Question about JVC HD-52G786 52" Rear Projection HDTV
The first time I lost sound I had turned off the tv & went to bed. Got up in the morning & turned on the tv & no sound. I messed with it all day switching audio jacks etc. to no avail. Finally unplugged everything. I then plugged in the satt. receiver only & gave up. Got up in the morning, turned on the tv & it had sound. Picture is good. 1 week later & still only the satt. receiver hooked up I turned off the tv that was working fine went to bed ...got up in the morning turned on the tv & no sound !!! Left the tv off all day. got up in the morning turned on the tv & it's working fine again !!! Any solutions ?
Replace or have replaced the Audio board in the set----a lot of them fail.

check and see if you have the center channel on in the menu if you do turn it off and also see if you have the internal speakers turned off if so turn them on.

Hi, don`t know if you`ll be able to find this but D9405 a surface mount diode on the main power supply board is a known issue for yours and many other models, it has to be re-soldered not replaced, other joints in area may also need to be "touched up", other than that I had one where connector CN310 was not seated correctly, one side of plug was cocked way up, other than those 2 you may have a bad ballast (board that the lamp is connected to), Be sure that the lamp door is securely closed as they have a switch built into them and if the switch is not closed the set WILL NOT start, hope this helps you out, BMW Rider

Look in the owners manual for the directions on how to remove the lamp. Your model the lamp goes in from the front on the left looking at the TV. There is a thumb screw in the back on the corner holding the left front speaker on. Under the panel there is another thumb screw holding the lamp door on. You will need a Phillips screw driver to remove the lamp. You will most likely find that the lamp is bad. You will either have to order a lamp directly from JVC, a service center or a parts distributor.
