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.

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.

Panasonic TV without picture


If the sound stays on try just going up and giving it a "whack" on the side, a pretty good one. If the picture springs back to life it is likely a poor solder joint.
Those sets and many others are prone to cold solder around the vertical IC due to the heating/cooling cycles and high temperatures inside a TV. If you hit it and you get a picture back it likely just needs to be re-soldered.

Check the bulbs. If one is burned out, you will get this problem. The bulb is easy to change but will run you about $300.

Vertical line down the center of screen


A WD62827 is a V30+ chassis and is a DLP format projection screen Tv, not a flat screen, am I missing something?? For the symptoms you're describing with a WD62827 remove and reseat the DVI cable between the chassis and optical engine. If removing and reseating the DVI cable does not resolve the issue you may need to replace the Optical Engine part # 938P019020
BTW the current software version for this unit is 7.04.1F if you have anything less you might think about updating the software also..
Hope this helps!

Television has no picture


That TV uses the PTK195 chassis, and the fact that you see only a thin line for each color near the bottom of the screen tells me your vertical output IC has stopped working, and is putting a small DC voltage across the yokes. I have seen this caused by a defective vertical output IC and I have also seen vertical problems caused by a small CRT coolant leak which drips onto the main board near the vertical output IC. If you do not have experience servicing the PTK195 chassis than have a qualified tech handle it for you.
