Question about Teac A-1D 2-Channel Amplifier

1 Answer

TEAC Amp I actually have a TEAC AG-7D amp but I'm hoping the problem might be a generic one. When I turn it on, it automatically turns itself off a few seconds later. I have disconnected everything and this still happens. Can you help?

Re: TEAC Amp

The amp is going into "protect mode". This means there is a bad part or parts being detected. Professional service will be needed.

I would like to find out how to play audio from my panasonic viera tx-40cx400b tv/other devices e.g. xbox one etc through to my Teac A-H300 amplifier.

Having looked at the TV, you will have a lot of problems trying to connect to that amp. The TV has a digital optical out output only. The disc player you mentioned will also be out only. You need a optical "in" for them both. The TV has no analogue out sockets. The only chance you might get any sound out is via the scart socket. If that is fully wired, then the scart might produce L&R analogue out. A scart plug with RCA connections (make certain it has both audio in and out) might produce some sound for the amp.
Otherwise no chance!

The amp you have was not made to work with digital signals. The TV will produce high quality Dolby 5.1 sounds. Assuming you get the scart to produce the sound, then you will only get stereo sound, little better than the TV itself!
I therefore recommend you get a decent digital amp that you connect all your future devices too. One that has HDMI connectors as well as at least two optical inputs.
Onkyo make some excellent models. For example this model would do the job Onkyo TXSR444 Home Cinema Receiver.

Connect the intergrated AVampliphier TA-VE215 to TEAC LEV32A1HD tv dvd combo

Connect from the TV's headphone output to the amp's "TV" inputs (3.5mm stereo to two RCA's). Connect speakers to the amp, and select "TV" at the amp.

My teac MA-7 amplifier makes a very loud bang (rather a very loud clicking noise) a few seconds after I turn it on, and then every 5 minutes or so. Even with volume all the way down, even with no inputs...

All I can tell you is that if the noise is on both channels the cause of it has to be something that is both channels running to it or is something to do with the power supply. If the main amp channels are outputted by one device I would blame it on that. But if they are separate you will need to look elsewhere.

I have teac a-H5001 system the amp just stopped working no lights showing but I am still getting power from it to tuner

I fear that the power amplifier wwould have failed or blown a fuse in the main supply. You will need to open out the set and check for the fuse witthin. Disconnect the set and open the panels. iff the fuse seems ok, the use a multimeter to continutiy test for the output. if you get a shorting then the outputs have failed and needs a replacement. If all these sections are fine your will need to check for the microprocessor which must have gone faulty. check for +5 volt to the PC, then check the crystal oscillation. You must probe into these two sections to come to the main problems. Hope this helps . Good day

I have a TEAC 500 amp. It just cut out when I was listening to music. Now there appears to be no power (unit does not light up), but the power outlet sockets are still powering the other components - so...

More than likely, the internal regulated power supply has gone bad. The power outlets going out are usually just straight wired from the incoming power source, and not run through the power supply. Good luck!

Looking for circuit schematic for a Teac AG-7D. There's no visible burning on the board, no blown fuses, the power light comes on, it just won't make a noise any more.

This unit has detected a problem in the output section and the protection circuit is preventing the output relay from turning on. In most cases this is due to shorted output transistors which will need to be replaced. If you have a multimeter, set it to read DC volts and measure the voltage on the three legs of one of the output transistors. You should read .6V, 40V or so and 0.0. I suspect that you will read 40V on two fo the three legs. If so, that is your problem. Please note that the actual reading for the higher voltage may be something other than 40. I don't have the service manual for this model, so I don't know the exact voltage. It will be anywhere from 35V-75V depending upon the actual design and output transistors.

I am not aware of the availability of schematics for this unit, but any shop that works on audio gear should be able to repair this without them.

Teac legacy AG-800 AV receiver.

Hi most amplfiers have DC offset and short circuit protection. Since you have removed all the loads it should not have a short circuit on it, the other possibility is DC on the input so I would recomend trying disconnecting the inputs as one of them may have DC on it, however this is unfortunately unlikely. The most likely cause is that the unit has gone wrong and the power amplifer is faulty. One last thing you could try is too open the unit up and make sure all the cables and PCBs are connected properly sometimes a loose connection can cause this type of fault. Failing that, unless you know how to fault find electronics, you will need to take it to a repair center or replace it. Regards, Andrew
