Hi I am having a weired problem with my 20 inch Magnavox flat screen TV. The TV is only 2 years old. Till yesterday I didn't have any problem with this TV. All of a sudden it started behaving this way. The TV is automatically going through (counting) the channel when the power chord is plugged in but the standby button is not getting lit. Everytime I unplug the power chord and replug it again the TV screen displays CATV Mono. If I press and hold the TV/AV button then it plays the VHS. If I press and hold the menu button to my cable channel number then the cable works. the volume button works. But the power, channel buttons and remote control doesn't work. basically now I can't use the TV.

Please help.
