Monitor turning on but no picture

My monitor has this problem where i am able to turn it on, but no picture shows up on screen. The weird thing is, after 3 days to about 2 weeks of not using it (the monitor), it suddenly works again, and then around 3 months later the problem appears again. I have tried using different power cables and different power outlets, but still no picture.

Monitor: BenQ XL2411
