Hi,
Try connecting an external monitor and check whether its' display is also flickering.
''If if doesn't,'' then it might not be a problem with the GPU but possibly could be either:
1. faulty video cable between motherboard and screen (press around the screen 'hinges' area (this is where the cable passes through from the body to the lid) and see if you can make it better or worse.
2. faulty video cable connection either on the motherboard or on the screen.
-3. faulty backlight power supply feed. (the backlight power to the screen is controlled by the lid switch. This switch, usually magnetically operated, either directly disconnects / connects the power to the backlighting when the lid is closed or opened or sends a signal to the relevant section on the motherboard to software turn on / turn off the power to the backlighting.
+3. faulty backlight power supply feed or lid sensor when the lid is closed or opened a signal is sent to the relevant section on the motherboard which sends a signal to the screen to software turn on / turn off the backlighting.
4. faulty LCD screen
''If it does,'' then there is a problem with the GPU on the motherboard.
Here is a link to a video showing the [https://www.youtube.com/watch?v=ylp_x3VKx2I|dis-assembly] of your laptop, which may be of some help.
