If it is not a bad soldering joint somewhere, it could be the mode switch. They can sometimes be cleaned with Servisol Video 40, but you might have to replace it.

There is a problem in the final stages of the amplifier section that the protection circuits are detecting. They then shutdown the unit to prevent further damage. The most likely candidates are the output transistors. This is a relatively simple repair for an audio shop. Expect a parts cost between $20-$45.

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.

ag-456 vf is black and white only.

the sound you refer to during recording on the ag-456up is probably bad bearings on the video head. unfortunately, this part is no longer available. any good electronic repair shop should be able to clean the lens. a new battery should be available from wal-mart, circuit city, best buy, etc.

I have a Teac ag-7700 and when I would try to power it on it would shut off. I did get it to turn on for about 10 minutes and then it shut off. Now when I try to power it on the light on volume dial stays lit but the LED does not light up and no sound through speakers.

the ag-456 only outputs composite video. if your pc has a video card with a composite imput, you may be able to use the ag-456.

This unit just needs the standard belt job. The rubber parts probably got old sitting around in the back romm of the university.

Could do it yourself if you are the like to take things apart type. Otherwise, a repair shop can do it very affordably.

Hey I think it would difficult to find a manual for a AG-455, though being very similar to the AG-456 (which seems to be more popular) would you be happy with the manual for that model? I downloaded the AG-456 manual from somewhere last year but unfortunately can't remember from where. I do have the PDF file if you're interested though.. Would be happy to send to you if you're interested. Cheers
