David, I am not sure of the differences between your chassis and my
own (CT-27G21U), but on mine, the vertical size is adjusted via a
small pot onboard (IIRC, on the left side of the rear apron). Not sure
on horizontal positioning.

Accessing service mode using the steps found he

However, NONE of the service parameters listed on the site line up
directly, as our TVs are not in the same family. I have identified a
few that affect my own TV, maybe you, or some kind soul with a service
manual, will help fill in the rest...

B0= Sub Brightness
B1= Sub Color
B2= Sub Tint
B3= Sub Contrast
B4= ?
B5= ?

C0= Horizontal Position
C1-C5= Color gun cutoffs & drives

S0-SB=?

M0-M4=?

Hope this helps in some small way

BO'S

This 1999 vintage Panasonic CT-27G24A needs some tweaking to the vertical
and horizontal size. Does anyone know the key sequence to enter the service
mode?

Thanks for your reply.
