The internal video circuitry on the system board is bad. This requires a new system board to fix the problem.

If your laptop screen is not working and is blank, you are out of luck as far as working on your computer. However, while there may be a major problem you need to troubleshoot, there are some easy solutions to keep in mind as well, such as brightness settings and your power source.

1. Check the power source. While you have presumably already attempted to turn your laptop on and off, the problem may lie with your AC power adapter. Is the power-indicator light on the adapter on? If not, your problem may lie here. However, whether or not you have a power indicator light on your adapter, consider unplugging it and plugging it into another outlet. This may turn on your laptop and take care of your blank-screen problem.

2. Check your brightness settings. While it seems like a simple oversight, the brightness on your laptop may sometimes be turned all the way down. Thus, the screen appears to be black, off or defective, when the problem is simply that the brightness is on its lowest setting. To fix the brightness, check your laptop keyboard. Most laptops have the brightness settings mapped to two keys at the top left of the keyboard, accompanied by a symbol (often a sun). Use these keys to fix your brightness, but keep in mind that some laptops require that you press the Function key at the same time as the Brightness key.

3. Check the status of your laptop battery itself. There should be a battery indicator on the laptop that is connected to the battery. This indicator is either on the bottom of the laptop or (likely) on the side. If there is no indicator, your battery itself may be the problem, and may require replacing. Keep in mind that older batteries of the nickel-cadmium variety are more likely to decharge over time and forget their initial maximum charge level; this may be a particular issue to users of older laptops.

4. Find a VGA connector and hook up your laptop to an external monitor if the above steps have not alleviated the blank-screen problem. Turn on the computer and the external monitor. Does the external monitor light up? If so, the blank screen is likely due to a video subset problem/LCD problem in your laptop.

5. Consider that a deeper problem may exist if the external monitor did not light up This problem may lie in the motherboard. In this case, taking the laptop to a professional repairman or sending it off to the manufacturer is recommended.

I hope you find it very helpful. Best regards from fixya

Blank screen


Try plugging the laptop into an external monitor to make sure the laptop is booting up properly. If it is unplug the monitor from the laptop; or if you know the laptop boots up fine and you get the windows audio when it boots and the initial starting beeps then forget the monitor. Shine a torch or light source on the screen and if you see a faint picture then the inverter on the screen has developed a fault.

My srceen goes Blank


Hi,

first try booting the laptop and pressing the Fn key with the numerical ( numbered key ) that has a picture of 2 screens on it. This is for booting to an external monitor. you could also try adding an external ( pc monitor ) this will eliminate any motherboard Faults.

Secondly, the graphics chip driver may be corrupt or not installed correctly. if you have a restore cd, you could try booting the laptop, with the cd in the drive.

you can then try, to see if the settings in the bios are all correct, by booting/starting the laptop and pressing esc or F2 or delete immediately as the laptop starts. ** Be-Careful** what you adjust.
My suggestion is to look for. ** default settings tab** or load setup defaults.

these are the obvious things to try, before assuming that you have a faulty graphics chip or motherboard fault.

I can turn my laptop on but the screen is black


Hi,


Do you hear a beeping sound when turning it on? Try connecting an external monitor (Desktop monitor) then press FN+F8 (Dell laptop only) and FN+F4 (HP laptop only). If it works on an external monitor, you may need to contact your computer manufacturer. check the warranty and request for an LCD monitor replacement.

If you hear a beeping sound when turning on your laptop or no power (no light). you may need to reseat the memory (RAM) or check the AC adapter (power adapter).

Let me also know the system model and computer manufacturer.

Keep me posted.

Thanks.

Hi, I have an Acer Aspire 5920G. My problem is when the laptop is switched on it sounds like it's booting but the screen stays blank? Have you any idea what can cause this? Regards, Dan Pook...


Hello
I think your graphics card or screen is broken on your Acer Aspire 5920G, one thing you can test is to connect at external monitor to your laptop. If you dont get any picture then its your graphic card broken, if you get picture it is your screen. also try to adjust the screen light.
