Black screen even after changing bluetooth chip
I have a Wii that until recently was working fine. Had BootMii installed, booting from SD card. One day it stopped working - it would show the BootMii screen, but when it was supposed to load the home screen, I got just a black screen. Without the SD card, it would go straight to the black screen. Never got to the “health warning” screen.
I can go from BootMii to the Homebrew Channel, but I can’t load anything from it (black screen again).
I tried unplugging all the adapters, leaving everything unplugged for a few minutes, and trying again; this didn’t change anything.
I tried recovering the NAND from a backup in the SD card; this didn’t change anything.
I ordered a new bluetooth module, disassembled the Wii, and replaced the module; this didn’t change anything.
At this point I’m not sure what else to try. Any suggestions?
