Whenever I turn the TV on, it automatically starts going through the channels like one of the buttons is stuck. I took the batteries out of the remote to eliminate that possibility, and that didn't help. I then took the TV apart to examine the circuit board that holds the buttons on the front of the TV. I cleaned all the buttons with alcohol, cleaned connections, and cleaned the dust off everything else, just like I was taught in electronics school. That fixed the problem for 24 hours. I turned the TV off for the night, and the next morning, the problem returned. Any suggestions or other possibilities to try would be appreciated, because now I'm stumped!
I have the same issue with my INSIGNIA TV too ... Pravin ... can u please throw more emphasis on to "replace all the Front Panel micro switches - there will not be more than 6-8. Do not waste time identifying the faulty switch" and I will be really needing a step by step instructions !!!

Re: TV changing channels
You seemed to have good knowledge and sense. You did the right thing so far. But, since the problem has reappeared, I suggest that you - at one stroke, replace all the Front Panel micro switches - there will not be more than 6-8. Do not waste time identifying the faulty switc. After all it is only around half a buck a switch! And time is more valuable.

I have had this problem on this same model (F32650) and I discovered that what is happening is that dust and debris are causing the microswitches in the panel to short, therefore the channel starts changing and wont stop or the volume changes etc...
Get some electronic switch cleaner and (with the power off of course!) spray into the crevaces around each button and press each button a few times and then power the unit back on and it should be fine.
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.
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
some tv's default to channel 2 after being unplugged.since it is a older tv ,the buttons on the remote and the tv maybe worn down.on the tv itself try pushing the buttons down a liitle harder. if you have aux or line in/video inputs,scroll down on the channel button to log into a aux channel for the dvd player.as for the remote try buying a cheap universal remote to see if that works.
Yes you can replace the chip, BUT, first try to clean the button contacts. I have to do that to my remotes, phones, and RCA TV (yes I have one too) etc.. around my house. Just needs a good cleaning. Don't forget to unplug the TV.
