SOURCE: Volume and menu does not display
I had this problem on my Aquos (LC-46D62U). It was NOT a hardware problem. I recommend turning off the television. Next unplug the television for 5 to 10 seconds. This resets something for the television. Plug it back in and turn on the television. You should now be able to get your volume and other on-screen displays.
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: volume keeps going up by itself
help the volume on my tv keeps going up and no one is touching it! please help. my parents cannot afford a new tv
SOURCE: MENU SCREEN POPS UP, TV CHANGES CHANNELS, TURNS SOUND DOWN
Yes. Its probably a stuck button on the TV's front panel. Try pushing or wiggling each button on the panel. It could be the channel up/down buttons or volume up/down, menu, etc.
When there is a button that is making slight contact, it keeps the microprocessor busy attending to the command its erroneously receiving from the offending button and may not allow other functions to work when this occurs.
It doesn't matter which button is stuck, any of the symptoms you describe can happen.

SOURCE: volume goes down to 0 and the menu goes on and off.
A bad connection on the small signal board may be the problem! Have a Tech check this connection, it may be to tight due to the heat shrink tube. Have them peel it back to reduce the strain! Should work then!
