Wait a minute - this PS3 he sold you doesn't play PS1 games? That's impossible (unless it's broken) because ALL PS3s play PS1 games. It's the PS2 games that are no longer playable unless you have the original 60GB, 20GB, or the 80GB with 4 USB ports and memory reader (Motorstorm or Metal Gear 4 bundle). But even the newest PS3s play PS1 games, so that shouldn't be a problem.
Edit - I know you said it wasn't playing PS3 games either, so surely it is just broken - but I wanted to point this out about PS1 games, because you posted you called Sony and they said the model you have doesn't even play PS1 games - that has to be incorrect.
Actually,If you look on the Official Sony Website,there is a section that shows you if the model that you have is compatible or not,and according to the site the model number CECHK01 is totally non backwards compatible.
Oddly enough,if you search a little further on that page,it says that it's compatible with only select titles.But to even further contradict themselves,if you click on the button that shows you if your PS1 game is compatible,it only gives you the option to pick between two PS3 models,and the CECHK01 is not one of those choices.
I guess I'll take the operators word for it,but regardless of the compatibility,he sold me a bunk machine.
UPDATE:
I just came from the police department of the town that he live in,and they said that I had to file with the court clerk and that the police weren't allowed to get involved in a civil issue.But he sounded very optimistic for me,considering I had a boat load of info on this guy.So I guess I'm going to court tomorrow.
