suspect it's 1 or a couple of bad capacitors in the vertical deflection circuit the caps are in the 400 series, c400,c401,c402, etc... check or replace c414,c418 & c417

Vertical hold circuit is failing.

Check capicitor in vertical hold circuit. You should have solid knowledge of electronics repair before attemping repair. TV's can emmit harmful radiation, and produce voltages up to or in excess of 30kV.

Hi I had the same problem. Broken white lines across the top of the screen. This is called overscan. You need to go into the Setup menu, other settings. 16:9 overscan needs to be on. Hope this helps.It solved our problem.

My panasonic ct-32g6 has a horizontal line through the middle i can hear the sound but all that comes on the screen is the horizontal line.what is the problem?


The fact that there is a horizontal line on the screen tells you that all circuits are in operation except the vertical circuit , The virtical IC is probaly shorted or the reisitor that supplies voltage for the fly back is open in addition the negative feerback from the signal processor IC can be open also which can cause a horizantal line .You will have to check all dose circuits to seewhat is causing the line

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.

Panasonic CT-27L8SG displays gray screen and white hoizontal line


Is it still under warranty?
If not I would find a good TV Service Shop and have them check out the power supply as there more than likely a 'Capacitor' much like a battery that is going bad.
