I've been having some problems with these lately. This is the third one. Tried heating it with heat gun, and tryed reballing ... Sympthoms remained..
Thanks in advance.

I'm a bit confused, what problem, what did you try reballing, symptoms being blank display? did you verify that your inverter is working properly and that connections are still in working condition?

does the pc power up at all? have you tried an external screen?

Inverter, connections are ok. Pc does power on, but it doesnt light up the external or internal displays.

then your problem is likely either motherboard or videocard
