The display was broken and went totally black after one hour. During the period it was still visible, I tried to plug the phone into my Mac in order to download the files, but, unfortunately, only one cm of the digitizer was still active, in the upper part. I couldn't switch from charging mode to file transfer, because it was lower. Then, before I had the chance to try anything else, the phone just reseted. I have a pattern lock and the Android won't start without entering, so now it's forever stuck on waiting this input. The screen is now fully black and the only way to try to start the Android is to blindly try to draw the pattern with a mouse connected through an OTG cable and I can't even know it's working. The phone vibrates when I try this, makes screen captures in I press power and volume down, but that's the only input I have. There's no USB debugging, so adb don't work.
Pretty much, the only idea I have is to replace the screen, but I don't want to invest too much in this, since I have a new phone anyway. I just need to recover some recordings from the phone. Do you think it's a good idea to try to buy a cheap Chinese screen or a functional digitizer with broken glass in order to access the phone?
Or maybe there is another solution I didn't think about?
You are gonna need the LCD touch screen digitizer and mid frame assembly. You'll end up spending around 150 bucks.

Unless you have a heat plate and are talented enough to change just the screen. If you think you can only change the screen then it would save you a lot of money. For that you would need UV glue the glass screen and a heat plate. There is 1 you tube video of a guy doing this, there is no talking in the video but you'll get the idea of what you will need. You can get a screen only + UV glue and a few sledgers for about 15 bucks. The heat plate more expensive, way more expensive. I would just buy a new digitizer mid frame assembly if it was me. Its very easy to change. Hope this helps

Hi, i think i have problem with my screen, it's not work anymore, so I decided to reflash device with official Rom. But it didn't work.
Moreover before windows system start for the first time ir requires to tap on screen to boot. So now I cannot use my TytnII at all.
Is it any options to boot it without tapping on screen?
Or just to flash with other ROM, but HARdspl is not installed so a bit afraid to brick my phone. please help

install hardspl (same procedure as flashing) and then install rom of your choise if it dosn't work have you done any of the following
dropped it in water
gone in the washing machine
etc.... stuff like that
why don't you get a new digitizer??? it's $10 for kaiser?? i've been changing them like underwear...every half a year.
what is it, what's asking you to click on screen? if it's just a welcome screen, put welcome.not file in root.

hehe, i live in Lithuania, so price with shipping will be around 25$. I think this isn't very cheap. Finally got screen working, but after 30min of using again no respond to tapping, then again working fine, and after that again no. it's annoying. I think it's problem with digitizer? I haven't it dropped to water, it almost brand new

thats good you got it working
hope the problem doesn't happen again
if we assume the problem is harware, it would most likely by at one of two spots.
place, where the ribbon cable is soldered to lcd
or place where two piecies of digitiizer are connnected to each other.
might help if you check on the ribbon and glue a plastic tape all around the edge of digitizer, making it press little bit more on it
well, if that's hw probllem. but first you shoud try different rom. you can reflash without digitizer working. and check for pocket controller or similar if you want you can control pda from pc with it. there are two free and Pocket contr is trial.
if you just want to bypass the "tap here to use your device" message on the first boot up, search for "welcome.not".
create a blank file named "welcome.not" and place it in the root of your sd card and then power on the device for first boot up.
make sure it is a blank file. make sure it is named EXACTLY "welcome.not". if you are doing this with your windows pc, make sure you have turned off "hide file extensions of known file types". otherwise, the file might actually be named "welcome.not.txt" but might show as "welcome.not" on your pc.
search about it for more information.
hi, have tried differnt rom, but problem still persist. screen is not working, but sometimes it starts working very well. but most of the time it not respond. when backlight goes out and touch screen it starts to light but can't touch any options on. So what can be the problem, only digitezer or whole screen?
it was more probable it would be hw. but we need to eliminate all possibilities and reflash was easiest.
Still there is more things which could be the problem.
And there is no way to tell for sure what is it.
Did you say the pda is new? or digitizer?
And then you said when backlight goes off, digitizer will stop working, but still reacting on touch (to light the backlight) Is this right?
When will it stop / start working? Does it change if you press on body - case?
Does it change if you slide keyboard out or in?
There would be a short test each time pda/screen is powered, if digitizer fails in this test, it would be ignored till next test pass. Could this be your case?
digitizer could be broken on corner, or has bad contact inside
- You can test it, if you'll solder test wires on it and measure resistance, which should be around 500 ohms without touch and going down on each touch, can't go higher! test for both H & V
but the same reaction could be if ribbon cable connecting two parts of kaiser is broken (or connector on mobo side)
but if it's new it shouldn't.
and at last there could be problem on mobo. inside the controller chip or on it's connection, soldering. But not very probable.
It definitely looks like bad connection somewhere. You need to find out where, so you'll not buy digitizer if it's good or ribbon cable.
Put plastic tape around digitizer inside, as I wrote before, inspect ribbon cable and digitizer and it's connections. Try to locate event when it goes wrong.
If you'll not open it and check on these things, then maybe get a new part which will show bad, then I don't see how more we could help you.
You can use it without touch screen somehow or get a new phone.
Digitizer is US$8 with shipping to Lithuania. That's really cheap, even for us from central european countries.

and ribbon cable have fair price too,

papo very informative
All i want to add is that it's easier to replace the whole screen with a digitizer already on as the digitizer is very hard to remove since glued to the glass more than likely will get wrecked and not able to replace new, whereas full kit wont cost a lot more and will be less stress just 4 screws on the back plate of Tilt "where sim door is".
Well, it is not new, i've bought it from one girl, but it's like brand new, no scratching at all, very good condition.
also, yesterday i checked all the connection inside it, but the problem persisted.
I think I have understood what kind off problem it is...when remove sim card it stars to work perfectly. When insert sim, it work some time very well. Then again screen start not to respond, any ideas?

mm, I know some pretty good spells, but you need a magic wand to make them work. If you don't have any you need to:
tape the screen as I wrote before (half millimeter tape),
if no help, hardwire analog multimeter on digitizer and test it properly (while pda off and open) as I wrote before
tape bended paper across connector on mobo.
OR just get a new digitizer straight away. it's $8 and pretty good chance that it's the issue. it's maybe 50% chance but what I mean is:
You have $200 phone (now on market) let's assign it 200 points
It's working on 20% with digitizer broken, now you have 40 points
digitizer 8 points to add. With 50% chance to fix = 16 points to add
result: by adding 16 points you gain 160 (200 - 40) that's 10x gain = good risk
WTF with my screen? post photos. on the first my screen, on the second lcd screens which are beiing sold on ebay.
I decided to buy new digitizer, but when looked at my screen, it realized have completely different layout where digitizer is connecting to screen. Am i right? Is the digitizers which are sold on ebay will suit my screen?
that's fine. they all work. They are not oem but works well. Maybe not so scratch resistive.
You may get the digitizer solo, but they will not include a special double side tape which goes around and is holding it together. You can make that tape, but it's pain as stylez said. A lot of cleaning the used old one, then cutting small strips of ds-tape. and you need to put a paper or something in between two layers of tape as you need a little space in between. And then soldering that ribbon. Better just get whole assembly.
==
I see you tried that tape, before you buy it, try the last thing. The place where digitizer is soldered to lcd modul.
On that piece you sent photo of, you need to open back cover.
check the picture:
1. peel off antistatic tape from connector, from up -> down
2. take cover off
3. there will be attachment of digitizer behind the cover, like on your second picture.
Check for good connection
AND
check if soldered pins could not be touching the back cover you took off
( i had this problem once)
put electric tape accross it a give it a try - that will isolate it from back cover & make a little pressure if bad connection

Ok, so I broke the screen on my Nexus One. These things happens. I ordered a replacement screen, and thanks to numerous online guides, I (thought I had) replaced the screen.
Now, I guess that some other parts of the phone might have become damaged, but I doubt it. The phone seems to work. The touch buttons light up. The unlock gesture gives a slight vibrate. So does the volume rocker when I (seems to) reach the top/bottom of the scale.
But the screen itself doesn't show any response. No backlight (should I be able to see that). Nothing. What could I possibly be missing, I've gone over everything three times, but can't see nothing wrong. I've checked all the connectors everywhere. Somehow I get the feeling I'm missing something obvious....
Are you sure you bought an amoled screen replacement and not the slcd screen? That would cause such an issue.
Or maybe he needs an SLCD screen and not amoled..
I was going to ask if your wifi and bluetooth still work but i suppose you cant really test that yet...
I replaced my digitizer last week and now the phone works fine apart from the Wifi, Bluetooth and the charging pins for the dock at the bottom. LAME!
Maybe two Months ago I replace the full Housing on my phone is no easy task but not too difficult either. Check if you didn't ripped any of the flex cables and if the cables are connected properly. I have a long history of replacing housings and my best advice is to do again make sure you have time.
Exactly the same issue. Did you find a solutions?
I too had a broken screen. So, I ordered one from ebay and replaced it.
Now, it screen does not turn on though the icons at the bottom of screen switch-on.
I can here the sound when volume rocker is pressed.
Also, I believe that the touch is also working as I can hear the unlock sound when I swipe my finger across the screen.
Did you find a solution to the problem? Did I make some mistake or the screen is faulty?

Just months after the Nexus One was released, Google announced that the AMOLED Company "Brightstar" fell short of displays and was unable to produce more displays for HTC, so they decided to move to Sony to make the displays, To determine whether a phone has the AMOLED or SLCD display, The internal sticker on the back side of the screen assembly can be examined; part number 60H00443-03P indicates SLCD and part number 60H00287-00P indicates AMOLED, and as i mentioned, the AMOLED screens are gone so finding a replacement for that model would be merely impossible. I was looking around and thought that i may of found a fix to this, see, the HBOOTs on the devices are both the same except the top code of the screen that determines the screen type, if you were to flash the SLCD HBOOT, you might be able to retrieve a working screen, well its probably worth the gamble anyway since you probably are not going to find a replacement in a while.
EDIT: And after moments of posting, i found a AMOLED screen seller that will ship to Europe! http://www.ebay.co.uk/itm/LCD-Scree...K_Replacement_Parts_Tools&hash=item4d06825672
Dude, I dropped my n1 and shattered the screen almost 2 years ago. Bought a replacement screen and tried to replace out on my own. Needless to say, it didn't go so well, my n1 was is a paperweight. Good luck man! I miss my working n1...

My Droid's touch screen isn't working in the center vertically all the way down. I can still use the 'edges' of the screen. I need to use the middle of the screen for a few things (not transfering stuff over). Is there any way I can 'project' my Droids screen to my computer and click/touch in it to use it?
Thanks in advance for all help. It's appreciated
~mfungah
Edit: This is the original Motorola Droid.
I have the same problem on the right side of my milestone :S
I had the same problem, but from the back arrow upwards, specially when the phone got hot. As my phone was still on the warranty period, I flashed it back to stock and updated it to the official 2.2., took it to an Orange shop and got it back after almost a month: they basically changed the whole top part of the phone (I got a brand new screen )
Repair problem
I had a same failure. The touch panel was bad. I ordered one from eBay. It also came as well put it. It works well. Only so much wrong with me that for some reason the phone stacked in landscape mode, I can't change to portrait mode. What is wrong? I put together something wrong? I do not think so. Everything else goes. (or so it seems)
This has to do with the digitizer (the glass you touch over the top of the LCD you see) being defective or unsealed. This is due to environmental moisture finding its way into the phone and f**king with the electrictal signals sent by touching the screen. There is a 'phantom touch' issue that seems to happen before or during the vertical unresponsiveness, and that can usually be temporarily remedied by firmly pushing your screen downwards (your phone may restart) and taking a blowdryer to your phone until it's just hot enough to be uncomfortable to hold (and no longer take it into the bathroom while you shower). One way or another, you're going to have to replace your digitizer eventually.
Sent from my Droid using XDA App
I had the same problem months ago but it's now fixed.
STEPS:
1. Digitizer I bought from this guy:
http://cgi.ebay.ph/New-Touch-Screen-Digitizer-Motorola-Milestone-A853-/270780531 891?pt=UK_Replacement_Parts_Tools&hash=item3f0bc704b3#ht_2811wt_850
2. Dissasembly Videos (I advice you to watch them repeatedly before dissasembly):
http://www.youtube.com/watch?v=6d7ETMfgq2s
http://www.youtube.com/watch?v=dE81IaQHEHc
3. Phillips screw driver( for dealing with hard screws around the screen): Because I don't want you to use the low quality screw driver supplied with the digitizer.
4. Double sided tape: I got mine from a hardware shop for only P19. Buy a the more expensive tape(P100+) but look for a very thin one! You will use the cheap weak tape to stick some internal parts and use the Hard tape to stick the external casing. EDIT: I just used the cheap one for everything and it's strong enough.
5. PATIENCE: Don't be in a hurry. I even paused from time to time to get a better idea about what to do next. Get the feel of being a perfectionist (that same additude when I applied a screen protector )
That's the guide from me who haven't dissasembled a phone in my entire life but my milestone. So if something bad and technical that happens along the way then my knowledge can't help.. sorry.
Good luck bro!!
Hey guys.
Lately, my screen has being going insane. Switching between panels, clicking on stuff, lowering the notification bar all on it's own while not responding to my touch input at all!
Weird thing is it happens a couple of seconds after I turn on my screen. So for a few seconds it's fine.
Is there a way to fix that? Maybe the digitizer has either gone kaput or is just dirty?
The digitizer is either broken or there's too much moisture inside.
This topic has been discussed hundreds of times already - look it up please.
Same thing happened to mine... I jus changed the digitizer... I but broke my phone in the process

Digitizer Problem
Yeah, you just have to change the digitizer. This happened to me twice on the milestone. You could send it for repair, and i do not think it would cost much if its only the digitizer.
Do I need to take the whole phone apart to get the digitizer or is there a way to unscrew the screen directly?
The entire phone must be disassembled to reach the digitizer. The only problem is that sometimes it's not the digitizer that's faulty, but the flex cable, that becomes used in time. So, I suggest you to open it and see if there are any signs of degradation (it's a black ribbon that holds the sensors and the phone calls speaker). If there are, I suggest you to replace that, and not the digitizer itself.

Hi
I tried to replace my battery and after assemble it back i only get a black display when turning my m7 on.
I broke this little plastic thing from the display cable off (look in attachment)
Is this thing essential for a working display? (i thought i can fix it with a drop of glue)
Should the display work when the backcover is off the device? Because there are some connectors on the backcover....
cheers

Shouldn't have done that, I think you accidentally broke something. I'd send it to a HTC service center. But that's gonna cost you probably.
nah, official repair isn't worth it. The phone is more than 2 years old...
and yes i think i broke something... thats why im asking
You're gonna have to be good with a solder and a couple of tiny wires if you want to revive your phone.

You definitively need this clip to be intact so the flex cable sits firmly in place otherwise you'll have bad contact between the cable and the pins.
If you don't want to send to HTC for repair you'll need at least to send it to your local electronic repair shop so someone skilled with the proper soldering tool (not the standard iron you have at home) can replace the connector. BTW some of these clips must be lifted from the cable side and some other from the opposite side of the cable, so next time use tweezers and apply very light force on each side you'll find from what side it must be lifted.
LCD should work fine with the back cover removed, afaik. Connectors in the back cover are often for antennas but I wouldn't recommend to run the phone with antennas disconnected to avoid damaging the radio chips (reflected power).
If you are from the US, you can easily find this connector on ebay for about 10$. I'm sure it won't be that much expensive to repair if you bring the new connector and the phone already disassembled to your local repair shop.
Btw are you sure its only the LCD? When trying to boot the phone can you here the HTC theme or does it vibrate? Recognized by your computer when connected with usb?
thx for your response
I found an replacement part on ebay but first i have to look for someone who can solder this for me.
When i try to turn it on it only vibrates without a htc theme sound and there is no display reaction.
The other thing i mentioned is that the phone gets very hot in the middle (should be the cpu) where i dont know if it should get that hot.
I have to try the pc connetion again and let you know asap.

I'm not really worried about the absence of HTC sound when booting, if your phone is on silent / vibration mode, it will only vibrate when booting. If your computer does detect it once booted, then I guess the broken connector clip is the problem.
---------- Post added at 09:49 AM ---------- Previous post was at 09:27 AM ----------
Here is a video about the connector replacement, it doesn't look that hard to replace but wouldn't recommend to do it yourself if you never soldered electronics before. Soldering isn't that hard but you need some practices and knowledge to make good joints. I don't think your phone motherboard is a good candidate to practices yourself if you never did it before. You'll also need a really tiny tip for your iron, probably a type "L", 50/50 solder + some flux. Flux must be cleaned after use to avoid corrosion. The most difficult when soldering on motherboard, imo, is to find the right temperature. If your iron is to hot, you'll damage your connector. If its not hot enough, solder will take more time to liquefy and some heat will be absorbed by surrounding components which can cause irreversible damage.
Easy fix mate
You don't need to replace the connector, I've done this before, it is just the connector clip that has come off and it goes back on reasonably easily.
You will need a good magnifier.
You will need a good light source.
The phone held securely on its side with the socket pointing up.
Some masking tape on the loose part because it WILL go "ping" into the distance if you don't and you will not find it.
Look at the other connectors to see the proper orientation for the part, mark it with a permanent marker on top and at one end.
The insertion looks difficult, it isn't too bad, keep the part nice and straight and the motion is kind of like clicking it down on the ribbon.
Forget replacing the connector, that is 100 times harder.
If you do lose the loose part I have one or two laying around.
Good luck.
