Channels keep changing

My TV was working fine but now when I hit the channel up or down it keeps moving and if I hit the volume it keeps going up or down. I changed batteries and even tried a new remote but it is still happening. If you have the answer to this problem please email Thank you.

Re: channels keep changing

Ok, let's try the simplest things first.... unplug the tv from the wall, and remove the batteries from the remote. wait about 5 or 10 minutes. reinstall the batteries and plug the tv back in. try it again. actually since you said you tried another remote, you can skip removing the batteries from the remote. if it still does it, try unplugging the tv overnight. if it still doesn't work right then, you have a processor problem, and need to have it looked at by a service tech.

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

Channel keeps changing

It sounds like a stuck button or switch. What happens when you hit the channel DOWN, does it still keep scrolling down?
Is this with or without the remote?
Have you tried it with the remote and or the TV?

Let me know whether you are changing the channels with the remote or the buttons on the tv and I can try to give you a couple more suggestions.

Keeps changing channels/volume by itself

One or more of the front switches are likely leaky.  They are less than $3 apiece and I just change them all to save future problems.  You might be able to push all of the buttons on the front of the set a few times such as volume up and down and channel up and down and temporarly cure the problem but the switches will likely need to be changed.

Tv wont stop changing channels

ok, Sony had this issue on their early production. The problem you are having is called a leaky switch. The volume down switch on the TV is leaky. To fix this you must replace the switch. This part is called the switch block. Part number 1-473-549-21

Average cost $26
