17" early 2011 - dark screen+ keyboard and trackpad not working

[temen]

while external monitor with external mouse works fine! (yes, I tried resseting smc/pram)
For some time now macbook was sometime going "dark" (just the screen, I saw from other machines that it was responsible for pings, connecting to ssh and so on). Now monitor won't even light up, keyboard and trackpad doesn't work.
I doubt all 3 parts are broken, maybe some sensor is telling macbook that lid is closed?
when lid is closed keyboard and trackpad are disabled?

Well there's an easy check to see if that could be the case. Plug in an external monitor and see if it works

As I said in the first line -> "while external monitor with external mouse works fine!"

Sorry, I missed that entirely when i read it somehow

If it were just the screen I'd say the backlight was blown, but since keyboard and trackpad are not functional too - no clue

Have you checked for battery swelling?
