Question about Sony STR-DE835 Receiver
I turn my stereo on and about 3 seconds later the display reads Potector. How do I fix this?
I have the same problem but i found a temporary fix! look inside the unit and on the right you will see a little metal thing with fins on it 1 inch by 2 inches. It's on the upright circuit board, the closest plug under that, unplug it and turn your unit on. After the unit turns on it will be normal again, then just plug the wire back in while the unit is turned on. Not sure what the wires are for but I love my stereo and I am too cheap to take it in. Not one single site knew that. I figured it out trial and error! If you turn off the unit and it doesn't turn back on without saying protect,repeat process and just leave it on! There is an onboard diagnosis system on the unit that runs at startup and sets that message, so I think by turning on with that thing unplugged bypasses diagnosis of that part, letting the unit turn on then diagnosis process stops and you can put the wire back on. I totally disassembled my unit looking for problems so I can tell you that if that part is bad that the wire plugs into, it can easily be changed. I am not an electrician of any sort and I completely tore apart and put mine back together. I haven't turned mine back off yet to see if it restarts normally, I've been working on figuring it out for three days so I'll leave it on for awhile and enjoy my music before I try that. Worse comes to worse if it doesn't come on normally I will repeat process and leave it on until i get the replacement part! Enjoy having your music back on!

The most common problem found on FixYa for Audio Video
My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standingsony str-de835 in protector mode - 2_bing.gifimg src="http://i.fixya.net/uploads/images/2_bing.gif" alt="2_bing.gif" class="h_mi" />) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.
