Zenith SJ2743LK - no audio

[joelr]

Hello All,

I have an old Zenith 27" SJ2743LK that still has a good picture but the sound is completely out.

The other evening, everything was fine and then the next morning, there was no sound! Eventually (maybe after an hour or so) the sound came back on by itself.

It worked for a few days and now it's out again and I think for good.

I suspect that if I replaced the Main module, 9-1054, it would fix it, but thought I'd check with this forum for any other suggestions.

Any ideas? - thanks

Try replacing rx820 a 1 ohm resistor first.
