Dear all,
When I switch on my Marantz SR 7200 A/v receiver, it comes on and then immediately switches itself back to standby. Please tell me what to do...This thing cost alot of money and I feel cheated that I should lose it just like that.
Sincerely
Gladys
i have a Marantz SR 7200, It shuts off after 9 minutes after turning it on.
the standby red light remains on. I have tried removing all connections to see if it would eliminate this problem, this shut off. I have even pluged thr sr7200 into a different outlet in another room, i dont think the house wiring
is at fault. Any ideas?i have a Marantz SR 7200, It shuts off after 9 minutes after turning it on.

I turn the amp on and it goes on for approximately 4 sec. and then switches to standby. It smelled like plastic for awhile there. I turn the amp on and it goes on for approximately 4 sec. and then switches to standby. It smelled like plastic for awhile there.

It is likely that the PA stage has developed an offset voltage in the output stage. The faulty amplifier channel can be found by progressively disconnecting the collectors of the of the power transistors until the protection fault disappears. Once the faulty channel is found the the cause of the offset has to be traced to the faulty transistor or resistor. Don't forget that if you can smell smoke or burning then there are likely to be components(esp transistors) that have been damaged by the fault. I had a Luxman unit that destroyed 5 transistors in the output stage that was due to an open .5W resistor in the driver stage. Good luck.

If you don't use the remote control is it okay? If so, tear apart your remote control, use a Q-tip to clean all the lines in the circuit board where the rubber contacts touch. Then make sure that the rubber buttons don't have any 'gunk' on them that are making them stick. Clean the rubber pad with a qtip with dishsoap. Dry well, put back together and see if she works. Report back on your success. Good luck.
I had the same problem on my 7200 until I realized that the display comes up on the television screen. I carefully followed the set up required from the manual. I got the Manual online at Marantz.com. I have a cable hook up so I connected the video cable out from the box to the Video in source on the 7200 and monitor out to my Television. I then pressed the Amp button to get the remote to Amp mode. I then pressed the OK button that is in the center of the four direction buttons and the menu displayed itself on the screen . I hope this helps. ercble
Most often it is due to improper speaker loading. In other words,
it needs to have from 4 to 8 ohms speaker load and you wired your
speakers in parallel when they should have been wired in series.
What would have been an 8 ohm speaker load in series, turns into a 2
ohm load when in parallel. And with dual voice coil speakers you
just compound the problem. And don't even get me started on
bridged outputs.
Anyway that is what usually causes an amp to fry. Good luck.
Press AMP then OK on your remote. If the menue does not appear press 9 on the remote. You must have your monitor connected through composit Monitor Out or S-VHS. Also check your multiroom settings. Maybe your OSD signal is diverted through to other room. I do not have SR-7200 any more, unfortunately.
DSP (Digital Signal Processing) Board is probably defective or has Poor solder Connection on one of the Ic's on that board. Board cannot be Obtained from Marantz. Must be troubleshot at component Level and requires a very knowledgable tech to repair it. I have done a few of these in the past and usually charge $50 to Evaluate and Give estimate.
