Yup. 5 years after I bought it, my PS2 would boot directly to the OS instead of the game. Took it for repair and when I brought it back, it happened again, so repair again and it happened again :\
So I decided to open it and look around, after it opened, I decided to see how the disk spins inside and stuff, so I plugged in the power and lo and behold! It was working! (without the cover) So it works now and I never put the cover back on ever again.
