Hello!
I'm back with yet another CRT related issue! This time involving a lovely little 15" ADI Microscan M500 CRT I found at the side of the road.
This little guy works, the tube is nice and bright witch is rare these days, but the geometry is off... I can adjust vertical height and position just fine, but none of the horizontal adjustments work, trapezoid and "camber" won't work either. The image is squeezed in the middle like it's wearing a corset and the top and bottom corners are all outside of the viewable area...
And like I said, the required adjustments in the OSD menu do nothing. Sure, I can select trapezoid or horizontal size between 0 and 100, but they do nothing... no change to the geometry.
Haven't encountered this one before... can anything be done to fix it? I rather like this little guy, it would go great with my 286 for older games... My only other small CRT is a 14" Olivetti with a blown flyback transformer so I'd really like to fix it if possible but don't know where to start.
I took the back off, it was pretty clean on the inside. No obvious signs of damage, no corrosion or bulging caps...
