Something is drawing too much current inside. Chances are it has a bad output device. Repair is more expensive than replacement. Look for one on eBay that works, but has missing knobs or something that you can easily swap. Should be under $50.00.

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.

if you disconnected everything and it still goes into protect, the most likely there is a damaged amp channel that will need to be repaired.

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.

Hi i am a new member and i have a problem with my str-k840p it started to have a protect mode flashing and I can't hear the at all the tv or speakers. What could i do i check all my connection and they...


Hi,
Protect display indicates that receiver is in protection mode due to some serious problem in output amplifier section and most probably any output channel output chips got shorted out.
Protection mode turns On to avoid any further damage in receiver. If your Sony STR-K840P is under warranty then call numbers written on warranty documents to ask warranty cover and if unit is out of warranty then either Sony service center or local repair shop will help you to get it fixed, it is not user level repair.
Hope these info will help you.
Let me know if you have additional question.
Thanks.
