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.

Regards.

Machine keeps powering off randomly


I'd be willing to bet you receive a Protection error just before powering off. If you take the cover off, you probably have a burned capacitor in front of the fan. that was my problem too. Samsung was no help, and it happened just after the warranty expired, as it has to many many others with this unit..

It keeps on wanting to shut off like it is overheating but yet it is not hot...(Samsung DVD home theater system HT-TX72)


Check you speaker connection first and make sure none of the wires are touching another terminal. The unit might be going into protect mode. If so it should display the words protect on the display before shuting down. Try removing one speaker at a time while turning on the unit after each speaker is removed at a time, to see if it shuts down on you. When and if it stays on then the previous speaker you took off is defective.. If none of this works then you might have a bad Preamp circuit or main amplifier output problem. Disconnect everything from the unit and turn it on, to see if it shuts down on its own, if so then there is a problem with the internal parts of the unit itself.

I have a samsung ht-tx75 and it keeps shutting down every 10 minutes saying protection.the fan is working


Protection is very likely caused by an over heat condition, even with the fan working if the receiver is in a very enclosed place that warms up and is not ventilated it will cause the problem. The solution is to provide more ventilation so that the receiver can cool itself properly.

Samsung home theater


After having my unit for a year, it now reads this PROTECTION message. I tried to restore factory settings also before calling Samsung & they said something wrong with the cooling fan. Haven't tore into it yet, but does the units come with a fuse that might be blown. I'm tring to find free schematics on the net but hard to track down. If you just got yours, take it back to the store & get a new one!
