Does it black out before windows boots up or after windows has started? Have you updated any motherboard drivers that may have caused the problem? Have there been any windows updates right before the problems started? You could try using windows restore to take the computer back to a state before the screen issue. Try booting up in low res mode and see if it works. Then increase the resoloution up and see if it locks up. A program that is starting up with windows could cause this problem. Check windows start up folder and see what programs are starting with windows and diable the ones you can.

If you have another monitor you can hook that up to the blue connector( VGA) This is usually on the side or on the back. If you get a picture then your internal video might be bad.

The screen on my acer extensa 5420 went black how can I trouble shoot to see what it is?


Good day sir/maam, when your LCD becomes black, the backlight of the LCD screen just went bad. this is caused by the failure of the inverter circuit board and/or lamp, at this point you don't have much choice but to bring it to your dealer for possible inverter replacement, at the moment if you want to see your display, you can plug in an external monitor temporarily. you can activate it by pressing Fn + (locate on your keyboard a picture of a monitor with the same color as your Fn key). hope this helps.

Switch off and on your PC and hold down the F5 key and this should bring up your PC in Safe Mode. If this fails, then find a PC repair shop to replace the power supply.

Sounds like the monitor is overheating. The internal power supply maybe going bad. Ray
