TV (RCA model F32705) stuck on one channel

My TV is stuck on ABC. I have no remote for my TV. It broke and i felt I did not need it anymore. Anyway, I change the channel the old fashioned way, I get up and use the button on the tv. As I said earlier my tv is stuck on abc (channel 3 i think). When I change the channel using the buttons on the tv the channel number changes but the tv stays tuned into abc. Does not matter if I use the up or down channel button the result is the same. I have unplugged the tv and disconnected it from the vcr and called the cable company. All have lead me to the problem is with the tv. I need some advice on what to do next. Steve Stuck on CBS

What's your problem?Won't stop changing channels


there is every possibility that the channel (ch - and ch +) button on the TV is stuck. This can make the TV channels change by itself. This also applies to the remote control (if any).

Turn off the TV, use your thumb to flip through the channel (ch - and ch +) button on the TV. This will free the stuck button. Also, check the channel (ch - and ch +) buttons on the remove and make sure it is also not stuck in.

If the above doesn't solve the problem, then it means fault is from the control board inside the TV. It maybe defective or needs servicing.

The board controls the buttons on the TV and it can be found on the position of the channel (ch - and ch +) inside the TV.

Note that TV stores a lot of current. So if you want to disassemble the TV to check the board allow the current to discharge by remove the TV plug from the wall and wait for about 1 hour before attempting to disassemble the TV.

Let me know if you need more assistance...

My Volume and Channel button won't work and so I have bout 2 remotes, neither of them have worked, one is the RCR311BR remote which has been noted to work for this tv. What else can I do

I have a 2000 model RCA P52923 and I had the same problem occur a couple of days ago. The sound hasn't worked for a couple of years, but the TV is connected to an RCA surround sound to resolve that issue. Most recently, while watching TV, it began to start scanning channels by itself. I shut it off and unplugged it for a couple of days, but each time that I turn it on, it begins to immediately start scanning each channel. Neither the remote, nor the channel buttons on the set are able to stop the scanning, and neither of them will perform any functions, including turning the set on and off.
Any advice would be greatly appreciated.

Doubt it. We ran HD through our small CATV system using consumer grade modulators but could only get them on the AIR frequencies, as we had very limited bandwidth as we had to carry 64 analog channels plus digital HITS packages for our Motorola DSxxx series boxes. Try plugging the CATV feed into the ANT input and do an autoprogram, or tell the tv to look on the AIR frequencies when it asks if you have CATV or AIR. Worth a shot though.

Verify that you don't have a stuck channel up button on the panel. Next check the solder connections on the IR receiver (3 pins). Also check the +5 supply for excessive ripple. Any of these can cause odd behavior. Let me know how you make out.

Rca model P46920BL

This could be a remote problem, try it while the remote it out of range/no batts if so just replace the remote. Pull the batteries out of the remote - fixed? Then: Check the switches, sometimes people clean the set and fluid drips down corrodes the hidden switches and some components near them. If not that check continuity of the switches Another thought, is if you have compact floresent lamps in the room, these can cause some IR interference that can trigger events on your remote control input. last, does anyone near you has the RCA TV? mybe other remote is effecting your TV...
