"Why doesn't my PS3 have a signal on my TV?"に関する回答Tried every solution posted above using multiple input cables and controllers on a TV where three other systems were already working perfectly. Still no picture or sound from this old PS3… it turns on and the fan blows to give you the impression that it’s doing something, but that’s all it can do. Controller doesn’t even light up when plugged into it. I’m thinking someone sold me a dud.
