I just dropped the remote of the tv on my X7500 and now there is a small dent in the touchscreen. The LCD is not damaged. Does anybody know whether there is a fix for this, eg can the touchscreen only be replaced, or is it part of a total module with the LCD panel?

As far as I know it is possible to detach the touchscreen from the main LCD.
The touchscreen is a thin film surrounded by a metal frame which clips over the edges of the LCD (like the top part of a board-game box!). It is fiddly to remove without the right tools and is furthermore connected by a small ribbon connector.
It may or may not be cost-effective to buy the touch screen - I have a big scratch in mine and would like a new screen, along with some other bits but I don't know where to source components.
i cracked my digitizer a while back, and ordered a replacement. i used double sided tape to install. the first digitizer worked great, except only the top 10% of the screen was not responsive (pretty much the width of the task bar) so i contacted the people i ordered the new screen from, and they just sent me a replacement. i installed the second digitizer, and this time none of the screen works.
i tried to make sure both times not to put the tape to wide so it doesn't overlap into the clear screen part, only the black, but could this be a tape issue? anyone else have trouble with installing where parts or entire screen didn't respond?
thanks for your help.
Are you sure you have the digitizer/lcd ribbon in all the way to the connector on the motherboard? When I first put everything back together when I changed a digitizer, touch didn't work at all for me initially. At first I thought I had a bad digitizer. Then I looked closely at the ribbon and connector, and there's some flaps that stick out to the side on the ribbon cable. Make sure you push the ribbon in until the flaps stop you from going any further.
I replaced my digitizer recently and when I put the phone back together and turned it on, the LCD looked different any thoughts or suggestions. I looked through some other threads but nothing described look like the problem I am having.
I guess the digitizer isn't original and polarizes the light in a different way, giving the strange optical effect.
Another issue maybe the digitizer is stuck tightly against LCD, try to put between the two a strip of thick adhesive tape around the edges, avoiding tight contact.
Or worst, maybe you damaged the LCD while disassembling, to verify this lift the digitizer and see if it looks the same or not without digitizer.
It looks as though it is a similar problem to * HERE *

so weird question. but meh. im more of a 360 modder. not into phones.. i try to fix them bc im descent with electronics.
but anyways my point is.. anyone ever tried replacing the leds on the button panel?
white 0603s are typically the same as blue. i use alot in controllers and rol boards on the 360.
i got about 50 blue 0603s. and thinking of giving it a shot
Butoon leds are placed on FRONT KEY KEYBOARD MEMBRANE PCB. Search littlebit google and you find what leds they use on this membrane pcb.
Hint!
For getting out this membrane pcb you must detach middle case at lcd/digitizer combo. To attach these back you need two sided tape later.

lol. i got the phone disassembled lol. and they are 0603 smds. i use them alot. but idk the voltage of them. if the blue requires more voltage then the white is giving then they will barely burn or drain the battery quicker.
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:
Without frame.
With frame.
Hope it makes sense now

Ahh ic ic.....so would I need to use glue to stick the digitizer glass onto the frame?

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
