universal remote control-? I had it on a news channel and when I tried to change it to another channel I couldn't. If I did it manually it just flashed a message saying, "no signal." I accidentally lay on it that night, I thought I might have hit some button to cause it but I worked for hours and I could not fix it.Someone who knows a lot about tv, checked it and said I needed to reprogram it---I've lost my instruction booklet that had the numbers needed to program it, does anyone know what I can do to fix it?
