Hi Mike, the model is a dynex GXL42 10A and no, there was nothing plugged in... it appears there was a telephone used to program it originally that is no longer available so the password ***** ***** don't know if that hampers the ability of tv to turn on the sound but we can do everything else... the audio is turned "off" in settings...
Expert:  Mike G. replied 1 year ago.

when was this tv purchased?

where did you get that model number? it's not coming up as valid.

what do you mean by "a telephone was used to program it"?

Expert:  Mike G. replied 1 year ago.

maybe it's at DXL4210A....

do you have the original Dynex remote and can you bring up the menu?

Expert:  Mike G. replied 1 year ago.

Please try this using the Dynex remote:




follow on screen instructions to complete the reset.

exit the menu.

if the audio is not working, unplug the POWER cords for tv and any related equipment like cable/sat box for a minutes, plug them back in and test.

If that doesn't help then the tv needs parts and service. In this case the Main board has to be replaced. If that is something you want to attempt, reply back for assistance. Otherwise it would be better to replace the tv because repairs by a local shop would cost too much.

Before you go please take a moment to submit at least a 3 star rating at the top of this page. Then if you still need help you can reply back and I will be happy to assist you further.
