Samsung TV Vertical Lines

I have an older Samsung plasma TV that developed some colored vertical lines during the past year.
Most of the time a simple cleaning will fix the problem so that is what I am attempting during this video.
It may work, it may not. It could be a number of other things, I am simply trying something that doesn't cost anything and that anyone can do at home.
Hopefully what you see here can help you if you have a similar problem.
Thanks for watching.

This model is Samsung PN50C550GIF-XZC
The T-Con board is LJ41-C3382A

** UPDATE **
Here is how I eventually fixed mine. If you remove the back panel, you will see all around the outside edge of the panel something called a COF (Chips on film) it is a flexible circuit board that is glued to the panel which is how it makes its electrical connections. The glue has probably let go in one area. To find it turn the tv on and press the film all around the panel until the lines go away. This is the spot where the glue let go. You won't be able to re-glue it but if you put something non-conductive against it so it will always press that spot while the cover is on then it should complete the circuit and the lines will go away. I can't guarantee it will work but it doesn't cost anything to try.
