The problem may be caused by a failing inverter sub-system on the logic board. Checking if the inverter socket on the logic board has voltage would tell you if the logic board is faulty or not. Try to find a tech that could check this for you.

Have you tried hooking up an external monitor? Did that work?
Lemerise please correct me if I am wrong, but if an external monitor worked would that mean the sub system on the board is fine?

Yes you're right but in the current situation the OP has a screen lightning issue and this is not related to the graphic chip but could be caused by a another bad component on the logic board if no power is reaching the logic board output inverter socket.
