My Mac shuts down when I downloading the software update *flickers too

A few weeks ago my Mac started flickering uncontrollably. I thought it needed a software update since I haven't updated the software for a while. While the update is downloading, at the same time my screen flickers. After the update is finished the Mac shuts down. I switched on the Mac to find the update restarted the download and my screen still flickers. Can I fix this

Can you take a screenshot of the flickering?

If the picture comes up clear then it might be a flex cable issue.

I would also suggest trying an SMC or PRAM

DISCLAIMER: The following sequences are maintenance/developer controls and have a very low risk of causing data loss or possible corruption. The chances are very low, less than 3% but I just thought I'd give you or anyone reading this a warning before using these methods. Do so at your own risk.

SMC: Control, option, left shift and the power button. Make sure you're charger is plugged in and there are no USB drives or anything else plugged in. If performed successfully the charger light will change from orange to green back to orange.

PRAM: switch off the device. Press the power button then immediately press and hold P, R, left command, option. Hold these down for about a minute, during that time the screen may flash white and the start up tone will play. Let that happen 3 times then let go and let it boot up normally.

I hope this helps.
