iPhone 3G Odd Backlight Dilemma

Hello all, if anyone here can help me, I would appreciate it.

My back light went dim a few days ago because my chrome bezel was lifting up by the power button (fixed that issue) and I had to hold the screen down just to push the power button. As I was pushing the power button, my back light went out and would not turn back on. I thought maybe it was the LCD, but then I decided to take it apart and do some investigating hoping it was something simple. I found out that my backlight still works but only when I reconnect the digitizer cables with the logic board, once I try to set the digitizer back down onto the case the light goes dim and won't light back up when I touch the screen or home button. I really hope someone can help me understand what is causing this issue please. Thank you in advance.

Sounds like your Flex Cable #1, the LCD display Flex Cable #1 is lifting up as you close the iPhone. Sounds like you have issues in that top corner regarding closure due to previous loose bezel there. The Apple #1 sticker is a cushion that normally helps keep the #1 Flex down against the Logic Board. Maybe glue or tape some Foam or Plastic (Credit Card or thinner) to the top of the Apple sticker, to help keep the #1 down.


Thank you Brad for answering, I just tried this and it did not work.


Is there any other solution to this problem?

Its possible that your LCD connector is just not as tight as it used to be. If you swap that out, the problem may go away. However, if the current LCD has never been removed, it may just be pulling the connector on the board away from its terminals, and causing the backlight to go out. Once too many times, and the coil will go bad. Try with a new LCD first if you can.
