20 Most Recent Marantz SR-7200 Receiver - Page 2 Questions & Answers

if it's a blown amp channel, might cost around $150 to repair

If the noise is not present in Direct or Pure Direct mode it is definitely associated with digital circuits.
I assume, the unit is not under warranty. Open it and inspect connections to and from digital board. If this does not help it might be faulty connection on the board and it is better leaveing this to a specialist. I hope you did not fiddle with the service menu?!

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.

Register and download the manual for free at retrevo.com http://www.retrevo.com/support/Marantz-SR7200-Receivers-manual/id/511dj782/t/2/ Simply run a composite video (RCA) cable to the TV.

Have you changed any connections behind the CAV recently? This happened to an associate of mine once and it just turned out to be something simple. This may or may not be the situation in your case. Check to make sure your source audio cables are connected to the correct source number that you assigned in the programming (Ex. AM/FM Tuner = Source 1). Also make sure your audio cable is connected to Source 1 IN (and not the "OUT").

Narrow down the source of the problem:

Make sure the keypad you are using to test the CAV is not in "Mute" mode. Press the "Pause" button to engage/disengage from mute.

To further troubleshoot your issue if the above is not the case you want to use a device (such as an ipod tthat you are sure the audio output is working using a stereo mini to red and white rca cable) and plug into each source input (one at a time) behind the Cav then monitor that source# on the keypad to see if you hear the ipod on any of the sources. If you hear the ipod playing on some sources and not others it obviously means some of your source inputs are having problems and the unit needs to be shipped to Russound for repair.


Make sure the front of the Cav6.6 has the proper colored lights lit up. When no keypads are on the zone should show red, when a keypad is off the color should be green for that zone, if there is a short circuit with the speaker wire the CAV might be in protection mode and the color might show orange.

Hope this helps.

Get the manual, make sure your speakers are hooked up right, go through the setup and get back.

Hand it in for repair.

Bad capacitor or blown power supply.

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.

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.

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.
