SOURCE: SAMSUNG HT-TZ212 home cinema kit comes up with protect
Protect mode will kicking whenever a fault is detected.
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.

check if there is anything blocking the fan from moving/rotating
try to contact your manufacturer
SOURCE: Samsung HT-TZ312 shows "protect" and it turns off
A short on the speaker wires can cause this but most likely your amplifier bias is off or you have a shorted transistor.
First unplug all connections, even the power. Let it sit for a minuit then power it back up.
If it clicks off them it needs professional service.
If it turns on inspect all of your speaker wires for shorts them reconnect them one at a time.
Hope this helps,
Cheers
SOURCE: how to take protect mode
The protect mode as it means is the safety cut off due to a possible error or shortin in the DVD.
You must have to identify the fault before we can conclude on the position of the fault.
So start from the power supply chek votages, if the main voltages are present. Remove leads to the DVD drive and check, if OK then the drive section is faulty. But fault can vary from the AV section to the decorder stage and to the drive.
The microprocessor control is however working as it indicates the fault.
So proceed by elimination
SOURCE: How to quit Protect mode
You don't quit it, you resolve it. It's there for your safety.
Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.
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 'nekkid'. 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 another possible root cause for intermittent shutdown.
