Laptop white screen


Having a laptop screen turn white is one of the most frustrating problems a user can experience since it prevents use of the laptop to find a solution.
A white laptop screen indicates a serious problem with the laptop's hardware, and no easy solution to this issue exists.
Just diagnosing this condition requires advanced computer knowledge.
Identification

With this problem, the laptop itself will power on and load the operating system as per usual, but the screen will become a complete, static white, according to LaptopRepair101.
No particular brand or make of laptop falls prey to this issue more than any other; it can happen to any laptop.

Causes
Since so many different brands and models of laptops exist, specific causes of a white screen vary from laptop to laptop.
The likely cause in most cases of a white screen on a laptop is a connection problem between the LCD screen and the video cable running from the motherboard.
The issue can also reside strictly with the motherboard or the screen might contain a defect.

Considerations Users can diagnose a white screen problem by opening up the laptop display case to determine whether a loose video connection on the back of the LCD screen exists.
Reconnecting the video cable should resolve the white screen; a video cable reconnection that does not fix the white screen narrows the root cause to a problem with the motherboard or the screen.

Motherboard Problems
The only way to determine if the laptop screen turns white due to a motherboard problem is to test out a different, working LCD screen with the laptop.
This requires the user connect the inverter board--the power supply for the LCD backlight and the video cable to the test LCD.
If the test LCD works with the motherboard, then the laptop's screen needs replacing; otherwise, a new motherboard is needed because there is no way to replace an integrated graphics card on a laptop motherboard.

Prevention/Solution
Taking apart a laptop screen may make some users feel uncomfortable, so you can use an external monitor connected to the VGA port common to most laptops if the processor and hard drive still work fine. Using an external monitor requires finding the proper function key command to toggle between the LCD and external monitor.
Warning
Taking apart the LCD screen on a monitor likely voids any manufacturer's warranty.
Consider visually checking the video connection to the laptop screen as a last resort if no other viable options exists.
The service manual that came with your laptop likely offers some tips to disassembling the computer, or conditions that could void the warranty.

CPU powers up, mouse comes on but there is nothing on the screen


Have you got another screen you could connect it to? If you have then that will show you where the problem lies, for instance, If the external screen works your laptop, then your screen is faulty and if it doesn't you will be looking for a system fault in your laptop.
Does the BIOS screen work? If it does, re load your screen drivers.

Where should i go to get my screen fixed? i dropped my laptop and now the bottom right corner is cracked and black.


Unless you purchased an "all-perils" warranty when you purchased your laptop, you'll have to pay a qualified technicican to disassemble your laptop, remove the LCD screen, order a replacement screen, install it, reassemble your laptop, and test that it works.

Say $200 for a new screen, and $75 for "labour".

No power on laptop screen


Hello,
The first thing to try is to hook up an external monitor to the laptop.
If the external monitor works then it is either the LCD screen or the backlight for the LCD. If not then it is probably the video card inside the laptop.
Also check the "function" (Fn) key combinations on the keyboard, you might have shut the screen off with the Fn keys accidentally.
Hope this helps.

if nothing is displayed on your screen then we have two options and they are:
1. try and connec an external VDU to your laptop and power up again
2. Check out the RAM and replace it with new ones or certify its working capability on another laptop.

Gateway flat LCD dead


I'm not sure if your referring to the lcd monitor (gateway brand) or a laptop's lcd screen not working anymore.

1. if it's an lcd monitor...
a. test monitor in a different pc before assuming the problem is the lcd screen
b. replace the monitor if after testing monitor is in deed the item failing.

2. if it's the lcd screen from your gateway laptop.
a. you may be able to attach a regular analog monitor to the paralel port on your gateway.. test and see if the monitor that you attach will give you a picture (you may have to toggle with some some keys on your laptop keyboard to make have the signal going to the "externa" or attached monitor.
if the other monitor does not work either.. you video controller on your motherboard on your laptop may be failing and you may not have other options that to replace your laptop.
b. if the external/attached monitor works.. very likely the problem is the lcd screen for that you need to get a replacement and you may have to contact gateway to find out about pricing (or places to send your laptop for service if you're still within warranty). if you have an old laptop you may have to considere simply replacing the unit as buying a new lcd screen may very likely be more expensive than the same working laptop.

Problems with My Monitor Screen.


Hi,
Sony vaios are very tempramental.
Did you drop or bang the machine, before this happened ?
There are a few suggestions.
1:) the screen catch mechanism is jammed.
Solution:- turn on laptop, using a small blunt screwdriver. where the laptop latch, goes into the laptop base. gently push the latch mechanism a few times, to see if it,s jamming.
2:) if the screen display shut off mechanism is under the actual laptop screen lid, push the small plunger, up down several times.
These are common likely causes.
3:) press and hold the power on button for 15-30 seconds, this is in case the system has gone into hibernate/sleep mode.
4:) ensure The battery is fully charged. And the laptop power supply is plugged in.
If none of the above work for you, you may need to take into a repair specialist.
