Power button light keeps flashing and sound gos my marantz sr4001b

Register and download the manual for free at

Page 48: See the note at the lower right.

After "PROTECT" appears on the unit's display, the standby indicator may start flashing. if it does, there is a problem in the unit or the connection. If this problem reoccurs even when power is activated from the remote control unit, call for servicing.

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Check for loose speaker connections as a root cause for intermittent shutdown.

I want to connect my bravia lcd to my marantz sr770 i can only get two chanel sound from my two front spearker i cant get the surround working

Let's break this into little pieces. Disregarding the TV, does the Marantz otherwise provide multichannel sound?

How is the TV-related audio getting into the Marantz? Analog RCA yields only 2-channel audio.

Two front speakers are only capable of two channel sound.

My Marantz sr 4001 receiver has no output. Is

There is no fuses for the speakers. Check setup. If the receiver has 7.1 channel input try to connect a source there so you can check output (amp) section and the speakers.

I have a Marantz SR5004 AV Surround Receiver. There is an HDMI cable from the cable box to the Marantz and another from the Marantz to a Samsung HDTV. Everything is fine when the cable box is set to an HD...

Hello First off i would determine if the same thing happens when the cable box is connected directly to the TV with the hdmi cable.

If the picture goes out get a new box from your cable company.

If it works fine then its time to call Marantz

My Denon avr 4310 does a similar thing and after a lot of research it seems that the problem is with how digital signals are sent through the HDMI cable and how the control board of your receiver processes those signals.

Here what I mean

HDMI is meant to simplify connections by transmitting video, audio and CONTROL signals through 1 cable.

The problem becomes when you introduce a "middleman" in this case your receiver the control signal doesn't always get interpreted correctly.

My TV has the capability to "turn off" the "control" signal coming through the cable if yours does try that first (i have a sharp 52" led) this solved some of the issues.

My receiver has the capability to accept different inputs and merge them so here is how I get around the problem.

1. I use HDMI for video signal but also use the optical for audio this allows me to send the "complete" hdmi signal through the receiver and to the TV this complicates things but also allows you to get audio through your tv speakers so if you want to watch something late at night you aren't waking people up when the receiver gets loud. This stopped things like the video flickering or turning off.

You will have to play with your menu's to see if you can do this on your unit.

How to fix this easily? Dump HDMI and use component (red, blue green RCA's) for video yes its still HD and yes you will have to run audio separately. but it eliminates all the digital processing issues that receiver manufacturers haven't worked out.

I was pretty upset when I spent $1500 for my Denon receiver and Denon then told me that HDMI doesn't always make anything better.

Hope that helps

Playstation 3

I assume that the Marantz has an Optical lead input. If so you should connect an digital optical lead directly between the PS3 and the Marantz receiver for the sound while keeping the HDMI lead to the projector for the picture. You will need to configure the PS3 to be outputting the sound to the optical output (done through the settings menu).
