Panasonic CT-27G24A service menu.
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. -- David Farber David Farber's Service Center L.A., CA |

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 http://www.calanan.com/panasonic/ 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 On Tue, 2 Aug 2005 15:01:19 -0700, "David Farber" wrote: This 1999 vintage Panasonic CT-27G24A needs some tweaking to the vertical and horizontal size.

Hi Brian,
There are no pots anywhere in this set except for the screen and focus controls. I've visited the link you included and not seeing a match between model numbers, I decided it would be better to wait and see if could get the information for the exact model. The TV is really not so unwatchable as to muck it up adjusting the wrong service parameters. Thanks for your reply. David Farber Brian O'Sullivan wrote in message ...
