What does a trigger switch do on a marantz sr5004 receiver

SOURCE: I have a Marantz SR5004 AV Surround Receiver.

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

To really help you would require a bit more detail. HDMI is the video part of the signal - the audio part may require additional cables. Also, source material may play a role. I'd start by seeing if you have some audio outputs from whatever your source is and connecting those to the Marantz. Beyond that, I'd need more info to be sure I was giving decent advice.

SOURCE: my marantz SR5004 is cutting

Hi,

When you say cutting off, do you mean just the sound or the power to the unit altogether?
If you mean, power to the unit goes out - this is a bad news.It sounds like a power supply issue to me. I would have the transformer leads checked for cold/ bad solder joints, and also the filter caps and power switch tested for shorts or open circuit respectively.
Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!
