Question about LG 42LC2D 42 in. LCD HDTV

Open Question

I have an LG LCD tv connected to Comcast HD cable box. Everything was working fine one morning and later in the afternoon I get NO SIGNAL for all cable channels...sound is intermittent. The DVD picture is fine and so is the Wii so the tv is still able to produce a picture...it just won't read the cable signal. Comcast tells me the cable box is fine. The tv is set on component 1 which is where it needs to be for cable. Any ideas? I have two young kids...maybe they hit a button somewhere???

    Oh, and I checked all the wires and reset the cable box by unplugging it and plugging it back in.

SOURCE: LG t.v is saying no signal on the screen for the cable box and a dvd player.

if the sky box is not registered with your viewing card, it will not show. if you want to check that the monitor is working plug in a dvd to make sure its not the monitor that is at fault.

SOURCE: 52LG70 sometimes turns off and on periodically

I had the same problem. I changed the 4-3 setting on the motorola cable box. Turn off your cable box and press menu. My 4-3 setting was set to auto. If you turn it off, you lose the 4-3 aspect on most channels. I changed mine to 480p and so far it seems to be working. Worth a shot.

SOURCE: "No signal" sign on TV screen using HDMI selector

it sounds like a refresh issue, double check you selector and make sure it fits the refresh of the tv. i had this once with a sharp where the tv was 120hz and the selector was 60 and it created a no signal and when it did come in it was jumpy. if you have a 120 tv then selector should be the same.

SOURCE: LG LCD HDTV 'NO SIGNAL'

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.

Cheers

I have a Sony Bravia KDL-40EX400. Every morning I have to reboot my cable box to get my cable signal. I get the "Unsupported Signal" message and no picture if I don't. I have seen other posts about this...


All symptoms show that cable box is cause of problem, not sure that its internale circuit problem (signal processing in cable box) or its getting distorted signal from cable company.
TV sounds good because it works fine with blu ray player that is HD signal as well.
Change cable box just to confirm it.
I hope this tv would be under warranty so ask nearest Sony service to update its firmware under warranty cover that might fix the issue.
Thanks.

LC-26DA5U 26 in. HDTV-Ready LCD Television: i connect a hdmi cable 2 my hd cable box - the pic...


The cable box needs to be set to send different signals when using hd tv and standard tv. Usually a good setting would be 720p in hd and 480p in standard. The tv is working fine it is the cable box sending the signal. If you have another hdmi source such as a dvd player you may hook that up to show the tv is working just fine.

You can use either component (Red/Green/Blue video and red/white audio) or HDMI cables to connect the Comcast HD box to your TV. Most times you can get these cables for free at the Comcast front counter.

Have you tried powercycling your box? Checking all the connections making sure they are tight fitting? The guide should always load no matter what.

Connecting HD cable box to DVR too HDTV


When I hooked up my HD cable box using an HDMI cable, I had to go into the cable screen menus and select HDMI output. You may have to do something similar when using an S-video cable. Your DVD recorder doesn't seem to have an HDMI input, so you'll have to use the S-video or (worst case) composite video (red, white, yellow cords). Your cable box may also be scrambling the signal so that you can't record. That may be why you can record by bypassing the cable box.

LG LCD HDTV 'NO SIGNAL'


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
