I've rebooted both TV and PC.,

did you use the audio in cable which is in your TV cause HDMI works video interface not a audio

Try a new HDMI cable.

Hi raposo69 ,

I see that you are having an error check signal cable.

Have you tried selecting the correct Input for the LG LCD monitor?

make sure that the Correct Input is selected properly to be able to detect the signal from the HDMI cable that you are using.

The audio will not confuse the video on an HDMI Video will be detected as long as the Input on the LCD monitor is selected.

Audio on the HDMI will only work if the HDMI driver is provided like on a desktop computer you will need to get the driver for the HDMI for Audio and video to come out using an HDMI cable but never will audio conflict to the HDMI video output.

I hope this hepls.

Have a nice day,

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 must connect up the TV to the SKY box, via Audio Visual cables too, in order to watch, recorded programs. You need to hook, up, Component, HDMI, or Composite, You select it by an EXTERNAL channel.
Connect the cable running from the wall into the "In" port on the Sky Box HD receiver. This cable brings in the signal to your receiver. Make sure the cable is securely fastened to the receiver, otherwise you might experience image and audio issues.
Attach an HDMI cable into the HDMI port on the Sky Box HDTV receiver. The HDMI is a single cable that provides both HD audio and video signals.
Plug the other end of the HDMI cable into an available HDMI port on the HDTV.
Power on the HDTV and the Sky Box HDTV receiver. Press the "HDMI" button on the TV's remote control. This will display the cable contents of the HD receiver onto the television.

What other device are you connecting to your tv and how are you connecting it?

If you connect via a single HDMI cable that may be causing your audio problem. Some Tv and STB have handshacking issues which can knock out audio and/or video. The only solution would be to replace the HDMI cable or switch to composite cables.

Good luck!

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.

bad hdmi cable common problem

It's the other way around.

Hook up the Cable box to the Amp; and the blu-ray to the amp, then connect amp to LCD.

you want to use the best available options for audio:
HDMI > Digital Optical > Digital Coax > standard RCA

And the similar for video:
HDMI > Component > SVideo > RCA cables

I would connect Blu-Ray via HDMI to Amp, and Cable box via HDMI to Amp. If your cable box does NOT support HDMI, but you have an HD package, ask your cable company for an upgraded box.

there are 2 types of flicker, one is the lamps that drive the display and the second is the sync signal of the video.
I assume the video sync is the flicker you see,
I would try connecting a different way to make sure it is not the tv,
connect using the aux /rca connectors to cable box.
and or connect using the cable direct bypassing the cable box.
I have seen several complaints about the hdmi cable signal being incorrect in some way,
this is the same issue that the svideo connector had in its early adoption signal was too hot or too low.
another thing to watch out for is the low light sensor on the front of tv if it gets an incorrect reading it can flicker the back light though it should be slow in doing so.
some times the flicker you see is not flicker but ac running through the sides of the picture from an ungrounded cable source.
how does it perform if you play a dvd player , with and without the cable box connected.
