My first post - but unfortunately I'm going to be adding to the list of woes you guys have been experiencing.
My Wii worked fine (for about an hour), until I decided to Synch the additional wiimote I bought. This failed to activate, and the same process also managed to kill the factory synched one that'd been working fine.
I've tried to re-synch the one that came with the machine many times, but the four blue lights just keep on flashing for ever (at least 5mins I tried once), until I give up. I've tried unplugging the system as suggested, but this hasn't fixed it either.
I've been a lifelong Nintendo fanboy, and I'm chuffed at the success Nintendo are having with this new hardware, and that they are leading with innovation (not sparring with Sony and Msoft over polys and speed), but I think they've let us all down by rushing it out too early - before they'd tested it fully enough.
I'm gutted - it looks like I'm unlikely to get a replacement before Christmas, and my kids haven't even had a chance to see it working yet - they're due from school in a couple of hours.
If anyone's got any other ideas, I'm prepared to give them a go. Cheers!
