If you have already updated the software then this sounds like you need to take it to the service center. Does it always do the flickering when you first power it on? Then it should do it for the staff at the service center. That would be my recommendation.
The alternative would be to restore the factory image but you would lose all of your settings and it might not fix the problem. This really does sound like some sort of hardware issue.
