Sounds like you system is set up to only provide output current when not charging via the array... its common... shut off or disconnect panels and your problem is solved but the batteries won't be receiving any charge obviously... this set up is used when the systemhas nothing to limit or control the current produced from the arrays/panels from going directly to the attached output devices. This is typical in small pv systems.

I have a old denon avr-1804. try to switch on power but can not. just appear a main power red light flashed rapidlly. please tell me why?


Greetings
the red flashing LED is that the Device is in protection mode.
the internal power supply . +15 volts and -15 volts are defected you need to be replace it ... Regulators 7915 and 7815 .... these you should change , might also need to check capacitors .
these are common defects for Denon . AVR units.
Good Luck
Hope this helps

Receiver will not operate. when powered on red light flashes, menu displays, than thee is a loud click and the red light keeps flashing. tried the reset and it still does not work.


This sounds like the unit is going in to protect mode. See the link below for further information. Specifically to your unit, we need to know the model number. Also, try disconnecting the speaker cables completely and try again. Update this with how the unit reacts. If the unit powers up fine, then there is a problem with either the wiring to the speakers or the speakers themselves.

Please keep us posted.

Thanks,
Dan

Shuts off then red light indicator flashes, disconnected all speakers but still wont work


Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.

Power Button Flashing Red


Try unplugging the entire unit and letting it sit for 5 minutes. See if this helps. If not, you need to do a complete reboot, which will cause you to lose your settings, but will probably solve your problem. To do a complete reboot, you will need to hold down two of the front bottons on the front panel. I'm not sure which, so either consult your manual or see other posts here which describe the reboot process for Denons. Hope this helps.

Denon DRA 395 flashing red power light


Needs to be reset or fuse blown. Take to repair shop, cover has to be taken off and fuse replaced. You could fix it yourself but the warranty won't be honored. Do it yourself electronic shop should have a replacement fuse, may have to be soldered in place. Repair shop, should cost around $30.00 to $45.00 to fix, price of fuse $4.00 to $6.00. Your choice.

No power,red power lights keeps flashing.


I had the same problem with the 47" version. I called the Sears technician who tried for more than an hour to fix the problem, even calling Panasonic. Final solution: a board repair for $550. Now I have a plasma and a big desk.
