How to Troubleshoot a Marantz SR7001

Updated July 20, 2017

The Marantz SR7001 home theatre surround sound receiver is an impressive piece of audio gear. It can fill even the most challenging spaces with quality sound while switching between a plethora of audio and video sources. It's also built to last. Despite its build quality, problems may arise. Listed below are a few steps you can take to isolate the problem and be back on the road to home theatre bliss in no time.

It is best to start by determining whether the problem is with the Marantz or one of the various sources connected to it. If possible, bypass the receiver altogether and test source components (DVD, Cable or Satellite box, etc.) directly via the television. If the problem continues, even with the receiver out of the loop, you know the SR7001 is not the culprit.

If your receiver is flashing "PROTECT" on its display, you have a crossed speaker wire. This is a common problem. Be sure the positive and negative speaker wires are not touching behind the receiver or at the speaker terminals. One strand of wire crossing at any point can cause the receiver to enter "PROTECT" mode. After checking all your wire connections, turn your receiver back on. If the wires are properly separated, the problem should be fixed.

If your SR7001 will not power on at all, there are a couple options. If the red standby light is not illuminated, you most likely have a nonfunctional power supply. Check the power outlet and cord for damage and make sure the outlet is live. If the standby light is red and blinking quickly, try resetting the receiver. Unplug it for 10-15 minutes and then plug it back in while holding down the main power button. This fixes some minor problems. If the standby light continues to flash, you will need to have the unit serviced.
