Question about LG 42LC2D 42 in. LCD HDTV
TV will be working fine, then all of a sudden, no picture and 'no signal' sign comes up. This can last anywhere from a few minutes to all day. Sometimes cable signal comes back, but still can't get digital or analogue signals.
Have had digital antenna installed. all other analogue tvs work as does cable in other room. Also, when this happens, if i try to watch recorded tv, i get a picture, but there is no sound.
To fix the problem, try turning off the TV and unplugging it from the outlet. Once unplugged, push the power button and hold it down for 1 minute. Then turn the TV back on and rescan for channels.
If the problem persists, contact LG customer service immediately as there is a problem with the memory card. The device is unable to retain scanned channels for immediate feedback.
All LG LCD automatically comes with a 1 year manufacturing warranty. You would have to provide proof of purchase to show when it was purchased. Hope this helps. The Guru

I have a 26" LG and this happens to me any time I unhook a cable from the back of the TV, HDMI or not!
It is NOT THE HDMI CABLE!
Make sure your TV has no Power and unhook every single cable from the back of your TV. (press the power button the make sure)
I left my Coax cable hooked up and I did not lose any channel information when the power was off but I did this pretty quick!
Once everything is unhooked from the back of your TV, reattach everything! (I know it sounds stupid but it works for me.)
Once you have attached all the cords again, turn the TV back on and you should have your HDMI again!
I don't know why this happens but I lose my HDMI on both Connections just by removing my Coaxial Cable Connection! TV/Comptuer/VCR all come in fine with Coax/RGB/RCA connections but I lose both HDMI untill I do the process listed above.
I should note that I have had this issue with other TV manufacturers as well, it seems to be an issue with HDMI itself.

I. Turn the TV back on and rescan for channels on input from Comcast Cable using RCA component cables i.e. red, yellow, blue, green, and white
A. Choose 'Components' as imput source
1. Choose 'No' to scan from existing channels
2. Choice of 'Antenna' or 'Cable' shows 'Antenna' but default and will not move to option Cable image
3. Scanning begins with '0' channels stored
4. Batteries in Remote Control seem charged
II. I have Alternate HDMI 1 and 2 Ports open in Monster Wire
A. I note there is a antenna and cable button on the bottom left corner of the back of the television and am controls the remote?
III. The Amplifier is on auxillay and I can hear television channels coming directly from the Comcast Cable Box by changinging the comcast cable Remote Control. All televions in the ouse have a picture.
Conclusion LG 'No Signal" is a problem with the television.

If it still under warranty get intouch with LG-if not looks like (if its definitely not your input signal) theres a problem on the mainboard- if theres a firmware fix for the issue youll have to look into as there are many forums with ppl who have problems like this
