i recently purchased a used ps3 from a lady that claimed it worked but it doesnt. she said her husband cleared of their info and it was working but when i got it home and tried it out the next moring, because life kept me busy the remainder of that day and i didnt think i was being dupted, it wouldnt work. i have an older ps3 i bought off ebay that came from another state and survived shipping without issues and works perfectly so i know it wasnt damaged from the trunk of my car to my childs dresser. she didnt include the tv cord because she claims when purchased new this cord isnt included. im unsure of this because like i stated before i got a used one and everything was included. i have an older ps3 so i used the cords from that one to plug up the newly purchased unworking one and the light came on but there was nothing on the screen and you could not hear anything. i know it isnt my plugs because it works on my old ps3 no problems. just fyi the old working one does not have the sd slots but the new/used nonworking one does, if that makes a difference in the needed cords. i am unsure of what is the problem since she claims it worked. i know it doesnt and id prefer it work then my money back because it was a early bday present for my son. PLEASE IF YOU HAVE ANY SUGGESTIONS OR MAY KNOW WHAT IS GOING ON, HELP!
