Nokia Lumia 820 Digitiser - Nokia Lumia 800

Hi
I have been searching the Internet for this answer to no avail
Well, I've changed a cracked digitiser that was totally cracked and dead, I've put the new one on, however the soft keys don't work.
Now this is the question, I'm trying to figure out whether the new digitiser is faulty. I don't know what controls the 3 soft keys, its either the digitiser or are there 3 sensors on the frame.
I wonder if someone can answer this for me. If the 3 soft keys are controlled by the digitiser, then I know this is faulty.
Please help.
Thanks

Not that it helps you much, but I've got exactly the same issue with a screen bought last week.

Replacing Lcd Screen caused by wild friend

Hello,
yesterday I installed some new games on my p4350 and let a friend play with it,
unfortunally he pushed to hard with the stylus and the screen got damaged . the screen is still working but it got a dent.
now I wanna replace the screen myself, anybody can give me instructions how to do this?
Also i wanna know if the soft layer on the top(not the screen protector) and the lcd, is one thing.

Replacing digitiser on Herald as opposed to Hermes
Scuse me for butting in but I have both just bought a Herald with a broken screen AND have done a few screen replacements on Wizards, Blue Angels and Hermeses.
On this Herald I had just assumed that you could basically follow the video on YouTube which shows how to replace a screen on a Hermes? I see that the PDF file is quite complicated and is designed to show you how to take off every tiny part if it has failed. The screen replacement is far easier that this, right?
Secondly, I see that you can buy the screen separately from the 'protector' which is I assume the bit with the hole in on your unit? I have to say, I had never seen these replaced separately before: Is this something special to the Herald or can you replace this digitizer separately from the screen on other units as well? If so, how on earth do you get it off the screen please? And is there a reliable way of getting one back on? (There is no reference to this in the pdf manual but the digitizers are suddenly being sold on ebay for about five bucks)
So the question is whether this is still as difficult on the Herald as threads on the Hermes suggest?
I've opened my Herald, and to reach the screen you have to disassemble the whole thing.
It's not that difficult (albeit while following the service manual, since there are a lot of tricky areas like removing the Keyboard), you just need to have patience and not rush it.
Any way to set up device after flash with no touch screen.
The digitizer or screen is not functioning, before i take it all apart as shown anybody no of a way to bypass the touchscreen setup.
before trying to change the digitizer...
(and i know this is crazy but worked for me after replacing the cable going from the screen to the board)
install a screen protector and try again!
I had the same problem after opening my Herald, and right now the screen only works if i have a screen protector on. If not then nothing happens
digitizer replacement is actually very easy.

As I have now posted on a different thread, the digitizer replacement is actually very easy. You just slip a razor blade under the tabs and lever it off after removing that yellow tape on the back.

I agree. It was not difficult at all. I took apart and put together the phone a few times after just to develop a feel for it.
We have a tendency to get nervous about it but if you relax it becomes easier.
I have a a extra digitizer that I never used. If anyone wants it, pm me.

[Q] Galaxy s2 screen repair fail - buttons dont work now

Good Day folks, here is the long and short of it.
Galaxy s 2 fell and the screen broke
I bought a new screen
Replaced the screen BUT two big problems occured.
1. The screen appears to have less colours than my original screen
2. NONE OF THE SOFT KEYS WORK, HOME, MENU AND BACK DO NOT WORK.
Number 2. is the big problem. Does anyone have any idea how these buttons work?
Even when I press the buttons directly with my fingers with the buttons off they still do not work.
Im baffled. Please help.
I also have attached pictures of the button area
It happened to me, I removed the screen, I replaced from beginning and it worked...
Hi Collado, do the white things behind the buttons have any electronic functionality or are those just things to make it stick?
To all future readers. I found out what the problem was. Basically,
The home, back and menu keys are all connected to a single ribbon. It appears there is a tiny piece, connected via the back key. That was torn while i was ripping off the the screen and digitizer.
See the picture attached
How much did you pay for your replacement screen and where did you get it. My digitizer is broken due to a drop. My front glass is perfect but the digitizer is completey shot. How difficult was this project?
Hi Johnboy
I cant remember the price of the digitizer offhand but make a check on ebay.. that is where i got it.
Difficulty is high as you need the minature tool set to do this effectively and a gentle touch.
However, it still appears as though the screen I bought has less colours.
Sorry to jump in and unintended hijack
I also dropped my S2 and cracked the screen, and after checking around dropped it in to the Geek Squad at CPW. Who duly replaced the screen and digitizer for £80. Only problem is the screen seems less bright and if moved off the central viewing angle the screen dims, as if it wasa standard lcd and not the orginal AMOLED screen. Does anyone know if they make lesser screens or was it fitted badly.
Any advice greatly appreciated.
DM.
I would go back with it and complain.If you dont get satisfaction then do an impression of the guy that goes into the pizza shop in "rise of the foot-soldier" film.

[Q] Screen replacement

Hey guys, today I dropped my HOX+ (International), not for the first time, but this time the glass shattered.
Ofcourse I don't want to spend buckets for some professionals, I will try to do it on my own.
Only the glass broke, touch is still fine. Only thing I noticed are 2 little holes in the glass where
the colors seem a little bit orange. Now my questions are:
1.Is it possible to only swap the digitizer (glass) or is it too hard glued together with the LCD panel?
2.Are the orange spots (you can barely see them) a problem or the LCD panel or will they
be fixed with a new digitizer?
3.Which HOX models have the same screen as the X+, I heard the international HOX has the same,
is that true?
4.Are the LEDs of the HOX+ menu buttons red or is it just the digitizer? White buttons would look great, too.
5.Do I really need replacementkits for like 60 euro with tools and all that stuff or can I do it with my own tools
at home? My father is not a professional but he already fixed all kinds of electronic things, I got his help.
6.If replacing only the digitizer is possible should I do it or would u recommend to replace the whole screen,
that would also prevent dust in the screen.
7.In many videos they didn't shut down the phone so they could test whether it worked, is that recommended or can I break smth?
That's all I had to ask, tell me which mistakes you did or some tips etc.
Hope I get some fast responses, so I know which things to order, thanks in advance

first of all sorry for the screen.
1 . you can't change the glass only because its one part at all. like the glass,touch panel and the LCD are the same piece its too hard to separate them unless you have a IR Oven. so try the whole screen replacement. the international HOX screen is ok but the capacitive buttons will be white not red.
ps:don't try to open the chase with your own unless you know what you are doing . cuz i opened mine for like 20 times and every time i was breaking something in it. Mostly the power switch flex is real easy to be broken. good luck with that.
ps2: im suggesting you to buy the original spare of the hox+ screen and replace with that. you can do it with the box one but I'm not very sure the screen voltages are the same or compatible totally..
peace :angel:
So I am back again:
I took a new One X Plus Screen and built it in the phone..
I can turn it on, my PC detects the device, menu buttons are glowing. Now 4 problems:
-LCD is not working (digitizer works fine, I tested it with swipe to wake)
-vibrator thing is not working
-speakers not working
-menu button LEDs are glowing, but u can't see the buttons itself glow, only the LEDs are glowing
I am pretty sure that everything is plugged in how it should be done, any ideas?
Don't have a phone right now so fast help would be appreciated, thanks in advance.
Edit:
-vibrator thing is actually working, it was just blocked by something
-Menu buttons can't glow because there is something between LEDs and the screen, gonna fix that later
-speakers can't work because they are in the housing, sry for that mistake
Now the only problem left is the lcd, i am going to check again whether the lcd cable
is connected or not. If you have any ideas for other reasons why the lcd could not wok
please tell me.
Another question: under the menu buttons of my old screen were 3 transparent plastic pieces,
at first I thought it were the leds, but they are actually nothing electrical, just plastic pieces
glued on the screen. What are they for, do I have to keep them?

PLS Help Which one should I buy Digitizer or LCD?

My Transformer Prime is getting ghost touches recently and also i noticed that "The touch" doesnt work at 15% of the screen on the right side. Which should be replaced Digitizer or LCD?? pls help me!!!!
This is fairly old, but I recently solved those same problem for me so I figured that answering this might be useful to others:
1. Ghost touches: this is a hardware problem, the digitizer must be replaced. But this is fairly tricky, so it might be much easier to replace the whole LCD + digitizer assembly (easily found on ebay). It more expensive, but less risky...
2. The sides of the screen not responding to touch: as far as I can tell this is a software problem. Here is how I solved it:
http://forum.xda-developers.com/tran...2#post62361792
But this solution doesn't work for everybody apparently. So all I can say for sure is that:
- replacing the LCD/digitizer doesn't fix this particular problem. It doesn't seem to be hardware related.
- it can be solved one way or another...
anybody have any solutions?

replaced screen and digitizer still unresponsive

Hello I bought a nokia lumia 920 with unresponsive touchscreen, it turns on and side buttons work, except for touch screen. So, I replaced screen, digitizer and still unresponsive. Finally, I tried lumia recover and still, the issue is the same.
Any help will be greatly appreciated

It is important to check the placement of the chips on the digitizer flex cable. After experiencing the same difficulties as you over and over again when replacing digitizers on the Nokia Lumia 920, I discovered that the placement of the chips had to be identical to the ones on the original device digitizer. Even though the digitizer fits and may actually respond to touch, the only one that will work properly is an identical digitizer (with correct chip placement) as the original. When purchasing a digitizer, verify this by comparing the flex cable. Do not count on the seller to be correct even if it is supposedly for the carrier of the Nokia Lumia 920 you have.
