hello a have g90 whit all new tubes , if a take a green full screen test pattern, a get a tinny black line in the screen from
right to left, and it becomes brighter on the left side on the screen , this is on internal and external test patterns ,
if a move the test pattern opp ore down it follows the movement, any body have some idea ?


thanks

In Barcos this is called a 'line of coincidence, although I've never seen it in a G90 before. Try zeroing out the convergence settings to 50% to see if you can get rid of it. My suspicion is that you've got one or more convergence settings too far towards the maximum, causing that line.

You probably should reset everything to factory defaults. You can get distortion similar to that with focus settings too.
