Vibrations from moving often cause solder connections to fail. Check with a magnifying glass the solder connections on the PC board on the audio output chip for hairline cracks and resolder. If you are not profeicent soldering PC boards refer to a professional.

Can't get volume on jvc hd 52g786


This set is prone to the audio board inside failing---all the audio is on one board, last one I replaced was just over 100 dollars.

No sound


I have seen several of these (some brand new) where the audio board fails, if I remember it wholesales for just under 100 but is not real easy to get at---entire audio circuit is on it.

No sound trough the tv speakers on JVC model 52G786


either speakers turned off, or an audio problem which was common on this model----the entire audio circuit is on one board which may still be available.

I have a JVC HD-52G786 and bought it in 2005. The other day we were watching it and the sound just went off. I checked all cables to make sure they didn't come unhooked but still now sound what should...


I presume you have no sound via the a/v inputs as well as cable or coax input.


We do factory work for many brands including JVC.

I remember one of these sets only a few months old with no audio, JVC exchanged it as the customer was angry (understandable). Ten minutes later we get a email and a call from JVC telling us set has been exchanged and they do NOT want the old one back---do whatever we want with it.

I had tested the set, following the audio circuit to a single board that supplies all audio--board was not real easy to get at and was on "backorder" meaning lots of them were bad and JVC was out.(which is why the set got exchanged).

I had the board ordered and about ten days later the replacement arrived--installed it (it was sandwiched between two other boards) and set worked perfectly===we ended up with a nearly new set (board wholesaled for about 80 dollars) and sold the set used with an extended warranty.

My point is if no audio from tuner or rear inputs it is a shop repair as most shops will not tackle this problem in this set IN THE HOME..

If you have audio from ANY input it may not be the set.

Let me know if you have questions, I am here to help you.

52G786 ATSC Tuner no longer works


I have the same exact model tv...Love it...ATSC tuners is in definition an Analog tuner. As the broadcasting companies change over to Digital broadcasting before the deadline in Febuary 2009 more and more local or Non-Digital chanels are becoming obsolete. You would have to purchase a converter box for your tv if your not planning on getting cable. Another way to gois if you have an old cable line running through you house (no incomming cable) plug you tv into that jack. That also acts as a antenna. The sweet part of all this is that your tv do have a QAM tuner or Digital tuner built in just need that digital antenna to pair it up.

HD52G887 no sound


Hmm.. If you have your television hooked up via component connection.. you may be forgetting the audio cable. This is a very easy mistake to make while component cables usually dont come with audio or optical audio cables.
