Based on personal experience...

About a Flickering Mac Screen:

A. Your Screen is Failing:

I have come across this on my 2017 Mac. The connector between the LogicBoardand the screen when loose, and I had to send it in for service 11 times. Being during COVID, I had to send this in. Today, the option to take this in for service is an option. So take this in for service, ASAP.

B. To Get this Mac Serviced...

Contact Apple, and setup a Genius Bar Appointment or see an AASP (Apple Authorized Service Provider) in your local area.

A. Contact Apple:

• Contact Us - Choose Locations
• Proceed from there as Necessary
• NOTE: Due to the Coronavirus Pandemic, calls are taking a bit linger to get through. And, that makes sense, because many are at home working out-of-the-house or are taking classes over-the-web, this they have more time on their hands to contact Apple Support. So, it might take a bit to get through to Apple Support. But, just stay on the line, and someone will be with you.

Or...

B. Contact an AASP: 

1. Go Here: Find Locations - Apple Authorized Reseller
2. Click: Service & Support
3. Enter: your location information
4. See: if there is an AASP nearby
5. Contact: an AASP that shows up, and find out more about the services that they offer to fix the Mac

Replacing a Screen Yourself:

No. It is a tough practice, and you must have prior experience on doing so. Do not reply on YouTube videos, as they can be misleading. I insist that you take it in for service, if you have never performed this yourself.

Getting the Cost of a Screen Replacement:

You need to take it in for evaluation. From there, you will be provided a price. It may be half the price of a new 128GB Mac.

That's YOUR call.
