Question about Sony LBT-XGR600 CD Shelf System

2 Answers

"Protect" and "Push Power"

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: "Protect" and "Push Power"

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.

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

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.

Power protect tends to mean the main power amp chip has "blown" and needs to be replaced. It only costs about 20 dollars (10GBP). If you are handy with a soldering iron it is easy to do (after you get the thing to bits !) It is the big black thing on the big heatsink inside. The Sony part number is STK442 - 130. Seems a waste to throw the whole thing away for the sake of 10 pounds !. Hope this helps. Nik Howell (
