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: If the receiver is played back at maximum volume level it may enter the protect mode. Maximum volume listening will cause the receiver to run very 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: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
  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.

I get an unlock display when I change to vid2 input. How can I unlock the input? Thanks


I had this exact issue.
I was using the digital 2 input for sound. (Toslink cable from my cpu).

It seems I inadvertantly muted the sound on the pc, and this caused the "unlock" message with the L-R speakers flashing on the display.

I restarted my pc; and then unmuted the sound.
3 seconds later; the L-R stopped flashing and I now have sound on Vid2.

Front panel is locked and don't know how to unlock it.


1) turn off the main power button (not the big LED stanby button)
2) press and hold "input mode" and "speakers" button simultaneously
3) press and hold the main power button for seconds, until display flashes.
4) release all those buttons. The AVR is already reset to factory mode.

My samsung phone c170 was loked plz. give me unlock coad


As you have not specified in particular what is the unlock code required for you, i am giving the ways to unlock all the codes

NETWORK UNLOCK CODE:

You can unlock it by flashing your mobile if your mobile is a CDMA mobile...
The procedure for flashing your mobile is in the link below
http://hubpages.com/hub/How-to-Flash-your-cell-phone
It has an video explanation.

If your mobile is not an CDMA mobile , you can get the network unlock code(NUC) by just contacting the current network provider customer care department.It is free of cost.

The restriction code can be got from your old service provider..This restriction code is kept to prevent someone who stole the mobile from using it with another provider...

They will have a security check done with your date of birth etc..to verify whether you are the exact owner of the phone..

After that they will provide you the restriction code to unlock it and use it with another service provider..

It is all free of cost do not pay anyone for this seeing some advertisement over internet . That is all fake ads.

The above procedure works and you can verify that by seeing the rating of an happy customer here..

PUK CODE:

PUK code can be given only by your service provider which is specific for each and every mobile number.
Contact your sim customer care department over phone. Its free of cost to get the pin or puk no. If you cant contact through your phone get some other phone and contact them.
Go to the nearest service outlet of your service provider they can also help you.
There is no other go than the above procedure only your service provider can give it nobody else in this world nor any software.
Go to the below link and you can confirm that the above procedure works and there is a testimonial given by the customer too. http://www.fixya.com/support/t3582685-phome_lg_ke670_put_security_code_phone


PIN CODE:

HI If you are asking for pin contact your service provider , he will give you a default pin .

If you try pin more than few predefined no of times your phone will ask PUK code which can also be given only by your service provider which is specific for each and every mobile number . Do not try PUK(new pin code) code many times or else your sim will be blocked and you will need a new sim.

Contact your sim customer care department over phone. Its free of cost to get the pin or puk no.

Go to the nearest service outlet of your service provider they can also help you.

There is no other go than the above procedure only your service provider can give it nobody else in this world nor any software.

If it is lost nothing can be done. You need to flash your mobile at an authorized service center which will reset the mobile memory and also all the data inside the mobile will be lost.

Denon DRA-37 Receiver-Remote lock on. Need to unlock.


Refer to the "Initialization of the Microprocessor" section of the manual (page 16 of the PDF version of the manual).
1) Turn the unit OFF using the On/Off switch (not the standby switch).
2) Depress both the Speaker A and B switches, and turn the Power ON.
3) The entire display should flash at 1-second intervals. The microprocessor should be reset, and the remote should be unlocked.

No sound in hdmi mode unlock flashes on display I get sound in cd


Its asking your permission to unlock the setup menu. When you hit setup, and it says "unlock," you have to hit one of the navigation arrows on the remote control. Once you have unlocked the menu, you can assign the audio to that HDMI input.
