Answer to: Th screen stays black after a digitizer replacement.Jumping the backlight filter is a bad idea guys--that will likely cause you (or your customer's) backlight coil to fail prematurely. This is especially true if you are putting a mini back together and testing your digitizer soldering job, home button etc and keep plugging/unplugging the LCD. The filter is an easy part to replace--about $5 on eBay. In fact, replacing the whole backlight coil, filter, and ic is less than $20 for parts cost and takes just a few minutes with a hot air station and a little experience. The mini does seem particularly sensitive to the sudden change in voltage that comes from unplugging the LCD. I've learned this the hard way!
Answer to: iPhone 4s has a black screen chimes constantly when plugged?Did it have water damage or drop damage? Black screen can mean the LCD connection is loose, or (this is common) something happened to the backlight track on the motherboard. There are two tiny little filters that often fail. You can make this repair if you are adept at micro soldering. The chi see very second problem is similar, either it is bad dock connector, or a failure of one of the components on the motherboard. Good luck! Jessa
