Hi,
I just replaced the backlight on a pair of Hitachi screens. Not for the
faint of heart.
One works fine, and the other doesnt, so YMMV.
You will need to purchase a replacement backlight, and then take the
seperate panels out of the frame (after taking the whole LCD panel out of
its frame.
Then you unsolder the old backlight CCFL tube, and solder the new one in
place. Then reassemble them all together, making sure that every panel lines
up correctly. Then when you put the copper tape back on, you need to make
sure that there is a good ground (that is where I think I messed up the one
that doesnt work - poor ground, but not sure...)
