Television and Home Theater

I have a RCA P52926 Projection Big Scree that is only 3 years old. It will not adjust volume, turn on or off, nothing, with either the factory remote, or my Direct TV Remote. I believe it has something to do with the IR reciever within the television. I consider myself to be proficient enough to possibly fix the problem, or can I? Lookining for answers

Hi, there. New to this so please forgive any faux pas ! I turned on my tv this morning and instead of the brightly coloured tweenies, i have a sepia coloured (brown) screen with fine brown lines on. I can hear fizz, bella, milo and jake ok, as the sound is perfect. I just can't see their smiling faces. Can anyone help? What can cause this loss of picture? I just want some general advice before i decide to do away with my trusty friend and upgrade to his younger smarter brother LCD :) thanks for reading, your comments will be welcomed.
