SOURCE: Picture shows only about a 2-3" blue,green,or red vertical line down the middle

If your seeing vertical line across the screen you need to check the components in the vertical stage as well as the vertical IC could be bad, or the yoke could open.
Also check if any voltage reaching the vertical stage.

Good luck.

Was this help full.

SOURCE: Panasonic TV model CT 27D10B fried by lightning surge

Hi There,

I am unsure as to "where to start looking" means? Do you mean parts to fix it or new TV's?

If you are looking to fix it, you will end up spending a lot more than you prolly want. The surge could have blown a board, Power Supply, fuse, capacitor, transformer or a combination of them all. These TV's are only 27" and if you look on government websites you will see they start the bidding around $5 for the whole TV. If you are looking to upgrade I would suggest balancing a budget that works for you especially with the economic issues going on. 1080p is the latest being talked about, but that doesn't mean it will work for you. I went to Walmart and spend $600 on a Visio HDTV 1080i and I have not had a problem yet (knock on wood). I would not suggest buying a Panasonic HDTV but that is my personal opinion - the majority of issues I have resolved at my full time job came from Panasonic Projection TV's and HDTV. At the same time they were able to shoot out one of first 103" TV's but that just means some tech will have a bigger TV to fix in the future - LOL..

Hope this helps and feel free to rate me..

Happy Holidays..

Try setting a portable fan aimed toward the cooling vents on the back of the set. If this eliminates or reduces the occurance of the lines, this means a circuit that controls the off/on of individual pixels has developed a thermal problem. This circuit is ordinarily loacted on the main circuit board and is likely to degrade further. You might inquire at the Panasonic service center if they have an exchange program in place and they will probably be able to confirm my suspicions.

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.

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.

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.
