If your display problems aren't the result of visible physical damage, however, the problem
may not be the LCD. If your screen's backlight flickers, shuts down after a few minutes of
usage, or doesn't come on at all, but you can still see a faint screen image, your problem may
be the inverter, a small board that supplies power to the backlight. The good news is that
these boards are available for well under $100. (We'll show you how to locate and replace the
inverter.) If replacing the inverter doesn't solve the problem, the backlight itself may be
faulty. If that's the case, replacing the LCD should fix your problem.
