Unplug it for 10 secs and plug it back in then wait 10 more seconds and turn it on with the on/off switch. Unplugging makes it reload the firmware, but on/off does not. If that doesn't work try a factory reset. For my Panasonic you do this. Open front door to get at the buttons. Turn TV off. Press and hold the OK button and at the same time press and HOLD the on/off switch for about 3 secs. You should get a self check screen that will last a little while and then the TV will go to the menu screen.

I can't get a signal because this tv don't have cable antenna terminal the tv has rgb terminal. I don't know what to do?


RGB is for a computer screen display signal and has nothing to do with TV display of channels. You must have a Component hook up, it is a yellow cable, a red and a white one. Yellow is video signal, the red and white are sound.

Try relocating the location of your antenna or changing the direction it is pointed. Once this is changed, select PROGRAM CHANNEL from the SETUP menu and set ANT IN to Antenna before selecting Auto to start the programming process.

Do I need some cable box to connect my digital plasma TV to the cable signal? Or can it use the signal without a box?


The cable box will only be needed if you're going to subscribe to receive digital channels. If not, the plasma should be able to receive all the analog channels available with your current subscription.

It sound like you are using a component video connection to the TV, which is of variable specification. Try a different type of video feed from your Comcast box

My plasma screen reads no signal and not available


Well make sure it's on the right source, I have a 50 inch Samsung and when you're on the wrong channel it'll read no signal and you can't do anything. So make sure you have cable hooked up right and make sure it's on the right source or video channel first. I don't know but this might help.

Get HD Signals but it Says Channels not available


you might have to look for "hidden" hd channels.

most cable companies are broadcasting the local stations unencrypted, so you should be able to receive them and sometimes a few other "basic" hd channels like discovery or tnt.

try googling your cable system, city and hd channels to see if someone has posted a list of channels (eg, 88-1 or 102-1)
