Some days ago, a customer contacted me about her laptop displaying just white/being blank upon her swotching it on after she used it a night before and i wasn’t surprised because electronics gadgets are prone to develop fault at just any time.
I took the laptop to my office for troubleshooting to discover the fault. In this tutorial,i will be exposing us all to common laptop module-less screen fault and the possible solution.
1. Whitish or blank screen: It commonly among Hp laptops and this fault develops when the laptop is not properly taken care, or when one forcely unplug the charger from the socket.
Most times when the problem occur, the screen and the VGA are not the faulty but an VGA IC on the motherboard is faulty.
My advice is dat not all laptops engineers can work on ICs so it adviseable you take it to an experienced laptop engineer
2. Line on the screen and probably the pointer of the mouse is not moving as the pace of the controller: When you experience that your laptop generates lines on the screen,it better you prepare your cash to buy a new screen.
3. Screen not displaying: After powering the laptop and the indicator signals that the system is booted up but nothing display on the screen. Either the VGA cable is is not properly plugged or an IC on the motherboard has gotten burnt
4. Screen displaying an irregular colour: When you notice that the background colour of your laptop changes from white to either blue or red,you will have to trace the fault to the VGA port on the motherboard.
As we advance, a new fault arises but if you detect a screen fault that has not been listed above with your laptop, used the comment box below or for quick response,send us a message using the livechat on the blog.
