The problem might just be torn display ribbons that were somehow damaged by the constant flipping motion, as I've seen a lot of 3DS and laptop screens fail because of a bad display ribbon. Also, this particular model seems to have a "flexgate" problem. The ribbons on this particular MacBook Pro is more fragile than on other models, which leads to a flickering backlight even if you're flipping it carefully. That's actually a more plausible cause to your problem, since your situation matches the problem description of others perfectly. You might be able to find somebody who's skilled enough to fix the ribbon itself. But, as Dan mentioned it could also be the battery or the GPU. The problem could be either be an unstable voltage output from the battery or a GPU that's somehow desoldered or toasted itself. Or both. Anyway, whatever the case is, you DEFINITELY needs a new battery. It's holding less charge than an Apple Magic Mouse. [br]

Here's the guide to remove the screen. You will be able to check the ribbons easier with the screen removed. [br]

I assumed that something is wrong with the display ribbons before, but after what Dan told me I think that's unlikely. As Dan mentioned it's probably a GPU problem. The problem could also be either be an unstable voltage output from the battery. I will stick with the opinion that you need a new battery though. It's holding less charge than an Apple Magic Mouse.
