I think the LED that lights the "Search" capacitive button of my phone is burnt out, since this button won't light up. It's not a Rom issue because the light doesn't light up at boot, nor when I change Roms.
I was wondering if anybody knows which is the part that actually has the LEDs. I think it might be the whole LCD part, but I'm not sure, and want to be positive before buying a part I wouldn't need. Thanks.

Well honestly, I'm not so sure about that. I've been looking at pictures/videos of the motherboard and the lcd display, and from what I can tell, the bottom of the lcd display is actually between the digitizer and the motherboard, so I do not see how on earth the LEDs could illuminate through the lcd display, if in fact that's where they are located.
From the picture I attached you can see what I think MIGHT be the LEDs, only if they actually shine at an angle. I thought maybe someone here might have taken theirs apart, but I guess I might just have to take mine apart and see for myself, if I muster up the courage.
Yes, it seems to be where leds are. However, we need to buy and replace the whole lcd part to make leds work again. Thanks for your discover :laugh:

Hello, I change the screen to my Z and I have this problem.
I noticed the screen flicker when you touch or press the edges of the screen / phone. It's like if you increase the intensity of light.
The display properly reacts to the pressure of the fingers, sliding screen keyboard ...
What can happen? The screen? I open it?
The 2 Connectors of the screen with the board?
Thanks
are you using auto light? if yes try to disable it
I'm guessing it's an issue with the connections. Are you using too much pressure on the screen? I've never seen that happen on mine.

I think this is, I will dismantle it and see what happens.
Repair fail !!
Well I'm back to open the Z and I've broken the screen.
I get those lines and a black spot. 25 euros lost.
I hope it's only the screen and the digitizer.
this happened to me now i cant get anything but the lowest brightness
if you have the same as me its not the screen i think its the cable but i cant find a cheap replacement to test it plus i am thinking of going to the droid 4 if/when it gets its gsm update
Did you manage to fix the problem with your Desire Z screen, I had exactly the same problem after replacing the LCD. I took it apart and put it back together again & again but couldn't find what was causing it.
I think when you take the screen out the first time, you remove that clear glue stuff, and probably make it slightly loose. So what I did was take some of them sticky labels for printing. With a scalpel cut some very thin strips (about 2mm in width and almost the full length of each side), folded them into an L shape and stuck them aroud the 3 edges of the LCD, before sinking it into the housing and the problem is fixed.
Just in case I've not explained that very well, here is a really bad diagram.

Hi guys,
What could be the possible reasons for a touchscreen and the capacitive buttons to stop working?
I purchased my Huawei U8800 only very recently but it was purchased 2nd hand. The phone came pre-installed with a custom rom, which is this one here: http://forum.xda-developers.com/showthread.php?t=1481168
I've had very minimal use of it ever since I received it, due to the reason that I have exams as I'm an UNI student. Therefore, I haven't modified the phone in any way, i.e I have not overclocked it or flashed a different kernel or recovery etc. The only thing I've done is installed GO SMS PRO and used it for txting and calling, that's it.
At first, everything seems to work fine. But on my 2nd day of use, the touchscreen started acting weird, where the right hand side of the screen stops working for no reason, as well as the 2 capacitive buttons on the right half of the screen (HOME and SEARCH). Then after a while, the BACK capacitive button on the left half of the screen stopped working, and eventually all 4 capacitive buttons and the entire screen stopped working.
The phone still turns on, but the entire screen doesn't pick up any finger input and there isn't any haptic feedback or vibration from the capacitive buttons. When I boot into the recovery, this is also the same.
So I contacted the seller about this, and he advised me to flash the Cyanogenmod 7.2 rom to see if this fixes the problem. It didn't, the touchscreen still doesn't work.
I'm wondering if this is related to the digitizer, which is the part of the phone that sense your finger inputs? If not, what are the other parts of the phone that could relate to the capacitive buttons and touch screen?
Definately a digitizer problem. The capacitive buttons are part of the touch screen, the touch screen is extended over the bottom of the display.
You should buy a new one from eBay or similar. If you want to buy it with a frame (black part on the front), you will have to open your phone to see if the front speaker is big or small. There are two types of front speakers and they are not cross-compatible. If you just want to buy the digitizer, you will have to remove the old digitizer from it's frame and add some glue on the new one to make sure it won't stick out.
If you don't want to mess with your phone, I am sure there are paid services that will do it for you, since replacing the digitizer is fairly easy.

thanks for your reply mate!
Ok so I've found this one here:
http://www.ebay.com/itm/Original-To...Glass-For-Huawei-U8800-Ideos-X5-/170721993712
Since it says it's "original", I don't have to worry about the speaker problem right?

They are selling the digitizer, so there will be no problems as it's only the digitizer glass and not the frame around it. The frame itself is holding the digitizer and the speaker so that's why there may be issues when buying the front cover.
If you need a disassembly tutorial, check my Mediafire (signature) -> Documents -> U8800 Basic Maintenance Manual. It's the official disassembly guide so you can be sure you are doing it right .

Wait, that doesn't have the frame around it? I thought the black part surrounding the glass is the frame? I'm confused.......
I just want something that looks exactly like shown in that Ebay listing photo, where it has that bit of the connector part that you push into the motherboard (or whatever it's called on the phone).

On your listing, it does not have frame.
If it's without frame, it is simply the front glass with connector. If it is with the frame, it has the black curve too (and speaker with led).
See this:

With frame.
Hope it makes sense now

Yeah, but not much. Maybe you don't need to add any glue at all, the old one might hold it too.

hi blefish
just posted a similar question:
http://forum.xda-developers.com/showthread.php?p=39201328#post39201328
is it the same solution? (the 4 buttons at the bottom do not work as well as the lower half of screen)
my speaker is 15 mm by 5 mm long (i looked inside). is it big or small?
all the ebay posts do not mention a frame - i will be happy not to mess with the glue
thanks

Hi guys,
I did have the same problem with a Huawei G 510. Digitizer broken and replaced, but still not working.
I have no action on screen. It lits but i can't press any button. Either the 3 buttons are working.
Checked the plug, checked some voltage in the pins.
Any other ideas ?
Thanks in advance,
Miltos Matt
I Broke the screen and replaced it (not replaced it by myself).
The screen they gave me is kinda weird.
The LED circle is really big now and I can see few colors when it blinks.
Hope you guys understand what I mean.
What can I do with that?

I have replaced multiple screens , that is LED/Digitizer combined and no problems. Can you describe what exactly what is happening in a little more detail?

Of course, sorry for not being clear.
The screen broke and I changed it in a lab.
They assembeled a screen where the LED cut out is really clear and can be seen with out difficulties.
Not just that, now when the LED blinks I can see the whole LED cut out shines instead of just the little "flare".
Hope this is clear .
Thanks!
Sorry for bad English.
It's probably not original screen. I had to replace the display and I ordered cheaper one. Hole on the led was completely transparent. In the original display the hole should be blacked out.
Hello,i don't know if this is correct section where to describe this problem,but anyway is just an question so let it go.
Like title says,on Nokia 6 there is a problem with buttons design or i broke them ? Because i can see the backlight from LCD through power button,its just a very small space betwen aluminium body and those button,
where you can cleary see the light from screen.
I observed this after i did an hard reset,and i pressed maybe a bit to much power + volume up buttons,but they're working fine.
Also remember,in order to check this for me,do it in a dark place with LCD brigthness at least 50%,and move your phone whille looking at those buttons,you can only see the backlight from two differents angles,at least on mine.
So please check and report back to me,to know if this from design of the phone,or i broke them in some way.
My phone is global version,TA-1021,my english is bad sorry for that,i hope you understand me.
Normal, my ta-1033 is equal.

I have the same issue with my phone (Mi A1), I broke my screen and then replaced with a new screen and updated with July security.
note: I didn't notice the button light up or not when got it fixed or before the update.

so. i am currently replacing my phone screen and noticed i have a ribbon missing on my new display. i think that this was the case with yours too. from what i have found that is the connector for the capacative button lights. updates wont do anything in that case
