Resetting won't solve your problem. The display is telling you there has been some internal damage ( most probably output stage ) and needs fixing.The system goes into protection mode to prevent further damage.

Hello can u help me about my MHC-gzx55d sony hifi component, when you turn on the power, the screen display appear "PROTECT" what is the problem and what is the possible damage of my component. please help...


When it goes into protect mode it has been over loaded. Remove everything from the component and unplug the unit for a minute or two. plug it back in and see if it pops out of protect mode. If this does not work then you will need to do a factory reset or check the fuses on the inside of the unit.

How do I reset a technics sa-gx350 receiver unit


Don't know that you can actually reset this unit like the new digital receivers. It does have protection circuitry that will shut the unit down in case speaker wires are shorted or if speaker impedance is less than the indicated rated impedance of the amp. do the following:
1. Turn off power and unplug from wall.
2. Check all connections and correct if needed.
3. Turn back on after 1-2 minutes.
If unit is still in protect mode you may want to unplug everything from the unit and then power back up to see if the problem is internal or external. If it powers up correctly then the problem is external. Power back down and plug in one external item at a time and power back up between connecting each item to see which item causes the receiver to go into protection mode.
If problem seems to be internal I'd recommend taking to an electronics repair shop if you aren't comfortable with taking apart to check fuses, terminations, etc. There may be a 5-amp fuse in the power plug head also.

Our electricity went out for a few minutes, and since then the TV will not turn on. The green light is flashing. We tried resetting it by pushing a pen point into the reset hole, but it does nothing. ...


Your power outage may have been caused by a nearby lightning strike, or any number of
1000 different reasons that cause power surges, brown-outs, voltage spikes, inductive loading,
and/or utility pole breaker trips and resets (this accounts for your power loss (a pole breaker trip),
followed by restoration of power (the pole breaker automatically reset) - even plain old high electrical demand causing an overload due to air conditioning demands caused by hot weather.
When the pole breaker reset, your TV caught a power surge.
Whenever a power outage occurs, quickly power off (or better, unplug) any/all computers, TVs,
etc. that are not protected by surge-protection.
As an electrician, when someone loses an item of electronics concommitant to an electrical
anomaly, its almost
always traceable to a nearby lightning strike (or the power company provided equivalent), accompanied by inadequate surge protection for
the VCR/TV/Computer/Stereo/uninsured valuable electronic item/XBOX 360/Nintendo Wii.
Surge protection can
be provided by the consumer at the power strip (a good one with builtin MOV protection and a
warranty costs $20, whereas a zero-protection 4-outlet or 6-outlet power strip will cost $4-$5).
Your electrician can provide whole-house surge protection where a whole-house MOV-based (metal oxide varistor) surge protector, or per-circuit protection can be installed with
a GFCI breaker (or better, an AFCI breaker) can be installed.
GFCI = ground fault circuit interruptor
AFCI = Arc fault circuit interruptor
Lightning protection is especially important in Florida, which is the "lightning capital of the world."
I've never found a good solution to lightning-fried electronics (random power supply components are destroyed and/or fuse blown), other than renters insurance or homeowners insurance.

Your only real hope for an economical fix is to look for a blown fuse, and replace it.

If desperate to attempt a fix on your own, you could try replacing the entire TV power supply as a module, but even this provides
no guarantee of a fix - lightning damage can extend beyond the power supply.
When traveling, I will always unplug everything before I leave (except the security system),
and also turn off the breakers to unneeded house circuits (which kills the wall switches that
control interior lighting - forcing a burglar to use their flashlight instead of interior lighting)
which is the least convenient lightning protection, but highly effective, and cheap (free).

Got Clover LCD2084, I try turn-on and only make loud sound and the power turn red and the screen is black.


I would unplug everything from the back of the system, clean the connections with a brush and rubbing alcohol, then plug everything back in. Turn it on and see if you get the same problem. If so then try unplugging the cameras and see if the noise stops. If the noise stops then one at a time I would plug the cameras in watching to see if you get a picture and/or sound. You may have a bad camera that is sending a short to the system that sends the system in to a protection mode.

My stereo won't work. Whenever I try to turn it on, it always turns off saying "protect." How can I fix this?


The protect has come on because it senses an output load problem, Turn the unit off, unhook the speakers and wires from the stereo, now turn the unit on and turn the volume down as far as it will go, this should reset the processor ic, if the word protect stays off you have a short in the wiring or bad speaker. If the protect comes back on with everything unhooked the problem is in the audio output ic pack in the stereo and will require a technician to remedy.

I have a Sony receiver STR-DG510. I was playing music through the receiver when it suddenly stopped and displayed/flashed protect. After unplugging everything and trying a different power outlet it still...


Most likley it is a bad channel. Needs output transistors and a couple of resistors. or it may need a pre-amp voltage ic.

Not a repair for your average do it yourselfer.

I have a samsung DVD Home Theater System HT-WX70. My son put a cd copy in the DVD player and PROTECTION flashed on the player and it turned off. I turned the player back on and took the cd out. ...


If it is, the protection message usually meant either a speaker had blown, or more commonly a wire to a speaker had come disconnected or broken/shorted.

Try unplugging the speakers one at a time, and if you have a set of speakers of the same rating to try, try plugging them in as you remove the originals (obviously doesn't need to be done in the setup positions in the room, just have them beside the player to check it works.)

This might then identify which speaker or cable is the problem one for you to replace or repair.

If this is the speaker overload/short mesaage as I think it is and the above doesn't cure it, it would appear the amplifier board has a short somewhere and that's an electronics engineer job time
Hope it helps!

Stuck in protect mode


Speakers shorted out, blew a fuse. Replace the unit or (cross your fingers and) open up the box and find the blown fuse.
