filter caps seem ok (based on ripple on scope)
still having problem with getting a full horz scan. I checked the HV with the crt bias fully CCW to have zero beam current (I assume that is how to have zero beam current, crt was dark) checked HV was right at 30kv. Schematic says should be 26k max, so I adj horz bias to get back to 26kv. adj CRT bias to get normal CRT brightness back, and now short on horz deflection again.
argh..
there was not 5.6k resistor in the yoke path, AND the Flyback has a trim pot inside the HV cage that has an access hole on the side of of the cage. This is NOT in the schematic and there is no marking on the cage saying what it is for.
I am wondering if it could be a horz width control.
This purpish line is def related to scan width, when I change the format on the converter box to a smaller view (margins on all sides of the programming) there is no issue with the purple in the image, only when the image extends the the end of the scan does it show up. the green is just not scanning quite as far as the blue and red guns. If I could get it to do the normal amount of over scan the issue would be gone.
Seems odd that you have to rely on the HV to be set over max to get the correct scan.
I am going to monitor that HOT current and try adj that pot in the cage to see what it does. Noting the starting point of course.
