    This is normally associated with excessive top or bottom bow adjustment causing the converganece board to work extra hard
    BAck off your bow adgustment to see if it goes away.

    Mike,

    It is a long time since I had a 1020QM but from memory :-
    Bow can be adjusted on all three colours simultaneously or individually on Blue or Red.

    You will first of all have to determine which tube(s) the line is being generated by. Do this by displaying an image which clearly shows the line a white field is likely to be best. now switch off two tubes so that only the green is showing. similarly check the red and blue tubes.

    I have seen this problem on several 1020's. You may also want to shift the image vertically very slightly to see if that reduces the effect.

    In my case I think the line was on all three tubes but I was able to adjust it away. You may find that squeezing the image to get a 16:9 image can cause this effect as well. From memory the effect was much clearer at the left of the image than it was at the right.

    Check to see if the pots that control horizontal and vertical tilt are way off centre. If they are it could be that a yoke has been bumped on a CRT.

    You don't want to go anywhere near the yolks at this stage.

    P.S. you can download a manual here :-

    http://www.crtcinema.com/manuals.html

    It will not be for your exact model but will give some information that may help.

    Good luck

    helipilot - FYI,
    The link to the page works but none of the pj manual links seem to work after that. Many of the other sites listing manuals for download have gone to subscription only transactions. A download typically costs $25 :( I guess it was only a matter of time before benevolence gave way to commercialism.

    Regards
