Sounds like your DVI converter. DVI provides picture only, no sound. If your TV has an digital optical input socket, it's best to connect PS3 to TV using this, then digital stereo sound should be yours..

SOURCE: LG 5010 42" + Xbox360 + DVD RECIEVER/ Surround Sound SET UP HELP!

soulshaun:

I need some clarification before we can proceed. Which audio/video cable did you use to connect the 360 & your home theater receiver & TV/monitor? It makes a difference which you use. The HDMI cable would be the preferred one to use. The fact that the receiver only has 1 HDMI connection limits your options for other digital connections. Respond to this post & I can provide additional info. I have found that when responding to someone's question, I have a tendency to provide too much info on the 1st response.

peace-out

SOURCE: Low volume on LG HDTV

I encountered the same thing using the HDMI interface on my new TWC cable box (Motorola DCX-3200). After a little bit of research, I finally fixed it by changing the digital audio mode in the cable box using this procedure:

1. Be sure the TV is on and connected to the cable box.
2. Using the cable box remote turn power OFF.
3. Immediately press the MENU key on the remote. The USER SETTINGS menu should appear on the TV screen.
4. Select the ADDITIONAL HDMI SETTINGS >>> menu item.
5. The ADDITIONAL HDMI SETTINGS menu will appear.
6. Scroll to the AUDIO OUTPUT item and select this.
7. Change the setting from AUTO to L-PCM.
8. Return to the main page
9. Using the remote, cycle power OFF.
10. When the cable box is turned on again, you should be good to go.

I realize these instructions are specific to the DCX-3200, but there may be a similar setup option available in your cable box as well.

The problem here is that the cable box is by default configured to use Dolby Digital audio, which requires an additional 10dB of headroom to deal with the boosted LFE channel. If the cable operator hasn't taken pains to set the system up correctly (and most haven't, apparently), the digital audio level sent on the HDMI interface will be approximately 11dB down from normal analog line levels on the HDTV channels. Changing to straight linear PCM sets the TV receiver audio level on the HDTV channels to match the levels on the non-HD channels.

The only problem with this fix is that if you intend to feed a Home Theater receiver that uses Dolby Digital processing with the cable box output you will lose the Dolby encoding feature and be forced into straight 2-channel stereo. For a simple installation like mine where I'm just feeding the TV, this fix works fine. If you have a more complex setup that takes advantage of Dolby Digital features (when it's available in program material), you may have to live with the problem.

For a technical reference on why this happens, see http://www.megahz.com/specimages/Dolby/LM100%20Cable%20App%20Note%2011-05.pdf

Hope this is useful.

SOURCE: I have A LG 50PX4D TV the display has gone off

Most likely the tv has a power supply related problem. The most common thing to go out is the circuit board that supply power to the screen. Commonly called a Backlight Inverter Board.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If its under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

Is it ok to play ps3 on plasma tv. I just bought a 50 inch lg plasma and don't want to mess it up. Its a 1080p 600hz


I have 2 50" plasma tvs. One is a Samsung and the other is a LG. I play my PS3 on both and have not had any problems whatsoever. You can also look through the manual and it should also give you some facts about hooking up a console system to it. You should also have different settings for the TV such as standard, sports, game mode, etc... So you can set the tv up on however you wanted to view it. Have fun gaming!

I assume you would like surround sound.

Connect the XBox 360 and PS3 directly to the television.


On the back or side panel of the TV, locate the terminal labeled as "audio variable out." Connect from that terminal to the available audio input on the LG blu-ray system. Then on the system, select the same input you just plugged into. Then toggle through the various audio modes until you get the desired surround sound effect.
