A few months ago the screen on my SPV M600 took a knock which cracked it pretty badly, to the point it couldn't be used. I've rebuilt two other HTC phones in the past so felt fairly happy buying and fitting a replacement screen myself, along with the fact Orange wanted well over £100 for repairing it!
I dismantled the phone back to the screen to find it had a gold LCD cable and bought a new one on eBay.
I've now tried fitting the screen which works perfectly when the phone is still appart, but when I put the casing back together the screen goes blank. The exact point it happens is when I'm clipping the side of the phone with the volume control into place. The screen gets very bright as if the backlight is either getting too much power from somewhere or the backlight setting isn't taking effect. If I set the backlight to minimum it's most noticable as it goes from dull to full brightness when I apply pressure between the screen and board on that side of the phone.
I've tried sliding a piece of card between the screen and board to see if there was something touching that shouldn't be, but it doesn't seem to make much difference.
If anyone could offer me any advice on how to solve this I'd appreciate it.
Thanks.
I think I've solved it, I hadn't put a layer of the copper from the back of the old LCD onto the new one. It seems to be working fine now.
This is my first post here and though i read similar posts on this subject i would
like to read your opinions on this one.
I accidentally dropped some water on my touch hd and my display got damaged.The phone worked fine and so did the digitizer but the problem was that the backlight of the display was dead.At some point the backlight turned on but when i tried to input the unlock code it turned off right away (did this several times).I knew that i should replace the lcd (and the digitizer just in case).
I bought the lcd and the digitizer seperately and i managed to assemble the phone back using the service manual.Since then when i turn the phone on I hear the starting sound,i get the vibration then after a while the screen with no backlight again displays the "tap here to configure your phone" screen (after the hard reset),when i tap i get no response.
I checked the connections many times and i also used a second digitizer with no success.
Is there a possibility flashing a new ROM will solve the problem?
If so is there a way of flashing a ROM when the phone's screen is not usable?
Waiting for your precious opinions/suggestions/knowledge
Thanks in advance.
Hello,
Flashing the ROM won't solve an obviously hardware problem.
If you changed the LCD and still have no backlight, then either you bought a defective screen, or the problem is elsewhere, maybe on the main electronic board... Which would be bad news.
BTW, I wanted to change the digitizer in the apst years, but its not provided with the glue, so I had to buy a whole assembled screen + digitizer.
How did you manage to glue the digitizer on the screen ?
I aligned the screen with the digitizer and then i used small pieces of a special thin and trasparent tape to hold it in place.The tape holds the screen tight and it is barely visible, it also has the advantage that you can seperate the lcd and digitizer anytime you want with ease (though you have to be very delicate when applying it to get a good result)
I asked for a replacement of the defective lcd and i hope i will get a new one.
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

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,

Hey guys,
broke my Nexus 4 screen a few years ago - now I wanted to replace it just so I have a backup phone.
I removed the glass with some tools, and while doing so another layer at the bottom of the screen came off. (exactly the part that was broken and didnt respond to touches)
It now shows solid white color when the phone is turned on, and I cant find any info wether this layer
is supposed to come off while changing digitizer and glass or not.
Have I borked this completely? Would like to know before I waste money on the Digitizer + Glass instead of just getting a new front frame.
Edit: Okay found out that this is the polarizer which is pretty cheap on the internet.
Hi guys! I broke the screen of my lovely G2. It has a little scratch at bottom like 8mm above the back button, from the left to the right. THe back button works , and the Home button sometimes, the phone booting up like dream, showing lock and home screens, so i think Mobo is fine.
So the Question is: if i purchase this and replace the screen following this tutorial, will it work? Please share your thoughts with me Thanks in Advance!
Regards,
Mate
I recommend to buy the whole LCD + frame of the LG 2, with that you only have to remove the old screen and put the new one without replacing anything else. Many sellers offer the G2 LCD panel without the frame a bit cheaper than the complete set and you must take out the glued frame and then put in the new LCD panel... better buy the whole set.
