Vertical colored lines on the display - MacBook Pro 2016

I see lot of colored vertical lines on my MacBook Pro 2016. I started seeing them randomly almost a month ago and they are persistent. The lines vanish when I am on a webpage which is has white color or have a background which is white. I am thinking it is some problem with the connections to the display. But can't understand magic behind white color rendering. Any help is appreciated.

I looked for similar posts, but seems like every case I found is slightly different than mine. Please help!

MacBook Pro 13″, macOS 11.0

I am sure that the options that I am about to present to you, to address your issue, have already been tried by you. These options due a great job addressing software related issues. If none of the options work for you then you can almost bet on this being a hardware issue. It may be related to the display or display cable or the logic board.

Reset SMC by following the directions applicable to your MacBook here ➔ How to Reset SMC. If that does not solve things then-
Reset NVRAM/PRAM by following the directions applicable to your MacBook here ➔ How to Reset NVRAM/PRAM. If that does not solve things then-
Enter ➔ Safe Mode and see if the screen issue still exists in Safe mode. Log out of Safe Mode and then reboot computer. If that does not solve things then-
Finally if none of the above works then you can enter ➔ macOS Recovery Mode and reinstall the macOS and see if that solves it.

Well then Vasudeva, we may have a hardware issue at our hands. The only way, now, to find out and confirm is by having your MacBook Pro examined at the Apple Store or at an Authorized Service Center. If the stores are not open then I recommend that you Please contact ➔ Apple Support

Well, thanks for the recommendation. I did go to the Apple store. Perhaps only option they had was to replace the entire screen unit for $478+tax. But the screen is not physically damaged as far as I can see, I am suspecting some loose connection with cable or cable might have been worn out. I want to see if anyone here has some suggestions/ hacks for me to solve this problem without having to spend major $$. Already this laptop is 4 years old, instead of spending on this, I can probably spend on new M1 MacBooks. /shrug
