Hi all,

I had vertical lines on the screen like rainbow color and by the time the number of the lines were increased.

I decided to replace the t-con and I found a used one.

Now I have replaced t-con and I can not see the vertical lines, but now the image on the screen appears twice.

Any idea how to solve this?
