Just got back home so I have access to my docking station + external monitor.
Tried to run PSA diagnostics - using only laptop without external monitor gave me code: 3-2-1 and screen was black without backlight during the test. Whatever I try I always get black screen on my laptop... Only Power+d shows that screen is working.
PSA test was successful when run on my external monitor.

The issue required a Dell Tech. vistit - problem was with LCD cable(probably partially damaged so it partially worked ).
Issue is now solved.
