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!

    I'm not sure I see the metal fins you mention. Can you provide more detail? Thanks.

The most common problem found on FixYa for Audio Videosony str-de835 in protector mode - 2_bing.gif Receiver's is:

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 wire2_bing.gif. 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.

Make sure none of the speaker wires are touching each other. If they are, it will short out the stereo which triggers protection mode and cuts out all of the sound.

The receiver will be on for a while 5mins.or so, then it will make this loud sound as it goes into protector mode...what is this and how do I fix this. I have it connected to the TV, DVD Player, CD, VHS...


you have speaker wires that are shorting out. unhook all the wires and ohm them out. Find out which one is shorting. I've had this problem before. It's fine until you turn it up, Then the receiver turns off and goes into protect mode. It's just a short in the wiring,.

My SONY STR-DE835 receiver amplifier is showing PROTECTOR on the digital readout.Anybody know what that means.


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

My STR-DE835 receiver will not stay powered on


Most likely bad output transistors and a couple of resistors. mp1620 and mn2488 are the part #s for the transistors. If you take it to a repair shop you are looking at spending $100-$130

My reciever turns itself off


You most likey have a wire short on your center or rear surround speakers. The wire short will be between the + and - points of the speaker wire.

To find the problem speaker, disconnect one of the 3 speakers at a time from the back of the sony and see if the problem goes away. Once you identified the offending speaker, check both the sony side and speaker side for the short. The small wire strands are hard to see and it only takes one to trip the protection mode, so look carefully.

This message indicates that a problem was detected in the amp. In order to prevent any further damage to the amp or the speakers, the outputs are turned off. Does the receiver show this at all times now?
