Chances are it will need replacement parts (output transistors and a couple of resistors) Probably best left up to a repair shop tech.

Unit is flashing protector volume does not work


The protective device on the receiver has been activated because of a short circuit.

("PROTECTOR" flashes.) Turn off the receiver, eliminate the short-circuit problem and turn on the power again.

http://www.docs.sony.com/release/STRGA8ES.pdf

Generally speaking, an amp protects itself from heat, shorts and overloads.


Overloads can be from excessive periods of high output 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 'naked'. 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 hands-on tech.

It flashes the word - protector


Hiya,
Disconnect all speakers at the receiver and power it back on. If it stays on, check all speaker wires and speakers for shorts (touching wires). If it cuts out, it needs to be serviced.

Mike

Protector comes on and even when all speakers wires are disconnected


Power transistors probably degreased or the greas had hardened and doesnt conduct the heat anymore. Quite touchie work, would suggest it only if u have some knowledge about soldering electronics.

Message "PROTECTOR"


Disconnect all speakers at the receiver and power it back on. If it stays on, check all speaker wires and speakers for shorts. If it cuts out, it needs service. If you need detailed troubleshooting help on this after testing receiver without speakers connected and it passes, post a comment and I can walk you thru it. Hope this helps.

RECIEVER TURNS ON THEN OFF FOUND BLOWN FUSE STR-DE625


Disconnect all speakers, then test power. if it cuts off, your receiver needs serviced. If it stays on, Check all your speaker wires for shorts and connections at speakers. If they seem ok, re-install one speaker wire at a time and test power. once you find the speaker that's causing the problem, replace the wire and connect a different speaker (that you know works) and test again. If it cuts out, the problem is in the receiver and needs serviced. If it plays, put the original speaker on the new wire and test again, If it cuts out, it's a bad speaker or internal crossover depending on the model. Unless you are very proficient with a meter, this is the easiest way to check your connections. If you still have questions, post a comment and I'll help some more Hope this helps

Sony Model: STR-DG800


You've got a short in one of your speaker wires either at the receiver (most common) or at the speaker itself. you should only have a 1/2" of each side of the speaker wire stripped to put on each terminal, and when you strip them, twist them so there are no frays in the strands that will touch the other terminal. The receiver is protecting itself from harm. Turn it off then disconnect all speaker wires, examine each wire carefully before reinstalling, then turn the receiver back on. If it still says protection, look at each speaker and reconnect your wires the same way. If you still have a problem, disconnect the wires again at the receiver and turn on, at this point, if it say's protection, it needs to be serviced. Hope this helps

SONY HT-DWW1600. WHEN GETS NICE AND LOUD TURNS ITSELF OFF AND SAYS PROTECT ON THE DISPLAY. HELP!!!!!!!!!!!!!!!!


It is getting too warm and shutting down to protect itself. This could be caused by insufficient ventilation or by shorted speaker wires.
