The right channel on my Optimus STA-3500 speaker does not work

The right channel on my Optimus STA-3500 receiver is not working properly. It does not output to my speakers. If I shake the receiver/wiggle wires/just mess with it, i can sometimes hear noise trying to get through to my speaker but with little success. This happens with both A and B speaker outs.

If your new reciver does not have a turntable input, you can purchase a phono preamp and simply plug the turntable into the preamp and the output of the preamp to an aux or tape input of the new reciver. they should have it or be able to get it at radio shack. Or look up online or build one as I had to do as im a cheap skate, but I know what I have now..Check this out. i included the preamp i built so i can still use my collection of vinal with my surround sound system. Good luck and please dont forget to rate this thread.

SOURCE: My Optimus STA 3190 has no AM/FM

Hi rowdy

The fact that you are getting static at least is good. Without knowing allot of the background to your problem, first thing to check is if the aerials are correctly connected. If it is any help to you, here is an excerpt from the original owners manual about the connection of the AM loopstick.
If the aerials are coinnected right, then let me know and we can investigate other options. Cheers

SOURCE: How do I reset the protection mode on my Optimus

You can not "reset" protection mode. This is an indication of a defect. Disconnect the speaker wires completely and if the protection mode remains, then the problem is internal to the unit and is likely to be shorted output transistors. Expect a parts cost in the $20-$50 range for this repair.

SOURCE: I have a Optimus STA-3750 am/fm stereo receiver

I have the same receiver, but have been unable to program it with my Universal Code. I do not have the original remote. Did you find a code that controlled it? I found one website that had the owners manual online, maybe that would help: http://support.radioshack.com/support_audio/doc58/58124.htm

No sound on left channel on home stereo optimus sta-795 will changing fuse out restore sound


Not likely! Suggest swapping input connection, red RCA connector to white and white to red and see if problem swaps speakers.

If still left channel bad swap speakers left to right see if problem follows speaker.

Check balance adjustment and confirm that it is set to the middle!

Check all other inputs and confirm always no left output.

The goal is to confirm that the left channel is defective!

The service manual is MS3102101 would normally be available from Radio Shack.

Check for defective capacitors or failed solder joints on the PC board. These units are repairable even by DIY however replacement recievers are relatively inexpensive.

Hope this helps?

I have an Optimus STA-3500 Digital Synthesized AM/FM Stereo Receiver. If I buy an i-pod is there a place on the back of the receiver that it can be plugged into? If so, what kind of i-pod wire/cable...


It won't have "iPod" functionality but it can be played through the receiver.

Any audio device that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input (except one labeled "PHONO"). Get a cable like the one described here: http://www.monoprice.com/products/product.asp?c_id=102&cp_id=10218&cs_id=1021804&p_id=665&seq=1&format=2
and connect it into any available analog input EXCEPT one labeled "Phono".

The volume is barely audible even with it turned all the way up. I have tried different audio cables. It occurs in different modes also, CD Tuner, etc.


Maybe you have it muted or a Tape Monitor engaged??? Never troubleshoot anything at high volume. If you can't hear it at medium it's effectively noth there. A flip of a misplaced switch would possibly blow your speakers.
