Protector message i have a sony str-de825 and is giving me a protector message, how do i reset it and make it work again? thanks

In most cases the output is faulty as the MOSFET's shorts and so the drive board has to be changed. This is an expensive replacement and many when the estimation is done opt out. In some cases the protection is due to the fault of the protect circuit, failure of transistors or passive components.
Since most of the board are hard to access , the work estimation is high as boards are replaced.

Please see the following for an explanation:

yes either buy the sony dock for mp3's or go to Radio shack and buy the adapter that goes from a headphone jack to a red/white RCA plug get the gold tipped version and just use an open interface on the back phono, tape, whatever you have open.

This usually means a short in the wires, or you have very poor ventilation for your system. You dont normally see this unless the volume is extraordinarily loud or the unit is overheating. I hope this gives you a few things to look at or try.

sony are pretty rubbish at offering patent parts, my suggestion as poor as it is would be to approach sony for this part they will recommend a retail outlet that can supply it

there could be a short in one of the connections or your power supply could be fried also ive seen some models with internal fuses that have blown

very basically try swapping over the speaker cables, if this doesnt work i suspect you are in need of a new ouput i.c. these can go if the speaker wires are touched together, unless there is a protection circuit.

Cambiale los IC de audio que esten dañados por eso se pone la leyenda protected.

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 :)
