iPod Touch Screen Replacement

[732914TECH]

Started this thread to prevent myself from hijacking another thread, In regard to replacing the screen on a Ipod4 touch, Whenever I replace the screen and install the adhesive, and press the screen in, it does not want to stick to the adhesive and stay there, it comes out a little bit, Not a lot but enough to worry me. I know PCX has this issue, does anyone have a solution?

My guess is the mid frame is slightly damaged and/or something under the screen isn't sitting right.

Does anything under the screen move around or lift up before you put the screen on?

Check to make sure the digitizer cable is folded up properly and not under the LCD. Also check for small bits of glass sitting on the edge in the adhesive. You definitely do not want small hidden glass under the LCD itself cause when you push down it could crack the LCD.

I have done hundreds of iPhones and iPod touch 4th gens. Unless the housing is visibly bent up then screen should fit flush.

 

[PCX]

Yeah, the housing is probably bent in many cases . . . I know some times I have to rework the corners a bit just to make the glass fit.

I dont think mine have been bent, If i push it down with my fingers it sits flush, but as soon as i let go it comes out a little bit. It seems as if the adhesive is not sticking.

Lay the ipod down on it face without the screen and see if it has a bow in it. As for the top corners, there is very little for it to stick to and even out of factory there is some give.

We heat up the adhesive and the put the screen down. Then we use rubber bands to hold the screen down flush and tight for a couple hours or until the customer comes to pick it up. Very rarely is the case bent just slightly where we very sparingly drop some strong glue in away from the sides cause the last thing you want is white glue adhesive all over the outside of the iPod. If the corner is bent then yes you will have to try and carefully bend back the corners so that the screen fits down in the housing. Only twice did the customer have us replace the housing.

I hope you guys aren't close to me lol.

I was going to say somethign about you being pretty arrogant in a previous post, but then I figured it was just unintentional, but I think this is the 2nd or 3rd post that you are clearly being arrogant on purpose. I know its hard, trust me, but try not to be a . . . well, even I got to try and avoid certain words.

Anyways, thanks for the rubber band trick, that may very well be the trick that does it for us.

Also, +1 on heating up the adhesive after installing the screen. We always do this on the iPads, iPods and Macbooks and we have not had any come back yet.

Not trying to be arrogant and nothing was directed at a certain person just trying to be straightforward in the solutions I have found for the same issues you guys are having now are the issues I delt with when the iPod touch 4 first came out how ever long that was.

My first repair was a joke and I so wish I could reverse time and actually fix the iPod that I destroyed. Because of the mistakes I made on iPods when I first started I am able to now successfully replace the screen, resolder a new volume button / power button ribbon cable, resolder a new battery, and then change out the housings.

So I apologize for coming off as arrogant.

No problem, I had a rough time starting out here too . . . wont go there. Anyways, we just started doing these repairs about a month ago and have been doing pretty good, but every once in a while, those iPods kick my butt. Any other suggestions on getting them to sit completely flush? I noticed that there are little tabs on the side of the LCD, like they tuck underneith the lip of the housing . . . any thoughts?

Just an update on the iPod repairs. First I want to confirm that rjg.techs advice on using rubber bands after installation is a great trick to make sure that the iPod sticks to the adhesive and stays down. Also, as I already mentioned using a heatgun on the adhesive before install will also help to make it stick. Finally, I had a iPod screen left over from a previous repair that is in good condition but the screen does not work. I cut off the ribbon cables and I now use it to judge whether or not the glass and screen will fit properly before installing the adhesive and new screen. If it does not due to bent corners and such, then you know you need to rework the corners a bit till it fits. If it does fit correctly, then you know your ready for the install.

Another thing to keep in mind, I would make sure you are replacing the adhesive on the white area near the wifi cable. If you are using the pre-cut adhesive, it usually just goes around the edge, so adding some to that area will help the top left area stick better.

If you're following all the good advice in this thread, you should be able to get a flush fit for your screen.

Excellent advice on this thread. We've been doing iPod/iPhone/iPad repairs for the last year and a half and ran into all these problems at the start. Where do you guys go for your replacement parts? (don't worry, no in the same country as most of you, so no need to worry!).

when i was done with the repair i laid the ipod on its screen and put something on top of it for a few hours and it sit flat on the table, but when i remove it it still didnt not adhere to it. I think i dont have good enough adhesive.

Can you post a link to what you are using for adhesive?

I just did my first iPod touch screen replacement today. I was having a horrible time getting the screen to sit flush, but this will apparently be the second replacement on this ipod. It's currently sitting with about 3 boxed power supplies on top of it holding it down. We'll see what it looks like tomorrow but I'm not holding my breath

Do you guys reuse the metal bracket that makes contact with the tiny spring?
Is it actually needed, any tips on getting it to in position, what are you using as adhesive to stick it to the LCD case plastics???

I had a nightmare trying to get it in position and in the end left it off and then the screen fitted fine.

Would love to know more also about the adhesive used.

Personally I find iPods incredimally time consuming. Especially with sausage fingers!

 

[ITGroup]

Which metal bracket are you inquiring about? There are two in the iPod Touch 4th Gen. There is one that covers the rear camera and one that is attached to the glass.

I would imagine you are asking about the one attached to the glass. I find the easiest way to attach this is lay it on a small strip of double sided tape and then use a sharp box cutter to cut away the excess. Look at the guides on iFixit to see where it needs to go.

Yes, I always use the metal bracket. I clean off the old adhesive, and then attach it to the screen using Tesa 4965 adhesive. To get it in position, I hold the screen up to a bright light, then match the hole in bracket, with the sensor hole on the screen glass (holding it up to the light, makes it easier to see the hole on the glass).

Then when you put the new screen on, you slide the top end in first so that the bracket engages the frame.

Here is a link to the Tesa 4965 I use http://www.amazon.com/Tesa-Double-s...TF8&qid=1345034674&sr=8-4&keywords=tessa+tape

It was the adhesive that came with the screen kit, The thin strip that went around the whole edge of the screen. plus i added some extra with no luck.
