Seeing your pic makes me want to start all over from scratch to see if I can achieve what you did. I am not sure if I can but perhaps disconnecting the conv board might reset convergence in memory and I can try.
Disco'ing the conv bd will NOT reset everything, and believe me that's NOT what you want to do anyway! You gotta build on the work of the factory to get the degree of excellence you want, the kind I demand of each and every display in my cals. A newbie to this will never even come close, if he chooses to be a cowboy and do things in experimental ways, like that.
"Perhaps" is the key word here...
Anyone who owns a nice AV receiver these days and has an elaborate sound and video system knows NOT to just start pressing buttons till it finally comes out right!
That kind of practice is a thing of the past these days, things are far too sophisticated for that anymore, hitting buttons till it comes out right just gets you farther and farther away from your goal.
HD displays are no different.
Even recentering the point sys at all points doesn't work on a Pio, like it does on a Mit. They are all a bit different, and I know exactly how to correct what you're talking about to the highest extent possible. And resetting it all - clearing all settings back to some master starting point on the assembly line - is NOT it.
For instance, you'll never get the hor lines to ever be perfect at the very ends at all points on the screen. Most of them will always slant a little up or a little down at the very ends, and o'scan redux doesn't help any - tho it's highly worth doing anyway, for the incredible good it DOES do, on other levels. You can only get 98% there at the ends of the hor lines, it's endemic to the genre. Ceiling pjs can get it right, but they were designed with a WHOLE lot more capacity for such things than the pricepoint of CRT RPTV ever allowed for.
And the last 3-4 vert lines on each side need VERY special handling.
Took me years to learn exactly what to do, but now it's second nature and takes no time extra at all, over and above the time and attention I give each display in all my cals, when the unit is still fresh OOB. If it has been worked on and the problems are inadvertently exacerbated before I get there, I make no promises other than yes I WILL get it back to the garden, tho it may take a little longer...
IOW, you don't want to be messing around with your display uncarefully or experimentally, if you expect the best pricing on my calibrations or those of any other pro...
