won't power up, no light on screen
A friend brought me her Ipad3 and said she was installing IOS7 when it suddenly turned off. She tried powering it back up and resuming installation, but can get no light on the screen at all. I tried all the tricks I know to reset it, (holding down the power switch at top of tablet while also holding down the home button at bottom of the screen), all to no avail. Then I plugged in the AC adapter and let it charge overnight (there was no indication of any activity, however the unit was slightly warm, (presumably the batteries inside.) Then tried all the reset tricks again, to no avail. I tried the overnight charge again and next morning I found it "chiming" every couple of seconds or so (the sound it normally makes one time when you first plug it in to the AC. Also when I pressed the Home button, an area in the middle of the screen (about half the entire screen) lit up all white, with a fuzzy edge all around. It stayed on a few minutes, then disappeared when I pressed the on/off switch at top of case, and never came back on again. Now the screen is again totally black, no sign of light or power or any activity at all. Just the chiming when I plug in the AC adapter. I removed the screen assembly and checked all the connections at the power switch and Home button and cannot see anything that looks loose or unusual. That's as far as I have gotten. Does anyone know of any other "tips" to isolate the problem further, or do any of these symptoms sound familiar? Any advice appreciated. Thanks.
Ist dies eine gute Frage?
