MacBook Pro 2017 Touch Bar doesn't start any more when I open the lid

Reset the SMC and NVRAM:

Sometimes changes take place while your Mac is being used, making it operate not as intended (In this case, the screen and touchpad). Use these Links:

• How to reset the System Management Controller (SMC) on your Mac - Apple Support
• Reset NVRAM or PRAM on your Mac - Apple Support

As a Last Take this in for Service:

It's just after the beginning of 2020, so, if you have AppleCare Products - Mac - Apple, then it would still be an option. With that, then there is a high chance that service may be of no charge, should it be nothing on your part: Accidental or Intentional Damage

If it will not power on when you lift the lid, go here: If your Mac doesn't turn on or start up

”I did NVRAM and SMC reset but it didn't help. With NVRAM reset (I have T1 chip and no starting sounds) during key pressing light grey screen appeared twice as a flash, so I suppose reset was ok.”

———-

The NVRAM Reset May Not have been Ok:

Does your Mac power on, once the lid is lifted?

And are you able to login as a user?

If your screen flashes, then the reset was not OK. There will be no starting sounds.

Call Apple:

This is not of normal behavior for a Mac. My last though is that the cable is loose between the Logic Board and the screen.

If you have an iPhone, request a prompt for screenshare. Enable the camera, and open the camera App. Show them what is occurring. That way, they can see this up front from your point of view.
