If this is the standard 20 inch set that I think it is, there are no
convergence controls in the service setup for your set. The bottom, top, and
sides are done with adhesive slip magnets that are mounted on to the CRT
bell, and extend down in to below the yoke windings. You may need additional
magnets from the ones that are already installed.

The ring magnets on the back of the CRT neck only do the main centre
convergence and purity. I strongly suggest to not mess with these ring
magnets, unless you have a lot of experience, and the grating test
generator, to do the proper setup with this.

Most of these sets will have a convergence error of about 1 mm to 2 mm at
the extreme sides, and top and bottom of the screen. The centre area
convergence should be about 1 mm or less error.

Guys,
I've got a 1992 Panasonic 20" TV (model: CTN-2056S Chassis: AEDP213)
- the convergence at the bottom of the screen is off. Does this unit
have a "serviceman mode" like the newer panasonics? I've tried the
normal "cable, timer=30, volume=0" but this tv wont even go to channel
124 (max is channel 99).

How can I get into the menu and/or adjust the convergence?
Thanks,
--Eric
