Got this from another link it may help, I haven't tried it....

The protector indication is always a sign of power problems. The most common of which is the loss of the output transistors in one or all of the audio output amplifiers. These devices go whenever they are overdriven, get too hot or have accidental shorts placed across the speaker terminals.

They are easy to replace if you have soldering skills and know how to identify them and ask the counter person at the local electronic parts store how to match for a replacement.

The equivelant replacement must be the same gender (npn or pnp), same physical package so it will mount on the heat sink, with higher voltage ratings than the original and current. If you can get the SOA or Safe Operating Area spec from the originals, the replacements should be a little higher if possible; that way they won't go again so soon.

I donot have the schematic or service manual for this unit, but you can calculate all the output parameters for the device by knowing the power output ratings of the amplifier into an 8 ohm load. P=E times I or V squared/Rload.

Let me know if I can guide you along the way.

SOURCE: Sony STR K840P, protect mode is flashing,no

This is a classic problem. One of your speakers is miss wired and or your speaker wires positive and negitive leads are touching. Check all connections from the back of the reciever to the back of the speakers to make sure your positive and negatives are correct and that none of the wiring is crossed or touching one another.

The most common problem found on FixYa for Audio Video 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 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 standing speakers) 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.

SOURCE: No audio sound, Reciver going to protection mode

If you bought the extended warranty, you need to go where you purchased it and they can look it up on their computer system. If it's out of warranty, the repair cost is debatable. Between 125-175 average. 50% of the cost.

I have sony radio.but now is display flashing protector and I cant play anything ,how I can solve this plobleme


Disconnect the receiver for at least 30 seconds..Disconnect all speakers.inspdct each speaker cable and make sure all wires are twisted tight.one little wire sticking out can make bad contact with unit.turn on reciver..hook up front speaker wires and then one at a time hook the rest up.hooking them up one at a time will show and tell if you have a bad external speaker or wire problem causing your receiver to go into surgery protection mode.thats why it is important to twist your speakers cords up properly inspecting each one.
You can run your receiver a fourth of max volume for 20-30 minutes to warm up checking each connection.

No sound. It flashes protect.


Your device has went into protection mode, an internal malfunction causes it to shut down in order to protect itself.
Somtimes a physical reset will help.
Turn of and unplug device fro a couple of hours

My Sony Wega Trinitron KV-32HS20 does not tun on and the standby light flashes 4 times. I can hear the sound but no picture and the it turns off automatically after a few seconds.


This is a tip I got from a tech bulletin.

IC600 output pins 14, 15, 16, all have aprox 130v (all should be higher) until relay clicks
then they drop off. 200v line goes up to 50v, 135 goes up to 40v.
Checked D611 (135v rectifier) it was fine. Checked D615 (It's labeled D601 on the board)
it was shorted. (D615 is the 19v rectifier for the Audio B+) Removed D615 set power up
and has good picture with no sound.

As soon as i turn on my STR-SE391 reciver the protection is on


It is unlikely that the pushing of buttons caused the problem. The protect flashing means that a problem was detected and the system has shutdown to prevent further damage. The most common cause of this is a failure of the output transistors. Plan on a parts cost between $20-$40 for this repair.

My receiver is in protect mode.


The units in the protect mode because the Microprocessor detects a large current being drawn by the amp. section of the reciver. This is a solid state unit and there are no user replaceable parts inside this unit. Unless you know how to trouble shoot sloid state devices then you should seek a pro to assist you with this repair. GOOD LUCK
