Receiver worked last night. I turned it on this morning and it just clicks over and over. Never comes on. I have to unplug it just to make it stop clicking.

SOURCE: Receiver making alot of clicking noises.

I Have a son STR DE 845 and the speakers make a popping sound when it is in DTS mode what is the problem.

Thanks,
Larry

SOURCE: Receiver makes clicking sound when I push power, but does not turn on.

Sounds like a fualty push button - try connecting/soldering on a new one of a different type!

SOURCE: STR-DE475 receiver flashes "PROTECT" when turned on

Protection is usually a sign of overheating or something is wrong at the power amplifier's output.

Theory: Protection is a delay and sometimes an internal test to allow the electronics to stabilize during power up before they are allowed to interact with the speakers. The most common cause of it remaining ON is that a speaker cable pair is shorted. Some isolation is required...

1. Turn the Power OFF.
2. Disconnect each set of the speaker wires that are directly attached to the receiver. Mark them so you remember where each one went. pay special attention to which conductor is on "+" or "POS" and which is on "-", "COM" or "Ground". You may elect to disconnect them one pair at a time if your sytem is complex and you don't want to lose track of where things were.

Turn the Power ON. Is the "Protect" indication gone from the display?
--------------------
If YES, you have a shorted speaker wire or speaker. To isolate the specific cause:

1. Turn the Power OFF.
2. Attach ONE speaker wire pair at a time and test it by turning the Receiver ON. When the "Protect" light returns you have isolated at least one of the cause(s). Disconnect the defective speaker cable and continue isolation of all speaker cables. Visually examine the cable at both ends for frayed wires that could touch each other or contact metal on the receiver or other objects.

To isolate further within the cable/speaker pair - disconnect the speaker end of the cable on the failing path. Try another cable that you know works, or at least one that doesn't cause Protection to stay on.

If you're electrically savvy and have a Digital Volt/Ohm Meter you can troubleshoot the short(s) with it.
-------------------------

If NO, there is probably an internal problem.

Is it solid or does it come on after the Receiver has been ON awhile.
It could be overheating.
Is the unit hot to the touch?
Is there a cooling device (fan)?
Is it stopped or clogged with dust?
Is there adequate ventilation around the unit for air to flow?
Clean any ventilation slots on the top and bottom of the unit.
Avoid stacking components that produce heat under an amplifier or receiver. Their heat rises. Also keep them away from other heat sources like like home heating vents and radiators.

Problem solid and NOT related to the speakers or heat: internal malfunction.

Let me know.

SOURCE: My receiver will not power on anymore. I think it

It may have a reset button on the rear panel.

SOURCE: As soon as I plug the receiver in, it clicks on and off

might be a dry joint on one of the solder joints on the relay/driver transistor that controls the speaker time delay, also it could be a faulty zener diode that controls/limits voltage to the relay coil, this can short circuit the relay and iturn the small snadby current present in its powersupply, get a service guy to look at it
