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.

SOURCE: JVC HD-52G786 shuts off

Do you have your TV plugged directly into the wall? You cannot plug into a power strip, it needs its own direct power source. Also, I have heard that there can be electrical problems inside. I have this same model, I love it, picture and sound. I just replaced the bulb for the first time last night. It was a little premature to replace it now but I know what caused it. I bought a new bulb and it works like a gem. If you ever need to change the bulb do it yourself. It takes maybe 2 minutes. The bulb looks like the Flux Copassitor and all you do is remove the door in the back on the side. Unscrew the the 2 screws that hold the bulb in and just pull out. When you put the new one in make sure you do NOT touch the glass on the new lamp. Just slid it in and screw the 2 screws back in and make sure the door is closed and tight. My uncle had a service guy do his and he got raked for 5-$600, The bulb costs about $200. Should last about 5-6 years at a rate of 5-6 hours of TV on time. Hope this helped. If not, sorry, but at least you know how to change the bulb. Good Luck!!!

SOURCE: JVC HD-52G786 Service Mode

Sure. I'm not sure if you can do it without the original remote, though. On my remote, you need to have the tv turned on, then press the sleep timer, then press the display and video status buttons simultaneously. This enters the service mode. Then, you should see an option for self-check (#2 i think). Enter that, then you should see 2 vertical columns of different inputs. From that screen, power the tv off. This resets all the ports on the tv.

SOURCE: 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.

Why isnt my tv volume not working?


make sure you have tried the volume with the remote and the buttons on the set, if the buttons on the set work then their is a problem with the remote. if neither work then the sound circuit is bad in the set.

40 samsung lcd tv problems


remove batteries from remote control and adjust volume to desired level. If the volume stays the same then there is a problem with the remote. If the volume lowers again then the problem is with the TV. the volume button on the TV or on the remote may be malfunctioning. Hopefully it will be on the remote. If it is the remote, take it apart and clean it with damp cloth. after allowing it to dry, re-assemble and try it out.

TV Volume goes up by itself and remote wont work


Hi,

There are 2 reasons that this is happening in respect to the problem commencing after your daughter has cleaned the tv. Either your daughter has sprayed the volume button with cleaner and fluid has got into the the graphite pad under the button and conducting as though the button is being pressed continuously..or she has put too much pressure on the button if it is a metallic plate contact switch.One way to find out is by pressing the down volume button.does it it click ? if it does.try the up volume..If that doesnt click the problem is the metallic plate is dented in making contact hence a new switch. Another cause ive seen is cleaning the remote control with cleaner and fluid has got into the remote and it sends signals to the tv all the time..If the remote control is hidden under a cushion and the problem stops, then the remote control is at fault and needs drying out..Hope this helps :)

Remote, menu button, volume up buttons dont work anymore


You need to open the remote unit and clean the touch pad contacts and the circuit board contact points with pure isopropyl alcohol.

Grease may have worked itself into the remote an has caused those button contacts not to produce the data signals.

Sansui tv/vcr combo is stuck on highest volume.


If you have the remote,have you tried it ?
Have you tried the volume button on the front of the set ?
If neither the remote or the button will work, then you may have a problem with the microprocessor IC (system control). If this is the case, then the set might not be economical to repair.
Perhaps the volume "up" button is stuck ?
