Default NAD 510 - dead display

The bulb lights, the display is black. Unfortunately, I haven't the service manual. How to check the LCD display?
The bulbs are supplied from power supply board. Is this voltage (21.5V) used for bulbs only (in display module)?

Supposedly, the NAD 510 service manual or schematic is downloadable from

which is at:

Schematic Service Manual Download Network-

But the server was apparently too busy when I tried.


This place says they will sell the 510 service manual for $5.55:
