I've got an old mitsubishi diamond pro 19" that's starting to lose focus. Everything is getting blurry / fuzzy. Is there any way to correct this or is it finally time to ditch it?
Most CRT's include a "master focus" pot inside the casing on the PCB that you can adjust with a screw driver. However, usually it is already set to maximum from the factory unless it had been dislodged from transport or something.
Usually the loss of focus is because the tube is aging and has lost some of it's magnetism. And in that case there is really nothing you can do about it.
