Question about Sony STR-DE425 Receiver
Anyone have any suggestions on how to fix a broken power switch on the STR DE725? Does Sony still sell them? This receiver still works great, but for a five cent piece of plastic that is broken.
My sony used to do that to umm cant remember the model but yeh i could play it at low volume but as soon as i turned it up it would start clicking and telling me to turn of the power...
I resolved it by checking every cord connected to it, it turned out that because I connected two speaker cables together i didnt seal it properly and they were touching this was making it go into protetion mode.

Protet mode is a special diagnostic mode that starts when a fault is detected.
When in protection mode the unit is prevented from starting by protection circuit, so to prevent further damage.
Check the speakers and speakers wiring, a contact in speaker wires, or faulty speakers can send the unit in protection.
Try unplugging power cable for one hour or so. then connect cable back and see if you get rid of protect state. Sometimes accumulation of electrostatic charges inside circuit capacitors can kick in protect mode. In that case unplugging the unit from main for some times can get rid of electrostatic charges, and reset circuits by draining power completely.
If that was the problem, you will not get Protect when plugging back power cable.
If you do all the above and still get Protect, then there is a real fault.
In that case the unit may be disassembled and tested to find the fault.
If that is the case I suggest contacting the manufacturer at the number listed on the owners manual, or asking a quote on repair to a local technician.
