iphone 3gs "no backlight" repair video MY EBAY Store http://stores.ebay.com/Tinner105?_trksid=p4340.l2563 My Email is Tinner105@verizon.net Here's some info on where t start looking for the no backlight cause. 1st make sure it not the lcd its self. there's a row of lights along the top of the LCD they can be bad and the lcd display still works but yiou cant see it because theres" no backlight" Icf you have access to another 3gs try their LCD assy in yours, if it works..... its your lcd. If not try your LCD assy in theirs if it works theirs a problem on the board somewhere. if it dont well you can figure where the problem lies. If you think the iphone got wet. YOU MUST OPEN IT UP PERIOD, Rice and such are a temp solution. There's corrosion working away on the inside and you have to stop it. Here's what you need to do. Completely disassemble the phone. Remove the main board Remove the metal covers and clean up the main board. Use either an ultrasonic jewelry cleaner, or just a toothbrush and alcohol. Use a magnifying glass to see where there is corrosion. Pay attention to the LCD connector area, pins should be nice and shinny. Check around the coil area, and the components next to it. Like the 109b ic, it's the small black square next to the coil. There's three solder points on both sides. The side closest to the outside gets corrosion between them and that can cause the backlight to not work. Just because the water indicators are still white means nothing. Look on the backside of the board too. Water gets between the battery and the board, so clean the underside too. Try cleaning it real good first. If no backlight, check the LCD. Try your LCD assy. in another 3gs and vise versa. It could just be the LCD. But clean the board no matter what. If you need any other help contact me.
