Whenever I try to boot up my trimmed Wii with a PMS, I get a black screen. To power my board, I am using a PMS bought from the BitBuilt store which outputs the correct voltages on every voltage line. When I power on the PMS, I get 3.2v on pin 4 on U10. The bottom three pins of U10 are connected to gnd and pin 5 is connected to the 3v3 line. The GPU pin and pin 4 have continuity. It does not matter wether or not I disconnect 3v3 from the MX chip, the WiFi module or the BT module, I get the same black screen. I have tried to boot with the minimum required components connected (eg. only U10 and WiFi). Yesterday I determined I broke my U10 because there was no 3.3v on the pin 4 after poweron, so I replaced it with a U9 chip from a 6-layer donor. I did short that GPU pin that goes to pin 4 on the U9 to gnd once, could that have messed thing up? None of the voltage lines are shorted to gnd or have abnormal resistance to gnd. I do not have the data lines from the USB connected to the board. I have tried connecting several spots on the board to the composite input of my TV, I just get a black screen until I power the PMS board off. When I connect reset to gnd, the image stays black and the Wii does not boot to anything. My trim is slightly larger than the trimming guide suggests, I cut about 2mm outside of the red line. I did not install No-WiFi ioses which is why I wired up the WiFi chip. I measured continuity between every data line on the WiFi module and all of the lines are connected to the board properly. The video encoder and CPU/GPU heat up when the Wii outputs a black screen. The board worked fine before trimming. Anything I've missed? I have no idea what the problem is... (btw there is a wire soldered to the 1v8 spot on the Wii, but it is not connected to anything) Perhaps the wires from the WiFi module are too long?
