Marantz sr7200 sound cuts out after 5minutes,not completely, just sporadically. No excessive heat or anything- Is there a fix for this? I have a Marantz SR 5000 with a similar problem. The sounds cuts off for a few seconds or a few minutes.I can not seem to find a pattern or a fix!

Most likley, if I'm right, you have heard some staitcy, crackly noises, accompanied with this failure. If so, the problem is without a doubt on the D.S.P. board, witch is the one with the optical jacks on it, The culprits would then be I.C. 719 & I.C. 720. This is a common problem with this model, and the sr6200 & 5200 as well. A low tech method to confirm this is to touch IC 720 (the smaller one) while it's on. If you can keep your fingertip on it for at least ten seconds, it's ok, and the problem is elsewhere. If not, (IT WILL BE VERY HOT) the the board must be removed (27 screws from left to right) and replace BOTH IC719 & IC720.

    I have the same problem whith a sr6200 and I have tried this test you explain. In my case the IC720 has a normal temperature, but the IC719 really burns!. You can't keep your finger on it for more than a second, so I guess I have to replace both also, don't I?

    Thank you very much.

I have a marantaz sr7200 and all the audio outputs have quit working. What might be the problem?


Sounds to me like something fried. If no output are working, but the rest seems to be. Are you talking like digital audio out, or speaker terminals. Could be an internal relay. or single audio plugin board. Not sure how it's set up on the inside.

I have a marantz sr7200 receiver and i am unable to get sound when its in DSS mode. The sound works in dvd and tuner modes.


In the setup menu, did you set up the input assignments for DSS to be the correct digital input or analog?

I have a Marantz SR7200. I have been using for a long time with 6ch stereo with no problem. Suddenly, it starts to make a lot of noise on front speakers in any mode. It just stops this noise when source...


Hello Sergio.

Sounds like a bare wire (speaker wire) most probably is touching your SR's metal body.

Remove all speaker cables, re-terminate them clean (cut, trim, and twist again) and then re-plug them in to the binding posts.

When you go puredirect, it overcoms some filtering circuits of the board and this should be the reason why it stops.

Try that & advise.

UK, I have a sr7200 but no remote! Are there any compatable ones out there? I have been quoted £250.00 for a replacement


I bought a RC3200 programmable remote after my dog chewed the origional unit. £30 off ebay, works a great. It comes preprogrammed for all Marantz units. Only problem is that it is a bit hard on batteries.

This is the problem with computerized stereo's. The old analog stuff we could fix forever, but many of these digital problems, only the maker has the tools to repair. Feel fortunate that yours will even offer you support, even though expensive.
Good luck.
