Hi for a while I have been interested in building a GBS-C,

So I finally did. However, after soldering everything together I got a blank screen. So I tried to check if it had something to do with the settings. I tried changing them to check if that would change anything, this did not help. So I reset everything in the menu. Tried to use a vga cable instead of my vga to hdmi converter. In this case I get a message on my tv screen saying that the input is not supported. So I assume there must be some signal leaving the GBS. I have read that some people have had issues with the purple clock generators So I resoldered the points I had attached to C41 to C48. But this did not change anything. I have double checked my soldering and I think everything should be alright, so I have no clue at the moment why the GBS-C is not displaying anything.

Does anyone have a clue about what could be wrong?

I got a blank gray/black screen on my first time connecting it to my ps2 and tv. I got the exact same tutorial as you (voultar method) For me what fix it was to press once the physical RST (reset) button on the ESP module. Then I got image and all operative.
