Sometimes the sound will stop playing on my GS-800 and I have to push the magnetic sound button on the front to get it working again. Also, occasionally it lets out a feedback scream. Anybody got an idea what's going on?

Kurt, no guarantee, but the following MIGHT help: take a piece of striped film that you can record new sound on, Then run it in the projector and record, play back, record, play back again. With luck, this might help! [Smile]

I´ve been lucky with this trick on everything from Elmo GS 1200s to consumer video camcorders to professional betacam VCRs. They´re all constructed with one huge switch in them to go from record to playback, and any corrosion, glitch, etc in this switch will wreak strange havoc on the machine.

Oh, and Kurt, be sure also to insert/withdraw a headphone plug in the headphone socket "about a hundred times" since it´s in the same circuit as the speaker. You may want to do this to the microphone jacks too. Any small corrosion here can lead to problems.

Cheers
Lars

Hi Kurt
I had the same problem on a ST180 it turned out to be a dry joint on the amp board.

Lars, I think it's working! What a relief. It screamed once more so I repeated all the processes again and it seemed to settle down.

Christopher, what's a dry joint? I can check into that too.

Lars

A dry joint is where solder on a componant has dried out so connection on the board is bad .
