I've had the display section of a laptop apart, and on reassembly theinvertor, check the capacitors around the transformers, also check the 2
screen backlight died a few seconds after switching on. A bit of work with
a multimeter has shown that the fuse on the inverter board has blown.
Bypassing the fuse with a piece of wire (temporarily, of course) causes
the backlight to flicker on for a fraction of a second when the laptop is
switched on, then all goes dark again. Obviously something somewhere has
broken, but before I splash out on a new inverter board, is it possible
that it is actually a problem with the backlight itself? Should I instead
be looking to replace the display panel?
drive transistors that are around the same capacitors. Often the
Capacitors have failed, causing the transistors to die. then the current
increase blows the 2A SMD fuse links.
