I have a Panny PT53WXD63, one of last year's models, and there is only the 9-point manual convergence adjustment in the user's menu. Have not attempted the service menu adjustments yet. Working up my courage.
I think the newer Pannys have auto-convergence, but do not know if this applies to the 9-point or 165-point adjustments. You could check if Panasonic has the user's manual on-line, and read about the suto-convergence feature.
Based on your model number, which is probably an older model, it probably has the 9-point manual adjustment in the user's menu.
In case you are interested, Compusa is having a clearance sale this week on certain Hitachi 51" and 53" RPTVs for ~1/2 off the $2000 MSRP. May not be many left (some open stock, floor models, new, etc.). Hitachis seem to have a better rep. than the Pannys. But I love my Panny regardless.
