52G786 ATSC Tuner no longer works

I have a 52G786 from JVC. I've had it 2 years. Love the set, up until yesterday. I only have a roof antennae (no cable) and I've been using it to receive HD TV out of Green Bay for the past 2 years. Direct connect to ATSC jack. Yesterday it stopped working. No channels come in at all. I know the antennae and cable are fine (tested with a smaller TV with ATSC tuner). 
It is possible for these ATSC tuners to just up and die? 
Thanks in advance for any input. Todd

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.

Do I need a digital converter box & antenna to get


It really depends upon your TV. If your TV is newer and has an ATSC tuner in it, then no - you'll just need the antenna. However, if your TV is older and doesn't have an ATSC tuner, you'll need an external tuner, what you're calling digital convertor, and an antenna to get the local channels. Use Google or another search engine to find the specifications for your TV to see if it has an ATSC tuner. Or, connect an antenna to your TV, run the channel scan (off-air antenna mode) to see if you get any local channels. If you don't, you'll need the external tuner.

You might want to talk to JVC as this model had all kinds of issues--missing any color, picture inverted or backwards just to mention a few.

The solution was to connect it to a computer and use a jig from JVC and download two up grades on sd cards and install them manually.

I mention this as the Light engine in the set communicates with the main chassis and you in fact may have a issue with that.

At least make a call to JVC---saw about 40 sets with this model where this cures all sorts of communication issues--the engine if "set" wrong could easily cause this problem.

HD is pretty critical and if a indoor antenna do not expect much or anything for that matter.

The set has a receiver inside that the remote transmits a infrared signal to--if remotes known to be good do not work on set the receiver is bad.

Is jvc av-32d503 digital ready or do I need to buy a converter box for use with an outside antenna system


Looks like you'll need a converter.

Here's some background info:


Analog TVs were made up until 2007.

Digital tuners for over the air signals are called "ATSC tuners".

To tell if your TV has one:

-If the TV was sold as a "HDTV" or "DTV", it's supposed to have an ATSC tuner built in to it. "HD ready TVs" do not have a digital tuner.

-Check the specs in the owners manual or google the make & model of the TV to see if it has an ATSC tuner.

-If your TV's menu has an option for scaning for digital channels, then it has an ATSC tuner. If it dosen't have a way to scan for digital channels, then it doesn't have a digial tuner.

Most DTVs also have a digital QAM tuner that is used in some (but not all) cable systems.

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.

Poor radio reception.I've tried a new aerial mast,no improvement. CD player sounds fine. Any ideas? (Passat Est.2003)


Important! Please give copies to all your VW Technicians C 91--99--07 E 1999 Volkswagen of America, Inc. 1 Subject: Model(s): Group: Number: Date: AM Radio, Poor Reception 1999, 2000 91 99--07 New Golf, New Jetta, Aug. 2, 1999 New Beetle, Passat Condition AM reception is poor. May be caused by: ? An incorrect antenna mast installed for the antenna base equipped with the vehicle ? Poor ground at the antenna base or radio ? Poor battery ground to chassis or engine ? Poor antenna cable connection at Radio ? Corrosion at the antenna coaxial connectors at radio or antenna Service Vehicles are equipped with either a Bosch or a Clarion antenna base mounted on the roof and (for shipping purposes) the appropriate matching mast is located in the luggage compartment. If radio antenna masts are removed from vehicles and stored until vehicles are sold, there is a chance that an incorrect mast can be installed at the time of delivery. Note: Mismatched antenna mast and base will cause poor AM radio reception. The antenna base and mast can be identified visually as follows: (Cont. on Page 2)91-A260 requires gloss finish antenna mast 57mm 49mm Bosch 91-A261 requires matte finish antenna mast 61mm 41mm Clarion 91-A262 Technical Bulletin Important! Please give copies to all your VW Technicians C 91--99--07 E 1999 Volkswagen of America, Inc. 2 Bosch antenna ? Base (although oval) is more circular in shape (approx. 57mm x 49mm). ?

Base is more oval in shape than Bosch (approx. 61mm x 41mm). ? Two screws on underside of base are painted. ? Requires matte finish antenna mast. If antenna mast matches the antenna base correctly: -- Check antenna coaxial cable connections --arrows-- for corrosion and clean if necessary (DO NOT apply stabilant). Passat coaxial cable connection for radio is under the carpet on right side of tunnel near shifter. -- Ensure that coaxial cable is firmly seated in radio (Passat cable connection, see previous step). -- Check ground at the antenna below roof Nut --4-- (torque = 7+1 Nm) must firmly secure antenna to roof).
