SOURCE: LG 42LC2D-EC NO SOUND ON HDMI

your setting for source of the audio is probably defaulted back to original setting in receiver. reassign audio input and problem may go away. it sounds like its not in the tv. i assume you have a receiver and are not trying to listen with speakers in tv. is this correct? if you are not using an amplifier, you may need to go to the tv menu to make sure the audio source is selected as the hdmi input. should take a bit to read thru the manual, but it ought to show you how to accomplish the correct settings.
let me know if it does not.
good luck

SOURCE: LG 37LG30 HDMI no sound problem

This is more probably a software fault within the TV. They need instructions for HDMI inputs & a no sound is a related fault. I would get in touch with your dealer to arrange the TV to be updated to cure this problem. Hope this helps.

SOURCE: no signal from ps3 to lg tv via hdmi

if this is the first time you've hooked it up via HDMI then you have to go back to the old cables first. Hook those up to the old TV or the new one, then go to settings and switch to HDMI. It will give you 30 seconds to change the plugs again so you can view the HDMI. Then select ok. Hope this helps

Just bought a 55" Lg Led tv and i hook up hdmi from cable box to tv hdmi 1 and hdmi from my blue ray player to the tv hdmi 2, ok then i turn the input on both now hdmi 2 work but hdmi 1 has no signal why...


try connecting your blue ray player to HDMI 1.
A) If it works there, then you know the port on the TV is OK & the problem is with either your HDMI cable or your cable box.
B)If it still doesn't work then you may have a problem with the port on your MAIN PCB. if it's a new TV your warranty will cover that as long as the input connector is not physically broken.

Why does my LG tv seems like it need to warm up before it will accept HDMI signal?


Sounds like a capacitor fault. They can be intermittent when cold, but will work okay when warm. Eventually though they will fail.

This is your advance notice to get the set either repaired by the manufacturer or a local TV shop.

42LG50, black is not really black


The most common culprit to signal noise is poor quality or defective cables that may have cracks. I would check the HDMI cable. Do you have any other devices with an HDMI output like a PlayStation 3? If the image is fine using it, your HDMI ports on the TV are fine and so would the cable. It could be the BluRay player itself. Since this is a LCD TV that uses a backlight, your blacks aren't as black as you may want. The TV may allow you to drop the level of the backlight so check the onscreen menu for options.
