Arcam avr 300 keeps switching off intermitently, and the red standby light flashes.

Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

Hi
Are you familiar with electronics?
If and/or when the red led light is flashing it means the device is in protection mode.
1: check voltage regulators 5v and 12v which are the important parts to keep the device operating.
2: if there is a short circuit on the power amp, meaning the power output of the receiver.
3: check output Transistors.
Hope this will help or you can give these to a technician that can help you.
Good Luck

if the receiver does not power on from standby there is a problem like bad power supply or even bad macroprocessor. You need to bring it to a service center for diagnosing. 10-years old receiver, maybe better to buy new one.

ok my denon avr 1804 was jamming and it shut off on standby red light flashing comes on then goes back off what is wrong ?????

Actually, it doesn't have ANY digital outputs. Just what do you require one for? Name specific models and functions when replying.

Do you think the TV NEEDS optical audio from the receiver? Maybe the TV could survive on just analog audio from the video source, while the GOOD audio goes to the ARCAM since the ARCAM is going to do the hard work of managing and driving the REAL speakers.

hi,
I have the service manual of ARCAM AVR 200 with me. send me a mail on my mail id. I will send u the service manual. its a large file having a size of 4.8 mb. I can sent it through fixya.

Check the standby transformer T752 first. if its primary winding is short the this problem can occur.
ok

Hi,
Can you, or can someone you know, check for DC voltage on the speaker terminals when the amp is on, but not playing? Ideally, the meter should read 0mV with no signal, and certainly less than +/- 10mV. Anything over +/- 30mV is worth having checked out, especially if it changes as you turn the volume knob with no signal applied.

You're drawing too much power from it. Sounds like maybe your sub is hooked up wrong, double check that.

seeing that its bleenking red it letting you know that the main capassitor to the transformer has blown and if you keep it pluged in it will in a short time allow the transformer to smoke and it can overheat and catch on fire.....NO GOOD. Its 1 of Denon's problem's....I see it quit often.
it will cost around 300.00 to fix.
Please let me know if I can Take it of your hands for the need of the left channel on another one.

By the way LET ME KNOW I do have 2 new Denon's an Onkyo and a Harmon Kardon I can give you at a cheeper price around 369.95 for a AVR788
Email or call me and I will give you 45.00 off ...OK...PayPal

I mwas gonna suggest that you need the speakers attached but you stated later that it did the same thing with the speakers attached. The unit switching off after it checks its self is NOT a normal thing. TAKE IT BACK BEFORE ITS TOO LATE!! GOOD lUCK
