My Sony LBT-XGR60 stopped suddenly and displays "Protect" and "Push Power" alternately. I followed the troubleshooting directions in the manual several times, turning off the power and leaving it off for 1/2 hour, then turning it back on. Still the same. It makes a little whirring sound and then "Protect" and "Push Power" come back on. This happened once before, last year, and I was able to fix it by turning it off. I checked all of the speaker cables - everything appears to be OK. This is a school, and the player gets very hard use. Thank you for any ideas you can give me.

Re:
Doiuble check your wiresa again for no pinches or shorts, even at the back of the unit. Also try unplugging the unit for 12 to 24 hours. If that does not help, it may be the time to buy a new stereo because that means there is a fault in the output device, unless you kinow someone who can trouble shoot and repair solid state electronics.

The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.
1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

You may also refer to the following link for additional troubleshooting steps.
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.
