Well thats a load of propaganda. But feel free to preach your views on the matter. You didn't even ask why I put 2 sets of AV cables in there, but assumed it was because there was a defect to help your creditability of the story along. You are a piece of work. I understand you are upset because upon arrival you are having issues... but the system was tested before I packed it all up because I played guitar hero one last hooray before I sent it.
If you want to put blame and yell and cry... I would say that you need to look to UPS and how the product might have been handled. If it was dropped or something or feel off a shelf or someone tried to balance of few boxes and this got banged around, thats not my fault. Those are risks you take when buying used items, as to items you purchase in store with a warranty to cover that sorta stuff when you get home.

Have a good day.
