    If there is no audio signal for longer than 10 seconds,the wireless receiver will automatically switch to red.I think that the wireless sub-woofer is not communicating with the wireless receiver .

If the RCA cables are correctly connected you should have an "AUX" input on your DVD player which will allow sound from the TV to the player

Hook up everything right,but can't seem to get suround sound from TV. Went to Bestbuy and brought a Digetal Optical cable and it still dosen't seem to give mr that sound like the home theater sound---help!

On the remote press the surround mode button and set it to Prologic movies or music when you are watching TV to get the rear speakers to work.
Or if you have Digital cable TV with Dolby Digital 5.1 content, make sure you have connected theLG to your TV using HDMI v1.3a. There is an audio return channel on this cable which will stream 5.1 audio signal to the LG system.

This system has a wireless subwoofer that doesn't connect anymore. When the unit is plugged in, it flashes the blue LED four or five times and then goes solid red as though it's turned off. We have been...

I just called LG Electronics 1-800-243-0000 and this is the solution I got from them. Unplug the main unit from the wall, Hold the ON button for 30 seconds. Plug it back in. That should do the trick. They call this procedure a "Hard System Reset". If this doesn't work, call them back and they will repair or replace accordingly.

My LG LHB975 Theather system subwoofer keeps going on n off when playing music flashing blue slowly


Sounds like you having an interference issue. Firstestablish a good connection, then diagnose why the signal is getting lost. You write that the problem occurs whenplaying music, which makes it sounds like everything is fine when playinganything but music.

First establish the connections; press and hold the stop button then press themute button on the remote. Check to make sure all units are operatingwith something other than music. Now to diagnose the issue; what you are using to play themusic most likely is causing an interference that is breaking the wirelesslink. Try something else to produce themusic from, ipod, mp3 player, etc. Don't forget about other things that could cause interference. Microwave ovens, wireless phones, wirelesscomputer router, etc. Hope this helps. Please rate the answer if I was able to help, thanks. -Chris

I have a lhb975 5.1 bdhtib lg wifi with remote sub and rear speakers (blue ray surround sound system), the sub and rear speakers don't work anymore, a few days ago when this started it would come on about...

You've probably found an answer to this already but just in case...

You're most likely going to have to return the unit -- just receiver and subwoofer in my case as the sub was the only speaker not synching up.

Rather than dealing with their useless "Chat" web support, I would HIGHLY recommend calling their support # to get an RMA. Then request they EMAIL the RMA forms to you rather than snail mail. Also, make sure they have your correct name and info in their ridiculously poor customer database. They had my LHB975 serial # associated with some other person's name and address!! It literally took weeks and at least 6 calls to get it straightened out. Never again....if it dies again, it goes straight in the trash.

Digital Optical port to 8-pin din

Optical digital cables can't be magically wired to copper inputs. NO digital signal can be magically connected to an analog interface and work.

Even if you could do what you propose, how would you control volume?

Why don't you just connect the BluRay to the JVC system and let IT handle the audio to the sub and satellites?

Run an optical cable to the JVC TH-C60's Optical In port. Make sure there are no tight bends in the optical cable as that will degrade its ability to transmit a signal.
