I have a 5s a customer brought in w/ severe water damage to lcd flex area and no power. After I went through my usual regiment of solvents, the mobo is now clean(See before and after pics) and it powers on. Everything works except there is no image on LCD. I have tried the original, along with 2 brand new LCD’s, but still no image. It may be the backlight, or whatever controls the LCD image. Anyone have a schematic and no which I should start with? Where can I get the chips? Thanx.
Hey Peakcelln, try to clean each and every part with +90% isopropyl alcohol. Then if it doesn’t work, you might have to replace some parts. Also, follow this teardown guide for information on how to remove the parts, and what to clean. If it still doesn’t work after replacing the LCD numerous times as well as cleaning every part, then you might have to replace the logic board. -Let me know how it goes.
