I cant get my tv to get the regular cable
If your TV has a menu button, go into the menu and try setting the input of the TV to the jack that you connected your cable to. Sometimes the TV will not check all the inputs and just does the default one when you do the auto-tune search function to find the active channels. Also, check to see that your wall receptacle is actually hooked into your active cable TV line. You should have a splitter somewhere in the same line that your other TV is using. If not, that jack that you are hooking up your new TV to is probably not active.

Sharp aquos 46d62u has sound, but no picture
We have the same problem with our 32" Aquos. Turn on the TV and after a couple seconds the picture goes out but still have audio. So this solution doesn't permanently fix the problem, but it works instantly to get the picture back. With the TV turned off, tap the side of the set twice with the palm of your hand. Turn the TV back on, and VOILA, you have a picture. I know the last thing you think to do is to hit your TV to fix it, but that is often how my husband tries to fix things...this time it worked!!
TV will not turn on to channel 4 everytime. I have a cable box and need the tv to remain on channel 4.
As long as the tv is not unplugged it should stay on the same channel when turned back on. If you have the tv plugged into the cable box, when the box is shut off it basically unplugs your tv and the tvs memory is reset. The tv should be plugged in to its own outlet or leave the cable box on and turn off the tv. If you turn everything on, cable box and tv, and have a picture, go into the tv menu and auto program the channels, it should only lock in on channel 4 since it will be the only channel the tv will receive.
