As demand for SixtyFour keyboards is on the rise again, I’ve got a real all-rounder here when it comes to keyboards. A mod that should really win everyone over. Perhaps even a genuine alternative to 8bitdo.
The SixtyFour keyboard mod on an Akko 5108B Plus keyboard with ISO-UK/DE/US/FR/IT/ES etc. layout. Gaming keyboard with hot-swap RGB lighting. All possible connectivity options, including USB Type-C, 2.4 GHz and, of course, Bluetooth 5.0 wireless.

I'm not sure who can help me or what I can do to fix this, but I had this console modded years ago and took it out to play the other month and I can't get any video output. I can hear the title music but no video on my Retrotink 5x using a Insurrection Industries Luma cable and also tried a CSYNC (I think, from the same company but the cable isn't labeled and I bought it awhile back. I thought maybe I was using the wrong cable). The company who installed this for me is still operating, but completely ghosting me for months. I had them mod like 10 consoles from me and they are working fine years later except this one.

See anything wrong?

First installation of a Mega Switch HD with audio ADC and Board-C for Master System mode was a success. If anyone has questions, feel free to ask :)

After some helpful suggestions, I went back and was much more careful with soldering, but I can’t see why I’m not getting a signal at this point. Using a bitfunx adapter in the AV port works fine, it’s set to Component in the settings, I’m taking 5V from the USB port, and I get a tone when I check each point for continuity. Is there something else I could be missing? I feel like it's something simple or maybe I just got a bad HDMI unit?

This is a PS2 Slim 70001. Any help is appreciated!
