Sounds like you may have had some fluid go from the screen to the buttons on the main board...like Windex or something, and is causing a short in the buttons. The only way to repair it is to have the main board removed and cleaned or have those buttons replaced.

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.

Magnavox PJTV model 51mp392/17 -pressing channel buttons changes


You need a professional.
Your TV has "lost is mind"

Stop using the TV until it is repaired.
Continue to use it and your problems will multiply and grow more expensive.
Call the manufacturer to find you nearest authorized service center.

Philips universal remote codes


For the majority of phillips/magnavox universal remotes: Hold code search button down till red light satys on. Press the tv button and the red light should blink and stay lit. With the tv on, push the power button repeatedly until the tv turns off.(dont push the power button again after the tv turns off or it will go to the next code). Push the mute button to save the setting.
