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

Protect Unplug


I know that almost all new equipment since 99 or so on up has these. They are too sensitive. This is a system program that will put stereo in protect mode when turned up loud or have a lot of bass on to stop from blowing audio outputs.

Sony home theater system started blinking 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.

I think, your Home theater gives you error message " protect unplug", means home theater has problem in Amplifier section and will not be power up to function.
You should check Amp section aspacialy Amp Output stage.

Protect


The protect message indicates a problem was found inside the amplifier. The output transistors are most likely shorted and need to be replaced. This is a fairly simple repair and should cost about $40 in parts plus your local labor charge.
