You must use HDMI 1 port when conected to a PC (to have a picture). Also set the audio in to HDMI not to PC. Look at SOUND/ADVANCED AUDIO. You can use separate analog cable also... Please just read the F manual

I have an LG flat screen no picture or sound

As your TV is three years old, I would suggest you contact your LG dealer to arrange an engineer to call to do a software upgrade on the it. The current software will be out of date & if you are connected via the HDMI connector then this can give audio/video problems.

Use of AV2 input sound socketsto play ipod

The sound is muted unless a video signal is detected on this TV. The only work around would be to connect the camcorder or some other active video to tha input but using the IPOD for the audio.

Green light is on ...white noise sound but no picture

This TV finds the connected input sources
automatically for AV1, AV2 and Component 1-
2. It is presumed that RGB and HDMI/DVI
sources are connected.

Check your setup to see if the audio is turn off but if you have a clear picture you should have sound.

Time to call a TV Tech if you are not going to repair the unit.

HDMI, picture but no sound

Check the menus for both the DVD and TV to be sure that the audio is being sent thru the HDMI cable. Some sets and DVDs will separate the audio from the video be default unless told to send it down the HDMI. Update this if that does not resolve the problem and post the make and model of all gear in the chain.

AV1 / AV2 Connections don't work

No picture or dark picture
Check R516 (56Kohms, 0.5w) or R517 (27Kohms, 0.25w) for high
Will not come out of standby, no picture
If at power on voltage on pin 37 of the micro drops low then reverts to 5v suspect memory chip ICA07 (Toshiba 23319016)
No picture No sound
Faulty IC TDA6107q on crt board
No picture on e-e, I.F output ok
This was due to switching chip IC3901 (M51292FP) on the scart panel

LG 42PX4DV - HDMI Audio / PC Audio IN problem

I found the fix. Had the same problem.
I right clicked on the sound speaker icon in the bottom right of Windows 7.
Chose Playback Devices.
Once this window opens, then make sure you are on the Playback tab.
Scroll down until you see the HDMI Device. (Mine was hidden at the bottom of the list.)
Then choose "set as default".
The sound will begin playing on the TV with only the HDMI need for an extra audio cable.
