This has just started happening, but it only happens when I am playing Rock Band 3. It happens at random points, too. Different songs, different modes, etc.
I don't suppose anyone has seen this before? Or, is there a diagnostic check I can do on my PS3 to see if there is anything wrong with it?
Its a known issue with RB3 on the PS3 thats been there since the game launched, there is no fix that I have ever found to fix it. It really sucks when your in the middle of those long set lists.
