I have a cable tv package which was already in place when I moved into my apartment. I operate my tv solely through the cable tv remote control, not the tv remote control. When there is no signal the screen is blue. When I change stations, the number flashes in a large green colour. Now my screen is black and displays the following: 외부입력 which I know means 'line in'. When I try and change channels as per normal nothing happens other than 외부입력시 셕택불가' appearing (which I know means I can't change channels when using line in).

So when I push the 외부입력 button, the channels appear again, but only half of the original selection, a little interference, and assigned completely different numbers.

I have tried every possible combination of button presses but I can't seem to restore the tv to how it originally was (ie, 500 channels, blue backlit, etc).

Can anybody please help this tv junkie?!
