Hello.. I have Sony MHCEX500 MINI HIFI Component system. There is a problem of PUSH POWER PROTECT. How can I fix it..????


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?

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 (nh@totalise.co.uk)
