My PS3 won't turn on D-:

It's not the Yellow Light (I think), but the other day all I got was sound but no picture and now I turn it on and don't get anything. :-(

It's probably your cables, also try holding the power button for a few seconds to reset it

Yeah for one reason or another it sounds to me like you need to reset your ps3 as a few others have mentioned on here. Once you reset it by holding the power on for about 5-7 seconds (till u hear the double beep or w.e) it should recognize the hdmi set up and than just select that.

try a different wire and a different tv, if those dont work then you might have a messed up hdmi port on your ps3 like i did a few months back
