Most PS3 users experience the yellow flashing lights at some point and they don't know how to fix the problem. They turn on their console and the red light turns yellow, only to flip back to red and begin flashing quickly. Instead of booting up the system so games can be played, the system seems stuck on these flashing lights. The bad news is the PS3 yellow flashing light is a common problem, but the good news is the problem is not very difficult to analyze and fix.
The first cause of PS3 yellow flashing light is with your hard drive. Sometimes the connection between the console the hard drive can mess up and in other cases a hard drive can go back and might need replaced.
