighting is not directed towards the IR sensor of the receiver.
4. Press each button on the remote and verify proper operation.
If these steps are taken and remote control still does not function properly 
5. This step discharges the capacitor and resets the remote control. (You do not need to point
the remote control at the receiver or even have the receiver turned on.)
A: AVR35  Press the TV and the M4 buttons at the same time and hold for 12 seconds.
To Test: Make sure your AVR35 is ON, press each button on the remote and verify
proper operation of your receiver.

Let me know how it went.

My receiver is flashing "protect" how do I reset it

The protect message indicates that a problem was detected at the final stage of the amplifier and the unit has been shutdown to prevent further damage.

If the unit continues to flash protect even with the speaker wires disconnected, then the problem is internal to the unit and it will require repair not just a reset. The typical reason for this is shorted output transistors. Expect a repair cost of $25-$45 for parts if it continues with the protect message.

Please keep us posted.

It senses an error or problem and shuts down. Try disconnecting all the cables and wires attached to it. Try it again. If it still shows protect message, it is an internal fault and requires a repair shop. If it clears up, then the problem may be a shorted speaker wire. Correct the short when reconnecting the speakers.
