I am having Marantz model NR-1402 and faced with problem of no output from HDMI. I was indicated price of Rs.16000/- + repairing cost. But was not informed about replacement of IC is possible.
Now I am using the AVR by connecting Vedio signal from my WDTV directly to TV and audio optical out from WDTV to AVR. This is the simplest solution I have found for this problem with excellent results. No repair cost nothing !
