    Thanks for the responds, it could be the power output amplifier. Since I disconnected all the possible overload or short ckts, like the speakers, dvd player, and cassette players section still, the same message on the display. Maybe its time to bring it to the service center. Thanks again.

Before sending it to service, temporarily replace the speakers and wires to see if there is a short. If it works with the replacements, you have a shorted wire or speaker that needs to be fixed.

You could possibly have a simple overload on the unit, depending if it is like a HTIB w/speaker outputs or if it just a DVD player. Wires could be crossed. etc.

That means the output circuit has a problem and you will need to have the unit serviced.

Hii I have sony shake 6D system and whenever I turn the volume up it reaches upto 40 and shows the error of 'protect E01' while the maximum volume is 50. Please help


Most likely, your unit is shutting down due to overheating. You cannot run an amp at that kind of volume very long. It is shutting down to protect itself. Try running the amp at 1/3 your normal level. Most likely, it will not shut down.

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

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.

When i turn on my samsung HT-Z110, the word "Protect" appears...


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 mode shuts down the receiver


If this happens only when connecting the receiver, chech the receiver cable. If the cable is fine, receiver connector at the back of receiver is faulty.

F61 is a problem with the output amplifier pac. It is the equivalent of "protect" mode. The output pac needs to be replaced. I'll look up the part number for you.

Protect


The protect message indicates that a problem was found in the output stage of the amplifier. Unless this gets repaired, nothing will work. As a verification that the speakers or the wires are not the problem, unplug all of the speakers and try again. If protect still is displayed, the problem is inside the unit.
