While playing my unit we had a brief power outage. When the power supply returned the " PROTECT PUSH POWER " message comes on. Is there a button that I can push to reset my unit-LBT-X50 .

Your sound system may have a circuit breaker.
Check the rear of the sound system for a circuit breaker that has popped out, Then push it back in.
It may be labelled.
  • circuit breaker
  • protect push power
Otherwise unplug your unit from the wall and wait 5min before you plug it back in, then press the power button on the front of your system and your remote control.

I hope this helps

Hi - I just moved and when I hooked up my 2003 Panasonic SC-AK100, it stays in 'demo' mode and won't shut off completely...after showing "goodbye" and apparently shutting off, it comes back on...

Page 12:

A demonstration of the display is shown if you have not set the clock.

You can reduce the power consumed in standby mode by turning it


During standby mode

Hold down ['square icon'/-DEMO] until "NO DEMO" is displayed.

Every time you hold down the button:

NO DEMO (off)↔DEMO ON (on)

To show a demonstration of the display
Hold down ['square icon'/-DEMO] until "DEMO ON" is displayed.

Sony LBT W5000

According to Page 46 of the LBT-W5000 Operating Instructions:
"The display stars flashing as soon as you plug in the power cord even though you haven't turned on the system (demonstration mode).
Press DISPLAY (for LBT-W5000 / W300 / XB700 / XB500) or DEMO (STANDBY) (for other models) while the system is off. If the system is in the Power Saving mode, press POWER SAVE / DEMO (STANDBY) (for LBT-W5000 / W300 / XB700 / XB500). The demonstration appears automatically the first time you plug in the power cord, or if there is a power outage lasting longer than half a day."
I tested this today, as my LBT-W5000 was in Demonstration Mode. It definitely works. The only catch is (at least on the W5000), and it's a minor one, you have to reset your clock afterwards.

Protect message

Protect means that a problem was dtected and the output amplifier section has been disabled to prevent further damage. The typical failure parts are the output transistors. Expect a parts cost between $15-$40. Add in the local labor rate for the total repair cost.

Protection displayed and shuts off

The protect message indicates that the output amp section has a problem. Normally this requires the replacement of the output transistors or the output amp pac. Expect the repair cost to be about $20-$60 for parts plus the local labor rate.
