SOURCE: Sony STR DB-930 Receiver jumping into protector mode

I went through the amp/receiver and used small star washers on all the grounding screws I could find including the one securing the transformer, cleaned dust off all circuit boards, checked output transistors and fuses, all OK.

Re Assembled unit and it worked OK.

I will buy a fan and fan it to avoid sourcing heatsinks for the previusly suggested IC's.

Thanks for the technical help, sure solved my problem.

Regards

Darryl.

SOURCE: stuck in protect mode

Protet mode is a special diagnostic mode that starts when a fault is detected.

When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.

Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.

Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.

If you do all the above and still get Protect, then there is a real fault.

In that case the unit may be disassembled and tested to find the fault.

If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.

Protect mode


I didn't see any mention of it in the STR-D565 manual, but on many other Sony models the "Protect" indicates a short in a speaker wire.

Having problems with my SONY str-db798 amp. When i turn it on (without any speakers or even with speakers) it flashes "PROTECT" and shuts down. Any suggestions how to deal with it without getting...


Press and hold down the power button on the front panel until you hear a secondary "click" from inside the chassis. That takes about 15 seconds.

Then read my tutorial on how to keep your receiver out of protect mode.

I have rewired my receiver and the SOny str-d565 keeps shutting off. Is this fixable or should I just get a new receiver?


This unit most likely has shorted output transistors. The unit is entering protect mode which will prevent further damage to the unit. Expect a parts cost in the $40 range for this repair.

How to bypass protection mode on my sony receiver


The protection mode is there for a reason...the main one being to protect your speakers in the event that there is an issue with the amplifier. Bypassing the protection can easily result in the destruction of your speakers and the unit itself. Your receiver needs to be examined by a real live technician.
