*Knowing* what *should* be on the screen, shine a flashlight
obliquely (so the reflection doesn't come straight back at
you) *into* the screen. If you can see the image that you
*expect* to be there, then your backlight(s) are not operating
(but the panel itself *is*).

Then, use Google to see why that might be the case and what
you can likely *do* about it (assuming you have the
necessary skillset).


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.
