Television and Home Theater

My T.V. is like totally broken! Last year my little sister pushed the power button all the way inside of the T.V. but you could still turn it on with the remote. If need be you could also use a pen and kind of poke the power back on by sticking the pen inside of the T.V. and finding the displaced power button. Well, no worries, right? Wrong! Today my little sister decided to hide the remote and so to turn off the T.V. I had to use the old pen method. Well something went wrong and now its like we can't get cable.

Hi, I just got a new lg 19" monitor and when I plug it into my computer, it says analog out of range. If I play with the pixals, the "out of range" numbers change. Help
