I bought this tv not even a month ago and I have a HD cable box ready but cant see the HD channels on my tv. I have the HDMI cable plugged to the tv and cable box but I keep gettin the Unusable signal. I tried unpluging them both for a while still nothing. I have to watch regular channels and can't watch them HD. Any body have any ideas on how to help me?
PLEASE NEED HELP THANKS :)

Go into the menu and change the HDMI Audio settings - the manual will give you a breakdown on this. HDMI is a little glitchy - if you were using red/gree/blue cables before switching to HDMI, you might want to consider going back to them - just an opinion.

if you have a cable box then it is probably the resolution settings in the cable box, what type of cable box do you have

I have the same problem using HDMI cable, I was able to get it working using composite or RCA
cables. I still cant get it working on none of the 3 hdmi inputs

There is an easy way to adapt the cable.
Any good computer shop will have the adaptor.
Take the HDMI cable to them, and tell them you want an adaptor to go to composite signal.
(I know that they're made, many of the graphics cards I use to build computers come with that cable adaptor)
You also might try Best Buy or Radio Shack, but you might not have much luck with them.

Ok. PCB means Printed Circuit Board.
It looks similar to the picture down below. A part must have gone bad on your PC board. So, the RCA shop ordered a replacement PC board to fix the problem. It's an interchangeable part. All newer TV now have PC boards, which each one hold a different function.

Auto channel search finds only one analog and no digital. Cable from cable box hooked directly into tv.
do you have cable, sat. or an antenna? you say a cable box, but where is your signal coming from
