Onkyo TX NR906: No HDMI Video Output - Troubleshooting and Firmware Update Tips

Hello,

I am a retired Dutch electronic technician, now living in Spain.

After using Google I found this site.
I have a problem with an Onkyo TX NR906, it does not give any picture out on the HDMI ports.

When I check the firmware versions I see information on Main, DSP1, DSP2, DSP3, HDMI, NET, NET usr, NET rfs, NET krn , NET ipl, but only a blank line on VIDEO:.

It was a gift to me, so I started to replace all capacitors on the HDMI board, this did not change anything.
When it came to me, it had Main FW 1.00, and I was able to upgrade using the serial port to 1.05 and a Windows-98 PC, but this did not change anything with respect to the HDMI output.

I do not see any setup screen, nor any video input.

Is there any information about what could cause this available?

Thank you for any help available,

Leo

I have the one for Pioneer 1051 it's the same, full fix,,

If this helps, I had a similar topic in the TX-NR515. It is completely unknown how the contents of the memory of the video controller itself were cleared. All other software was ok. For me it was Q8040 W25Q128BVFIG. When I desoldered it and checked it was very clean. I found a batch for it and uploaded it. After this operation, I have already done the traditional upgrade and everything worked.
