Hi all,

This is very unique situation, the sound from my ST-1200 has just gone. It becomes a silent projector now.

I thought it would be the amp has gone kaput. But when I hooked my active speaker up to the earphone plug found at the projector, the sound came out OK.

I have checked if the connector from the amp to the 2 internal speakers has done something wrong, but they were just OK.

So what might be the case?

Thanks

It could be much worse, Winbert!

-it sounds like most of your sound system is still working!

When you take the back off one of these, there is no plug like other Elmos: it's two metal contacts that press on two other contacts on the machine chassis. These could be making poor connections.

There are a DIN external speaker jack and a 3.5mm aux. socket. Both of these are capable of interrupting the internal speaker. You may be able to restore the connection by plugging/unplugging the right connector a couple of times.

It reminds me of this one:
