I think I might have done something wrong to my PS3. This all happen a few days after I downloaded hen on my PS4. I was trying to play a disk game and it got stuck on a blank screen. So I unplugged the ps3 and now it won't come back on. Anytime I try to go to safe mode it only shows green dots on the TV. I have tried to use different HDMI cords but the same thing kept happening. Can anyone tell me what I might have done wrong and how to fix it?
