There is no reset button on the unit.
This message usually means that there is a short in the speaker wiring. When a short is detected, the unit protects the unit by not "pushing" any power to the speakers.
Can you remove all of the speaker wiring at the back and ensure there are no stray strands of copper wire, then re-insert the speaker wires into the correct holes. Also check all of the wire length to ensure that none of the insulation is damaged. Then power on the system again. If no short is detected, the Push Power Protector error message will disappear.
If there are signs of damage on the bottom of the unit, then some component of the speaker amplifier inside the unit is probably damaged. Did you notice any signs of incorrect wiring or shorts in the speaker wiring that could have caused this? Did you have the speakers connected to the correct location on the unit?
Your main amplifier is pumping out 1000W, while the smallest surround speakers only need 50W, so if anything has been connected incorrectly or has shorted, this can cause major damage to the unit. You would be best getting a quote for repair from a technician first, as the cost of repair could be almost the price of a new unit - the amplifier is the costliest part of the unit.
