Question about Sony STR-DE597 Receiver

1 Answer

Stuck in HP 2CH

Hello,
I have a sony str-de597. It was in the protect mode, but I repaired that with two transistors that were shorted. I now turn it on, and after clearing everything, it is stuck in headphone mode. I do hear audio from my headphones, but it will not work out of the speakers. Also, when you push a button on the front panel, they seem to be off. For instance, I push MD/Tape, and SA/CD mode shows up. Other buttons seem to work, and then don't, or the display goofs up, and then it works. Anyone seen this type of problem? The remote works fine when accessing modes, so if I could get the headphone problem solved, that would be great.
Thank you

One of the transistors seem to have been installed in the wrong direction.if it is working it will blow off again As for the remote , it works via a separate circuit.

Stuck in protect mode


There's nothing more you can do. It is likely a shorted output transistor that became damaged when either playing too loud for too long, connected to shorten speaker wires, etc. A repair shop or replacement will be you best options.

Won't go off protect mode


When the speaker wires shorted to each other, the output transistors for that channel probably shorted as well. This means that the receiver needs repair. The typical parts cost for this usually runs between $20-$40.

Amp output is damaged and needs repaired. Protect mode cannot be deactivated. When amp is repaired and operating normally protect mode will not be displayed.

My receiver changes to "protect" then clicks off


Since you had to change the fuse to get it to power on, chances are you have a damaged receiver. You can try resetting the system (instructions below) but I doubt this will provide relief. When a system is doing what yours is, it is more often than not a sign of a short in the system causing excessive power consumption. Many times such problems in the final amplifier section, in the form of shorted output transistors. This most often happens from running with the wrong impedance load, shorted speakers connected, loud volume with inadequate ventilation (high heat conditions) or running the receiver without speakers connected.
Try resetting using the front panel controls. Power off. Then holding the 2 channel button down, power on. You see an abrv reset message. If after doing this you still have the same issue, it's time to investigate repair facilities or due to possibly high cost of repairs simply retire the unit and get another.

Flushing "PROTECT" on the screen of a SONY STR DG 910 Receiver


Try connecting one speaker at a time. The "protect" indicates a short or improper impedence (ohms) in one of the speaker lines. it may not be directly shorted, but I'll need to know what you have hooked up for speakers. Also, do you have any electronic meters?

Sony STR-D611 receiver goes into protect mode when turned on.


I cleaned the contacts on the transistors and it's working great now. Previously, I spilled some drink on the unit and it went into protect mode and it was in the power amp section. It's all up and running again. Thanks for the info. --Steve B.

Stuck protector mode


find out why the fuse blew in the first place.the protector is just PROTECTING the main circuits of the receiver.the receiver turns on just to confirm the power circuit is OK.
have it checked by an electronic engineer.
