The tv cut off after turning it on repeatedly for minutes before it stays on while. I does repeat after an hour or two.''philip magnavox pr1920 c601

I suggest you try these steps..

1.Turn the television set on by pressing the "Power" button on the set.

2. Find the "Code Search" button on the Philips Magnavox remote. This button will be labeled or will be a different color than the other buttons on the remote (depending on which Philips Magnavox remote you own)

3. Hold the "Code Search" button down for about ten straight seconds. The light on the Philips Magnavox remote should then stay on.

4. Starting pressing either the "Up" or "Down" channel button on the Philips Magnavox remote. Continue pressing the same button until the television responds to the remote. It could take a few minutes for the channel to change so you'll need to have patience when searching for the remote code in this manner.

5. Press the power button on the Philips Magnavox remote once the channel has changes. If the device shuts off, press the power button again to turn the TV back on. If the TV turns on, the remote has been programmed correctly. Repeat the entire process if your remote is not programmed.

I hope this helps...

there are several. try each one seperate.

1. press and hold setup button until the red light stays on.
2. press and release the desired mode button (example t. v.) the light will blink and then stay on.
3. enter one of the 4digit codes.
note: if the code is valid the light will turn off if it flashes it is an invalid code.
4. with the device on press the channel up and down. if the remote only controls some of the functions try another code.


these steps will set up the first device and then to set up the second device just repeat the steps choosing the other device and the code for it.


CODES: for the tv: 0514,1174,0062,0204,0184,0208,0205,0206,0207,0004,0189,0183,0019,0200,0081,1149,1154,0288,0456,0003,0008,0068,0075,0086,0087,0141

If none of the the codes work try following these steps:

1.manually turn on the t.v.
2.press and hold the setup button.
3. press and release the tv button the light will blink once and then stay on.
4.press the channel button repeatedly up to 300 times until the device changes channels. the light will blink and then stay lit.

TV shutting off automatically means its a problem with the Lamp. Contact Pioneer or any local tech shop or Best buy and get the same replaced.
Turning off after specific time : Go to the timer option and disable the Automatically Switch off option. This will resolve the issue. Please let me know if it worked. If you need the user manual or instruction manula please click on the link below

This is the user's manual for a Phillips remote control. There is a list of codes in it. They should be rather universal. There's also instructions as to how to program it. I believe that there is a way to program it without using the codes.

Programming with Code Search

1. Manually turn on the device (TV, VCR, etc.) to be controlled.

2. Press and hold Code Search button until the red indicator stays on. Release the Code Search button.

3. Press and release the desired mode button (TV, VCR, etc.). The red indicator blink, then stays lit.

4. Press the Channel Up button repeatedly (up to 300 times) until the device could be controlled changes channel. The red indicator blinks, then stays lit. If you accidentally overshoot the code required, press the Channel Down button to backtrack through the library until the device changes channel. Pressing Channel Up changes direction to forward again. Press and release the Mute button to install the code.

Hope this helps :)
