Colored horizontal line on the center of the top screen?
Honestly I think I did something that resulted this issue, two things.
- I tried to fit my unit inside a pouch, to the point that it is totally cramped inside, no allowance for space.
- This might be dumb but I tried to put some toothpaste on a scratch, and I accidentally smudged some of it inside a narrow gap on the top screen, then I tried removing it using a tiny sheet of paper. It was successful, but it looked like the gap got wider a bit.
Then the next day as I opened up my unit, this surprised me. I'm not sure which among those two really caused the issue. Just a straight line across the center of the screen, it's not moving anywhere. I can see that it is changing colors depending on the graphic on the screen, with too much yellow/orange on it. It disappears sometimes without me doing anything, as in rarely, but goes back again.
