Backlight flicker

Hello, I had my MacBook sent in because the screen is flickering, it does this every morning and during the day after the mac comes out of sleep.

When mine came back from repair, a battery part was replaced (and I think I got a new battery too..) but the very next morning I'm having the same problem. About 5-10 minutes of flicker before the display is solid, like it's warming up.

I realize I'll probably get a lot of responses about others having this problem, but what I'm looking for is someone who had this problem and can tell me what their solution was.

Thanks in advance!
