About 3 weeks ago I bought the PS3 Slim at Target and about a few days after buying it, the PS3 was making popping/cracking noises every 10 minutes when its powered on and when it was powered off, the same noises started every 15 minutes for a total of 1 hour. On my Target receipt it states that returns are only valid for unopened items. Last week I sent my PS3 for service and I would like to know if I would get my system back or that Sony will ship me a refurbished PS3?
