it is your protection circuit working, preventing the unit from any further damage to circuitry. you can check first your speaker cabling for any short connections, possibly red/black terminal wires got entangled. if all ok then try removing all speakers then turn on the amp. if still does the same thing turning off then you have a problem with the amp output stage, shorted power output transistrs/driver probably. if the unit turns on normal without the speakers then you must have one or both of your speakers busted. by the way this amp is multi channel, after removing ALL the speakers connected, and does not turn off anymore, put the speakers back one by one and observe if the unit with turn off and on which set of speakers. otherwise if still trips even without the speakers, it is your amplifier that is deffeective, any of the five channels, main, rear,center. let me know result so i can guide you on how you can get it repaired and what will be the extent of damage in case.

Does the reciever have separate speaker switches?
Try turning off the speakers and turning on the amp.
If it doesnt have speaker switches , make sure ALL the speakers are connected at both ends and try turning on the amp again.

What connection do you use?
This receiver supports both video and audio over HDMI. It has also other video inputs, but it doesn't have any video processing.
So if you connect your equipment for example to component video in, its video output will be present only on component video out (NOT on the HDMI output nor s-video output).

It is one ot two things, the audio output transistors or ic,s are shorted, or the speaker wires in the back of the surround sound are shorting.
