Usually that is caused by a bad amp IC. Normally on this model, you would just replace the entire main pcb.

Here is the link for the user manual if you need it; http://esupport.sony.com/US/perl/model-documents.pl?mdl=STRDA2000ES®ion_id=1 Check page 54 for details of the error message - it should disappear if the speakers are connected properly and the unit is switched off and on. Check page 17 for speaker connection details, and ensure they are all correct. Check page 19 for details of the factory reset/memory clearing. Hopefully this will clear the error code and let you set the unit up. Hope this helps, please ask again if no luck :)

Protect mean that the speaker wires are touching eachother or that one of your speakers are blown and it is shorting out the receiver.

Do you still have the AVR1500? I have one with a bad tuner--and would be interested in purchasing your for parts. Let me know if you still have it and if you'd be willing to sell it.

Check the speaker connection. One of them has a shortcircuit. Try to disconect all of them and power on the device. See what is happen. If starts corectly check the speaker cable. Conect one by one and power up the receiver after each connection. When you get the error again check the last conected cable. These receivers have a protection system against shortcircuits. That is puting your device in that error.

Protect display on these usually means there is a short in the amp section. Most likely the amp ic itself. Would have to get this repaired before it will turn on correctly.

How do i reset a sony HCD-EC909iP 530w stereo that says "PROTECT" when i plug it in?


Look on the back of the unit to see if you can find a reset button. If not then you may have blown an internal fuse.

Check the speaker wires for shorts, if okay! suspect the audio output ic's, the protection circuit won't come out of standby because there is a short.

SONY HCD LX-50 msg: "Power down to Protect"


Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it '*****'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections at the speaker as a root cause for ntermittent shutdown.
