OK...maybe a bit more info. While I did pay heed to this warning, I was using a universal remote when I was adjusting the convergence of the set. So, anything could have happened. Does anybody know anything about this? This may be my problem...

Convergence Tips
<< Back to Service/Designer Menu Page
Tips from Mr Bob:
TIP 1
"The 9 point convergence is the worst, and causes hourglass-shaped convergence errors that cannot be remedied via the 64 point. When ready to do a 64 point, you have to either straighten out any discrepancies caused by the 9 point, or find the 6 settings in the designer mode--the STC's, I believe--and recenter them. I believe default setting is 80 on each.
Whatever you do, DO NOT UNDER ANY CIRCUMSTANCES order up VPOS and hit Volume Up twice. If you do, kiss your S-video inputs bye-bye.
If you need to raise your picture up a little, do so ONLY from being in Designer mode, NOT in Service mode."
