Question about JVC TH-C50 System

7 Answers

Our DVD/Receiver won't turn on and its not a power cord/pluggin in issue...

Not that it matters I guess, but we have a JVC Th-C50 and it... just won't turn on now ... Not sure what's up, worked fine last night -- red light was on standby, no big, came home from work and it wont turn on. we've tried plugging it into different plugs, we've tried separating the subwoofer and plugging that in ... also nothing. The whole unit seems just dead... and not sure what else to do. We're looking into getting another system probably tomorrow - but my husband wants to try and fix this one... any tips on what it could be? I read one comment on amazon about this unit -- a guy said he had the same problem with it. We think the subwoofer is fine -- but the main unit dvd/receiver doesn't seem to be getting any power. Anyways.... any help/tips you can give is much appreciated.... thank you!

    I too have the same issue on this system. Mine is only 7 months old. Nothing but trouble with this junker! If anyone knows where to find the fuse , please post asap. Thanks

  • bohdawg Dec 04, 2007

    Working fine in the morning and then get home and it won't turn on. Anyone figure out the issue yet on this? Or what your fix was?

    junk sold at visions th-c50 wont turn on 15 monthes old

  • Laura Griffith Jan 25, 2008

    actually, *months later* we have a solution to all this

    Yes, the fuse burns out. Seems to happen whenever its unplugged and then replugged in, or theres even the tiniest of power spikes....

    great quality huh?

    Go to ur local radio shack -- pack of new fuses is only a few bucks and u can pop off the cover and install the new fuse right below where the power cord comes into the dvd player.

    Its a quick fix and lasts until ur next power problem -- but seems to be a manufacturer problem.

    Note -- the fuse currently in there is white...u cant see if its burntout. replace it anyways, with a newer fuse that has a transparant case so u can tell later if its burnt out.

    The other night the right front speaker went out then a few day later no sound at all. the video still works but no sound, The subwoofer (which drives all speakers) is dead. The fan doesn't blow, the power LED won't light. I've checked 3 fuses in the subwoofer, all good. What now>

  • culp1961 May 04, 2008

    We have one too that blows the fuse almost immediately. We think it has to do with the motor for the dvd player. Thats were the problem started. We opened it up and couldnt find anything obvious.

    Any ideas?


  • jon42 Jul 28, 2008

    Thanks, for the info, I checked the fuse in the receiver and replaced it. That was definitely the problem. I was ready to throw it away, it's been that way for months, and repair shops charge you more to fix it, than what its worth. It's working fine

  • helpmyjvc Aug 26, 2008

    Having the same problem. I went out and bought new fuses but once I put them in, plug in unit, the fuses blow immediately. Unit is only 14 months old. I will chuck it before I take it to an authorized dealer. Can anyone offer another suggestion. Always been a jvc fan but this problem is souring me. Thanks everyone!

  • sueabbiss Oct 17, 2008

    We have the same problem. We replaced the fuse, and when we turned the system on, the fuse blew. We got the slow blow kind. What else can we try? We only use our unit to control the volume. We have probably used the DVD player 3 times and the VCR twice. Sounds really strange that it would just stop working.

  • curry07 Nov 28, 2008

    I have a thc40. since new got the run around on repairing or replacing the unit. I checked the fuse w/a meter it checked fine. any other suggestions as to what my problem may be?(no standby light,no power,but have power to both sides of fuse.

  • Anonymous Dec 24, 2008

    I had the same problem, after moving. I replaced that fuse and it works fine now.

    my receiver lights up blue then goes back off changed fuse but it still happens

  • madtownJump Jan 25, 2009

    I also have no power, but the fuse checks out fine. I have a rental DVD stuck inside the unit that I cannot get out and don't particularly want to completely ruin the DVD/Home Theatre center to get it out, but what are my options?

  • jms_glsby Feb 10, 2009

    The unit was working fine then just shut down. Every now and then the stand by light will come on then go off. Seems not to be getting power, tried other plugs and the same thing happens. I will try replacing the fuse and see if that does it.

I had the same power problem with my th-c50. In fact, this is a common problem with this model Home Theater In a Box (HTIB). The issue truly is the fuse. All you have to do is take the cover off and replace the fuse. There are approximately 8 screws total to take the cover off and you can do it with a standard phillips screwdriver. Once the cover is off, the fuse you need to change is underneath and slightly to the right of the power input (if the box in on your lap with the front facing away from you). The stock fuse is a ceramic, white fuse and if you aren't familiar with fuses, it looks like a very small cylinder. The model number is T1AH250V. These numbers mean that it is a 1 amp, 250 volt ceramic fuse, 5 x 20 mm in size. The fuse is held together by four metal posts. Bend the posts back to take the fuse out. Go to Radio Shack or your local hardware store and get a replacement fuse with the specs above. The problem that I had is that none of my local hardware stores had a ceramic fuse with these specs, only glass. I bought the glass fuse anyway (T1AL250V) and it works beautifully. Be sure to buy a "slow blow" fuse instead of a "fast acting" as they are more durable. Insert the fuse into the slot, tighten the clamps, put the cover back on and your done! It doesn't take too long. Hope this helps.

I have a TH-C30. I had the same problem where the unit just stopped working - no standby light and no recognition of power at all. After checking this forum and another, I opened the unit, found the ceramic fuse where the power comes in and went to Radio Shack. They have a T1AL250V fuse pack that is a 1 amp, 250 volt, 5 X 20 mm SLOW BLOW glass fuse which is a better fuse for this common problem. Their RS number is 270-1063 and a pack of 4 costs about $3. Put new fuse in and the problem was solved.

The repair took minutes - 3 screws on the back and two screws on each side. Lift the cover from the back (it is slip-hinged on the front) and replace the ceramic fuse. It slips out with a little help and the new one snaps in place.

One thing you can try, that will probably fix this bug for good: Install a "slow-blow" fuse instead of the standard one. The "slow-blow" fuses are made with a little piece of fabric, (of some sort, probably asbestos), stuck into the center of a coil of wire that makes up the fuse. the purpose being; the fabric prevents the fuse from overheating 'instantly', instead, it takes it a couple of seconds to blow at the time of an "over-draw" or "in-rush" of current. therefore the fuse won't be as susceptable to blowing out from a mere voltage spike. Just be sure to get a slow-blow fuse that's of the same, (or within 10 - 20%), value of the original fast-blow fuse, (e.g. fast-blow fuse = 10A @ 250VAC, then slow-blow fuse should = 10A - 12A @ 250VAC). I hope this helps!

I have the TH-C50 and my unit would not start. I did what others advised (above) and installed the new fuse and now it's working perfectly.

Posted on May 16, 2009

I removed the cover from the receiver and check the fuse with a meter. It check fine. Reassembeled the unit, plugged it in, powered the unit and ALL IS FINE. I don't know if the fuse had worked itself loose (don't really think so) or just lucky.

You could pull the cover off and check the fuse (Make sure it is unplugged first). If it has no indicators on it is likely in the input side of the power supply (Fuse, transformer).

I have a jvc seteup but reciever is there a way i can get a adapter to plug sub woofer with power amp into a a yamaha reciever?the plug that goes from sub woofer also powers other speakers, cable...

Here's a manual.

That cable not only carries audio but it also powers the sub and other channel amplifers. Even if we could supply the pin-outs for the channels I'm not sure what we could do to provide subwoofer power. We're talking about a major rework.

This is a highly proprietary design, meaning it's really not very adaptable to normal spec audio equipment.

There's a flat-fee repair service for the receiver ($99.95, free return shipping):

Maybe they could fix your receiver.

You COULD try to reach the manufacturer for other options.

No sound. The system cord and/or speaker cord is not connected. Check the connection.

The audio cord is not connected to AUDIO IN (VCR)

and/or DIGITAL IN (DBS) correctly.

Connect the cord correctly. (A pg. 13)

An incorrect source has been selected. Select the correct source. (Apg. 17)

The decode mode is not set correctly. Select the proper decode mode. (A pg. 35)

Do you think the powered subwoofer itself might have a power problem? Check its cord.

Not getting any power to the DVD player at all. JVC DVD digital theater system th-c50.

Probably a blown fuse. If you have a warranty or can return it do that, if not unplug it, open it up and there should be a 250 volt glass type fuse. pull it out and make sure it is blown. If it is replace it at radio shack. If it isnt check for loose wires around the power cable and the transformer.

My system doesn't work when i'm watching t.v.? It only works while playing dvd's..

"Doesn't work". Do you mean no TV audio at the TV? No TV audio from the receiver? No Video? Both?

MOST IMPORTANT: Is this a new setup or did the problem appear after working for awhile?

I'm going to guess it's a new installation with no audio while watching TV.

Generally, most TV watching originates with a cable box. There will probably be some sort of analog or digital audio output on the cable box. Connect it to the Aux In or Optical Digital In on the receiver as applicable. Select the appropriate input when watching TV.

The video from the cable box will depend on the box, too, but it appears this unit will only accept Composite or S-Video In. If your cable box has a higher quality connection (Component or HDMI), I'd run it directly to the TV for the best video but still use the digital audio feed to the JVC. Let the specialized parts of the chain deal with their specialties - audio or video.

Of course, if your TV has only one HDMI, you will have to choose which source uses it. HDTV would get my vote for it as it needs the best conenction for maximum enjoyment. If the TV has Component (3-wire) Video inputs, I'd use that from the receiver for DVD viewing. I have both myself and see no difference with DVD video between HDMI and component video.

If you lack the manual that speaks to all of this, go to, register and download it for free. It’s a combination JVC TH-C40 C50 and C60 manual.

JVC 8 pin pinout - speaker cable

Looking at the connector, there are 3 rows of pins.
Starting with the first row closest to the alignment mark:
[Power On],[Center Speaker],[Sub Woofer]
[Surround Right],[Speaker Ground],[Surround Left]

If you are trying to connect two JVC units, you will need an 8-pin cable that has the SAME pins connected on each side. You will need to test this using a multimeter set to ohms or 'connectivity'.
There are other 8-pin cables out there like the one for apple networking, but they use a crossover pinout where pin 1 on one end = pin 3 on the other end. This is bad. JVC needs pin 1 to = pin 1.

This is a standard connector/pinout setup that JVC uses, so connecting a TH-C3 to a TH-C50 works fine. There is a bunch of intermixing that you can get away with. The only thing to keep an eye on is the power in watts that one unit sends and the other recieves. Worst case is that the speakers are quiter than expected or that you can turn the volume up so high that it can damage the speakers. In all cases, you should get desired volume somewhere on the dial.

If you are trying to wire the speaker set custom, then you will need to take note that an '8-pin' connector is actually a 9-wire connector. Along with the above pinout, you will need to add Case Ground, which is the metal circle that surrounds the pins. To make the speakers turn on, you will need to apply 12v to the Power On pin and ground the 12v source to the Case Ground outer ring.
The system takes 3 to 4 seconds to fully turn on after this connection is made. Speakers should be wired using the center pin for speaker ground and each other pin respectful to each speaker.
