no picture in start up

Hello JD421980,

I would be concerned too if my computer screen remained blank after starting up. I found a couple of articles that might help with this.

If the screen is a blank gray screen, I recommend following the steps in this article:

If the screen is a blank black screen, I recommend following the steps in the section titled "No video or no signal, image distortion, "snow," or flickering" in this article:

Thank you for using Apple Support Communities.

Best,

Sheila M.
