Why is my Marantz sr7500 not working properly?

As soon as the CPU detects one of the three conditions for protection mode the CPU switches off the main relay and thus the primary power side of the main power transformer. There were still problems in the rear surround channel circuit, as I had the amplifier running when I had removed the output transistors.

Is there a problem with my Marantz a / V receiver?

My Marantz SR5005 A/V Receiver: No sound output. This problem arose suddenly while watching TV over DirecTV. No sound regardless of what device I select (DVR, Blue Ray Player, etc.) but the receiver switches everything correctly and the video section works fine.

Why is my Marantz 7008 HDMI not working?

The 7008 had the board replaced, behaved for 6 months, and then had the exact same issues started coming back. I’m convinced it’s bad HDMI boards causing the issue especially since the boards have been replaced and the issues fixed (temporarily).

How often do my Marantz HDMI issues go away?

Most times it just shows up about 10 minutes after I turn on the tv and avr. After the 10 minute period the issues usually goes away. Probably once a week it will show up later on in the day or night. I have changed the video setting from auto to analog, no difference.

What should I do if my Marantz sr5005 receiver is not working?

consider a RESET. A reset is both a test and a try of a fix. As it implies, a reset would force the unit to revert back to factory defaults removing glitches and config errors but would include memories, presets and user preferences. After a reset, the initial setup would have to be performed. If have not been done and should you venture to try:

Can a Marantz arc work on a Samsung TV?

With that, I was able to connect one HDMI from my Sony 4K’s ARC designated port, to the ARC designated output on the Samsung receiver. The TV would then send all the sound to the receiver and it worked flawlessly. Now I am using a premium Marantz receiver, and am trying to do the same thing, but it does not work.

What causes a Marantz amplifier to go into protection mode?

The CPU performs, some checks namely low voltage line and amplifier checks: Over temperature (high heat sink temperature >80C, amplifier running at too much load continuously) Any one of these three conditions will cause the unit to go into protection mode. The unit also had a blown amplifier channel.

How does the Marantz sr8500 AV receiver sound?

And not brute force but purity and composure dominate the sound. SR8500 reproduces the upper band with a somewhat harsh accent, but in a good way – discants are not primitive, both strength and brilliance are felt. The level of sound resolution at the Marantz receiver is average for its price category.
