Protector is alway on even with no speakers

Failed device, probably a shorted transistor in the main amp section. Suspect any or all the devices attached to the big heat sink.

I have a Sony STR-DE595 receiver that I would like to connect to powered speakers. How do I do this?

One way would be to follow the directions supplied with the unidentified powered speakers. Lacking details we can't really provide a good answer.

My sony STR-DE345 amp says "protect" and there is

The manual says it thinks there is a short circuit on the amplifier output side. If it still says Protect after disconnncting all the speakers wires there is an internal problem. Take it to a hands-on tech.

If the problem disappears, you had a short. Attach speakers one at a time to isolate the cause.

Yes I have a problem with my sony str de 525 receiver its stuck on Protecter every time i turn in on it flashes protecter and i cant get it to stop what do i do

Disconnect the speaker wires from the rear panel, turn the volume down, and see if the receiver still goes into protect when you turn it on. If it doesn't, you need to check your speakers and wiring. You may have a speaker that's gone bad, or a wire that's shorted. Likely causes are too much insulation removed when you stripped the ends and now they are touching, the wire's been pierced by a mounting nail or staple, or it's been damaged somehow.

If the receiver still goes into protection with no speaker load, it's the receiver at fault. I have seen this problem caused by bad solder connections on several areas, bad components in the power supply, and trouble in the amplifier section.

I can't point you toward any specific "most likely" cause, but the bad soldering is something you can check by eye. Any other cause is probably going to require service by a technician who has the test equipment and service information to do more in-depth troubleshooting.

Good luck, and thanks for using Fixya!

Shutdown 10 second


The display "PROTECT" and the auto-shutdown is indicative that the Sony STR-DA5000ES senses an internal fault and powers off automatically to prevent further damage. The fault may either be in the amplifier section, the power supply section and/or the logic board (mini computer).

Initially, try a full hard reset, that is unplug from the mains for a couple of hours to hopefully revert the unit back to factory default (that is assuming no hardware problem). Additionally, you may want to check the speaker and the speaker wires for any open/breaks or short.

If above steps are not corrective, you may need to seek the services of a qualified professional or a service center since this would require on-site/in-shop repair, knowledge of electronic circuitry and components, a full service manual or at the very least a schematic diagram with voltage readings, a DVM and a soldering iron.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.

Noise and popping on Sony STR-DA3ES

Sounds like its going to square wave clipping and poking a dc offset at your speakers. Happens when the amp reaches power supply ceilings. Pink noise such as "rain sound" will push the output stages and power supply to limits. If its on all channels, check power supply caps and check for dry solder joints. also look for that crappy brown hold down glue that goes conductive/corrosive. check all output stages particularly about discrete output devices that are attached to heat-sinks. They have a bad habit of dry jointing also. Good Luck

looked for a free manual on line for you got heaps... but not your exact model. You may be able to cross reference one

No output on main speakers

I have experienced a similar problem with my Sony STR-GX57ES and took it to a certified tech only to find it needed the power supply replaced. I opted to hunt down a compatible power supply but have been unsucessful thus far. That being said I picked up an STR-D665 for next to nothing and found the power supplies to be quite different (you would hope so any, with the ES meaning Elivated Standard and all) but with the D665 working flawlessly I'd rather have something working than nothing. Good luck!
