In recent weeks the display on my Lexmark CS410dn has started flashing
a lot - that is, coming up plain lit then going out, repeatedly, or
going out and relighting with detail on it.

Is there a simple cause for this? Something I could check and reseat?
Or, is there some underlying cause I could check for with, say, a
multimeter?

The printer still performs all printing functions as expected, and I
cannot afford to replace it with anything at present anyway.

No idea. Does the flashing have a pattern, like a steady frequency? If I
would assume it was to tell your something. Consult the manual.


I don't know any thing at all about this printer but these types of
queries always peek my interest.
I put 'Lexmark CS410dn' into a google (did you?) and took an Lexmark hit.
In 'Driver & Downloads' it says there's a "Recommended Firmware Update
(August 2019)".
Have you applied that?
Beyond that, wouldn't Lexmark Customer Support be worth a shot?
