I was able to shine a flashlight on the screen this weekend and their
is in fact a picture so it would appear this is a back lighting issue.
Because the screen turns on at full brightness for a split second,
would this imply that the back light has completely failed (and needs
to be replaced) or could there potentially be another issue affecting
this ie power supply, component failure etc?

Look for bad caps on the primary to the inverter.

I was able to dive into this project the other night and did determine
that one of the surface mount fuses is open. I have uploaded an image
of the board he

The fuse that is open is labeled F2. The other surface mount fuse is
labeled F3 and appears to be fine. Can this fuse be replaced by an AGC
fuse ? Is it likely that this fuse failed on its own or there is
another underlying issue with the inverter board? My fear is that a
new fuse will fail immediately after the unit is powered up. Any
suggestions are greatly appreciated.
