| Remove the reflector that holds the
bulb from the LCD monitor carefully. Often there
is a soft small clear plastic O' ring that suspends
the bulb in the reflector. If you can not salvage
these you can use a few wraps of a thin strip of
a good quality clear tape. Dispose of the old bulb,
and mount the new bulb in its place. You may want
to cut the end off of the old bulbs wires with enough
slack to splice into the new bulb to match the plug
of the inverter. Reinsert the reflector tray back
into the monitor and secure it as it was originally.
Finally attach the power to the inverter. |

If you have a bad inverter remove
the old inverter from the monitor. Using the new
one you got with the kit, remove the plastic case
the inverter is in with a razor or flat head screwdriver.
Splice the ends of the leads it has to the power
for the original backlight and attach it to the
mounting point the old one was on as best you
can. Often there is a simple way using the original
screws and a hole in the new inverters board.

Before you reassemble your monitor
power it up to verify that it lights up. If you
had to replace your inverter your on screen controls
will not likely work for brightness, but if you
have a half descent video card you can do it in
the video card settings if needed. Finally reassemble
the monitor and reattach the monitor to the stand.

Summary
So for about $15.00 you can breath new life into
that old monitor just gathering dust on your work
bench. Yah there is some risks with the bulbs. But
if your about your wit's should do just fine.

I have received several emails from people who have
tried to tackle this very project with a different
angle. There using ultra bright white LED's. the
claim is that about 10 of them will not only perfectly
fix the monitor, but they last for ever. Now I am
not disputing the longevity of LED's. but I find
it hard to believe that you wouldn't have light
and dark streaks across the screen as the LED's
have a build in lenses that would not evenly diffuse
the light. But for what its worth it's a creative
solution that can be done for just about the same
price. I just recommend that you dump
the inverter if you try it.
Secondly, I have received an onslaught of emails
from people who are wondering if this type of project
could be done to fix laptop LCD's. The answer is
a resounding "maybe". Some laptops use the EL lighting
film behind the entire screen. Others use the CCF
solutions that we have covered. While it may be
possible to do this with most laptops, it is far
more complex with the compact nature of laptops.
So I say its your dime, do what you would like,
either way you will have to tare it apart to replace
it. But for what its worth, when my IBM 760E backlight
went out I went on eBay and got a new one and inverter
for about 18.00. so that's my recommendation for
the laptop users. Look on eBay and if you can't
find what you're looking for then DIY is your backup
plan. . |
