I am able to get online fine and connect to games as normal, but after about 10-15mins of playing the game my TV goes black. The console is still on, but if I press the center guide button on the controller, I cannot even get back to dashboard and exit the game, nothing shows. Any suggestions? I had the Red Ring of Death fixed for a second time about 1 month ago and has been working fine until today. Are the problems connected? Thanks for any help.
