MacBook Pro 17 inch screen goes blank 2 minutes after booting up

MacBook Pro 17 inch screen goes blank 2 minutes after booting up.

I replaced the battery and the charger, still no results. I replaced the logic board, still no results. Tested booting up with both Memory sticks and then individually, still no results. Please advise.

It might be the inverter board..the age of the Mac points to that and with the logic board already changed I believe there's not much else to be tried. Here you have a guide to the inverter replacement:

To see if this is correct, when it goes out hold a flashlight at an angle to the screen and see if you can discern the desktop.
