I’ve been using a American PS3 in japan for a month now. Now the ps3 just shuts off after a couple minutes. It’s not a normal shut off. It shuts off with like a sound. Like pewwwwww. Then I have to press the power button twice for it to come back on, but the it shuts of immediately with the same sound. It’s been working just fine until now. someone help?!!?!!?!
