How To Fix PS2 Red Light Problem

I use my PS2 for about 5 minutes, it then all of a sudden shuts down and the red light flashes. The light won't stay green continuously?

Your PS2 console is overheating that is why the red light is blinking all the time. The console has a built in protection circuit that shuts everything down when the operating temperature is beyond normal. This is to protect the hardware such as the graphics chip and processor unit from getting damaged.
