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 (nh@totalise.co.uk)

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 .


Hi,
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.

Resetting stopwatch dials - Armani AR5331


When you reset the big seconds hand to zero, the hour and the minute hand are not engaged in this function, so, there is no fault with the watch movement.
Do as follows:
1) pull out crown and set the hour and minute hands at 6 o'clock (they must be lined perfectly in opposite directions)
2) push the crown in half way back (not completely)
3) push and hold the button at 2 o'clock (set the big seconds hand to zero) and release it when done
4) when big seconds hand is zeroed push the crown back in
5) pull the crown out again and set desired time
6) push the crown back in.
If all actions described do not work, you will have to visit your nearest watch repair shop and ask to refit chronograph hand as in this case it is out of balance (not pointed at exact mark).

Rate me, please.
