This means that the amp has detected a short, or low impedence and has shut down. check all the speakers for bad connections and shorts.

How do you get bubbles out of iPad screen protector?


To lift the protector off one edge of the display, place a sticky tape on the edge of the protector and then pull on the sticky tape to lift off the protector.
Lift the screen protector from one edge, peel it back to the last bubble then re-fix the protector in place by slowly apply pressure across the proctector as you push the protector onto the display making sure no bubbles forms between the display and the protector.

Make sure none of the speaker wires are touching each other. If they are, it will short out the stereo which triggers protection mode and cuts out all of the sound.

Try to unplug the power adapter from the printer.

Wait at least 10 sec before replugging the adapter. This will give enough time for the printer to reset itself. Also, make sure the printer is plugged in straight to the power outlet in the wall and bypass any power surge protectors.

My STR-DE925 reciever isn't giving me any sound. When i turn it on everything works like normal, kicks on, and there is a click; but after a few seconds the display switches from whatever input it was on...


check speaker connections.sounds like the system is trying to stop some thing more serious happening by shutting itself down.a pain yes but saves blowing something up.if no luck,then definately send in for repair

It blinks PROTECTOR


This means that the unit detected a problem and shut itself down to prevent further damage. The normal cuase of this is a defective transistor in the final amplifier stage. Figure on $15-$35 for parts plus the local labor rate for the total repair.
