Answer to: issue after touch ic replacement. "curtains"I wanted to chime in and say I had this exact problem. It was a dark looking thread bridging C1577 to R2434. I didn't even notice it until I had tried 2 chips, and then found this answer, in a fit of desperation. My problem was almost the exact same. I would get half screen zebra lines, on the original screen, and my aftermarket screens would backlight but no image. If I removed Meson, the original screen would still have half screen zebra lines, but the after market screens would seem to look ok, no zebra lines, and the screen looked good, albeit without touch. I found this thread, and removed it and cleaned the board, and I kept Meson off, and retested. The original screen now works without zebra lines. I am moving on to reballing and replacing the Meson chip. I will edit this if I run into any further problems.
