Display getting distorted and goes white blank at times

I hv been using Thoshiba TE2100 for the past three years without any problem. Now the display gets distorted with jerky lines and losses the sync completely. Some time it goes balnk white. I hv to forcefully turn it off by holding the power on button on the laptop to shut. When i start again it works and same problem after some time. I observed alos that when I tap near the display it settles down some time. May be a loose connection? Pls. help me on this one.

It could be a problem with an internal connection. A quick test and perhaps even fix would be to grasp the right and left sides of your display while it is on (displaying the offensive lines) and gently twist like you were wringing out a towel. Again, and I emphasize, gently using only a couple of ounces of force. Watch to see if the lines disappear, get worse of make the screen flash or change. If you do then its likely cause is the connector from the LCD panel to the electronics has oxidation or a loose connection. If you?re lucky the flexing might even fix your problem, if not you will have to take it apart to find out exactly what is going on.

Display Becoming White

First, to verify if it is your display adapter, connect an external monitor to your laptop and see if it displays fine. If it is fine on the monitor, then we know that it is from your laptop screen(in this case, it is either you first check from a technician if it is the colour that has to be refilled or if you need to purchase a new screen). If not then it is from your display adapter(could be from corrupt display drivers). In this case, you would have to re-install new drivers for your display adapter(you can download it from your system manufacturer's website if you don't already have it).

It sounds like your Operating System is gone. Try to run a repair by pressing the proper key that kives you your comuter's booting options. If that doesn't work, then probably reinstalling your operating system will fix this, as it has fixed the same problem for me in the past. Thanks

You have a either a bad inverter (which lights the screen's tube) or a broken tube. that'd be my guess.

Try this: shine a bright light on the screen from the side - if the light is hot be sure not to be too close or the screen will melt - and see if there's any image on the screen. There should be...

Try holding the Fn key down and then press the F5 key a few times, waiting a few seconds each time to give it a time to switch between display modes.

Acer Travelmate 6291 LCD monitor problem


Your concern is a typical problem with LCD displays/monitors. There could possibly be three (3) reasons why it is behaving as you have posted.
1. Backlight/Inverter problem;
2. LCD panel problem;
3. Video card problem.

You can do initial diagnosis by:
a. connect the laptop to an external monitor. Using the Fn + F? keys, activate the external monitor to be the default display. If it works, you have eliminated the possibility of the video card having a problem. If it likewise did not display anything or blanks out after sometime, then you have just confirmed that it is the video card that is a problem.

If you have ruled out the video card (using above procedure), you can proceed determining if it is an LCD panel problem or backlight/inverter problem.

To determine if it is a backlight/inverter problem, run the laptop normally even without a display. Let it boot and run through its startup sequence even if you can not see anything. Using a flashlight, shine a light obliquely to the face of the LCD display. if you can see some semblance of your desktop albeit dark, then you have just confirmed that it is the backlight/inverter. If even with the aid of a flashlight, the display s completely blank, then it is possible that the LCD display panel is defective. In some cases it is the flexible flat cable that is at fault.

With any of the aforementioned possible problems, opening the unit is required. This would need familiarity with electronic components and circuitry, use of a DVM and perhaps even a soldering iron. Should you not be comfortable doing this, it would probably be to your best advantage to seek the services of a qualifiedly professional.

Hope this be of some help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Screen problem

Perhaps your connections on the inside have come loose. It may warrant you take it to a specialist to check it over before it gets any worse. Some other person was on here some time ago who had a similar problem and all it was is the switch in the lid. Apparently they tinkered with it by just kept on pushing it back and forwards as if to continue to open it and it came right they tell me that they hardly used it thats why!.
