Re: panasonic CT-27D30B

Put a voltmeter on the vertical I.C .
pin 1 should be 12Vdc
pin 2 should be 24Vdc
from those two inputs, it should be generating at least 50V on pin 13.
If those are not present, trace the power back to its source in the flyback circuit, where a resistor or diode has blown.
If present, check its output on pin 12 and if there, trace through the vertical output circuit.
If not, it may not be getting a trigger pulse from the main video chip.
Hope Ya Fix It!

Why I have a thin line across the screen in my TV model Panasonic TC 21. After replacing the vertical IC the horizontal line across the screen reduced to few inches and not as it was earlier. vertica

First, You should to replace by original part, then you should check the voltages on power supply, and check the voltage for vertical IC based on datasheet, also check the voltages on vertical section including yoke and last you should check the ESR capacitors on vertical section.

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!

Tv screen is black except for 1 horizontal line of color

The line is there because the vertical deflection unit - the one that spreads that line across the entire screen to form the image - has failed. Replacing it is a job for a professional, or at least an experienced amateur, and the parts will be quite difficult to find for such an old tv .

Tv vertical

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.

Horizontal white lines across top of TV screen

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.

Your vertical output IC has stopped working. This is usually caused by the solder joints cracking loose and the IC will either short out inside or just stop working. Sometimes a small capacitor next to the IC, called the pump-up cap, will go bad and cause the IC to fail. In any case, the vertical output IC should be resoldered or replaced and all circuits checked by someone experienced in repairing TV's.

Tv not working

this symptom, sometimes called the tube light effect, it is characterised by a bright thin horizontal line across the middle of the screen. this symptom is caused by a breakdown in the vertical deflection circuit. hence maybe the trouble maybe in the vertical oscillator, amplifier or output circuits. but if all i have said is not clear to you, better bring it to a qualified tv technician. good luck!
