How can I troubleshoot my MacBook Pro that no longer boots after a thunderstorm?

I have a MacBook Pro. Few days ago it shut down automatically while there was thunder and lightning. Now it doesn’t start. There is no image on the screen, no chime, no keyboard back light.

I checked the hard disk, RAM, battery and the charger, which are fine. Connected to an external screen, but there is no video. Removed the RAM and I hear the beep sound, so I think the mother board is fine. Couldn’t check the processor. The ventilator is running and I can feel the heat of the processor after some time.

Don’t know what else to do. Any help or suggestions will be highly appreciated. Thanks a ton

    Shelbi, have you followed ha14's advice? If you have and got nowhere, then it would appear your graphics card is fried and you'll need to take the laptop to the shop for repair.

    When you took out the RAM, the fact that you heard a beep indicates that the CPU and motherboard are both fine - this, to me, sounds like your RAM has died. If you can, test with another RAM module.

    Try connecting an external display and see if it works to be sure not screen problem?

    Restart the computer by holding down the reset button to the left of the Serial port for 10 to 20 seconds.
    Resetting the Power Manager and PRAM
