wurD93, when you stated that you reinsert the cable, did you do that at the WODE stand?
Zephyr, I am able to play a game using FLAT mode. Would that mean the cable in the Wii is installed correctly? For the cable at the Wode stand, I had the blue facing toward the side that have USB port the sam way I saw it when I first opened it up.
If you can see the LCD text and select flat mode then the cable is in the right way. I do not remember which way round the cables go. There is a tutorial on here with pictures somewhere.
It seems you either need to open the Wii and reinstall everything again - which many other did even though the stated it was installed correctly - and this fixed the issue most of the time.
After that if the issue still remains it is likely you _might_ have a faulty slave board. I would contact your reseller and see if you can get an exchange / replacement WODE
