Default lcd monitor problem

Here are some links to help you out..

This appears to be a quite long article, but has no pictures which makes it
not so good.

The stright bulb on this page looks like your typical ccfl lamp.

You can buy ccfl lamps at www.mouser.com or
http://www.lcdpart.com/ (they have instructions on how to do it with
pictures)

Yet another article..
http://inventgeek.com/Projects/Backl.../overview.aspx


Just google LCD backlight or CCFL backlight.

You can somtimes find free service manuals for whatever monitor your working
on at http://www.eserviceinfo.com/


One word of caution if your changing ccfl lamps.. They BREAK VERY EASY if
your not careful.

Well there isn't much to most LCD monitors from my experience.. I've just
started reparing them recently and most problems are related to bad
capacitors or bad lamps.

The reason you don't find much info on them is there isn't nearly the
amount of components inside one compared to a CRT monitor. Usually all
they have in them is an inverter board wich powers the flurescent lamps
in the lcd panel and a control board which handles video signal
processing..

Possibly a bad VGA cable of bad ccfl lamps.

I'd bet on VGA cable.
