On Screen Images don't shows

[valenrr]

I have a Toshiba Satellite L505D-S5983. Win10. I change the AC Jack on the PC. When I start the PC did start, but the screen did not show any image. After three or four attempt turn in off the pc and restarting, the image on the screen appears normally. What can it be?

Well, if you were inside the laptop, it could be that the ribbon cable that connects the display was knocked loose a little, pinched, bent, etc.

You would have to open the laptop back up and check the ribbon cables connections. You may want to even disconnect it and then reconnect it.
