JVC TH-L1 sound

I just purchased this system and no matter what different combinations that I've tried, I cannot get any sounds out of the speakers and subwoofer. I connected the cable box in video 1, the HD DVD player in Video 2, and the TV in the monitor output, all using HDMI cables.

What am I doing wrong, or did I purchase a diffective product?

Re: JVC TH-L1 sound

Almost the same problem. HDMI connections good, sound and video through monitor (LCD TV) , but no sound from the JVC unit speakers.

How to get sound to tv from JVC TH-M606 without sub woofer.Also trying to put in progressive mode without remote

  • If I understand your question correctly you want to listen your TV on your Stereo system thru your receiver,JVC TH-M606 ** you need to connect "Audio Output " RCA jacks or "Optic cable output" of your TV
** to "AUX input " or "TV" OR "Any input" of your receiver ( except Phone ) or "Optic Cable input"
** than just switch to respective mode on
JVC TH-M606 RECEIVER corresponding your RCA or Optic connection...
There you go..Your TV sound is on the
JVC TH-M606 Receiver..By this means whatever you watch on the TV (tuner, satellite , Xbox ) ,it's sound will come thru your stereo..

  • If you want to listen your receiver thru your TV, sorry but it is not a preferable attempt since TV sound system is not a HI-FI quality compare to your nice Receiver..if you really want to do it,try to do the connections given above in reverse..
  • And,best of my knowledge I am afraid you can not put in progressive mode without remote

  • Hope this helps!

I've had my JVC TH-L1 Theater System for about 2 years now. I recently rearranged my theater setup in my living room and after reconnecting my system the receiver will power up but not work. I have...

The fact that it stopped working after you tampered with it implies human error in reconnecting.

I'd advise you to carefully go over every thing you touched and crack the manual for settings.

Treat it like you just opened the box for the first time.

Keep the volume at a medium level until you figure it out. One misplaced control like a Mute or Tape Monitor, when flipped, could blow your speakers if the volume is set too high. If you can't hear a source at 1/3 volume it ain't there.

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.

Th-l1 no back lit screen

Although not fully familiar with your unit, many receivers have a small lamp behind the display panel. Sometimes they burn. It is not to easy to replace them bya DIY. If the unit works fine otherwise, it could be just that. lots of other units use Fluorescent type displays, and if they go bad, causes are more complex.
Good luck.

Connecting an Ipod to JVC TH-M45 System

you can hook up ipod 2 different ways. the one i will use will be with a 3.5 to 3.5 mini plug connection(on both sides of cable it has i.e. head phone jack connection) and then set unit to aux in and that will give you sound from ipod. another way is with red and white audio cables to 3.5 mini plug connection. connect red and white to audio in on back of unit,and then set unit to that 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 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.
