After unplugging headphones from the headphone jack, no sound is coming through the speakers.
Usually the headphone jack has a contact that's "made" by the 'ring' section of the jack when you push in the plug, which bypasses the speaker circuit (that's what automatically silences the speakers when you plug in the headphones when there are no switches to turn the speakers on/off manually)... if the 'ring' strip got bent somehow so it's pressing against that contact all the time, it won't let the speakers' circuit come out of bypass. Look inside the jack with a flashlight... the sideways Vs that touch the 'ring' sections of the stereo headphone plug should be about in the middle of the opening... if they're pushed over too far it may require disassembly to bend them back to the proper position.
Would this still be the case if the display shows when the headphones are connected and disconnected?
It could be a different auxiliary contact that controls that indicator on the display. Did you look inside the jack with a flashlight?
I did and from what I can tell, it looks okay. Disassembly may be required for verification. when I plug the headphones back in, there is no sound through the headphones. Could this be a function of a bent contact or could there be an internal switch not functioning?
Yes - that symptom could also be due to a/the bent contact. Have you tried powering the unit off and back on completely, by unplugging it for 5 minutes, or so, then plugging it back in?
I left it with no power for 15 minutes with no resolution. I think this problem is beyond my capabilities and willingness to continue the effort. Thank you for your help. It is much appreciated.
Well, you could try having a local electronics shop replace the headphone jack... I can't imagine why it would cost more than $50 to do so. Of course, that might not be cost effective if you paid only $50 for it in the first place... but if you paid, say, $500 or more, a $50 repair seems perfectly reasonable to get it working again.
Not a bad idea. Thanks.
