I have just received my new lcd display that I have recently order from ifixit last month (11/25/014)for my ipad mini, the repair went smoothly with just a few minor set back. After the installation repairs, I turn on the unit, it power up the apple logo appears, no problems whatsoever. But I notice something. Half way down in the right side of the display, there appears a four digits, numbers 4904T. Thinking that I probably forgot to remove a protective sheet from the display, remove the digitizer and check for the protective sheet, but did not find any on the display. I have also check the digitizer glass, but found nothing. Just to be sure, l turn on the ipad without the digitizer glass, and chech the lcd display, the numbers are still showing on the screen. I have also open other programs, like safari, apps, utilities, youtube and games, with the same results the numbers are still showing. Is this normal for a new lcd, if not how could I resovle this issue. Thanks.
The lcd should always have a protective sheet on it sometimes it doesn’t look like it because it’s on very smoothly. Take a thin blade and try a corner. If no luck then try some alcohol on the numbers and it should wipe off.
Is the character color for the visible serial number written in red? If so, I had the same situation and it was the protective screen cover. As ‘con’ stated all you need to do is remove the protective film. Thanks
