Service mode entry, adjust and exit procedure to many popular brand TVs are given. Never forget to exit the service mode, after all adjustments have been done.
NB: Please read and understand well, the instructions to enter the service mode, before you begin. Be very careful. Note how to "EXIT" the service mode; after entering and adjusting data. This is very important.

Which service manual setting controls horizontal size?


You're discussing about the factory mode adjustments. The horizontal width adjustments will not be there. You have to adjust it by replacing certain capacitors at the horizontal output stage.

It appears that the image on the screen is zoomed in, but I can't figure out how to "undo" that. Thank you!


If the image on screen is zoomed both in vertical and horizontal direction, your TVs power regulator inside it is faulty. [Overvoltage]. If it is zoomed in vertical direction only, that is only the height of the picture is zoomed, you can adjust it with the remote control button directly on going through menu and get in to the function menu. Normally all TV remote has a special button marked as "Zoom" which on pressing it once the picture get zoomed, again another press the picture gets wide and again an another press picture will come to normal mode. You should select normal mode to retify the problem.

Our tv, a Panasonic # CT-36D11E/CT-36D11 only shows a horizontal thin line across the screen. The sound is fine - any ideas? Is it time to replace or could it be repaired cheaply?


Resolder the vertical IC and replace those capacitors near and next to your vertical IC. If the horizontal line still appears, you may have to replace the IC. Thanks for asking and be caredful!

Panasonic CT-27SL15 has scan lines on top 4 inches of screen, what is problem and how to fix?


Nov 2011 - Comment
Have similar problem on a Panasonic Tau model CT-27SL15.
It's a 27" CRT TV manufactured around 2005.

Other posts / solutions on this problem say possibly a capacitor going bad in the vertical circuitry / near the vertical IC / vertical blanking circuitry. Telephone call to a TV repair person mentioned something similar - "possibly a bad capacitor in the vertical circuitry".
Found a service manual online w/schematics and board layouts.
Panasonic Service Manual
http://dl.dropbox.com/u/35219914/PANASONIC%20CT27SL15.pdf
See pg 25 (of 42) - Deflection Schematic Diagram (Main PCB)
Shows: V Output IC - IC401
Finding the actual bad component(s) may not be so easy.
Anyway ... just wanted to add this comment.
