Question about LG 52LG70 52 in. LCD HDTV

52LG70 sometimes turns off and on periodically

TV is connected to Comcast box via HDMI. Sometimes when channel surfing, tv turns off and back on immediately. Looks like it has to do with signal strength coming from cable box.

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.

Connect the TV to the Comcast box using an HDMI cable, then set input on the TV to HDMI - that's all. You then select channels on the Comcast box , not the TV (although the TV remote can be programmed to change channels on the cable box)>

I am having the exact same issue. It started happening within the first few hours of turning on the XBR9 for the first time. I also have a Motorola box from Comcast. This did not happen with the HD TV that was hooked up previously. Did you return the TV?

HDMI issues with Comcast HD Box


HDMI Has a safety feature that blocks other remotes from changing things. What a Joke I say. There could be a problem with the feature.
You can push up on the "Settings" button on the remote twice to enter the "advanced" settings menu. There might be something in there that needs to be set.
I found out that if I change the cable box output from HDMI to DVI it will work fine but the picture is not as clear.

I believe its a hdmi and communication problem with you box.The only thing you can do is to go back to component video cables until they come up with a fix.

How to Hook up HDMI from Comcast Motarola Cable Box


Connect the HDMI outputs on your various components to the HDMI inputs on your receiver. Connect the HDMI output on the receiver to the input on your TV. HDMI incorporates digital audio, so no need to buy optical audio cables. If your receiver does not have HDMI inputs for all your components, you will need to make a choice. HDMI = Best, component video + optical audio = second best, S-video+ optical audio = third best

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
