Freezing up at Black Health Screen
When I boot on my Wii, it loads as far as the black "Press A to continue" screen warning about seizures and epilepsy or what have you, then... stops. In fact, the option to press A never shows up and I am unable to connect the Wiimotes.
This particular Wii is not modded though I have soft modded two previous Wiis with no problem.
The only suggestion I seem to have found is to boot up a disc of New Super Mario Bros Wii, as that contains the 4.2 update and this error sometimes occurs if an update is corrupted. However, I don't have a hard copy of the game handy.
EDIT: Tried booting into NSMB after leaving it unplugged for an hour but no dice. Also, the Wiimotes now connect for some reason, but it seems to be unrelated to the game.
The resource files of the system menu (stored in NAND flash) are corrupted; there is no way for you to repair it yourself. If the system is still under warranty, you are best off sending it back to Nintendo. Otherwise, you can replace the main board.
