Which of the following failures can cause a system to have a very dim display only visible when you shine a flashlight on-screen?
a. Inverter failure
b. RAM failure
c. Incorrect display input
d. CPU failure
A If you can see text or graphics with the flashlight, the backlight subsystem on the display has failed. On an LCD-CCFL, check the inverter first. Inverter failures are much more common than fluorescent backlight failures and are relatively easy to replace. On an LED display, check the LED driver first.
