Re: rca model P46920BL
This could be a remote problem, try it while the remote it out of range/no batts if so just replace the remote.
Pull the batteries out of the remote - fixed? Then:
Check the switches, sometimes people clean the set and fluid drips down corrodes the hidden switches and some components near them.
If not that check continuity of the switches
Another thought, is if you have compact floresent lamps
in the room, these can cause some IR interference that
can trigger events on your remote control input.
last, does anyone near you has the RCA TV? mybe other remote is effecting your TV...

Problem with channel skipping has rectified itself. I simply unplugged the set and and started over with remote intructions on signal and channel setting. The tv was also turning itself off and on, this also has ceased. Thanks, hope I don't need you later.
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
