Re: protection

Protection means the unit is detecting a short somewhere. Disconnect speakers and components and attempt to power on the unit again. If it will power on with nothing connected, repeat the process (turn off, connect something, then power on) until you find the bad component or speaker.

When i turn the system on the display will read "hello" then "protect" then shuts off. Whats up ?

The "protect" function is shutting the syetm down to protect the electronic components inside it. Usually caused by a lackof earth in the plug or extension lead. Plug it straight into the wall and check it, if it is still the same then it could be a speaker wiring short circuit, disconnect the speakers and plug it in on its own and test it

Fan chk problem too

it means the home theater is over heating and the unit will shut down to prevent any damage. This can happen if the unit is stacked along with other electronic devices or the unit is in an enclosed area that prevents the unit from cooling properly. To decrease the chance of overheating, relocate your home theater to a more open area.

If the home theater display reads PROTECTION every time you turn it on, no matter where or how the unit is placed, it needs service. To set up service call Samsung Customer Care at 1-800-SAMSUNG (1-800-726-7864). Have your model number and serial number on hand to set up service.

I have a samsung home theater system HT-X70. After 10 to 15 minutes the word protection scrolls across the screen then goodbye and finally the unit shuts itself off.

ther is dc voltage applying your speakers by amplifire itself and turn on speaker protection circuit itself.
it can be happens because
1.loose connection in amplifire board
2.faulty output section of amplifire
3.short circuit of speakers
4.error detecting circuit faulty.
if youcan open the cover and clean the circuit for dust and resolder the circuit with 30 W soldering iron cairfully.if you want the more asistence please come again
ican hlp you more.

Unit shuts itself off after 10 -15 minutes

Protect mode will kick in whenever a fault is detected.

You get the unit not powering up, and sometimes you hear a clicking noise, that is the protection switch that keeps shutting down the unit.

Causes that can start protect mode are:

Electrostatic harges on internal circuits.
Leave the unit unplugged for power for one hour or so, this will allow discharge.

Bad speaker wiring.
Check speaker wiring, try unplugging and plugging back, or start after removing one speaker at the time.

Internal fault.
Internal fault is the natural cause for protect mode. If all the above did not work, then the problem is a blown component or an internal fault. In this case the unit must be taken apart , tested and repaired by an experienced person.
If the unit is less than one year old, or if you want to get service, call Sony at the phone number listed on the product documentation.

sounds like you may have your speakers connected wrong or too many speakers. Check all your speaker wires for a goo tight connection and speaker compatibility with your Home theater system. Hope this will help you

Take every single cable out of the unit, now power on the unit.

If the power protection still shows then there is an internal fault, usually a short or a component defect.

If it powers on ok, switch off and insert 1 speaker at a time and power on the unit until the protection mode comes on again, the last speaker you have put in has overloaded it for some reason, also as you are trying each speaker use the volume and bass controls to see if there is an internal overload.

Thats as much as I can offer you until you narrow the fault down to the unit or one of the speakers.

Powers off by itself and says "problem"

This message is supposed to indicate that you have wires crossed at some point. Maybe the speaker wires are touching? I have a similar issue, however my receiver does not say Protection - it just says Goodbye. Samsung support says that this is an issue with the box and likely needs to be replaced.

Check all of your speaker wires, and call the Samsung support 800 number. They are pretty good.
