Hello,
Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Usually a protect fault will indicate a bad transistor in the amplification section. I suspect that the control circuit is sensing a fluctuation in the power supply and going in to protect mode. (assuming that the protect circuit itself is working properly) If a voltage is too high the unit will go in to protect mode to prevent damage to the speakers and the rest of the unit. Expect a 60 to 80 dollar repair charge depending on how many parts need to be replaced and what the repair labor rate is in your area.Hope this will help........

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.

"Protect" error - HTZ110


Home Theater System Is Displaying "Protection" spacer.gif As soon as the unit is turned on, the word "PROTECTION" will flash on the front panel of the unit and SHUT OFF. This error message usually indicates that the fan in the back of the unit is not on.

The PROTECTION feature automatically shuts down the unit to avoid further damage. The unit will need service if this error message is displayed.
