No HDMI signal at all

[ceesvanegmond]

Hi there,

In 2020 I bought the FPGA board from KNJN (Item#6117 (Pluto-IIx XC3S200 HDMI) (pre-programmed with GCVideo 3.1 for Gamecube)) . It is preinstalled with GCvideo for Gamecube. It's a revision F board so the DCC fix should not be needed.

Last week I finally had time to install it for the first time. I think everything went very well; except that I cannot seem to get an HDMI signal from it. I tried multiple TV's and Monitor's so I think it's an wiring issue. I already tried to see if there any loose wirigns or miswirings or potential bridges but so far I cannot seem to find it. When trying out the Analog signal; that also doesn't work anymore; well partial. It does gray/white but no colour.

The two leds on the board are on. One is green the whole time and the other one is blinking green; which should be good.

Could it be possible that these two problems relates to each other?
I don't know where to start right now :-)

EDIT: I think I already see the problem. In the beginning I was struggling alot with the removal of the Digital Port and I broke 3 traces, namly 9, 13 and BLCK. Are there via's I can solder direcly to?

I had the same problem but I couldn't find any bad traces. Did you try the original A/V port? I'm pretty sure with mine I spend soo much time messing around with the chip itself, I didn't pay attention to not having thermal pads on the heatsinks and it got toasted that way. I've since installed a new motherboard I got for cheap but haven't attempted to mess with this again. Although, I'm planning on trying on a DOL-101. There are alternate connections directly to the chip which are present on both revisions of the board.

Take note that connection CLK SEL is "color select" and DATA is actually ADATA.
