You might have a short causing the set not to start. Probably in the horizontal/high voltage circuit. The buzzing sound that you're hearing is the power supply overloaded. Stargazer

Panasonic CT-36G34 TV vertical deflection circuit


there is a single ic you need to find, usually location ic301 or 401---it will have between 7 and 13 pins in a single straight row---a generic number is printed on the front---usually begins with a LA but can be different

Locate the chip and gain access to the bottom of the board, the pins on the chip break loose from heat==SOLDER ALL THE PINS BACK AND YOU SHOULD BE GOOD TO GO---its a very common problem in these sets.
12_19_2012_7_41_26_pm.jpgsomething like this with more pins possible--will be attached to metal of some sort to keep it cool.

Horizontal lines across TV screen Pansonic CT 35g25


Check its vertical output section circuit for any component damage or loose soldering terminals. Check the solder terminals of the vertical output IC. Resolder all the suspected solder terminals by applying al little more fresh solder, without making any solder bridge short in between adjacent solder terminals.
If this do not help you, replace the vertical output IC. Lose of Vertical Scan is the problem of your TV.

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.

It sonds like bad solder connections on the vertical IC.IF you remove the back flip up the p.c.board and inspect it you should be able to locate the problem resolder it and save repair cost.Becareful of wires and plugs if you have to mark them.

Picture shrinks horizontally every few seconds.


You are changing parts in the wrong circuit. The problem is in the vertical circuit. Look for the vertical IC and resolder the pins first. It should be an LA7837 or something similar. Also, check the 100ufd and 47ufd caps in the same circuit.

Keep us posted.
