LG 42PX4DV - HDMI Audio / PC Audio IN problem

First, you need to identify which box the problem is in. Does the TV work with other inputs? If not, problem in TV. If it does, then the problem is in the Yamaha.
Once you know where the problem is, you can proceed to fixing what's broken.

you should have a digital audio (HDMI) in your volume control options if not install the driver for it depending on operating system and you'll should be fine.

Hi andy838,

I see that you LG LCD HDTV is giving you a No Signal message on the Screen.

see steps Below on finding out what will show video on your LCD HDTV.

* First make sure that the HDMI cable is connected to your Laptop to the HDTV LG.
* On your TV check your remote control and look for the input or Source Button, this will help you set your TV for the HDMI connection.
* Once set, turn your Laptop on and see if the HDTV will provide Video from the Laptop to your HDTV using HDMI.
* I believe that works right, now we have video still we need to set the Audio to work from you Laptop using HDMI to your HDTV.
* On your Laptop lower right side look for your speaker icon, right click on the speaker icon then select Playback Devices.
* Once you've selected Playback Devices you will see a window showing you a list of devices and the first one on the list will be you HDMI connection right click on it and select set as default device this will make your audio work on your HDMI to your TV.
* Once audio to HDMI is set and you want to go back to your Laptop just set the speakers as the default device this will set your speakers have the Audio working again on the Laptop.

I hope that this will help you regarding your concern.

Have a nice day,

You need to connect an audio patch cord between the laptop and the TV. Use the headphone jack on the laptop (3.5 mm M). Check your LG TV manual for the correct audio in on the TV. (Usually it is next to the VGA port if the TV has that PC input.) Computers do not send sound on the HDMI video output.

I hope this helps.

Chances are your desktop doesn't support audio through HDMI. Try to find a spec sheet for the unit you have, an upgrade may be possible

i have the same problem. i think they just get old, i solved the audio problem by taking the cove off the back and disconnecting the speakers, i now just use PC speakers, works grand. i haven't solved the HDMI problem yet..

I don't know for sure, but you may have to go to display properties on your laptop and pick your second monitor.http://www.svideo.com/displayvideo.html.
