Flickering at bottom and top of lcd with blacking out on screen


Answers :

Hi
\015\012
\015\012Thank you for your query
\015\012
\015\012From what you are describing it sounds like the riboon cable or the inverter of the LCD screen may be at fault
\015\012
\015\012Please try the following
\015\012
\015\0121) Switch on the laptop
\015\0122) Repeatedly press the F8 key until a start upmenu is presented
\015\0123) Choose safe mode from the menu
\015\0124) Once in safe mode see if the above occurs
\015\012
\015\012If it does then you have a hardware fault on the screen and this will need to be investigated further by a competent Laptop engineer
\015\012
\015\012If it doesnt then it would seem the fault is software based and i would recommned that the VGA driver is removed and reinstalled, by doing the following
\015\012
\015\0121) Stay in safe mode
\015\0122) Click on start>Contrpl Panel>System> (Tab) Hardware> Device manager
\015\0123) In the device manager window there will be a small + next to a title called display adapters, click on this plus which will open up the vga drivers
\015\0124) Right click on this driver and click uninstall (note: there may be 2 drivers in that case click on both and then click uninstall)
\015\0125) The Laptop will ask you to restart follow the on screen instructions which will take you back into normal windows and hopefully this would have cured the fault
\015\012
\015\012If this has been useful please leave postive feedback/vote/testimonial - Thank You Again
