I have a samsung HT-Z320 home theater system. when i turn it on it says PROT then shuts off. why?

PROT means that the AMP is protecting itself from damage due to bad or incorrect wiring or damaged and or incorrect speakers. Check your wiring and speakers.
If you find no problem then, DISCONNECT YOUR SYSTEM FROM THE POWER, disconnect your speaker wires...all of them, then reconnect the power ONLY, turn on the system and see if it still says PROT. If it does then your amp is damaged.

its protection mode a failsafe put in place to shut down the unit in the event of a possible critical failure .......maybe a fuse.......maybe a dead system your budget will decide what your next step is ok good luck

hello, prot mean protect the output transistor may have blown or a capacitor has poped or swelled up or the just could be a case of a dry joint

when i turn on my Samsung HT-C550 IT showing PROT and DVD turn off. What this is mean PROT?

Go to http://www.retrevo.com/support/Samsung-HT-Z320-Home-Theater-Systems-manual/id/23345bh451/t/2/ for the manual download.

the easiest way to get signal to your HT-Z320 is to run the audio cables from your cable or sat box to the input on your theater system...for the dvd either run HDMI to the LED TV or component (whatever it supports) the Wii system can be plugged into any AV -IN on the LED tv (if you want to use the Wii on the theater system you will need to extend your RED AND WHITE audio signal cables to the input on your theater system.

Hope this helps.

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

output on TV cable digital reciever to home theater digital reciever in via an optical cable.lower the volume on the TV cable digital reciever to get the most out of the surround sound system.

I'm guessing that you would like all your components to play audio through the HTZ320. In order to get audio from all these components you will need a digital optical cable from the tv optical out to the HTZ320 optical input. And some composit audio cables (red and white) from tv audio out to the HTZ320 aux input. The video and audio from the dish box, bluray, and the vcr are all going to have to go through the tv first and then to the HTZ320. Use HDMI cables to connect the dish box and the bluray to the tv inputs and composit cables (red white and yellow) from the vcr output to the tv input. If you can give the exact model of the tv I can help you sort things out further. I hope this helps you.

Use a fiber optic cable
