Be sure there is room around your receiver to breathe. Be sure the fan is working. Is this after it has operated for a while? Try turning off the receiver when not using it.

SONY STR-DE445 UNLOCK CODE


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.

My receiver turns on .. but the amp doesn't .. and the screen flashes "protect" for some reason.. and all other buttons are non responsive.. can you help me?


If PROTECT , PROTECTOR or a P is flashing in the display of the A/V receiver, there may be an incorrect connection or an improper setting. Try following these steps to resolve this issue:

NOTE: Because each of these steps represents a possible solution to this issue, check the A/V receiver status after completing each step.

  1. Check the speakers and speaker wires for proper connections.
  2. Reduce the volume level.

    IMPORTANT: If the A/V receiver is used at maximum volume level, it may enter the PROTECT mode. Maximum volume listening will cause the A/V receiver to run very hot and may drain the output capacitors.

  3. If applicable to your model, disable the surround sound option if both the A and B speakers are being used simultaneously.
  4. Ensure the top of the A/V 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 A/V 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 approximately 1 to 2 hours to reset the output transformers.

If the issue is still unresolved, service may be required.

No sound from speakers


This is caused by the Thermal protection device inside.

First Unplug the Reciever, let it cool for about 15-30 Min and then
Check all speaker wires to make sure they are in good condition,
no fraying wires or loose .

Plug in the reciever, make sure there is nothing on top of it,
(also do not have a shelf directly over it, you need a good 8" of
clearance above it for adequate ventilation..

Now push and hold the Reset button on the left side of the front panel
and see if this restores it.

Another thing to try is, get a can of compressed air for computers and
try blowing out the dust thru the vents on top and sides of the case,
Note ** (Do not open the unit to do this)

Frigidaire FDB635RBB heat wash/heat rinse


Most DW today take a minimum of 90 minutes. Run the hot water from the sink until it gets hot, then start the DW, this will shorted the first wash cycle. It is not uncommon for the DW to run 2hrs or more based upon the water temperature entering the DW and the soil level of the items in the DW.

Technics SA-DX940


Ratnesh, I have this same receiver and the fan only comes on at certain volume levels. Unfortunately I now live in an apartment and can very rarely listen to it that loud. I had the same problem for a little while until I thought about moving the receiver to the lowest shelf with nothing on top of it. This seems to have worked so far although it does still get quite warm. Good luck!

Technics receiver SA AX540 overheating


is the fan turning on? many models like these have a cooling system (fan) that kicks up when the volume is turned to a certain level. if your fan has never been on, then chances are some of your soldering points have shifted or gotten a little messed up over time from the heating/cooling effect. this model runs extremely hot especially right where the vent is on the top of the cabinet. make sure that it is not in a shelf or enclosed area. dont stack other items on top of it. use an external device to control the volume so that you can have the receiver volume at a fixed level where the fan will turn on. if your sound still doesnt work, you should consider buying a new receiver or try your local craigslists forum. make sure if you buy a new one, that it is a more expensive model from a brand like sony and check the model online for known problems. stores like best buy offer extended warranties on most of their products which are very wise investments. good luck sinbad
