Panasonic CTN-2056S Convergence off - serviceman mode doesnt work
 

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
