I've learned a lot here and decided to try making a portable Wii. From installing RVLoader to testing resistors everywhere, everything went smoothly until I encountered an issue with my 3.5-inch 640*480 screen.
I wired it up, but couldn't get the screen to light up in VGA mode. I've tested the soldering repeatedly with a multimeter, initially thinking it might be due to having only one ground (GND) wire. However, even after adding a second GND wire, the screen still wouldn't light up.
So, I soldered the AV output, and it worked (though the picture quality is a bit poor). Can anyone help me figure out what the problem might be?
Here are the diagrams after I disconnected the AV wires and changed the GND connection point, but it's still showing a blue screen. I've tested all the solder points with a multimeter, and they are all connected. This is frustrating, I haven't even started trimming the PCB yet.
