might be able to use the cable co remote and autosearch thru the codes, but its too hard to explain, the cable tech should have ran that procedure. unfortunately, rca has 50 million models. it is common to have a tv and yes rca for sure, to not take the codes. sometimes the tv is too new for the cable company remotes to work. i am leaning toward the tv too new theory. give it six months and i bet there will be a new remote version.

SOURCE: RCA R301F1 remote problems
If you have tried 5 remotes I would have to say that the set has a problem in the remote circuit. You will need a tech to look at it and repair it. Let me know how this works out for you.'

This model has issues with a small micro fuse that will blow for no particular reason. Poor design most likely. This fuse is a solder on type and is very tricky. Have a shop check it for you before you trash it. Should not be an expensive repair. Thanks for using fixya.

The back lights inverter is working because you can see the "Unusable Signal' on the screen, if the inverter is dead, yoo will see nothing on the screen at all.
If the T-CON (LCD controller) is dead, you will see just gray glowing screen with no pictures or text.
You may have problem with video processor in the main logic board (tuner, audio, source selector).
Parts for your TV:
This is going to be difficult repair since you do have a way to try out the replacement board to be sure that is the problem. RCA service person has that advantage of parts in stock to try out.
I estimate the board from Jimmy to be about $150, from RCA will be twice as much, plus labor.
