Question about Teac AG-D9100 Receiver

1 Answer

Hi there i own a TEAC AG-D9100 and have only had if for about a week and when i moved my unit and set it back up i was connecting my speaker wires when a small strand of wire touched the back of the reciever that now stops it from coming out of safety mode i have replaced the fuse that blew and as soon as i turn it back on it will blow the fuse. I was just wondering if you had any ideas of what else this mishap would have hurt and if its worth getting fixed? Any input would be greatly appreciated, thank you for you time.

Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.


Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.


You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.


If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.


If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Just take it to someone who can give it the sniff test in person. No one using a crystal ball over the internet is going to nail the problem or the price for fixing it.

Teac Ag D9100 Receiver how to install a equalizer


I'd connect it between the "Tape 2 Monitor" jacks. On the TEAC, the "Record" jacks are audio OUT and the "Play" jacks are audio IN.

Connect the Record to the EQ's IN and the Play to the EQ's OUT.

Select your source (AM, FM, Phono, CD, etc. and when you select Tape 2 Mon, you'll pass the signal to the EQ to shape the sound of the source. With it unselected, you'll bypass the EQ.

Check your speaker and speaker connections. Do you have normal display? If so, after checking your speaker and speaker connections and they are ok, you might have a problem with one of your output elements (Mosfet).

I have a Teac Receiver AG-D9100, sound cuts off, but if I touch the master volume knob it comes on for a short time. What to do? jmf


This can be related to a fault in the potentiometer as it cut off the tracking of the voltage and gets back to feed the digital circuit. You need to check, sometimes a switch cleaning oil can help.
Try to wriggle the pot control many times as it can help, if not replace.

You have to enable them and turn the volume on them up separately with the speaker config, level trim, and up/down select buttons on the remote. You can also adjust the rear speaker delay time or just hit the test tone button and adjust the volume on each speaker separately as it goes through them one at a time...

Yes, and if you have a cable/sat/dvr box why don't you just run ITs best TV-related audio into the receiver without watering it down through your TV?

I'm not so sure that running the TV video through anything else serves any purpose. Once TV has it where else do you need it?

Something is shorting out and tripping a safety feature that protects the amplifier from damage.

try a few simple steps to see if the problem is internal or external.

First make sure that none of the speaker terminals have any loose strands of wire that could be grounding out the terminal and that no wires from the red terminals are touching the component or the black terminals / wires.

secondly disconnect all but one speaker test it to see if t causes the amp to go into protect do so for the other speakers until one trips the protect mode. If one of the speakers is tripping the protect mode it could be a damaged / blown component.

just for fun make sure your speakers are 8 ohms this can be found on the manufacturers website or in your manual. Its rare but some speakers are 4 ohm and they can cause amplifier issues such as tripping a protect mode.

You may have to evaluate the "value" of the receiver and determine if its worth repairing. Many shops will charge a "diagnostic" fee which may be $40 to $80 and remember that parts and an hours labor may not make good financial sense especially if you are talking a unit that is 5+ years old.

Hope this helps
