Not sure if this belongs here, but w/e
Apparently this is a recurring issue, but all I could find in Google were idiotic answers like "uhh maybe its out of batteries" or "are u sure its on?", but I know you people are smarter than that.
BTW, this is the guitar model that doesn't need a Wiimote. The guitar's lights don't stop blinking, even after I follow the steps to sync it with the USB receiver. Actually, all they do is blink. After blinking for some minutes they just turn off. Once I managed to connect it but it disconnected within a minute. I've opened the guitar and all connections are ok; I cleared all the Wiimotes connections and the batteries are new. It worked just fine when I last used it two years ago.
