How old is your set? Prior to HDMI becoming so readily available, the "average" TV had several different types of video & audio connections. This meant as many as 4 additional cables bundled together! Several years ago (especially when TV shifted from analogue to digital) more & more TV's incorporated DTI's (minority) and HDMI. Since the HDMIs allow higher data rate, meaning more pixels, high definition broadcasts could be enjoyed. Plus the cable also carried the audio signal as well.
To know more specifics, search for your manufacturers website ti research your model number. Odds are, it is no longer made and no upgrades are available ( cost).

There can be lots of things in the whole audio chain that can be wrong, but I limit to things you could try and test yourself.
You could switch the sound switch, where it says Hi-Fi Sound several times, up and down and then check if on any setting you hear something. (lift the view finder up. I thought it was the switch to the front.
Then you could try to put in a headphone, and listen if you then hear any sound. If the switch behind the plug is oxidised the sound is gone too. If you hear sound in the headphone you know almost every thing is working. when you unplug the phone and you again hear nothing, plug and unplug several times. Difficult to clean it yourself, because you could cause the oxide or other debris comes in the camera.
Then you have a video / audio output switch right side to the front, try switching that one too, several times. I hope you get the old baby working again.
if you know anything about the tv, take off the back and remove the power supply board. Reflow or resolder the solder points, takes like 2 hours, but is well worth it as my tv works fine now. make sure to use rosin core solder and good luck
If the low impedance light is on, the amp probably has shorted output transistors. If you don't know of a good local repair shop, call 'several' of the local audio sales/installation shops to see who they use. If more than one audio shop recommends the same repair shop, they probably do good work.
I had the same problem (CD mode) but today all audio is gone.
I opened it up and found no visual problems. There are 3 main boards inside, one where all audio inputs go to. I think that board is bad. Not much help I know. Good luck finding the answer. I'm doing a search on know problems now, If I find anything, I'll post back.
