About to buy a PS3, but it doesen’t read disc!!! Anyone know a FIX???

Hey, I already own a PS3 but a guy is willing me to sell a PS3 for $50 Bucks.

 

But here is the Catch: The PS3 Doesen’t read disc.

 

So what is the best option to do on how to *possibly* fix it from NOT reading disc? 

 

Should I…

 

• 1.) Restart System: Restarts the PLAYSTATION®3 System.
• 2.) Restore Default Settings: Reset all system settings back to default.
• 3.) Restore File System: Checks for corrupt/missing system files.
• 4.) Rebuild Database: Rebuilds the OS for the PLAYSTATION®3.
• 4.) Restore PS3 System: Fresh restore; Deletes everything and starts from Scratch.
• 5.) System Update: Update the PLAYSTATION®3 System

 

 

Thanks, Uhh I guess Kudo’s to the best answer :D
