Usually a bad BT module will not power on the wii with the wiimote. It is possible, you can test the BT module by loading games from the HBC. Use a gc controller and see if you can load any games. Games should not load with a bad BT module. Another test for the BT module is savemiifrii, savemiifrii should work with a bad BT module. If savemiifrii does not work it should not be your BT module.
Other possible causes could be a bad wifi module or dead DVD drive, both would give a black screen with savemiifrii. You can test the DVD drive by unplugging it. You can test the wifi module by replacing it with a known working one

 

You can sync the wiimote from the strap screen of a game if the wiimote is not sync with the wii. If the BT is bad the game should black screen and not give the strap screen, but Savemiifrii should work, and a synced wiimote typically will not power on the wii.

 

If the BT module is working, try to load Multi mod manager from the HBC or via cboot2, then reinstall the system ios. See if reinstalling the system ios helps, if not try to also reinstall the system menu. Posting a syscheck log could be helpful if that does not fix the issue.

 

You could have bent one of the pins when plugging it back in. Speaking from experience

 

All the Games through USB loads fine and playable. Although I did check the pins but would have to check again if any of the pins got bent while plugging it back in.. any other suggestions?

 

checked all the pins and looks fine nothing bent... oh well... I can live without dvd since usb loading works.. just that it was working just fine before I changed the bt module...
