After closely looking at the laptop screen, if your see a very faint image,
there is every possibility that the machine’s LCD lid close switch is stuck
in the closed position. If this switch is in closed position the backlight will
stay off, even with the LCD lid open. This is meant for conserving power
when the laptop is on while the LCD is closed. Check this switch located
close to back to which the LDC hinges. Tap the switch and see whether it
helps to restore the screen backlight. If it does not help, try replacing the
FL inverter board. Erring inverter can also be the culprit behind dim display
and you may need to replace the faulty inverter.
Screen is solid white color or garbled
After connecting your laptop to an external computer monitor, you will be
able to determine that your LCD screen or the LCD cable connection is not
functioning, if the external monitor functions properly. On the other hand
if the external monitor functions same as your LCD screen, the problem
can be attributed to faulty integrated onboard video, which would require
replacing the motherboard.
