Mental, did you happen to notice any smells ( such as fired components) in the power supply section. Located right around the same area the cord goes into the PS2?

Did you noticed anything else plugged into the same outlet or breaker that had been reset or is no longer functional? ie... an alarm clock that has been reset, or vcr/dvd player that had to be reprogrammed?

If any of things oocured, it would seem to me that your area experienced a power surge in the middle of the night and or the electric company switched from one generator to the next. This sometimes introduces power surges or spikes on your 120v/60hz power lines. It's a very common condition, one known to make electronic repair shops tons of money. The fuse in the PS2 power section is a very sensitive type (non slow blow), inorder to protect your unit from these voltage/fire hazards. If you are out of the warranty period, then I suggest you take a look at this fuse. You can get the shcematics for your playstation online. Same place where you would get the information on how to chip the PS2. It's not very difficult at all, and its easy to tell a bad fuse. I am almost certain this is your problem based on the description of the anomoly. Let me know if you need any more technical assistance.

Hit me up on aim when I'm on.
