Question about Denon AVR-1905 Receiver

Goes to standby with fast blinking red light after 5 seconds

When I power the receiver on it goes to standby with a fast blinking red light after round 5 seconds. I've tried unplugging everything, powering off, and removing the power plug before trying again, nothing works. It seems like the safety cutoff is doing something, but with nothing plugged in, why would it have a problem?

All of a sudden stopped working and won't turn back on. been 12hrs. when power is pressed, it turns on for 2 seconds and then standby lights blink again and it turns off


This could be caused by a direct short circuit on the speaker outputs. Try disconnecting all the speaker connections at the back of the receiver and then power back on. You can also try a factory reset by holding the surround mode + clear button for 3 seconds.

My sr5004 marantz receiver has gone into standby with the indicator is blinking how do i get ride of it


If the red led is blinking fast (8x/second) the power supply is likely damaged and the unit will need to be serviced. If blinking slow, the most likely cause would be a shorted speaker connection. To help find the cause, unplug everything including the power and speakers. Connect only the power and try to turn the unit on. If the light doesn't blink, you know you have a shorted connection. Power off and connect the inputs and then power back on. If the light is not blinking, you know the problem is with an output connection. Just find the bad connection by process of elimination.

TV won't turn on. flashes a series of 5 red lights instead of turning green


Usually Sony and LG Blinking Codes are the same. Here is what I have.
  • Unit is dead, No blinks - Problem in the standby power section. Might check fuse,
  • Continuous blink once a second, no pausing - No reply from the jungle IC301 (data bus is busy, shorted to ground, or held high), IK video path is defective.
  • One blink - not used for the self-diagnosis
  • Two blinks - B+ over current protection (OCP), unit goes to the standby mode then displays the 2 blink fault. Could be a short in the power supply of any of the circuits.
  • Three blinks - B+ over voltage protection (OVP), unit goes to the standby mode then displays the 3 blink fault. This is also a problem in the power supply circuit,
  • Four blinks - No vertical Deflection (V STOP), Screen goes to a single horizontal line then the video signal muted.
  • Five blinks - AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video. In addition, unit could be in IK blanking, try turning up screen slightly.
  • Six blinks - No Horizontal (H STOP), no raster, goes to the blinking self-diagnosis function immediately.
  • Seven blinks - High voltage shutdown. The high voltage has exceeded 33k and the unit goes immediately into safety shutdown. Check power supply regulation and horizontal circuits.
  • Eight blinks - Problem with the audio (AUDIO), unit goes to standby and blinks the self-diagnosis code.
  • Nine blinks - Panel Module Error or Thermal Error. If it is intermittent 9 blinks, meaning sometimes the TV comes on and other times you get flashing Make sure the regulator is -12 or -13 (negitive).
  • Ten blinks - Check Q8014 and Q8013 for shorts, leakage, or bad solder connections on the " D" board. If the transistors are bad, check R8051 and IC8005, also on the "D" board.

Replaced bulb yesterday worked fine. Today light will not turn on. projector turns on both lights green for 10 seconds, then power goes red and status blinks green for about 5 seconds, then status light...


green green is power on, normal
then it tries to light the lamp, but it can't so the protection circuit comes activated.
you get red and green blinking

Then it goes to standby, red and off.

so something has happened to the lamp, or lamp ballast power supply.
Take the lamp out and check if all is OK with the 2 terminals in the connector, and the leads to the lamp are intact.

Failing that, I would suspect the ballast lamp power unit

AKB circuit (automatic kine bias), the timer/standby indicator blinks for about 30 seconds then goes to the self-diagnosis function. Something is wrong with the video.

When i power on the device, it comes on but goes off about 5 seconds later.


Hi...

1st thing to check is for GOOD speaker connections at both ends
and not mixing A and B speaker wiring.

A Denon is usually a good brand. Might be worth servicing if need be.
