Electronics Repair Questions? Ask an Electronics Technician
Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.
Does your home theater have a 'CD cassette' or 'carousel' for multiple CDs?
If so, it may have jammed. Shut the device Off, unplug it, and wait 2 hours, then try again, first doing an Eject of the CD or CDs or cassette that is/are already in the machine.
As for audio from the TV... how is the home theater player connected to the TV? through an HDMI cable, or through RCA cables (the ones with colors on their plugs) or other type of connection?
OK. To get audio from the TV, go into the TV's MENU system, and go to Audio Source (or Audio Settings, then Source, or the like) and select the input that the RCA cables are hooked up to.
(I'd try the RCA inputs first, since HDMI cables of the cheaper vintages are often subject to poor quality problems, such as not really working, not transmitting audio, etc.)
See if RCA input being selected on the TV, allows audio through to the TV. Let me know the result, please.
Check that the home theater is not Muted.
Check that the TV is not Muted either.
Turn up Volume controls on both the TV, and the home theater system.
(If either one has its volume very low, normal volumes on the other one will be either inaudible, or else very low volume. The two devices' volume controls work together, and one can severely limit the other.)
Good to hear that the jam has been overcome!
What external speakers do you have? the ones that go through the home theater?
Also, try disconnecting the HDMI cable. If defective, it might be keeping down the audio somehow, perhaps. It's one thing to try.
Does the TV itself work, when disconnected from the home theater, as far as sound (in its own speakers) goes?
OK. The problem isn't in the TV then.
What outputs on the TV, are the RCA cables hooked up to?
What inputs on the home theater system, are the other end of the RCA cables hooked up to?
Turn the system components Off by all means, when switching or disconnecting cables.
