Question about Samsung 1000W 5.1-Ch. Home Theater System with Upconvert DVD Player
Check the impedance (resistance) on all the speakers and the speaker wires themselves.
Power up the unit with no speakers or inputs attached at minimum volume and see if it still goes into protection mode.
Most speakers should measure between 4 and 8 ohms for most systems when disconnected from the receiver.
If the unit says PROT even with no inputs at minimum volume with the speakers detached, then there's a problem with the amplifier itself, probably in the output section.

i had the same problem a prot display then it would shut down. turns out i had the sub disconnected(noise complaint from the shaking at my apartment complex) but the speaker wires for the sub connected to the amp or central unit. when i disconnected the sub i left the wires on the floor behind the sub separating the pos. and neg. somehow the wires got moved around and the pos was touching the neg. as soon as i noticed and fixed this problem the system was working fine. my samsung hometheater model is HT-BD1250
