The micro buttons on the tv are causing the problem. Mine kept going up in the channels like you are holding the button down. I took the button board and clipped to prongs on the micro switch to the channel up button. It has three prongs on one side and two on the other that you clip.I use the remote all the time any way and it will not affect that.
my television keeps scanning from channel 4 to channel 37 and the volume keeps going up loud and lowering by its self coule you tell me what could be wrong the television is only 1 year old thank mrs yardley
Try holding the channel up and volume down buttons together on the front of the set until it cuts off. When you turn it back on it should be normal mode. If channel up and volume down doesn't work try channel down and volume up. Thanks
I did not get who the manufacture was of the tv but you may want to see if one or more of
the menue buttons are stuck down on the tv's front panel. This has been a common cause of
problems with Mitsubishi and Sony tv's. It could also cause volume to go up by it's self, no menue
functions, no power up and or no remote control functions to work.
Hope this helps,
i would honestly suggest if you still have the receipt return it back. dont forget your rating thanks.
This is a very common problem for RCA TV. I have one as well. or go to www.tv.rca.com/ there are free manual there
I had the exact same problem with the channel/volume autoshifting. I found a electronic firm that would rebuilt the board for $185.00 plus shipping-----screw that. I cut the plastic hold down nubs on the channel/volume buttons itself and disassembled the contact. Inside the button was a copper metal disc showing arc tracks and "carbon scoring" on the underside. I just removed the button guts and now use the remote for channel and volume adjustments. So far the power button still works for me. I may try buffing and cleaning the disc and contacts later, but what the hey, I'd rather surf with the remote from the couch.
This TV actually has bad buttons I've seen many of them, usually those switches never go bad but on this tv they do. The easiest thing to do is remove them, and use the remote, who uses those buttons anyway. You can slide out the circuit board and you will see the small switches in front if you can solder just remove remove them if not you can cut them out just be careful none of the pins remaining in the board are touching one another.
