Marantz sr 5001 turns on but no sound

SOURCE: Audio glitch on Marantz SR-19

It's probably not heat due to the Marantz' large frame and heat-synchs.
This could simply be a mismatch of impedance. The amp is 120w per channel, so make sure the speakers can handle this. Check the impedance (ohms) of the speakers and the amp as well. Clipping can be caused by overpowering the speakers, which could damage the speakers in the long-run.
If this is only from 1 source- (i.e.- Blu-ray player or cable) then it could be digital clipping.. This Marantz can decode 96kHz PCM or normal Dolby Digital & DTS. If this is a Blu-ray it may be streaming 192kHz PCM... (but most likely the Marantz will not even attempt to play that audio)
I hope this helps.

SOURCE: Marantz SR-18 NO Sound No Data error for DSS (Directv) only

You need to check the connection of the lead that carries the audio from the DSS to the amp, move it to one of the other channels ie vcr and see if it can be heard when set to and switched to vcr. Then we know if we are dealing with the Amp or the source..

Change the audio amplifiers IC´s because are on short circuit

SOURCE: marantz sr 4200

This is an indication of some bad solder connections on one of the boards. It could be the power supply board, amp board, or the digital board. I would like to be more specific, but this is not a common problem with those symptoms. Bad solder connection are a common problem and can cause many different unusual symptoms. Unless you have excellent soldering skills, it would be best to let a service center repair this for you. This is a very good receiver and is well worth getting fixed. If you have excellent soldering skills and are willing to take a chance on fixing it yourself you could save yourself some money, but be aware that if you make even one mistake while soldering, you could easily cause much more damage than you started with. Some of the components that may need to be resoldered are surface mounted IC's that are very difficult to resolder and if you have never done this before it is not a good idea to start learning how to solder on such a nice receiver.

Let me know if you need any further help.

SOURCE: no surround modes produce any sound . only have

Not having the ability to look at it on the bench, more than likely your DSP chip is bad. If you have a local repair house that is willing to confirm that is the problem without charging you an arm and a leg, that's your best bet. It is an expensive repair, anywhere between 300 to 500. At that point, I would say to replace the unit. Sorry for the bad news, but that's my "best guess" The only other thing to check would be your "Audio input Settings" Make sure it's either on "Auto" or whichever type you are using. "Digital Coaxial", "Optical", or "Analog" (RCA) hope this helps! If you have any further questions, just post a reply and I can help further. Best of luck!
