Why is my screen white after I replaced the lcd and digitizer?

I cracked my screen and ordered a replacement. Upon receiving my the new LCD and digitizer I carefully installed them and reassembled the iPod. Now, when I try to turn it on the screen is white. I tried to do a reset by holding the home button and screen lock button for 30 to 40 seconds, but that did not help. Any ideas of what I may have done wrong? Could it be a faulty part?

Thanks so much.

I just tried to fix an ipod touch 4g with cracked glass. After a careful teardown and re-assemble I encoutered the same issue. I even tried connecting the old screen with the cracked glass but found the same white screen haunting me. I am going to try recboot but I am now wondering what to recommend to the customer I have. Any progress Travis?

Hey bill. I did eventually get mine to work but I ended up getting another new lcd from the same guy who sold me the first one. When I plugged in the second one it immediately showed up. If your having the same issue then out could possibly be a faulty lcd. I was also told the lcd and digitizer had to be fuzed together but they were incorrect cause mine works just fine in two separate pieces. I hope this helps! -travis

But if i put the old screen in, all works fine. But with the new I got this. I already reset the ipod etc but nothing seems to help.

What do I need to do?

Kind regards

Recently, I bought iPod Touch 4 LCD Assembly from China after replacing it, my screen went to white only. Eventually, I realized that Digitizer connector is different from original one. The original one has wider plastic block in the middle of connector than faulty one from China. Do you think that the different connector makes white screen problem?

Travis Mo, it is always possible that it is a defective product, but first what I would do is to disassemble again and triple check the connections and to make sure that everything is seated properly and that all cable and connections are clean and straight.

it looks like everything is clean but its hard to tell if im lining up the part where the ribbon cables connect to the motherboard. i assume its got a good connection cause it clicks it and seems like its how it should be but still no luck...

Hello, all! My name is Chris. I want to thank everybody that contributed to the answer on this forum regarding holding down the home, power, and up volume buttons. I had a white screen and after a few tries of holding down the three buttons, I started praising God when I saw that Apple logo!

Thanks again, guys!

this is a common problem, look for a program called recboot stick the ipod into recovery mode and wait a min, then connect to itunes, then quit itunes again, run recboot again and kick it out of recovery mode this should sort it out, if not then it is possibly a fault caused by static which can sometimes resolve by running the battery completely flat and leaving alone for a day or so then put a little charge in it again!

so i tried using recboot and it told me to download usblibO.dll and some other file so i did but after following a tutorial on how to do it i still couldnt get my screen to show anything but black or white. i can tell its connected to itunes cause my computer notifies me that its connected but i still cant figure it out. thanks for the help

Although i have a 3GS, i had a similar problem after replacing the glass. However i had fixed my screen by pushing down on the connector, it apparently wasn't in all the way so it just showed the white screen. Try it out and tell me how that goes.

it is the connection I hold mine down and it works and I le it go I feel it move and it goes white. the LCd connector is a pain in the rear end to stay down while putting the screen in place

Update

it is the connector when I hold it down it works but when I let go it moves and the screen fades to white. so the connection is incomplete. Th connector is a pain to keep down in the replacement.

I have just managed to replace digitizer/lcd. First the result was white screen. Then I changed back to the old screen but now that was white too. Then I tried to reset ipod like described holding home, vol. Up and then power button. Hold all three buttons until the screen turns on and show the apple. After several tries it worked and I replaced the old screen with the new again and it worked. Good luck.

In most cases its a loose connection or you need to reset the device.

On the other hand I've actually seen screens go white that are defective. To double check, I hang on to a couple of old cracked screens just to connect up to rule out a bad replacement part.

Be careful though, pulling up that logic board over and over to re-connect the (thin cable) to the bottom of the board can be trouble - logic boards have a tendency to snag the power/volume flex cable and tear it, which means soldering and a lot of hassle. I smooth down the power cable with a pry tool and stick on a piece of Kapton tape (after a few "costly" mishaps) before pulling up the logic board.

Last, don't use your finger to snap down the cable onto the board -- use a pry tool - gently, because too much force can break off the connector on the logic board and your into big mess.

I've ordered from wholesaler's that get their products from China. A few months back I got a batch of replacement screens and none would work. The replacements, which I received, had 4 rows of connectors on the thin cable vs 2 rows that is standard on the stock screen that came on the iPod.

If you look at the one in the top photo, the one with 4 columns of pins, I could never get those to work.

However, the bottom photo, is a replacement that matches the connector that comes built in from the factory. They have all worked fine.

While holding the home button down and volume up button, push and hold the power off button and hold that until you see the apple sign.

Hi,

I have similar prob. Few weeks ago I have replaced LCD assembly to one customer, and it worked fine. After 5 days he brought it back to me because it was showing just a white screen. I have opened and checked LCD connection tried it again, and for a few seconds it came back to live, but then again back to white screen. I fitted another brand new LCD unit and it worked just fine, but today, after 4 days, i have received a call from him saying that again he is got just white screen. Did anyone had similar issue with these LCD units, and maybe someone can give me some advice. Thanks.

Hi everyone,

Just have sorted problem. The solution was one more brand new screen. So it took me three screens to sort this out...

Anyway I do think, that you must be extra careful when replacing these screens, as these flex cables are very fragile, and it is very easy to damage them.

if it is a white screen then let your ipod die and then plug it in let it charge and it should work just fine.

sometimes for a white screen i find disconnecting the battery and connecting it again is a fix, not for the faint hearted or inexperienced

The white screen problem is easily fixable, since it's a static crash when you deal with the LCD, it's just power button + home button for 7-10 seconds. My problem is getting the Digitizer to work once the LCD is working fine. Having issues with the digitizer connecter at this point, I'll post an update as to what it is later..

I had the same problem. I replaced the screen and after I put everything back together I got a white screen. Hard reset did not help.

The connectors on my replacement screen didn't have the black rubber protectors on them that all the other connectors in the phone have. So I just put a few layers (2-4 layers should do the trick) of electric tape on the screen connectors so the shield that goes on top of them would push them down. I turned on the phone and was greeted by a lovely apple logo right away.

Hope this helps.

I couldn't get it fixed yet. Same problem with the white screen after replacement. At this point I still believe is the screen itself faulty, but I'm going to give another try tomorrow. I have to leave the battery to discharge completely because after I tried to reset it with the home button, power button and volume up it went back completely and didn't want to come back at all, not even to the annoying white screen. I've also tried the trick with the battery to reset it, but no luck at all. I've seen screens who work from the first try without any pampering and screens that don't work at all no matter what. I still believe it's a faulty screen I've bought on ebay.

This is really good stuff I have seen the issue with the different connectors and that its self is a big problem, send it back I found this seller on ebay and never had one problem with the white screen, black screen again, I own my own repair shop and been doing this for quit some time now and had this problem many times, run the battery out recharge, always on the connector that is on the underside use a bit of the 2mm double side tape after it is seated, when you replace the board back in it comes loose, that is why when you first open it up it has the copper heat sink tape on it not only for the heat but to keep it sucurely in place, I also use the amber heat shield tape to hold the top cable down securely because when u move it just a bit putting it back in it can wiggle loose, thus the white screen. The ebay seller I use is

Hudson_River_Goods (10360) $24.45 in the 3 years of dealing with them never a problem with the white screen, make sure its off before you start, be care with everything, and dont heat to much before or after, heat will also cause these cables to be unstable at the screen side do to they are not soldered to they are heat pasted soldered thus heat will loosen them. The guy above with the pic showing the difference in the connector is right, one is for the begining ipod in the that gen and the other is for the later in that gen, if you go cheap you get white screen use the seller I told you about and you will be just fine, good Luck.

Thank you and Good Luck

I purchased a new screen from eBay to replace a cracked screen on a iPod Touch 4th Gen. After replacing the screen I got a white blank screen. I did a hard reset and the screen showed the home screen. So I continued on to secure the screen to the iPod but the ribbon cable became pinched between the metal. The screen became white again and I haven't been able to correct this. The iPod then wouldn't even turn on or show any sign of life. I had to short the battery terminal and this allowed it to turn on again.

I tried removing the screen and reinstalling it again from scratch to no avail. I tried a hard reset again, nothing. I tried connecting the iPod to iTunes to get it into DFU mode numerous times and it just wouldn't work. Finally after, trying and trying I was able to get it into DFU mode and iTunes recognized it and restored it to factory settings.

Once the iPod was fully restored I was hoping this May fix the white screen but I was wrong. I am able to see the home screen through iTunes and the iPod is responding to syncing, but just got the darn white screen still.

Am I looking at needing to get a new screen again?

Update

Update: received the replacement screen in the mail and went ahead and installed it. Everything is good to go now. The first screen I received was defective.

Tried yet again to remove the display assembly and start from scratch. This time around I was able to get the home screen on the iPod but just for about 2 seconds then it would fade to the white blank screen. Also noticed that the LCD would show horizontal lines throughout the display.

Anybody have some input on this?

The lcd connector on the ipod itself could be broken.If so it is not too smart to try to solder it.Please tell me how it goes.More than likely it was just the faulty screen.If you get it soon,you should check if it works first,make sure it is actually good.Therefore if it is bad,you will know you didn't do anything.

First recheck the connection.I had it happen too.It is most likely because the lcd connector in either on bad or is ripped.When you move it it causes it to have distortion.I tried before but the screen I got sucked.I broke the speaker wires and the whole thing was destroyed.I think some screens are bad.Read reviews on them first,then buy.

I really had the problem a few months ago.I moved the lcd cable ( the thick one on the top next to FaceTime camera) try moving that if the soft reset does not work. The soft reset is holding the home button and power button down together for 10 seconds roughly.Let me know and I will gladly help you out.Good luck.

Note ( be careful.If it is an ipod you like you should send it somewhere cheap to be fixed otherwise it could be destroyed.) luck

Helpful tip.....If you heat the adhesive up after applying it,it will make it kind of gooey therefore making a good connection.NOTE..Do not hold the heat dryer over it too long,especially in one place. You could damage the components.

by

You also want to shut the ipod off all the way.If the digitizer is connected well,then you can just swipe where it would be because the color does not cause the touch to be bad.

Well guys, reading your problems and your solutions has been very instructive.

More or less same symptoms and same solutions, and when not able to get out of the white

screen,replacing the LCD/DIGITIZER assembly does the trick.My assumption is that in many cases when Resetting or factory Restoring doesn't solve the white screen problem,is because the connector that connects under the main board is not inserted completely,perhaps bent too sharp etc.etc. but anyway it is a faulty connection,therefore, replacing the LCD assembly solves the problem. Not necessarily because the previous Assembly was defective,but because this time around the male and female connectors were firmly mated.

I have a darn problem myself with my daughter's iPod touch 4th gen. I replaced the screen assembly last week,it went perfect,after 2-3 days it gave me a white screen.Tried hard reset,factory restore,nothing to do.The screen not glued to the frame yet.When resetting the iPod I had the Apple logo appear for 1-2 seconds and then back to white screen.I was ready to replace the LCD assembly when suddenly the word IPOD replaced the white screen,it was the lock screen background picture!

What happened was that without knowing, I was applying pressure on the top left side of the screen.I will let you know how I solve the issue.I have no time now.

Thanks for reading.
