Hi Guys,
Recently picked up a Marantz SR5007 Receiver and it was working fine but I reached behind to plug in a network cable while it was on and knocked the HDMI monitor cable, the display dropped in and out a few times then dropped out completely. Since then there is no sound or video from any input or output.
I have found a poor-quality service manual online and done a lot of troubleshooting, its more than likely a problem component on the HDMI board which drives the whole unit but these are almost impossible to find and I am hopeful that its repairable.
Voltage supply is OK, voltage supply to and from the HDMI ports are OK, the analogue inputs seems responsive (input device detects being plugged in) but nothing comes out of the unit. Even resetting the microprocessor or running in service debug offers no clues. Its otherwise operating normally, powers on, front screen works, web interface works, just no output on any interface including pre-outs.
Its fast becoming a more advanced problem than I am probably capable of fixing by having to diagnose microcircuitry but I am hoping that someone may have experienced something similar and I’m missing something simple or may have access to a higher res service manual?
any suggestions welcome

Scrap it, the parts and time will be more than a new one.
Marantz is mostly trading Chinese stuff, and there models change like cell phones, finding a display for a 3 tear old cell phone is difficult and too expensive.,,Same for this
