Check speaker to power bank protection circuit. The circuit is faulty indicating to the power amp that speakers are disconnected that shuts down the amp to protect the unit

Red power light blinking on my denon avr 1907, tried reset procedure, no speakers hooked up now and it still goes from green light to blinking red light and shuts off...Any clues?


This is a protection mode. The receiver protection circuit detects an internal problem like missing power supply voltage or blown channel and shuts down the receiver. You need to bring the unit to a repair facility.

I have dell optiplex GX280 when i press the power button i dont get any display and cpu fan reach to its max speed how can i fix this prob?


May be serious. See if the power light goes amber after power up. I had (have - still siting in my basement) one that did same. Power up, fans sound like 747 taking off. Power light goes amber. This is USUALLY caused by bad capacitors on the mother board. Known GX280 problem going back. If you look on the motherboard, the capacitors should have flat tops and not leaking. If the are rounded or leaking, the MB has probably gone bad.

I obviously can not be 100% sure about this as the unit is not here.

You can google this and see the issues. Here is one such link.

Behringer mixer power goes off after running about 5 0r 10 minutes then power turns on.what is problem with the power supply board


That time lag would indicate a thermal problem.

Likely the power supply is a switching type that has some three terminal regulators after it such as 7805, 7815, 7915.

These have thermal protection in them and one may be shutting down.

Use circuit cooler to isolate the part that is shutting down.

If you power up the amp with the RCAs plugged in, does it go into protection mode.

If you power up the amp with the RCAs plugged in, does the woofer pop?
