Color Banding and DAC issues.

[finakechi]

I'm trying to troubleshoot my AVE-HDMI install and can't pin down what's causing these issues.

I have some pretty nasty color banding on the home screen of my Wii.

Certain test images from 240p have serious issues, others do not seem too (or at least ones noticable to me).

And lastly none of my DACs will recognize the sign from

it.

Looks like you have open/shorted/misconnected VData lines. Grab the updater from the latest release, start it, use About->Update to go to the flasher mode, but use the Diagnostic mode by hitting right on the IR remote or the D-pad of a Gamecube controller in port 1, it will probably report which lines are affected.

Awesome, I'll give this a shot when I get home and report back.

I apologize if this is very basic stuff I'm asking you.

But how exactly do I get into diagnostic mode?

I downloaded the updater, put it on my SD card.

I attempted to launch it from the Homebrew launcher, and immediately lose my HDMI connection.

Pressing right on my GameCube controller does nothing.

Using the update firmware option in the OSD does the same thing, HDMI connection loss.

I'm not really sure where/when to press Right on my GameCube controller

Huh, interesting - the flasher mode uses a simplified video setup that should in theory be very compatible - but it might get confused because your console clearly has some issues with the video signals. If it were my system, I would open it up and use a multimeter to check each signal from the console to the FPGA for continuity and shorts.

It looks like this "AVE-HDMI" thing uses a flat flex cable soldered onto some signal-carrying vias - that sounds like a recipe for just such a disaster to me, but maybe the vendor has some additional troubleshooting guidelines for such cases.

I might have accidentally found the affected traces since I have the exact color banding problem on my ave hdmi board. Going to be totally honest, I messed up my install back when I was very bad at soldering and internally broke two traces from the pad to the fpga, so I had to run magnet wire from the fpga to get continuity. I went from having no signal to having signal but with significant color banding. The affected trace I believe is D2 and 54M.

I was able to run the diagnostics tool and attached below amongst the other pictures are my results:
