I have an old Fluke multimeter (8022B) which is still serviceable.
Unfortunately, part of the LCD display has a blackened area, which obscures
the =/- signs. The black area is always visible, even with the instrument
switched of. Is there any way to correct this problem? The cost of
replacing the display would be prohibitive, even if I could source one and I
could probably buy another Fluke from eBay quite cheaply.

I once had some success by warming the display such that I made it
warmer towards the centre combined with light finger pressure squeezing
the black out towards the edge. Something a bit hotter than an hair
dryer, but not so hot as a hot air gun is best. I then sealed the edge
of the display.
