Hey guys!
I'm experiencing a very strange and annoying issue with my BA, and I was wondering if I could get some input from you.
So, here goes:
The touchscreen (not LCD) in my unit was broken, and thus I decided to fix it. I purchased a new one off eBay a few weeks ago, and just yesteday I proceeded to install it. To my surprise, something seems to have gone wrong.
I power up the unit, make my way into "Allign screen", and then the last "cross" that I have to touch rarely clicks in. On the other hand, when it does get detected, it simply restarts the alligning process.
What I've tried so far:
- allign right after installation -> no luck
- hard reset (on WM2k5_v4_R2.1) -> no luck again
- opened up the unit again, repositioned the screen -> nothing
- upgraded to Logout_WM2K5_5.4.03_HN -> still nothing
Right now I'm out of ideas, and I was hoping somebody here has some. Do you think the new touchscreen might be flawed ? I'm already discussing this issue with the seller.
Thanks for reading
New touchscreen or a refurb? Same type? (toppolly / sony) Sounds like it's been stripped from an old unit to me as it's not recognising the taps in the right places - can you see somehting like a liquid spill anywhere on the panel? This is what it looks like when the overlay touches the glass.

That was in fact my auction. Looked like brand spanking new to me, not one single stylus mark, and also had the protective sheet on. Of course, I might be wrong
Also, no liquid spill visible anywhere.

I bought from him also and am yet to fit - I got the completley wrong module :-(
Richard
What do you mean wrong module ? The "tip" of the flex cable ? Mine seems to match with what was already there ...
Hey NSD!
I purchased the exact same module for my Himalaya device, after the touchscreen being cracked.
My father, who is an electronic engineer, soldered the flat wire from the touchscreen onto the rear side of the LCD with normal copper wires. Unfortunately I have the exact same problem a you!
After attaching the entire LCD (+touchscreen) onto the mainboard, and supplying power from the battery, I'm not able to go past the Align Screen section!!!
The touchscreen is from the manufacture 'Asian Media' (I think so...).
It can't be a coincidence, that both of our touchscreens don't respond to tapping!!!
Anybody been able to get this problem fixed??
Any help would be appreciated!!!
Kind Regards,
Tony Schattat
I never replaced the touchscreen of my BA but I have replaced the screen of my ex ipaq 6315 once.
And one thing that I know is that sometimes the screen align process is different from the normal, I mean, it keeps repeating and repeating again many times....until the unit finally passes the align step and finishes the configuration. Actually I´ve "aligned" the screen more than 30 x (when I replaced the screen).
It happened just once and then I had a completely normal unit.
hello,
I managed to break my LCD of XDA IIi, I managed to find the screen from ebay but i'm confused as ther are two models is says the first generationa nd the 2nd, one with silver flex and the other with a gold flex.
Which one would fit my Alphile, O2 XDA IIi. Please help me to find one. I'm in france...
take your xda apart.look on your board,if its a generation 1-it will be a slide in cable/a generation 2 is a clip on version.i have a version 1[slide in] for sale if you need one.pm me
I also broked/scratched my XdaIIi screen (my 3 years old daughter ), the phone continued to work, but when i rebooted it, it started to ask me to touch the target to align the screen.
But it doesn't work...no alignement...
When i touch it i can hear the plastic cover, but the screen is also scratched/broked.
Any solution?
Kind regards
It seems that you have to change a new screen for your phone. You can go to the nearest phone store and fix it. I always think the phone store is safer than online shop cause you can watch when they fix it.

i tried, they wont cover accidental damage. And my warrantys been voided since someone opened it up..
I bought a second hand phone and it did turn on however there were a numbers of problems with my phone, it had a power button that didnt work, unresponsive parts on the lcd and a quiet in call speaker.
Your best bet before trying to replace the whole pcb is opening your phone using a teardown guide
http://tjworld.net/blog/htc-desire-z-tear-down
Make sure you read it a couple of times and go through the pics so you know what your dealing with, find the power button, make sure its intact and adjust the ribbon cables.
Otherwise just find a cell phone repairer on a classified ad like criagslist or kijiji.

I hate to say it, but it was second hand for a reason. Ever try switching the battery? How about changing the power supply?

Yes. Start simple. First check your electron hose to make sure you are getting power to the device. Also check the battery as well as the prongs that connect with the battery tabs. If things are good there, then think about tearing into the phone.

no no, dont say that. This phone was fine for 3 months, i dropped it at a club i went to and water got inside the phone....i took it to 3 repair people and they all said the Main PCB motherboard is damanged (water) soo does anyone have any idea where i can find a motherboard?? i have no problem with costs of replacing it. As long as its not more than the phone itself.

You didn't mention water damage in the OP. You said something was loose. Water damage is completly different.
Try ebay.
Hey i found these 3 ads on ebay...do you guys think that a swap of the motherboards would be fine? heres the ads. I contacted the seller and they said the battery was used and thats it but phone seemes operational....i know its a risk, but is it worth it guys?
..need help on this one.
why swap the motherboards if the new phone is working fine. Just transfer data and you're done surely?

Reason being the other phones have minor problems, like speaker doesnt work, or some of those phones wont pick up signals and i think thats due to a bad radio flash or if i just flash a radio everything should be working fine.
can someone please clarify this? if i buy a phone with a speaker problem and transfer the main PCB board to my old phone...will there still be a speaker problem? or is the speaker a separate unit itself and not related to the pcb board?

one of the phones i am bidding for says it might not be able to guarantee a connection to mobile network (send sms,make calls) could that be a radio flash problem? would i be able to fix that??
another is one of the phones boots on and shuts off, i take it that could be a bad flash or something? its only about $20. just trying to weigh my options cause the new phones are lkike bidding for $350 lol im not that rich yet
I found out that my MOTHERBOARD is fine. There was water damage but not enough to go inside to the main board! My dad tested the battery voltage and found i wasnt getting any voltage.
i went to future shop and found a lady to let me use her battery and sure enough the battery was working and phone powered on!!! so i guess my battery was shot from dropping and popping out of phone while recording a video.

ordered these from ebay....are they any good? they look decent
Those look like the batteries I got. They were about 1/2 of the claimed mah rating. Worst case, they wiill get you running, and that charger is pretty good.

noticed that my touchscreen is becoming unresponsive lately so i thought that changing the multitouch might solve it. the thing is, after selecting 4 touch, touchscreen becomes totally unresponsive. i tried wipe and even flashing stock os but touchscreen is still the same.
did i screw up my touch screen? how will i know? any known repairs or fix.
thanks
Sounds like your digitalizer (the glass above the screen) is busted and needs replacement. If your phone is under warranty, claim it, if not - get a new digitalizer and if you can't change it yourself, take it to a repair shop.
Changed the digitizer but still no response
Got a headache? It's all in your head!!!
switch ROM
You said that you flashed back to stock, but how about flashing to another ROM, I mean one that has a completly diferent multitouch enabler... that might work.

i was able to flash stock and it means i have no root nor recovery. and adb debugging is not enabled. i am out of ideas how i will be able to solve this.
After flashing stock ROM do you face the same issue with a new Digitizer?
yes. doesnt respond to anything except volume and power. even the 4 touch buttons doesn't work. i was thinking that i have received a bad digitizer or it is a motherboard issue. with the latter i have no idea how to check

I had recently taken my Defy to a service center. I just wanted to change the earpiece and the side casing. While replacing the side casing (while removing the Digitizer) they damaged the digitizer. The main touch portion was working but the 4 soft keys were not. They replaced the digitizer and everything was fine again (had to pay for it )
If you can carefully handle the phone, you can open up the casing and try reconnecting the digitizer to the board. (Do not remove the digitizer from the casing only reconnect the cable).
Replacement is better done by a service center as it requires careful handing.
I did open the phone, removed and reconnected the cable, still the same. also tried 2 new digitizer still the same result. I guess it us the mother board . Any ideas where to get replacement board ?
Thanks
Got a headache? It's all in your head!!!
i have got the same problem like you and i have solved it.
Do compass calibration like spin the phone 3 times in flat condition (laying down face up), then have the phone standing up and rotate 3 times, then on one side, rotate 3 times and then move your defy in the shape of number "8" in the air. Re-open the screen. it is suppose to bring back your screen work like it was nothing happened.
only for my defy i've tried never did this for another but from what i see you have nothing to lose here
Tried the calibrating thing and also a new digitizer. doesn't work. So it is the motherboard.
Anyone knows where to get mother board
Got a headache? It's all in your head!!!
Getting a new board is like getting a new phone - new IMEI, price for the board should be very similar to the pricw for a new phone too. If you think about it, it IS the phone. What's there in the phone other than the board a screen and a digitizer...
Guess you're right.

Did you replace the combo or just the touchscreen? Did you test it before when everything hooked up before taping it to the bezel? What kind of tape did you use? You may want to post a higher resolution thumb of the area where the ribbons connect to the board.

Nope I didn't test it but I put some tape that is easy to remove so i just removed it checked all connections, nothing seems wrong. I attached some new photos (best quality i can get right now). Also I replaced the full combo lcd+touch. Thanks for the reply.

Nothing looks out of the ordinary in those pics, though I don't see how one can replace the combo without removing the boards. Can you explain that as some step in the procedure might cause this. Instead of guessing too much, let's take one thing at a time.

I can't post links so you can search youtube for "Nexus 7 Screen Replacement 2013 model, replace the glass and fix the LCD - Repairs UK" and that's how I did it. And the thing I know I'm missing is the tape he takes off at min 2:43.

Any revision number on the digitizer? I know that there are different revisions of the daughter board and that if your tablet came with a 1.3 board and you replaced it with a 1.4 board the touch would not work, but I don't know if it is the same for the touch screen

I looked at the clip, and it seems ok, except the emi tape hanging from the frame would not stick to the back of the lcd that way. I don't know that it should make a difference since yours is totally unresponsive to any touch. Same case with the missing one going on top of the touchscreen connectors.
There have been cases with other Asus models where you'd need to re-flash the touch firmware before it works. If the daughter board had been working before you replaced the screen, you can either (1) re-flash a stock rom (444 to be sure) using fastboot, or (2) if you're on custom Kitkat (I don't know about Lollipop), re-flash said firmware following the instructions HERE. Remember you have to have one of those kernels mentioned therein installed for the firmware to stick.
I don't know that the touchscreen version should make a difference since they all use the same rom wih the same touch firmware embedded. Unless the rom contains many versions that would automatically select one fitting your hardware version, in which case you should flash the official Kitkat.
Failing all the above, I'd conclude the touchscreen itself is bad. It's a rare occurrence, but has been known to happen. If you bought it from a reputable seller, you should be able to get a replacement. Don't hesitate to ask if something is unclear. Good luck.
I have the same problem. I bought two digitizers and lcd, and both times the problem is the same. I checked for a rev number on the digitizer, but with no luck. The tape I used was M3 300LSE. Already flashed 4.4.4 stock firmware on Flo kernel, but it didn't work.
I can't believe I bought TWO broken digitizers from two different sellers. I will retry the flash...
I tried to see if there is any recognizable serial number on digitizer, and I explain what I found here: http://forum.xda-developers.com/nex...xus-7-2013-touch-screen-unresponsive-t3035124
I'm sorry I'm posting about same issue in two different threads, i did open the other one cause I didn't see this one...
