Hi,
I have a problem with XDA - it is stuck at the align screen and keeps looping the cross over the screen forever.
I have reflashed rom a few time, I have disassambled the phone - cleaned the contacts, cleaned the screen, removed the schotch from the lcd 4 connectors. I even tried to glue a big piece of schotch to the screen pull the touchscreen of the lcd a bit...
nothing helps so far!!!
Do I need a new touchscreen? I really would like to fix this one, because it shouldn't be broken - it looks so nice and clean!?!!!!
Please help me!!
I found that pressure applied to the bottom left corner of the touchscreen behind the today screen button will cure touchscreen problems. When dissasembled it would be the area where the 4 leads branch off the touchscreen. I tested by slipping a doubled over piece of paper under that left corner (with the unit fully assembled). It put just enough pressure on that area that the touchscreen started working again! Try it, might work.
Thanks, but nope - stucking a paper under the casing didn't help.
I have managed to get pass align screen by deleting welcome file on PocketPC/windows/startup, but still the screen is faulty as the bottom and the top part of the screen doesn't respond to stylus!
What could this mean? Is there something wrong with the robon cable? Could reattaching the ribon cable help?!
Guess what! Just fixed the touchscreen - everybody said it's impossible - I don't know how I did it - just removed the ribon cable and soldered it back - it worked for me!!
Thanks all!!
XDA iis digitizer replacement and align screen solved
Ok to start with it is nearly impossible to solder the ribbon from a new digitizer on to a ppc lcd. I screwed up a screen trying to do that with a so called fine soldering iron but this is micro soldering, looks to be only possible by a machine. Dont glue it either as i've heard its bad too but if some one has had success then post and let us know. I just sticky taped it to the 4 metal connection lines. The ribbon is slightly see through and can easily line up.
Now when I had done this the screen align kept cycling. Yes even up to 20 times would not fix it but if you go back to the ribbon connection and make sure it is exactly on mark then you'll know the connection is ok. If the align screen responds to your taps well then it is just either the ppc getting used to the new digitizer or what I found was shuffling around the screws and making sure the insides of the ppc were snug and nothing pressing too hard on the lcd. The comment on placing a piece of cardboard was a good sujestion as when I screwed the whole thing together it suddenly aligned.
When the ppc finished installing, the alignment was a bit off by half a centimeter so i ran the align screen utility from settings again and it aligned! Now it works. Fingers crossed.
No response from a seemingly perfect touchscreen.
Hello guys it seems you guys have mastered correcting touch screen problems. If you would take a moment of time out of your day to help a dumb college kid. I have a SX66 and it has worked perfect and has remained to be a cool phone thanks to this site and the developers. I have retraced my steps a million times and here is what happened. I was surfin the web on my phone at school and the battery dropped off. I put the battery back on but the phone would not power up. 30 minutes later I tried my backup battery and bingo it powered on. But the touchscreen does not work at all. I took the phone apart and made sure connections were good and all was good. And as a last resort I reflashed my copy of wm6 to the phone. There is no cracks or blemishes on the screen. Any ideas will be greatly appreciated
hey,
I had a problem a few days ago where some parts of my touch screen (near the home, menu, etc. buttons) started to not work. and today when I woke up, the whole screen is not working. It seems to respond every now and then, but barely.
I'm assuming this to be a hardware problem, but I am not sure. Anybody had a similar problem before? disassembly would be my last resort, how should I go about fixing this? Thanks.
I have the same problem. about a half inch band across the very bottom of the screen. Weird thing is sometimes the whole screen will become unresponsive (if it stays on for too long) then turning the screen off and on and unlocking the phone makes it go away for a while. The digitizer glass in my phone seems to need replacing. I've scoped a replacement out online (don't have the link) for about 30 bucks. there are also many assembly/disassembly videos for the phone. Looks like it will take a lot to get the digitizer out.
I was having the same problem... Just replaced the digitizer and still have the same issues... anyone have an idea?
I have a similar problem but with the soft keyboard. It becomes unresponsive very often..tried many roms and diff softkeyboards but the ptoblem still there

Hi everyone,
I've had my Desire Z for little over 2 years now and two months ago (was running CM7.2 at the time) I started getting a weird issue where my touchscreen would only be responsive when the keyboard was slid out (so the opposite problem of what quite a few other people have reported where the touchscreen becomes unresponsive when the keyboard is out). The status LED would also stay off whenever the keyboard was closed, and the keyboard backlight didn't come on anymore at all. Also, I had to make sure that the keyboard was slid out during boot, if the phone booted without the keyboard out the screen would not become responsive at all until after another reboot. My earpiece speaker stopped working around the same time so I was wondering whether it was just an issue with the flex cable becoming a bit loose, but the touchscreen would consistently start working again when I flipped the keyboard out, and also the physical scroll button on the top bit would always work, so I was still hoping it would be some weird software issue.
I then upgraded to Flinny's (amazing) Andromadus ROM (build 22, complete data+dalvik wipe) after which the keyboard backlight started working again, but the rest remained pretty much the same. Since then the touchscreen issues have been getting worse, so that I sometimes have to flip the keyboard in and out again a few times, or turn the screen on or off with the power button several times before it becomes responsive again, but then it tends to work fine until I lock the screen again, with no noticeable dead spots anywhere on the screen. I've had days where it worked all day without problems (except having to flip out the keyboard, that's been a constant for the past two months), and then today I haven't been able to get the screen to do anything at all even after dozens of reboots.
I've already bought a new digitizer and am all ready to put it in (I'll have to replace the broken earpiece anyway), but was wondering whether anyone has any thoughts on whether it could still be a software issue after all, or if anyone has experienced anything similar? The thing with having to flip the keyboard out to get not only the touchscreen but also the status LED to work is just so weird and makes me doubt that it's a pure broken digitizer or lose flex cable issue, so I'm wondering whether it would be better to first try reverting to a stock ROM before taking on the messy sticky glue stuff (I should be fine but still, never done it before)?
Many thanks!
From what you describe my best guess would be the main flex cable is what needs to be replaced. Flash a touch based recovery and see if you have the issue there as well, if so its very unlikely that its anything but a hardware fault

Thanks for the heads-up, I've been playing around a bit more with software and I do manage to get the screen working again occasionally, typically after the second boot into a newly flashed ROM or restoring a backup, and only until one or two reboots later when it becomes completely unresponsive again. I've tried CM 7.2.0 as well as Flinny's Andromadus 10, and it is only complete flashing that does the trick, cache wipe or factory reset alone does nothing. The two occasions where the touchscreen worked were still limited to when the keyboard was flipped out, and it also had to be flipped out during boot, otherwise nothing would work. I've learned to navigate my way around the phone by just using the hardware navigation button, but I'll have a close look at the flex cable when I take it apart to replace the earpiece speaker tonight...
Hello,
so I took my dear phone apart yesterday to replace the broken earpiece - everything went fine but after reassembly the replacement earpiece isn't working either, which leads me to think that all those little broken bits might actually be related to some contacts being a bit lose, all in the same region. Should've thought about that earlier really since the earpiece and the LED (only works when keyboard flipped out) are both in that top region that the digitiser data presumable also has to run through before passing through the flex cable.
In any case, I also took a picture of the flex cable which is slightly bent but doesn't seem straightforwardly damaged (see attachment, that thing on the right is *not* a rip). Think it's worth trying to replace it anyway?
What was truly bizarre is that after the first boot following reassembly the touchscreen worked quite consistently for the entire evening - I thought I might've fixed a lose contact by un- and replugging the digitiser cable, but then the screen went nonreactive again at some point. I wonder if the working screen was again actually related to some software reset caused by the battery being taken out for so long? In the meantime the actual screen and trackball are still working away perfectly. Bizarre.
Just to let people know the solution to the mystery: the increasingly odd behaviour was actually caused by an initially small rip in the flex ribbon cable that got bigger and bigger - it's actually half-visible in the picture I uploaded above, only that the rip is where the cable comes out from underneath the case, and not where it's wrinkled!
Just in case it could be useful for anyone, here's the (top half of phone) components in the order in which they failed on me, which I guess corresponds to the order of the respective data lines in the ribbon cable (from the top of the phone towards the center):
environment brightness sensor (I thought that the sensor had been broken for almost a year, but as soon as I rebooted with the new flex cable I noticed how my phone stopped shining into my face at full brightness - if your brightness sensor gets stuck reporting the same (low) value this means your flex cable is on its way out!)
earpiece speaker
status led
touchscreen
screen (non-alignment with edge of screen, visual artefacts)
screen (fade to black/power interrupt)

I'll for sure keep that in mind. Mine is still going strong for the time being, but it's good to know some warning signs if I need to replace parts or if it's time to get a new phone

Replacement parts all the way, the repair was 15$ and it feels as good as new! Well, it could do with a new battery but that's just another 5..
Just realised that the proximity sensor should actually be added to the very top of the list - just noticed that faint red light when taking a phone call, don't remember seeing that in almost a year :]

That's not a bad cost at all. I know I'm going to have to replace my keyboard in probably 2 months or so (maybe sooner) because some buttons are starting to not work. Other than that fact my phone is currently still going strong for being going on a 3 and a half year old phone
Brought a second hand p8000 couple days ago thinking it had screen flickering bug that you use Nova launcher to solve but turns out the digitizer is broken or loose I think. When I switch on it work fine but when I touch home or left capacative button they don't work.
After some minutes the home and left button start to work then all of a sudden the screen goes bezel and starts opening unrelated apps and pulling down status bar without me touching
The screen itself looks as though it's coming away from frame in middle section
I took apart last night and when I touch digitizer plug at top it also starts the bezerk reaction
Anyone have any ideas how to fix this? Is it just broken digitizer ribbon cable?
Thanks
In case anyone has same problem and found this through search.... I just wrapped sellotape around digitized cable as it was shorting out on frame
friend of mine has the same problem with p800. looking for some solution. just seen similar threads on official elephone forum, but no answer from elephone or some tips
Warranty expired a long time ago. No visible screen damage (some chips on the sides), it was dropped a lot unfortunately.
One morning I woke up and my phone had a strip of 1cm dead touch screen at the top (it was partially under the pillow so there was some pressure involved, like everyday though). So I enabled landscape gyroscope transition mode and it turned out to just be a minor inconvenience.
But now it developed another issue (after another drop), earlier the top of the screen was completely dead no matter what. Now it has expanded downward by an additional 1cm but it's not exactly always dead and the bottom 3cm has also become semi-dead:
It can still work if I hold my finger in place for a few seconds, and it seems to work perfectly fine so long as the touch originates from elsewhere on the screen - it tracks perfectly if I lead it into the semi-dead touch zone. I do not know enough to even guess how that happens, initial touch detection differs from touch tracking?
I do not know enough about touch screen technology to know why this is happening and what it means, I do not want to buy another phone - I have considered just buying another G3 and performing a motherboard transplant but I thought I should ask here first about this. Can it be fixed by me with an easier method?
