Well people, laptop screen repair will be something you will no doubt need info
on at some point in your laptop's life... The symptoms are that the laptop display
panel will flicker and then appear to switch off, but if you look closely you can still
see a very faint image on the panel, almost like peering through the dark, this is
because the backlight isn't lit.
Inverter boards have been an issue in a lot of makes and models of laptops – this
is a very common fault. The inverter board loses proper connection causing the
backlight to flicker or just simply fails altogether.
A little info in what we mean when we say 'Back Light'. Your screen has a
fluorescent tube inside it which is just like your normal household tube except for
its size, it's about 1/10 of the size. The tube is attached to a small circuit board
via a cable, the circuit board acts like the starter in your household variety. This
circuit board is called an 'Inverter or FL Inverter', the inverter provides regulated
power to the fluorescent tube which lights up the screen.
If the Inverter fails then you appear to have no display, yes and no, the screen is
still displaying the image but without light from the tube it only appears ever so
faintly.
