27'' TV will not turn off demo mode

Press and hold the VOLUME UP and VOLUME DOWN front panel buttons at the same time. This will take the TV out of that demo mode.

The tv has been accidentally set for "demo mode". Press the volume up and volume down buttons in front of the TV at the same time for about 5 to 10 seconds untill the demo disappears or sometimes the TV will turn off. You should regain control of the TV after this.

Those older Magnavox sets had a demo mode available from the on screen menu. Go to the menu and disable the demo mode, that will fix the trouble. When in the demo mode you will have no control over your set by remote or front panel controls. You can still address the menu though to turn off the demo mode.

I have exactly the same problem with a Magnavox LCD 42", very similar model 42MF437B/37. I don't have a solution. If you unplug the TV and plug it back it starts working, sometimes for hours, sometimes for less than 5 minutes, before it turns off again. Does anyone have any real solution?

on the set press and hold the up and down volume buttons together till the tv turns off then press power to turn back on and everything should be fine

To disable the Demo mode, perform the following:

1. Turn GA_googleFillSlot("TL-IMU-Article"); on the TV.
2. Simultaneously hold down the Vol+ and Vol- buttons on the front of the TV. Do not use the remote control.
3. Hold for about 6 seconds
4. Certain model TVs may turn off, others will not. But in either case, the Demo mode should be disabled.

THANKS FOR THE INFORMATION ThaMp3DOCTOR. PRESSING THE VOLUME+and CHANNEL+ SIMULTANEOUSLY FOR 5 SECONDS WORKED!   THANKS

To exit from factory mode, press the 'VOLUME(-)' and 'CHANNEL(-)' buttons on the TV set simultaneous for 5 seconds.

My wife somehow put our Magnavox TV into demo mode too...

Plug in the set. With the set ON. Press the volume up (+) AND volume down (-) at the same time.

This worked to get it out of demo mode!
