1. Could be turned off in the menus.
2. Maybe bad solder connections at the display tube. Fairly common.
3. Missing filament voltage or -30V power supply.
4. Bad driver IC
5. Display tube broken or otherwise bad.
6. Other?

Hi,
I'm looking for pointers or a schematic of the front panel
VFD drive electronics for a Panasonic DVD-CV51.
VFD appears dead. Player works fine, otherwise
(including the other front panel buttons and LED indicators).
While the display isn't crucial to the operation of the
player, it's kind of irritating to know that it *should*
be illuminated, yet isn't! :-(
Any help would be appreciated!
Thanks!
