I recently replaced the digitizer screen in my Ipad2. All went well and I thought I was home free until I tried to turn on the Ipad with the on/off switch. It did not respond with any signs of life. So I plugged in the AC adapter and it came to life. Unfortunately, it still does not respond to the on/off switch, and I found the volume control buttons do not work as well. Switching the mute button on/off does switch from a speaker icon to a bell icon, but I get no other indications of volume control. In desperation, I replaced the power and volume control cable with a new one, but the problem persists. Any advice appreciated.....and no, I doubt I'll ever try this again. Thanks.
