I've been trying to sort out an MTC 9000 and I'm a bit stuck - not having played a lot with raster monitors!
I seem to have a decent sized image, but there's sh*te all over the screen, but the image is there, controls such as sync and size all work.
Since a few of the caps had a high ESR I changed the lot but no change ..
Pic of screen here ..
I've had a quick look at TR18 and it's pulsing, not shorted! It feels to me like it's the blanking circuit, but mainly 'cos I don't know where else to look!
Any hints of where to look next?
Thanks!
Steve
