I'm repairing a Treo 680 for someone, and when I was replacing the LCD screen, the latch that holds the cable in place broke off. Now, the cable doesn't stay in, causing the whole thing not to turn on. I've tried taping it in place, that didn't work, I've tried sticking the latch back in, and that didn't work either. Is there any way to fix the latch or use something else to hold it in place?
