Question about JVC TH-C4 System

1 Answer

QUIT WORKING Hello, I was listening to Metallica volume 60 cranked and it suddenly stopped. This has happened many times before but it alway's reset itself by turning off and then on again. Not this time. I took it apart found three fuses all of which were good. How can I check with a multi-meter? Would it be the power supply? If I can't find a solution here, I would be willing to pay for directions for troubleshooting myself if anyone can direct me to a site that does that sort of thing. Perhaps a scope will be needed which I don't have.

    I had the same problem. My power will ot turn on at all unlike before I could let it sit for a minute then plug it back in. I was told by a authorized JVC sevice center today that this is about a 2 out of 10 problem with all of these subwooofer boxes circuit chips which are very expensive (@$100 a piece) often two or so are bad in the unit. This stops the DVD player and anything else from powereing up. It is due to playing the system at high volumes, although it is intended for this and it does have internal fuses, the circuit chips still burn out. Most people do not replace pay the bill for these repairs as a new system costs just a bit more than the bill. Next time I buy it will be Panasonic. I was told they have little problems such as this and in the rare event they do, repair parts are affordable.

I have repaired many of these units in the past but it is not a easy unit to walk somebody thru unless they are a experienced Technician. (Not recommended for Amateur in Electronics). Does sub power up (green led) then shut off right away?? when Dvd is turned from off to On?? Do you hear any relays clicking when dvd is turned from off to on??. If you do not hear relays it is possible transformers internal non resetable thermal fuse may have opened.

Over time the TV volume and the SurroundBar volume get out of sync and we keep having to manually adjust the SurroundBar volume to match them up. We are currently using the DirectTV remote to control

Unfortunately, the system does not work well around other wireless devices. When watching Blu-rays and listening to music, the system works fine, but when I play my Wii or Xbox 360 the subwoofer loses its connection to the bar and stops working. Sometimes I can play for up to an hour without the sub going out of sync, but it always ends up happening. Many times and several times in a row it would immediately go after sync right after I fixed the problem. Polk lists the wireless sub as a feature but it's actually the worst part of the package for anyone with other wireless devices in the same room.

Check the online link to the PDF for more information about sync instructions.

No Visual; Only Audio

No real specific suggestion but it's likely serious. Very likely in the hi-voltage section and quite possibly the flyback transformer; too expensive to bother with if so.

My philips gogear wont turn on

Disconnect the GoGear from the computer
Reset it first (pinhole in back - safety pins work best), even if nothing happens - just to be on the safe side
Nothing will happen still, but we are OK
Make sure the power is off, and hold in the volume + button, reconnect the GoGear to the computer while holding in the volume + button, and continue holding volume + until a window pops us saying Found New Hardware Wizard
Go through the Found New Hardware Wizard, and the GoGear should be working again - the player will be revived

Write me back if this fails to resolve the problem.

The songs that are skipping are most likely corrupt or have been encoded incorrectly.

Delete them and that should solve it.

Best of Luck.
