Screen goes black after tripped over the power cable

My granddaughter tripped over my power cord on my Compaq laptop now my screen shuts down like after I start it the screen goes black. If I touch the display switch I can not see whats on the screen. If I angle it right I Can see my Windows screen. Think I should get another switch and replace it? Or any one got any other idea what to do?

I doubt your problem is related to the display switch.

From your description it sounds like the laptop has either failed inverter board or failed backlight lamp inside the screen.

If the laptop was dropped, probably the backlight lamp was damaged. It means you’ll have to replace the screen because the backlight lamp mounted inside the screen.

If I would have to fix the laptop, I would probably go though the following steps:

1. Test the laptop with an external monitor, just to make sure that external video still works fine. This will confirm that your video card/motherboard operate properly.
2. Reseat video cable connectors on the motherboard, LCD screen and inverter board, just to make sure it’s not just loose connection.
3. Replace the LCD screen and if it doesn’t help, replace the inverter board.
