Re: problem

Please check for any short circuit at the binding post speaker output of the amplifier and also at the speaker inputs.

if all seems to be ok also check the + and -- at the speaker and amp

if this is also ok then it could be an internal problem which could be only solved in a service center by a qualified service personnel.

How can u tell if your internal speakers are blowed?

Hi Patricia,

You may need a professional cleaning of all the switches internally. If you are up to it. Compressed air with an electronic aerosol cleaning solution is the first approach. Over time these parts develop oxidation. The voltage levels are small and the signal cannot be generated.You need to know what too clean, most are visible. You can also look for internal fuse protection. Make sure when the cover is removed to pull the power first. Some higher end Amplifiers provide protection. You will need a digital multi-meter or equivalent to test the fuses.

So before doing all of that. There is a reset switch. It is located between the speaker switches on the face of the receiver. At the top and in the middle left center of the display. Not at the speaker buttons on the left.

That function may be tripped. Reset it twice and try testing with different speakers if it fails again. It may trip instantaneously if there are abnormal voltage levels present in the circuit that arouse protection.

I have located and offer you the Manual PDF. Go here first and try the following. On page 8 in the manual. Titled, " Name of each Control" (D). There is a location diagram for you to observe. Please take some time and look this over.

Finally, if you need someone to talk too. The You Tube Video has an outlet store tied to it that offers live help.

My reciever keeps flashing the word protect what can be done

Protect is the amp's way of saying it is protecting itself from trying to deliver more current than it can. First step is to disconnect the speakers. Have no input signal present (volume all the way down) so it is not trying to put out power. If the protect indicator still comes on, the amp has an internal short or problem and needs professional help. If the indicator does not come on, then you have an issue in your wiring or the speakers. Reconnect one at a time or get new cables and try again. Good luck.

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.

How do you reset the blinking protect banner on the ag-v8520?

Try disconnecting the power cord then disconnect the speakers. Plug the power cord back in then hold in the power button until the unit "clicks." Then disconnect the power cord and reconnect the speakers, then the power cord and turn it back on.

Protect error on agv8500

Hi there. I have the same unit. A darn nice piece of hardware. A couple of months back I noticed my cooling fan making noise. A few days ago I got the "PROTECT" message and the unit wouldn't power up. I turned it off for three days and it started playing again. Now I'm pretty sure it went into protect mode because it overheated. I just tried finding a Teac replacement fan and didn't see one on the web. My solution will be to adapt a small computer-type fan onto it to keep things cool. It works too well to let it die! Good Luck, Gborchers. GROGSTER

Teac AG-L800 'Protect' Error

Since the problem appeared to correct itself on occassion, I would first look for poor solder connections either at the output transistors or at the voltage regulators. Let me know if you need more detail.

Power comes on but speakers do not make noise

Stereo Tech: yes their is a fuse inside that possibly opened, but does the unit show PROTECT across the display? if not you may have goten lucky and just did a fuse small PC board just behind the transformer. Good Luck
