This can be an indication of protect mode. See the link below for an explanation of protect. If you have any additional questions or wich to attempt a repair yourself, please update this and I'll provide additional information.
This is the "protect" mode -- the unit has detected a short circuit in the speaker output and has shut down to keep from burning out the amp.
Remove the speaker wires, then reconnect one at a time. If the LED starts flashing again before you've connected any wires, then the problem is within the receiver. If it starts flashing again when you connect a particular speaker, then the problem is in the wiring to that speaker or the speaker itself.
It shows protect when it senses a problem with the output wires shorted or some internal fault. Try disconnecting all the speaker wires and power up again. If it still shows protect, then the fault is internal.
the protector comes on to keep the amp from further damaging itself or the speakers. The buzz you heard was probably 60HZ line buzz from the main DC supply conducting full current through one of your speakers through a damaged amplifier transistor. Your stereo will need professional repair. The protect circuit basically opens the speaker relay (and sometimes shuts down the unit) to prevent this DC voltage and current from getting to your speakers until the problem is corrected.
es posible que un canal se ha dañado por lo que primero daño el fusible con la sobrecarga y posteriormente se daño el canal. es necesario se revisen las polarizaciones de los transistores para determinar el canal dañado,es seguro que el daño se encuentra en uno de los frontales.
there is a similar problem to yours on here. also, does it take a minute to go into protect or does it happen almost immediately? i'd unplug all your speakers from the back of the receiver and turn it on, if it still goes into protect it sounds like an internal problem which has been addressed. look at this for internal problems; http://www.fixya.com/support/t245043-teac_stereo_receiver_model_agv8520
The protect circuit is doing it's job....probably the amplifier
output stage is shorted.....have a technician check it..make
sure any / all bad connects are soldered when chassis is out
Protet mode is a special diagnostic mode that starts when a fault is detected.
When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.
Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.
Try unplugging power cable for one hour or so. then connect cable back
and see if you get rid of protect state. Sometimes accumulation of
electrostatic charges inside circuit capacitors can kick in protect
mode. In that case unplugging the unit from main for some times can get
rid of electrostatic charges, and reset circuits by draining power
If that was the problem, you will not get Protect when plugging back power cable.
If you do all the above and still get Protect, then there is a real fault.
In that case the unit may be disassembled and tested to find the fault.
If that is the case I suggest contacting the manufacturer at the number
listed on the owners manual, or asking a quote on repair to a local
