SOURCE: HT-Z320 displays PROT code and then shuts down

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

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a possible root cause for intermittent shutdown.

When I turn my system on, it waits 5 seconds, says "PROT" then shuts itself off.


There could be a short circuit in one of the speakers. This would cause high current flow thru the amplifier and result in self-protect. Disconnect all speakers from the unit and try powering up again. If there is no PROT, then reconnect speakers one by one until fault found or all speakers are reconnected.

Ah59 02291a remote wont connect to anything?


If your remote is a Samsung, it should be able to connect to your Samsung HT-C450. Although you say it has batteries in it, those batteries may be no good and fresh ones are needed. You need to determine whether your remote can be programmed to control your Toshiba TV. Instructions for using your remote could be useful for solving this problem.

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


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.
