The reason why that little diode is important is that with the 4R7 coil it makes a boost converter that steps up voltage to 16.5 volts for the series string of LEDs and then another component regulates the current to provide brightness adjustment. I have seen this on laptops with b0rked CCFL/LEDs before and once actually toyed with the idea of getting an EL backlighting panel for an old 22' screen until the price list came up- $200 for a panel, although EL wire of the high brightness type arranged in line with the horizontal axis will work for those extra spooky projects :-) (about 10.6 metres for the screen I have) The power disconnect method works but you have to be very careful not to use anything metallic. Turn it off and finish the re-assembly and glueing.Īlso had this (once!) when changing a front glass. Turn on the device and test the LCD and everything else, Connect the LCD, and digitizer but don't glue it back in, Do the repair/change the digitizer or whatever., Try the LCD and everything else before disassembly to make sure nothing was defective to start with! Turns out the home button was not seated well enough (especially that the digitizer was not tightly back in place). JUST MAKE SURE YOU DON'T SHORT ANYTHING ELSE AT THE SAME TIME!! This time the restart was successful, and the LCD came back to life. So I shorted the 2 golden pins of the Home Button while pressing the ON/OFF Button for 10 seconds. The iPad wouldn't restart/turn off (I could still hear the charging sound when I plug it in). So I tried rebooting the iPad by pressing HOME BUTTON + ON/OFF BUTTON at the same time for 10-15 seconds, but nothing happened.

I tested the LCD on a another iPad, and there it worked. I plugged the iPad to the charger and heard the charging sound, so the iPad was working fine. So I disconnected the LCD and digitizer, and cleaned the old adhesive using rubbing alcohol.īefore gluing the digitizer back, I tested the iPad and found that the LCD remained black. You may want to make a Genius appointment.I changed the broken digitizer of an iPad 2, and used what turned out to be a poor kind of adhesive to glue it back.ġ0 days later the digitizer became loose and I needed to re-glue it.
