Hi martin,
Congratulations, that’s a terrific calculator to receive as a gift! The
high anode voltage required for the display
is generally provided by an inverter powered by the DC input. From the
pictures, it looks like there is a transformer
just behind the display. That is likely for the inverter. Look for small
electrolytics around that transformer, especially
ones that have high operating voltage values. All those should be replaced. The
yellow ones in front of the display are
probably OK if all digits are visible. I love these kind of calculators and
hope you get this one in working condition.
All the best,
Rich
