SOURCE: JVC TH-M505 No Sound

It is possible that a fuse has blown in the sub-woofer box. This unit has the entire amplifier built right into the sub-woofer. It also has a number of fuses in it. I have found that over the years fixing these units that if a fuse is blown you will also have more serious problems in the amp circuit. That is usually why the fuse will blow. They sometimes even have a problem in the main head unit with a digital transistor that is a surface mounted transistor that will cause this problem also. This transistor is part of the turn on circuit that signals the sub-woofer to turn on when the head unit is turned on. None of these problems are an easy fix I am sorry to say.

If you have at least a little experience with electronics and the right tools, like a multimeter and soldering equipment, I may be able to help you figure out the problem. But be aware that these are not easy to fix, and you may spend lots of time trying to figure it out just to find out that you will still need to take it in to a service center and in many cases when somebody tries to fix these type of units and have no experience with them they often cause more problems than they have started with.

For starters you can at least check the fuses, but please be sure to unplug the entire unit from the wall outlet before doing anything, there is a big risk of electrical shock.

The bottom of the sub-woofer has 6 screws in it (If I remember right) and those 6 screws must come out, they are rather big and you must use a number 2 phillips head screwdriver. Then after that you must take out all the screws from around the edges of the black metal panel where the speakers plug in to. When those are all out you can pull the amplifier unit right out of the sub-woofer box. Be careful when you pull it out, you will need to unplug a set of wires to get it all the way out, maybe two sets of wires, I am going off of just my memory right now, but if you need more help I will look up the service manual to help you more.

You will find at least one fuse right near the board where the A/C plug goes to and then you will find a few more fuses on the board that is on the right side while looking at the amp block from the same position you pull it out from and this board is plugged into the bottom board and is vertical but the short side is up and down, the long side is going towards the back of the amp and it is running along the metal chassis on that right side.

I hope this helps you, if you need more help just post your questions here.

SOURCE: Cannot TV to play throught JVC TH-C50

i have a jvc th-c60 and only recently started using the system for surround on my tv.

in addition to the surround system, i have a conventional vcr/dvd player. i mention this because i have my cable line routed through the vcr/dvd player - all other connections (audio in/out, etc.) are directly from back of tv to surround unit console. assuming all connections are correct, set the jvc unit to show "VCR" on the unit display AND set your surround option to "All surround". The "all surround" may not the exact term, and not sure what your unit has the same notations, but you should be able to cycle through the surround options and determine when you have sound coming from all speakers. also, on my th-c60 unit, the unit display denotes which speakers are producing sound (or should be producing sound).

and, yes, the college football games sound awesome in surround mode.

SOURCE: NO SOUND From JVC TH-S5 Home cinema system

I know this is an old topic however someone somewhere might benefit from this feedback. I purchased the JVC TH-S5 service manuals from ManualsParadise.com and after metering all the supplies as 'OK', I then focused in on the 'common' lines associated with the two onboard power amps IC's (STK413-400) and found that they were missing a bias supply. This is derived from the onboard 40v Supply 'dropped' down by a 47 ohm resistor R2702 (rated 1/4 watt but advised to make this at least 1/2 watt). The resistor was found to be open circuit i.e. a very high ohmic value. Looking at the circuit diagram again, I would feel that this is going to be a common issue with this unit.

You must have an external cable connection from the DVD audio output to the surround DVD input. As well there should be an output from the surround marked subwoofer. Connect them with the proper cable

Hi, I hve JVC TH G30 and i have connected my DishTV receiver (not HD) to the Aux port of the device. I can get sounds only on the front left and right speakers.. Is there an option to get surround for...


This is a 2-part question. You can get ALL speakers to SIMULATE a surround experience from ANY input, even 2-channel analog.

If there is an optical digital audio output on the Dish TV receiver use THAT and the TH-G30 can decode the surround audio properly.

Read up on surround modes in the manual.

Problem with surround sound on JVC Th-C5 sound system


Not sure how you're hooked up or what model TV you're using. If you mean the TV sound through RCA cables is the source and you're wondering why it's not surround. Well, it's not multichannel. Please fill in some details.

Subwoofer powers on for about 4 seconds and then shutsdown


I don't know if you were able to get the problem fixed, but I had the same sort of problem where it worked and then all of a sudden it stopped working right in the middle of a movie.
I took it to a repair shop and he found that it was the power supply... a $4.00 part.

Hi How connect my wii through JVCTH-D 50 SYSTEM


the reason that you cannot see the wii is because the yellow connection on back of th-d50 is an output not an input. you will need to connect the yellow to your tvs input if possible, and leave the red and 9hite for audion on th-d50. if wires are attached together, then you will need to connect your wii directly to tv, and then use a set of red and white cables to connect from audio outt on tv to audio in on jvc unit.
