My 2016 MacBook Pro 13 inch screen shuts off after opening the lid. If I only raise it about 45 degrees it stays on. Once it reaches 50-90 degrees depending on how slowly I raise it - the screen goes black.
But connecting via hdmi to a separate screen everything still works but display on laptop is black. Obviously a switch in the hinge is bad? Can I fix this myself?

It looks like it is a well-known problem for the model you have. Luckily it looks like Apple are offering free repairs for just this problem due to it being a design flaw. If I have understood everything right, you should be able to contact Apple to get it repaired for free. :D Hope this is the case and good luck! :D
