How do I get my SV-4042AFHD tv to play via my home entertainment system? HDMI does nothing!

You can use this firmware too:

SOURCE: LG Home Theater System LHT754 no sound

All you are currently doing is getting sound OUT from the LG HT system. If you want sound from your cable or satellite, you have to run a seperate audio cable into the back of the LG system. If you are running a cable line straight into the TV you need to run an audio cable OUT of the TV so you get sound via the LG system.

First put the orginal ps3 cable onto ps3 then to tv.set tv to see ps3 and go to ps3 setup,now down to display settings,set to hdmi,picture will go off so now switch tv to hdmi input .Next go to sound settings for ps3 and set to hdmi if your amp can work this way ,if not set sound out to optical.
hope this helps.

Hi,
You have connected from PC to TV right???
1.To get the video you have to connect to TV
2.Please take a separate cables for to listen audio and to watch video,
for audio connect cables from DVD Player to Home Theater you can listen the audio
for video please connect the HDMI video to TV Where You can enjoy both.

Hello,
There are two things that I can suggest.
1-Test your optical cables to make sure they a good on a known working source because they are very fragile and break very easily.
2-Try to eliminate the use of optical output from tv to receiver. There may be a problem from the HDMI to optical conversion at the tv. Instead, try running the audio directly from the source to the receiver, and let the tv deal with video input only.
Hope this helps,
Good Luck.
