Television and Home Theater

NEED HELP!!!

I have a 52 inch Samsung Projection TV (Model NCN529W).  It is about 3 years old.  I get no picture (nothing on the screen) or sound.  When turn on the power, I hear the turn on sound with a red LED light on the power button.  I took the back cover and check the fuse and it seems okay.  Any suggestions or recommendation how to fix the problem?  Any comments or suggestions will be greatly appreciated.  Thanks

I have an RCA F35665 that will only come one between 12:00AM and 4:00AM. after it is on a few minutes it will start schrolling down thru the channels stopping sometimes, and the sound increases. When it stops I can control the channels until it starts scrolling again. Any help would be appreciated. mjlayton
