Hi. For what it is worth, something I have learned about this problem, as I
have one to play with. I have found a workaround that works like a champ,
provided you have the A/V jacks on back and either a vcr, digital cable or
sat box. Take the output from your box of choice and connect to A/V jacks.
Then switch to A/V input with remote. The sound problem doesn't seem to
affect these jacks, and you get a sharper picture to boot.

I tried disconnecting the GEM module, which seemed to do the trick, but in
reality it didn't, as I had unplugged set to try the idea out.

I will see how the A/V bypass does, but no complaint so far. I know it isn't
a fix, but it was the only option available to me, see below.

I know it is some signal sent from the broadcaster, with 2 too many bits, or
some such, that overloads a buffer. I had considered doing the cap bypass
but couldn't, as the owner is 85 years old, has 2 hearing aids, and
deinitely uses closed caption.
