Question about Audio Players & Recorders

1 Answer

Indoor home stereo receiver by Optimus. Model Stav-3150 25 years old. Radio connections on back will not stay connected. I can JIGGle the connections on back after 1st loosening the plate they are attatched to. Some times if I push on the connectors and hold them inward I get a connection. Soon as I let go of the push. I am back to static. The connection never lasts long. Can this problem be fixed?

I believe it can be fixed fairly easily. You'll need to find someone who had experience soldering. Don't use a novice for this. They will need to open the receiver up and resolder the connections where the antenna connects just behind where you are pushing to make it work. The wires are probably broken but sitting very close to where they are supposed to be connected. They will have to be stripped a little bit (insulation carefully cut away) to expose the wire conductor inside to reconnect and solder them. Make sure they use Rosen core solder, NOT acid core. Acid core is for plumbing and will eat the connections away. Rosen core solder is for electronics.

SOURCE: Mismatch of stereo receiver outlet to connector wire.

There are adapters available at Radio Shack for connecting almost anything to anything.

Not knowing which connectors you have, I can't tell you what to get, but if you take what you can with you and explain the rest, they should be able to give you the correct adapter.

Optimus STAV-3260 Digital Synthesized A/V Surround Receiver. this receiver has no power,not even a light for the standby.i already checked the fuse and its ok.


Could be several causes. Bad connection near the stand-by power transformer or the transformer itself could be open. The main Micro could be bad. This is a job best left to a servicer. Optimus was sold only by Radio Shack, they still do repairs.
