Digitizer(Touch screen), Not responding after Tear down.
Hello,
I am experienced in almost all Mac hardware,but i am stumped w/ this issue. Any Help would be great!(iPad 64gb Wifi)
I tore down my iPad to replace a peeling digitizer. Upon reassembly, The iPad was working O.K., but the digitizer was locking up and responding very poorly. I decided it must need replaced and ordered a new digitizer through ebay. Now after replacing the digitizer, the touch screen will not respond...
The home button works fine, as well as power/volume/lo
UPDATE:
It has been nearly a year now, So I figured it can't hurt anything to try a new digitizer. My Ipad still powers on, resets, inverts, connects to itunes, chargers etc. etc. etc. I have thought about this thoroughly and there is no other logical answer besides the digitizer I received is defective.
When the iphone 4 was new alot of the replacement screens were garbage, and I think it ws the same with the iPads. I originally believed I had damaged the logic board when the retaining clips on the logic board broke off, but after speaking to an electrical engineer, He doesn't believe this makes since. He fixed his broken retaining clips using a thin strip of mylar tape under the tab. I ordered a roll of mylar tape and the entire display assembly which includes the display, midboard, digitzer, clips, etc and a roll of mylar tape for 60$, I will update as soon as I receive the shipment.
Update 2:
Replaced the digitizer again, and no change. As a conclusion, this board is fried, and my iPad is a useless paperweight... I would not recommend buying a logic board for one of these, it's just to much money compared to an ipad 2 16gb. It is really unfortunate, Everything works software and hardware wise, but the screen just doesn't respond to touch. You may be able to salvage some of your loses selling it for parts on ebay.

What I did personally, which seemed to be a good "Permanent fix" was i purchased a roll of 3/4" mylar tape off amazon for about $8.I cut a thin strip the same size as the ends of the digitizer ribbon cable, then I attached it to the top (Opposite side of the gold on the ribbon cable). What this did was create a spacer between the ribbon cable and the socket it fits into, making it harder for the ribbon cable itself to come loose.
If this doesn't make sense let me know and I can email you some pictures!
Wxcarne89: Can you please post some pictures of the Mylar tape repair. Would really appreciate it. Thanks
"He fixed his broken retaining clips using a thin strip of mylar tape under the tab". Wxcarne89, What do you mean by this statement. I replaced 3 screens and took a few apart and had no problems. The digitizers I got had the clips allready screwed on. The ones I took apart for minor fixes I had to get new clips, as most clips break when you use the flat opening tool.
Hello, I am referring to the poorly designed retaining flaps located on the logic board itself (that hold the digitizer ribbon cable in place). These retaining flaps are "supposedly" designed to only be used a few times, similar to how the pentalobe screws on the iP4 are meant to strip easily. To anyone who has had these flaps break off, I can vouch for using mylar tape to hold the ribbon cable in place. The digitizer clips, for the frame, almost always need replaced. i finally figured out how to get the digitizers off without breaking the clips. The first few times I removed a digitizer, the clips were a total loss.
O.K. now I understand. I somehow missed that you were referring about the retaining flaps for the dig. cable. It's lots of fun fixing ipads, ipods and iphones. My biggest problem lately is getting good parts on ebay. It's all knock off chinese junk. Apple is the worst problem of all. They provide no support whatsoever. No repair info, no parts info, no nothing. If it's out of warranty they just want you to buy a new product. Thank god we have IFIXIT. They are the greatest.

I just wanted to report back to all the doubters and the hopers alike: The mylar tape fix worked!!
I used the method described by previous posters: get some mylar or kapton tape off the internet. I bought from amazon. I paid about $10 shipped. I could have gotten it cheaper, but I wanted it as fast as possible. Make sure you get the one that specifies that it is an insulator because otherwise you may end up shorting together some of the pins on the ribbon cable. This take will act as a spacer, pushing the contacts on the cable against the pins on the logic board. All I did was attach a tiny piece of tape on the back side (side with no contacts) of the cable. I covered the entire back including the little dotted white line. That line has to be almost completely invisible (obscured by the connector on the logic board) when the cable is fully inserted.
TEST IT BEFORE YOU CLOSE IT BACK UP!
If it's not working, you either didn't put on enough tape (you can see on mine it took two tries), or you need to push the cable in farther to the connector. Be gentle! And good luck! don't give up, and fix it yourself! I ended up with a fully functional $40 ipad!
What is the thickness of the mylar tape in thousandths? You could probably use scotch tape or packaging tape. I never had a problem with countless opening and closing of these flaps but will keep this in mind if I ever do.
The tape worked for me too! Im using Scotch tape. Is there a difference between mylar and scotch tape? We gotta get the word out!! iPad 2 here
Yeah, one slight major difference. Ever manage to have scotch tape stick to you by the back side (non sticky side)? that's cause it conducts static electricity, something you don't want in the internals of any electronic, especially not an ipad. Just cause it's working now, does not mean it won't eventually short some of the pins on that piece or elsewhere. The reason for mylar is that it is industry know insulator, and in fact you can find it in some other places in the ipad used originally by apple. (holding the light sensor onto the mid-board). Good luck!

This is probably a dumb question, but why do you need mylar tape? Why can't you use say, masking tape..is it too thick? Do you need something for conduction? Or is it also due to the thickness?
Do i just put the tape on top of the digitizer ribbon so it is thicker, and presses the cable to the board? If I put the tape on wrong, will I be able to peel it off without hurting anything? It looks simple, from Tonys' picture...is that really all there is too it?
Sorry, I am just trying to understand the fix... I had to re-read this page a few times to "get it"...!
i have the exact same problem as you.......someo

Hello,(Ivannahu
Wxcarne89,
I am having the same problem as well. I am going to contact the seller to try to get a replacement.
Tony,
Yep, I thought it was kind of a long shot too. I found a previous post related ti this on here by a guy on here who is an engineer and messaged him to see if I was understanding him correctly. Long story short, I have now recommended this fix to a few people who have used it successfully. The guys I've spoke to have recommended using mylar, so thats what I have been using. I think one of the big reasons it's recommended is because it is very thin. Mylar is expensive though, I don't think it could possibly hurt to use the thinnest non conductive tape you have laying around. I really wish I could fix my 64gb ipad, but I am just kind of over it now. Cost wise it just doesn't make sense. I'm thinking about grabbing a samsung galaxy 2 7.0 this week, so I don't have to carry my 15" pro in it's pelican case to class everyday. Good Luck! Hope this works for you!
Wxcarne89,
Has anyone tried those service that solder a new "receptacle" onto the logic board. id love to fix this for less than $150!
