I just recieved a 27" TruFlat from a relative last night. I hooked it up last night and it ran fine. This morning, it came on by itself and was channel searching. I couldn't stop it or go into the menu. I unplugged the TV, and plugged it back in, and it would turn on and go back into channel search mode. I left it unplugged for a while and plugged it back in, this time it turns off when I hit any buttons on the TV set. The remote stop working too. Should I get this repaired or call it quits?
Sounds like a power fault, prob just weak capacitors if you can change them it would not cost a lot to replace them, when you change channel it draws more power and if its at its limit it will turn off as the capacitors cannot take it. few £'s or $s to get the replacement capacitors, you will probably see the blown capacitors on the power board as the will not have flat tops they will be rounded, change them same for same i.e 16v 330 for same 105c type would be best. it will say this on the capacitor.

Hey this same thing happened to me not too long ago and you just have to buy a Universal remote and program it (it should come with the codes to program it to your TV) I think the code is 704 or 702 for RCA... Anywho after that then you can turn your tv back on wit the remote and push menu and Preferences and then FPA off. Its just a parental control block so your kids cant touch the tv buttons and mess with your settings.
SOURCE: 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
SOURCE: rca 32v432t tv plays,turnsoff,turnson, and stays in autochannel search mode
your going to need to do a resolder of dry looking solder jobs and or poor solder jobs
this could also be your front control board , try disconnecting it and see if the tv stays on
it is possible that the sensor has gone bad or the crystal needs to be replace or worse the EEPROM
my rca 27 in was doing the same thing , i resoldered the board and it worked great for 7 months
so do a resolder of all suspicious solder and heated components
then let me know what happens
also what is your model # for your rca tv ?
also one of rca's kits for repair is some solder and paste , so that should tell you something in its self about rca repairs ( the solder with the paste is supposed to make it handel heat better )
please give a fixya rating so that if you need more help in your tv , I can continue to help you further , thanks
