Answer to "Bright, horizonal lines on screen after water damage. How to fix?"I purchased the tool kit from ifixit, watched many many videos on opening the phone. The task was to replace the power switch and battery. Both the power switch and battery work well now, however I too have the bight lines on the left. One of the videos talked about using alcohol to clean off the glue from the edge of the screen, and I believe this is what caused the damage to the tft monitor. I used 99% thinking if I use 70% or lower it may have absorbed some water from the air which could leave residue or worse. I’ve heated the front and back of the screen (glass side and the copper backing on the tft screen) to help dry out the inside of the monitor but likely the damage is permanent. I’m sure these are not built to be repaired, and using any kind of liquid on the edge of the glass will likely result with this effect, perhaps altering the chemistry of the tft screen glued to the glass. Sad because the phone still works, and using the heat gun on the glass reduced the effect from covering 1/3 of the left...
