This is often caused by shorted speaker wiring or a shorted speaker voice coil.

SOURCE: "Protect" Flashing

In all likelyhood, one or more output transistors have failed. Please confirm your model as STR-DE335 and I'll post the probable parts that need to be checked.

Don't forget to disconnect your sources also(dvd,satellite,vcr,cd player,etc) they could have a short in any of them causing receiver to go into protect,If still flashing "protect" your Sony could have an internal short of it's own, or caused by an external short previously mentioned. Good luck !

SOURCE: KENWOOD DECK FLASHING (PROTECT)

protect mode means some speaker wires somewhere in the car are grounded out or are crossed... find the short and it will fix the problem. try testing all of the speakers one by one from the wiring harness... you'll find the problem. Good luck.

SOURCE: Sony STR-D665 receiver display flashes "PROTECT"

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: How do I get out

This is what it says int he owners manual.

PROTECT (Blink): The speaker wire has a short-circuit or touches the chassis of the vehicle, and then the protection function is activated. Wire or insulate the speaker cable properly and press the reset button. If the "PROTECT" code does not disappear consult your nearest service center.

I have a Sony PDX-10 and it's giving me two blinking yellow symbols (underlinded triangle and tape with line through it) when I fire it up loaded with a tape. Tried changing with tapes that work fine in...


Hello,
Looking at PDX 10 User Manual Page 232

Your description -

Under lined Triangle

Cassette Ejection needed
Slow Flashing: The Write protect tab exposed

Fast Flashing: Moisture Condensation
Cassette out of tape
Self diagnosis display function activated


Sounds like the diagnosis function maybe your best shot......
Check displayed error codes in viewfinder on Page 231 of the User Manual or let me know if you dont have copy of them.

Tape Symbol Flashing:

Tape near end
No cassette inserted
The write protect tab exposed.

I think this is basically telling you the loading mechanism has a problem, the viewfinder is displaying an error code indicating the nature of the fault..... IF error Code is : E61:........ or E62........ (dots indicate extra numbers) these MUST be referred to Sony Service Centre.

Hope this may help

Flashing message on my reciever


PROTECT, PROTECTOR or the letter P is flashing in the display of the A/V receiver. Solution
sp.gif sp.gif Follow the steps below to troubleshoot if the word PROTECT or PROTECTOR is flashing on the A/V receivers display.
  1. Check the speaker wires and speakers for proper connections.
  2. Reduce the volume level. IMPORTANT: Ifthe receiver is played back at maximum volume level it may enter theprotect mode. Maximum volume listening will cause the receiver to runvery hot and may drain the output capacitors.
  3. Disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the receiver has proper ventilation to keep it from overheating.
  5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Somereceivers provide compatibility with the higher sampling frequenciesthrough alternate connections. Consult the owners manual for specificinformation.
  6. Unplug the AC power cord for about 1 to 2 hours to reset the output transformers.
If the issue is still unresolved, service may be required. The Sony® eService Web site at http://eservice.sony.com/ can assist you in obtaining service from a Sony Service Center or locating a Sony Authorized Servicer.
