LG 42LC7D TV does not want to chg channels after 5 min of use

My LG 42LC7D usually "locks" into a volume down command. You can force the volume up by pressing and holding the volume up on the set but when you release this button it immediately steps back down in volume until it it is back to zero. When in this "locked into command" mode it is very hard to get it to do anything else. It will , for instance, completely ignore all inputs from the remote control. I have been able to force it into a different "loop". I have been able to get it to change to doing a channel up command which again it "locks" into and displays ascending channel numbers at the top left of the screen. I have also been able to force it to display the menu and here it "locks" into a scroll up command. It's driving me crazy! It is such a richly featured set and the surround sound from the TWO SPEAKERS is amazingly good. Yes, it did work beautifully for the first 24 hours. Can't LG phone the people in China who no doubt designed and built the motherboard and get some help??? My LG 42LC7D usually "locks" into a volume down command.

I have the same exactly the same problem with my LG 52lLB5D. Support told me there might be something wrong with the remote auxiliary conector in the back panel. Allthough I have not replaced the main board yet, it looks like this will be the only solution... bummer.

I have a toshshiba flat panel and I have an unknown timing problem just on one channel on antenna tv. All the other channels work. I was watching channel 9 and it just stopped. I did a channel scan and picked up all the channels again but it still will not work. I made no changes to the tv.
