Channels just automatically started changing themselves and will not quit

We can get to the menu and the guide but because of the continous changing of the channels we cannot get it to stop on anything to make the changes such as Language,etc. We have looked through the other problems and could not find one such as ours. We do have the TV unplugged and are awaiting info hopefully from you to help us. Thanks Tadpole

Re: Channels just automatically started changing...

I have seen this befor, 1st. take batteries out of remote to make sure that no buttons on the remote is causing this problem. If the problem presists then the fault is the buttons on the front of the tv.power,vol,ch, etc. if one is bad I replace them all. if you can remove the front board, ( it usually clips in and out hard, try not to break the clips) if the wire/cable dissconnects you can take it somewhere that sells switches. the originals are $5.00 to $10.00 each, price adds up fast. or replace one at a time & take your chance. good luck.

Channels and inputs change by themselves

sometimes unplugging it from the wall for a few minutes or even overnight can fix weird issues like this.

also, there is a small chance that a new channel scan thru the menu system might refresh the channel memory and clear it up.

this series of TV's are prone to a lot of problems tho, so it will likely soon be time to start shopping around.

Why does my RCA TV cycle through channels on its own?

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
