The most commom causes are One. There ia a stuck button on the tv itself. The Menu button. The membrane switch or the TACT switch is bad and needs to be replaced. The Main bd can also be bad.

Since it is brand new then should be OK.
Please return it to store and get another TV.

Yes, switch to the video input that you are trying to configure (i.e. video 1-4). Press the menu button on the receiver or the remote and cycle to video settings. There should be a setting that says "video output" or "output" - set that to component. You may also have to configure the Input for that particular setting. For instance, if you have an HD tivo going into component 2 but you want it to be Video 1. Select Video 1, hit the menu button and scroll to video setup. Select video input setup and cycle it to component 2. Next, use the menu to cycle to video setup, select video output, switch to component. This should solve your problem. As a sidenote, you may also have to configure the audio in/out if you're using digital coax or optical. Let me know if this works.

This is due to switch malfunction problem. Dust and corrosions shows these type of problem. Make one general service by technical person. Or if you have keypad lock system in your menu options lock your keypad control. The TV will work.

You have a button stuck either on the set itself or on the remote. Stargazer

There are a number of things that can cause this.

If you have a compact flourescent lamp in the room, this can cause some models of TV sets to go nuts, or not respond to the remote. These compact flourescent lamps use a frequency band that is close to the data carrier freqency of the remote.

Excellent article about compact flourescent lamps interfering with appliance IR remotes:

The other thing that can be wrong is there may be a fault in the keypad assembly on the TV set, or a fault condition with the uPC.
