TV turns on & off by itself. Channels also change by themselves.
My TV seems to be possessed by something. It turns on and off by itself. Once it's on, it won't be long before the channels start changing. At first I thought I was sitting on the remote. It wasn't that. I took the batteries out just in case it was the culprit. It's an RCA 36" F36668 TV. Can anyone explain?

Make sure your remote is totally away from the set.
Make sure the buttons on the set are not sticky
If both of those are ok, it's your E-Prom in the set. RCA's are notorious for this, not a major repair, maybe $75-100. The 8 leg e-rom is only about $6.00

Be sure your remote hasn't got a button stuck down which is changing channels. If not, take the batteries out of the remote. If this stops the channel changing there is probably some conductve material stuck across the circuit board
inside the remote. If this is the case you have to check inside the remote by openning it up.
I have seen problems like this caused by spilled liquid. Bad switches can definitely do this as well, and can be, themselves, filled with dried sugary goo or corrosion. I wish you could still download schematics for these, but TTE (RCA's new horrible Chinese owners) shut this off. Now they want $40 a pop for schematics, making repair unfeasable for many units. If the switches are a standard type, you can get them many places. You can also clean them by removing them from the board and washing them in isopropyl alcohol, with limited success. Parts for older RCA/GE sets are still available. Most good distributors will research and order these for you gladly, so you can merely call and tell them what you want. The new Chinese RCA/GE/Proscan units are essentially disposable, so don't get a new one of this brand.
Unplug the TV for 4 hours or more. This is called a 'Hard Reset'. Then plug it back in, turn it on and let the TV do it's thing. It will set itself up. Just follow the TV setup prompts. Guide Plus is a feature on the TV. Much like a TV guide showing all channels, shows, description of shows, times, etc..
yes and this is a common problem! First lets check out the obvious/ when theis fault starts to happen take out the batteries out of the remote control. If the problem stops then you need a new remote. If the proplem persist the remote sensor assy is bad in the tv set. Ive never heard a cable box causeing a motherboard to act up?? Wait arent mother boards in computers?? lol. believe me you need to tell the tv msn to replace the rmote sensor. Now in an extremly rare cases the microprocessor was causing the problem BUT highly unlikly. Good Luck
Have you checked to see if any of the front panel buttons are depressed and stuck??? this is a big problem these days?? I have also found the infared remote sensor to be bad on some sets that do crazy things all by them selfs.. A funny storry once i had was a customer called me after her mother called some goast finders as her maggy projection set would go on all by itself andf the channels would change and the volume would go up and down all by its self. funny thing I had a set just like thast in the shop at the time with the same problem and I scoped out the output pulse from the infared reciver on the set and that was putting out noise on the data line and caused the set to eratacly do all sorts of weird stuff. get the point?? its a stck button or the remote sensor is bad.
