Thanks for reply. Power supply is fine. If it was power supply, it would not turn on again after some time. I wonder if it is PCB or Fan but again I can't understand why it turns on after a few hours.

I have 3 years old Alpha CB28C which for some reason locksout. All lights goes off like there is no power supply. After some time, it starts working OK. It happens randomly. Whenever it goes off, it wont come on again for about an hour or so. What can be wrong with it ?
