Vertical lines

you could have a faulty LCD/t-con ribbon connection, or a failing LCD panel. I would suggest you try and reseat the ribbon cables to the panel and t-con, if you are comfortable doing this!

Tv is about 4 years old. Suddenly developed two

Your plasma screen is made up of 1080 verticle lines and now a few of these lines are not working. This is the screen itself and needs replacing.
