There is a button under the bottom edge of the screen (with the controls) that has the options "Normal" and "CATV" - press this and it should solve your problem.

this is the same type of problem happening with other rca models and I know it is the EPROM CHIP but why this is failing is either because of design flaw , dirty enviroment that they were made in , to much voltage or current to the chip or too much of a draw from the chip causing it to fail . Or even a random frequency from the IR sensor or its circut I'm still investigating and testing.
leave the tv unplugged for at least 3 weeks durring this time resolder any solder that don't look good , I did this and it lasted for about 6 months(always plugged in to the wall) before it started doing it again. model # 27v412t

SOURCE: not getting all cable channels?
Please post the model number of your TV. You have to get to the menu to reprogram the TV channels for cable vs on air. Sometimes pushing two buttons at the same time on the TV itself will get you into the menu mode. If you use Google and search for your modeel number and "manual" you might get some help there.

You gotta have a way to get signal to the tv . If you don't want a outside antenna use rabbit ears .After you hook them up hide them behind the tv then do a channel scan. If you don't pick up all the stations set them on top and scan again or get satillite or cable hd boxes.

You need to replace the microprocessor. GoodLuck there is 52 pins to unsolder and resolder a new one. The price for the chip may bee about $35
