Helllo everybody!


I have a problem with the red colour on my ecp 4000. When i look

at the red image in the screen setup it´s only sharp at the right side

and gets softer and weaker to the left. Have tried to adjust the side to

side and top to bottom focus but not getting it better. Is it the tube

maybe? thanks in advance..

Could be "fungus" between the lens & CRT face.


When you say side/side top/bottom focus...the mechanical scheimflug is what you adjusted? Using the hex nuts at the front of the CRT? As told to me, these should start at 1" (to give proper range) and only 2 of them should ever be used. The one opposite the corner without one should never be turned...it is a reference poitn per say. What procedure did you use?
