System has power and cd's spin but no sound coming from the speakers. checked all connections and tried speakers with a different system they work fine. Please advise, Frank

The radio has an amplifier? and you are sure there are speakers connected?

check all jack plugs are in the correct places and speaker connection wires too.try turning your tuner on to test the speakers that way for sound,if sound is heard through the speakers it could be a cd malfunction.if nothing works contact your dealer.

if speakers are connected sorrectly and you have no sound from the radio your build in power supply is prob bad. call the manufacturer for warrenty or just buy a stereo

I am sorry that your cd player must have a weak laser output, the optiical headd is defective if you have tried to clean and not had any result. clean one again to confirm. Now the next thing you must do is to put your set on for another 24-48 hours. let the electronics within get charged up. try it out after 12 hours, 24 hours and so on. If this wont clear then your Cd optical needs a change. Now regarding your L channel , it is important to see if the speaker connections are tight if your L speaker works in the R side then the speaker is fine. if not check if your speaker is faulty and replace. if not check within the amp for a faulty L output amp circuit. I hope the set will power on after some time. Good day

To troubleshoot:
- check connection of player to speakers
- check if the volume is at minimum level or mute
- check if player is in CD player mode

the speak power system may be burnt out, to check that you need to plug the speakers into a wall outlet and connect the speaker to a boombox (CD player) audio jack out. play some music on the cd player.
if still issue no sound...then check if the power cable of speaker is ok.
take it to a tech

Remember seing something under one of the seats ,but in my old age it could have been a cd autochanger

Sounds like a grounded speaker, disconnect each speaker and see if the sound comes back on through the remaining speakers connected. Its sounds like it is just in protection mode from a chssis ground. I hope this helps!
