With the sd card in, the health screen doesn't show. Instead, blinking blue on disc drive and blinking green and black on the power led. Without the sd card, the health screen appears.

Service mode? you must mean the "Maintenance Mode", which is accessed by pressing A on the H&S screen while holding down the + and - buttons on a Wii Remote, not by pressing A and B at the same time on the H&S screen.You can try one thing:
- remove the Modmii folder (that one that XFlak recommended)
- put the SD Card in your Wii
- power on the Wii
- on the HEALTH SCREEN PRESS and HOLD "A" + "B" Button together and press A to continue
-
Can you reach the Service Mode from the Wii ?
Good luck.

OK, can you get into the Wii Settings menu? if so, look at the upper right corner of the screen, and tell me what number it says it is.It works! Thanks! Is there any way to boot it up without maintenance mode? If not, it's fine.

if you don't have a Wifi router, (or a modem with one built in) you can use the LAN ADAPTER!!!!I want to try the smash stack first because I don't have internet on my Wii. I realize it's easy, but I want to hold off for now. Thanks though!
Edit: If I homebrew, can I get the Wii to work like normal?

If the behaviour is at all different when there's an SD card with bootmii on it, that's a good sign. I could be totally wrong about this, but I wonder if your tv isn't able to display whatever the video mode is set to when bootmii launches. This can be customized and changed in bootmii's config file.And yes, I did what XFlak recommended. Except, it doesn't boot, it blinks instead of just a health screen then a black screen.


The transfer tool will still work.I have a Wii U, and I was wondering if I could transfer the Wii's data to the Wii U. Normally I could use that transfer tool, but, that doesn't work because the shop channel has discontinued. And my Wii is, of course, bricked.

Well, you'd need to Un-Brick it first. (I'd recommend replacing the disc drive too)Good, can I transfer data from the bricked Wii to another Wii?

You need to A: find a savemii dongleHow do I unbrick it without losing saves? Can I do a NAND format?
