This undoubtedly means there is a fault. Try turning the power on and off again, and if that does not fix it you will have to call out a repairer.

I would suspect a problem in either the backlight assembly, or the power supply that drives it. If it's the power supply, the part may be over $100.

The problem may be in the wiring which if you pull up the carpet on the front passenger side by
removing the door floor trim and lifting the carpet you will see the
wiring underneath. Probably laying in water or has been. Look for splices in the
wiring which will have corroded. Repair the wiring then check the fuse.
Another problem may be in the motor found inside the door.
The brushes may have worn out. If so you need to replace the motor.
Ususally the drivers side will fail first since it is the most used.

Cause of power going
off: There is a bad 1000uF, 16V cap
on the power supply board.
Solution: Replace cap. Radio Shack sells a 1000uF, 35V
cap for $2. This will work.
Why did the cap go
bad? The cap is too close to a heat
sink and over heated.
What does this cap
do? This cap sends a signal to an IC
which keeps the monitor 'on' after the power switch is pushed. When the cap is weak, AC ripple voltage is
applied to the IC and it sends a signal to shut the monitor off.
Opening the Monitor:
These monitors are difficult to open.
The two plastic pieces snap together and must be pried apart
with a flat screw driver.
After removing the stand, you need to insert a flat screw
driver at the bottom of the screen where two slots are located. Then work the screw
driver around until the two plastic pieces are separated.
Remove the cover plate and unscrew the push button circuit
board.
Unplug the monitor cords from the driver board and remove
the screen.
Unscrew the mounting screws from the power supply board and
remove.
You will need to pinch the plastic support in the middle of
the board to remove.
Cap Replacement:
Cap is located near a copper heat sink and the value will be
on the side of the cap. It will be bulged up on the top. You will see burn
marks on the board surrounding the cap. Unsolder the cap.
Install the new cap and solder. Make sure you connect + of
the cap to + marked on the board.
Be careful not to solder across joints.
Keep leads long so you can bend the cap as far away from the
heat sink as possible.
Reassemble monitor and turn on.
This should solve the problem.
