Television and Home Theater

I don't know how to program
a daewoo tv memory (eprom)
Model no. DTQ-25S3FC thankyou.

My 51h83 toshiba projection hdtv has red, blue, and green horizontal lines going across my screen. Does anyone know how to correct this problem? The sound is fine and when i tap on my tv the pic comes back! But when i turn the tv off, it goes back to the same problem. i must of tapped on it to much! Because now i can't get it back! Please help me!

I hit the mute button on my Sharp. When I hit mute again to return volume, it didn't come back. I'm connected to a Direct TV box. I was using the Direct TV remote at the time that's programmed to work with the Sharp/Direct TV box. There is a very subtle light "buzzing" sound, very discreet, when mute is off. When mute is on, the sound goes away completely. I've tried unplugging the TV for a while, but, that didn't work.

Any help would be appreciated.
