Magnavox stereo problem

I've got a fairly recent (maybe within ten years or so) Magnavox stereo.
All that's wrong with it is no panel display. I have disassembled it,
and ignoring my chagrin at being faced with such a poorly designed item,
it appears that the problem is NOT lamps.

There are no lamps. It appears that all the displays are LEDs, which
points to a power supply issue.

Does anyone have access to a diagram of a unit like this? It's a cube
about 15 inches on a side, includes a turntable, CD player, and two
cassette units (run from the same motor!), plus the usual AM FM radio
with presets and a remote control.

I believe the model number is AH197.

Thanks in advance to anyone who can help.

Definitely LEDs and not a VFD ?

The service information parts list shows the display lamp Part #
482213440965 for the AH197M NAP stereo. Are you sure you looked behind
the display?

Well I will take another look. The display is soldered in. But there
is plenty of space under it.

Further, there is an LED timer display that doesn't light.

Any chance you can scan the appropriate part of the diagram for me? It
would make life a lot simpler. My troubleshooting skills are inhibited
by lack of information.

Manual# 1735, approximately 1991 vintage.

Tuner/function display is an LCD with a 12V 150mA LAMP buried behind it
soldered to the PC board. 4822 134 40965 probably NLA unless you find
one collecting dust on someone's shelf, substitue anything that will fit
with similar current/voltage rating.

CD display is LED's driven by the CD player's 5V supply, and should work
as long as the CD works, barring wiring failure.
