I've done all of the advice. We bought this for Xmas for my son, and it doesn't work.
Often it freezes on the start screen, no noise, it just flashes 'press A to start' ad infinitum. If it doesn't freeze then, it will do within five minutes.
We have 1937 blocks of space. no internet. The cords are all straight with the portal away fromthe Wii.
My son has been crying on and off for 24 hrs. as am I now as this was his only Xmas gift from us and he is so distressed.
We're very sorry to hear your son has been distressed over the matter. I've moved your post into a new discussion since the previous one was a bit older.
Can you please try clearing the block(s) related to Skylanders Swap Force and restart the console once more? Also, indicate if you are experiencing any other issues with the game. The more details you can provide will help greatly.
