Ok, its one of two things, see if you can bring up the tv menu with your remote, if the menu is distorted or not showing then it’s the DMD board (the brain of your tv) if you do see the menu perfectly then it’s the digital board, probably a swollen capacitor. Good luck.

Definitely the DMD board. Ok, now you need to open your Tv and replace the DMD board, look for the part number printed on the actual board ( like this “P / N : XXXXXX”) then buy it and have a technician install it. Be warn, do your homework and learn about the DMD, so when you go with the technician you have to talk like you know what your doing, otherwise hell try to sell you something else.
As for places where to look for a DMD bard here are some options:

I had the same thing going across the top of my TV , thought it was the lamp. I replaced the lamp and the stripe moved to the left corner. Long story short , behind the color wheel is a small mirrored tunnel , when I saw this, and how the mirrors had fallen in. They were in the same position as the stripe on the screen
