if your preferring to protect light your either, pushing to much power, or a wire could be touching along the line. Check all your wiring even the ones behind the receiver that could be your problem

SOURCE: My SONY STR-DE835 receiver amplifier is showing

These models are known for this issue.
I've had my share in the shop here.
Disconnect all speakers,turn speakers off, try headphones only
If it still persists then there is either :
1. power supply capacitors gone bad or 2. The thermal fuse in the transformer is open.
A tech can very easily find out if the thermal fuse is open by checking the primary of the transformer
if the plastic is shrinking away from the power supply capacitors then they've gone bad

You may have the speakers incorrectly connected or the speakers you are using have an impedence that is too low for the amp to support.

Flashing word "Protector" shows up and the sound stop on my Sony da555es receiver. I have to turn off the unit several times before the sound stays normal.


Usually a protect fault will indicate a bad transistor in the amplification section. I suspect that the control circuit is sensing a fluctuation in the power supply and going in to protect mode. (assuming that the protect circuit itself is working properly) If a voltage is too high the unit will go in to protect mode to prevent damage to the speakers and the rest of the unit. I would take the unit in to a local repair shop and get a estimate of repair charges. Expect a 60 to 80 dollar repair charge depending on how many parts need to be replaced and what the repair labor rate is in your area.

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.

Have a da555es stereo receiver. Fuses blow as soon as you plug it in to wall socket. Receiver is approx 10 yrs old and just started doing this. Any ideas?


If fuses blow out imediatelly its a sign that its something wrong in the imput area eg the power pcb or transformer pcb. try to see is there in its supply some electronical parts broken or some bad wire isolation.

Same thing


normally this happens when there is too high of an audio output. To fix this, change the system to tuner and turn down the volume (if it allows you to) and then unplug the system. Plug back in and it should work. If that doesnt work, try unplugging for 15 min to allow it to reset.

PROTECTOR (FAN) error message - what next?


Look inside the unit. There is a fuse you can replace in the rightmost front of the unit. 125v 3.25A, I believe.
