Question about Sharp CD-PC3500 CD Shelf System

1 Answer

PROTECT I have this stereo, but everytime I turn it on it displays normally and then shuts off and the word Protect flashes on the display repeatedly. Once this happens there is no other functions that work on it, has anyone run across this problem if so how do I fix it? I have tried unplugging it and waiting, and resetting the computer but nothing works.

My JVC mx-gc5 stereo says protect and then shuts off

If protect is coming up on the display, it means the system is detecting a short somewhere on one of the speakers and so is turning the amp off to avoid damage.
Check all the connections at the back of the amp to ensure they are not shorting, and at the back of each speaker, if nothing is found there, check each wire for damage (like squashed or rodent damage).

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.

That demo mode thing is painfully annoying. With mine, I had to hold the 'display/demo' button in for about 1 second and then the words "NO DEMO" appeared. That fixed it.

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.
