Defy touch screen partly not working - Defy Q&A, Help & Troubleshooting

I have a green lens defy which was running cm7.2 stable. Earlier today i opened it to see if i could get rid of a crackling noise from the earpiece. I opened and closed up the phone and the crackling stopped however the bottom half of my screen started giving trouble.i can control the top half perfectly but the bottom half keeps behaving like im touching and leaving the phone so when Swyping i get it as if ive tapped multiple letters rather than drawn a line across them. Ive cleaned out the cache and even gone back to stock to no avail. Ive done the obvious of reopening phone and checking the connector between the digitizer and the circuitry but thats fine. I removed and inserted it multiple times with no change. The bottom half seems to pick up taps properly but no drags and all drags that are picked up are pick up as horizontal lines. Ive even adjusted the digitiser connector while the phone was powered on to see if it was a loose connection of sorts but to no avail. Contacts and the like are clean. Warrtny expired 10 days ago :/ . Any ideas?

you must change the touch screen ok ,there is option to reassemble ok .iam also having this trouble in touch screen ok .i changed the touch screen in moto service centre ok.it cost 3500rs

I have the same problem in red lens
Hello, I had the same problem with one red lens, the touchscreen was broken and replace it (only touch unframed), then manually pasted what the problem started exactly at the top, I thought it was spoiled (badly damaged pegadao ) and change it again, but still the same, so I thought some of the software and did everything and nothing, now I buy a touchscreen with frame to avoid having to manually paste if that works. What do you think? What do I do?

Please ask all questions in the Q&A section. Thread moved there.

Ive ordered exactly the same thing. Mine got lost in transit so i just ordered another. it could take a month to reach but ill let you know what happens for me.
Let me know how yours goes.

Help! Stuck on Align Screen!

Guys, I hope you can help me!
I was using my Imate Jasjar when it was accidentally bumped by another person. the Jasjar fell but it wasn't that high and the floor was carpetted. However, I noticed that whenever i try to tap on the Start button on landscape mode, the calendar application opens up! And when I try to tap V-Bar on the other corner opposite the Start button, the Contacts application opens up. Basically, the soft keys on the bottom screen are the one opening up even if I'm tapping the ones on top! If I tap the bottom soft keys, I thought the Start button or my V-bar would come out but still the Calendar and Contacts applications were the ones that opened. Basically the everything on top cannot be tapped!
On Portrait mode, I can tap the start button but when the V-Bar was tapped it still opens the Contacts application.
I went to Settings then Screen to re-align the screen. I thought it would solve the problem but apparently it didn't! I was trapped in the Align Screen section giving me an endless loop to tap the 5 areas of the screen.
I now did a Hard Reset, and now I'm forever got stucked to the Align Screen part.
What am I supposed to do??? Please help!!!
Hi,
Seen the same problem... Try to guess the error margin of the alignment...
for example instead of tapping in the center of the cross try tapping on left or right... Since your screen isn't aligned you can't press on the center...
Now the problem is hardware, not the MB but the LCD...
After tou figure out the margin error, the Universal will resume and then you ca align the screen via Start->Settings->System, align screen
I'll try to know more about this problem asking my friend.
Best of luck
thanks for your reply!
i also believe that it has something to do with the LCD. there are no cracks whatsoever. problem with the aligning is i have to keep on guessing. and if ever i do align the screen successfully, i'm not sure if re-aligning the screen in Settings would solve the problem.
i would appreciate though if your friend or anybody else can shed light to a solution.
This is a simple problem to solve ;-)
When the allign screen is ON and you have to make the first tap on the crosshair (just before you start clicking away to allign your screen), twist your display from landscape to portrait mode...
Now continue to allign it as usual, and you should finish successfully!
Cheers,
San
unfortunately, after following your instructions, i still went on an endless loop on aligning the screen. i'll try to reflash the rom and see if it would work. i hope it does...
i updated my ROM. still stuck on the alignment screen!
any more ideas?
To be honest, sounds like your screen is broke. Even if you got it to align, I doubt it would be very usable. I think you are looking at repair - if there's no visible sign of damage, you might get away with a warranty repair.
Cheers,
Steve.
Hi
Few months back i've got exactly the same problems (odd LCD behavior, impossible alignment, etc...) with an HP4700. I went to the service center and they had to replace the LCD screen. They did not charge me and take it under warranty. In my case the unit did not drop and i made it clear to them. I would suggest you go back to the service center and forget about the drop in your problem description .
Cheers,
Bruno
I had the same thing happen on a HP 3700, I did not even drop it all i did was install the Quake game for it and after a few days the screen alignment went a bit out. It was usable but definately out by about 1 cm in each direction. The unit had not been dropped. I went into the allign screen utillity and ended up in the infinite loop. The only way to fix was a new screen. But unforunately it was no longer under warranty. The screen consists of 2 separate parts the lcd and the touch screen bit. In my case the lcd had no issues just the touch screen. Very annoying but there you go.
Search your soul and do what you feel comfortable with.
Good luck
Charlie
thanks for all your replies!
i've made several searches yesterday with similar problems (even if they're using different PPC models) and they all ended up sending back their units for repair. there's even one who posted in expansys with the same exact problem!
we'll be sending it back through expansys (we got the unit from them) and hopefully get it back before the end of the month. and yes, i won't tell them that it was dropped, he he :twisted: and they won't find evidence either on the outside because there are no physical damages. what a start of the new year for me <sigh>
right now i'm back using my XDA IIi.
thanks for all your support! this is my first thread/topic in this site and it's so unfortunate that it had to be sort of a negative one. looking forward to be active more here!
Hello there
This might help (I am currently wrking with 200 PDAs so have had this a few times)
THere may be a iece of dust/biscuit crumb etc, under the edge of the casing above the screen, try using a post it note or paper and go around the casing/edge of screen, this should clear the screen of anything that may be causing this problem.
THis worked for me on the majority of non-aligning screens

My story was, one day when I needed to twist the screen, it was a bit stuck so I twisted a bit harder, yes it went back. Then few days later, the mis-alignment started and since then I have been keeping to do re-alignment my screen.
My screen is mis-aligned once every 2 or 3 days or even few minutes then I have to re-align by using WM5's alignment program. It sometimes takes me 2 or 3 times or even one time.
The most anoying thing is it keeps forget after aligned screen.
Now, certainty, I don't think it is a screen problem because after running alignment app, it correctly pointed into the right spot but then it forgot where the right position was.
I have done the upgraded ROM ( even tried Ivan AKU 3.2 ROM ) but problem still persisted.
I just tried clean up the edge of screen, finger cross, hope it fixes my problem.
Bad thing is, I bought my device from UK and I am living in Australia so therefore, my warranty is definately invalid. I don't want to spend 200 AUD for the new screen ( unless I am 100% sure that LCD is faulty ).
Anyone has any idea or even a better suggestion because I don't see many people having this problem.
I suspects that maybe the flex cable got ripped but not totally ripped. Don't know , please help me out on this one
Best regards
Anyone has any idea about my problem ??
One question :
I know that the flex cable has 2 connectors ( one is for LCD display and another is for LCD function ). Now does LCD function relate to the touch screen function ? and if one tiny wire of the function cable got cracked, but not totally cracked, will it affect the touch screen function ?
Other thing, does WM5 store any setting relating to screen alignment setting ? If yes, where is it ?
Thanks
Hi, from another forum, it only help to bypass the alignement loop:
"here you go theses are simple steps to bypass the touchscreen alignment.
Install you activesyn blah blah blah when it finds it go on my computer and go into your PDA device
go to windows startup and delete the Welcome file
after that give your PPC a soft reset and BAM u by passed the screen now get a free desktop program liek pocket controller from the internet it will automatically install on your pda and BAM you can control your pda add music and whatever
but now if you want to click stuff on the road get pen irazu just search on google and send it to your PDA then go to file explorer and double click it and you got a cute little mouse program that you can use like a stylus"
also try this little soft:

Hi godtakeit!
I've had the same problem a few weeks ago (and still having it from time to time) and for me a slight (very careful) bending of the screen makes it work again. It seems to me that there are connector behind or near the display which has some loose contacts.
Did you notice any other problems which came in conjuction with the alignment problem (e.g. speaker not working)?
.ox
Hi oxident
No, I don't have problem with speaker ( it was not working before but it is because of the jack plug problem - it solved ). Yeah, I did notice if I bend the screen carefully, the problem is gone. The funny thing is when I aligned the screen, it worked but if I closed it off and left it over night, it started again when I opened the lid.
You may right about the connector between LCD screen and mainboard. Well, I have no choice but openning the device and check it up.
Also, I read the thread somewhere in this forum and somebody advised this problem maybe relates to magnet around device. My brother aslo advised me that LCD charged and reserved negative electrons. Wierd but I am experiment it at the moment ( taking off battery and leave the device for a few days so that it can release the negative electrons ).
Hope it fixes
please help

8525 White Screen of Death - Is there Hope?

Ok so I have the fabled white screen issue on an 8525. When it first occurred I searched and read all the write ups, decided I had the ribbon cable issue. Took it apart and simply unplugged and replugged the ribbon cable with great results, no more white screen.
I repeated once when it came back after being bumped around, again with positive results...but this last(3rd)time instead of it working I now get white screen 95% of the time. I re-notched the sliders the first time, and last time.
During the 5% it works I noticed the charge light would correspond to it going white.This never happened before...
Example:
When OFF - Connect charger, Red light for 1 second, then nothing=White screen from power on
When OFF - Connect charger, Red light for 1 second, then orange charge indicator = normal startup
When ON and Working - Connect charger, no light, no charge - reboots to white screen
When ON and Working - Connect charger, orange charge indicator, reboots normally.
There is no heat or noticeable pressure on any parts, everything seems to fit normally.
It does boot normally with screen white.
Any ideas? I really don't want to give up on this thing, is there any hope? or just ebay it for parts?
Thanks
-Nick
same problems here, if someone could just tell me what parts to order, cause I have no warranty (ordered over ebay). I tried both the instruction that has chinese fonts on the page , and other from R&R, no luck, white screen all the way..
I had the WSOD and took it apart and reassembled a few time. The 3rd or 4th time the screem came back, but now it is shifter to the right around 1/4" or so. I mean there is just white along the left edge, then the normal screen/color starts and is cut off on the right.
Does anyone know how to correct that, is it related to the same flex cable or is there something else I disturbed?
mine will fade to white.. then i just push the power to put it in standby, then push power again to wake it back up and back to normal.. it rarely does it but still annoying...
If You Ordered From At&t
I had this problem about 2 weeks ago!!!!
I thought it was a fluke!
Anyway, walked over to 43rd and Lexington (NYC FOR THOSE WHO DON'T KNOW THAT MANHATTAN IS THE CENTER OF THE WORLD)
and they gave me the EXCHANGE HOTLINE for at&t.
I called them up, told them my screen is fading to WHITE and the lady sent me a new or referbished phone.. i dont even know.
Just so you know, i ordered my phone on AMAZON with a new activation. its covered under the MANUFACTURERS warentee for a full year from the date of purchase... so is the REPLACEMENT PHONE... but not from the date of replacement, just the date of purchase.
did anyone get deeper into this yet? I got a 8500 (need those without camera) from ebay USA, already with white screen. After reading here, that this is mostly an issue with connectors, I bought it, disassembled it and reassembled it, though still white. Should I give the contacts a treatment with contact-spray? (there's a tuner spray that doesn't leave residues) Or is there something broken within the ribbon cables? Seller said it has been dropped (but he also said, he didn't want to open it, while it clearly has been opened, one screw missing and warranty seal gone). It ssems to boot up normal otherwise, I hear a sound after the boot process, so probably this isn't a software issue?
Edit: another thing I noticed: When I run it without any keyboard connected at all, it's also white. I then connected the dpad again, and I could see a hint of the at&t logo in the lower part of the screen. When I pressed around on the back of the dpad a bit, all LEDs would go on/off... Sound to me like the dpad has gone bad, possible?
Edit II: Got it. Using a 20x eyeloupe I found that the PCB of the DPad is broken under the little chip on it. Now I just gotta find a dpad here in germany, but I assume those Hermes' are all equal...
hello
where can I get manual (if there is one) for disassembling hermes. link in wiki does not work.
thanks
this worked good for me

Anyone know if this applies to the 8125 as well? I've got a flickering white screen. I had dropped my phone a few weeks back and cracked the LCD. Replaced it with an OEM LCD - it worked fine for about 2 weeks and then just suddenly went all white. Phone still works, I can still get calls - just can't see who is calling.
I don't recall that the wizard had the same problem... Though from a logical point, it seems that there is an issue behind white screens and the thumbpad being responsible for it, so it may well be the same thing. Perhaps just disassemble the wizard (there should be a howto too) and check if theres a similar connection from mainboard to thumbpad circuit.
Is there a disassembling manual for a imate k-jam that anyone knows about?
Here's a website with a video manual i found useful...
http://viralelectronics.com/category/howto/page/2/
Figured out the problem...
The only reason I figured out the screen goes blank is because the motherboard loses connection with the screen when you slide the keyboard out...try this out and see if the screen comes back...
put the screen on sleep mode (no white screen)...then slide out the keyboard and tilt it a little hard after pressing on the screen and put the power on. if it doesnt work try again it might take some pressure and power to make it work...be careful not to put too much power but as far as I went, it's a very sturdy cell.
alternately, slide out the keyboard in sleep mode, and press all the buttons really hard and then try to press the power button (press more towards the space bar because that helps)...if any of this works and the screen comes back on even just for a second...follow the following
Go back to the person who gave the link to the site with opening the HTC instructions and follow through and clean the whole phone up from dirt around the screen and such...you dont need to put those rubber things or whatever it says to put on the screen...then when you are putting it back together, press hard on the wire connecting the touch screen to the motherboard. I suggest sealing it with a good tape...and then you are good to go! I did it but it had a few glitches...the screens contrast sometimes goes awry but it is still visible and responds to touch. Also, the physical buttons work as well!!
Good Luck and do it at your on risk.

i still have this problem.
fixed my wsod
I noticed a few days ago my 8525 screen went white, rebooted and it went away. Today it came back, but would only go away for a few seconds and then back to white. After reading some forums I decided to check the connector. I took the phone apart following this site as a guide. I removed the connector on the board side and cleaned the contacts with a qtip and denatured alcohol. Phone has been perfect for the last few hours, no more white screen of death. I didn't mess with the connector on the LCD side, just the board side. I'm a computer tech and I found it quite annoying to disassemble, but I managed without causing any damage, however, I'd rate the job at about a 8/10 as far as technical ability.

i agree that this is one of the first things to try in curing the white screen issue. Others may find their problem runs a little deeper and the contacts on the d/pad chip are broken. An improvised cure which may not be very permanent is to place a little padding on the surface of the chip as described here:
http://forum.xda-developers.com/showthread.php?t=321163
If you have appropriate heat gun equipment you can re-flow the solder on the d/pad daughter board - but remember to remove the sticky key pad layer or you'll cook it!!
I regret that I'm closing this thread because we have several "White Screen" threads and the questions and answers are being spread all over the place.

White screen?

I have an unlocked Cingluar 8525 (TyTn) I have had it for like 5 months now. Upgraded to WM6 as soon as I got in in July. Recently it has started slowing down and lagging a lot. So last night I restarted it cause it froze. When I did that it would freeze on the WM startup screen. So I rebooted while holding the 2 soft keys and then clicked yes to restore. That worked. Then today the phone fell off the arm rest of my couch onto carpet and I went to go send a message and it was all white. So I restarted and now everything is just a blank white screen, no startup logo or nothing. Has anyone had this problem before? I tried resetting it again and it didnt work. I have tried turning on with no sim card and same problem. Anyone know how to fix this?
It is all too common,
I've been told it is due to a loose connection between the ribbon that attaches the screen to the mother board.
I think its a design fault - the ribbon is linked to the two parts of the Hermes (screen and keyboard) and surely all that opening and closing is essentially moving something that is designed to be a static item. This I think weakens the ribbon connection, causing the white screen of death as I've nick named it.
Here is a link to dismantling the hermes to reconnect the ribbon.

Though you should know I attempted this tonight with very little success.
I still have the white screen issue. Its very frustrating that the reason I bought this phone (the slick keyboard action) is the reason I cant use it anymore.
Hope you have more luck that I did, Let me know...
PS - If you have never taken it apart before (I did to replace the screen) It should still be under warranty - or if yours is second hand - you could send it to apex laptops for repair.

[Q] Touchscreen Randomly Stopped Working

Ok, so first thing's first. I've been researching this for a few days now before creating this post. The touchscreen issues I'm finding online, are similar to what I'm experiencing, but the solutions have already been done, or my phone is not responding to them. I'm making this thread to see if anyone else has experienced the same issues or has any new news before I a) return my phone to stock, b) replace the digitizer, or c) buy a new one or upgrade to the G3.
My G2 was rooted, but kept on stock ROM with only small tweaks here and there. After the latest update, I noticed my work G2 had much better reception, so I returned my phone to stock to download the update. After updating, I re-rooted the phone, this time, the only thing I changed was the keyboard which I replaced with the G3 keyboard. Everything was fine for months until about a month ago.
It started with not being able to pull down the notification shade on the right half. No biggie, but after a week or so, it got worse. While using instagram, I noticed that the confirm button was sporadically responsive. Sometimes it worked fine, other times it didn't work at all. It began to progressively get worse on an almost daily basis. I decided to see what was going on and enabled both input options in the developer options menu. I found that the entire right side, about 1/8" was not responding to touch, the area not covered by glass screen protector( i removed it later while trying to troubleshoot). The upper right area showed about a half inch block that wasn't responding (the area where the data ribbon is). I was ok with that as instagram was really the only thing I used being affected.
About a week ago, the mid left screen area started being errratic. It began to get worse and started to affect the front touch screen buttons ( the area where the other data ribbon is). I enabled the input options again and saw that I now had a good portion of my left side of the screen was unresponsive. Even though I didn't drop it, I thought maybe the data ribbons had come loose as those 2 areas are where they are. I opened and disassembled the phone and re-sat the connctions after inspecting them. I double-checked all the other connections and LDIs in case humidity was the culprit. Everything looked good. Didn't fix the problem.
I've had to set my phone to unlock by facial recognition to ensure I don't get locked out, and changed my pin to use numbers not affected. I'm going to replace the digitizer, but wanted to see if anyone else had the same issue, or knew if it was, indeed, a software issue before I spend $75 (I will be replacing the digitizer and LCD to get it working sooner rather than risk damaging the LCD while replacing the digitizer and having to wait another week). I don't want to send it in to LG because I bought it on ebay and have no proof of purchase for warranty, and I want it working sooner.
One thing I noticed that may help with diagnosing, the screen now looks different when off. Before, in direct sunlight, you could see the dotted matrix from the digitizer, and that was it. Now, I can see the retangular pattern across the entire screen. I checked my work G2 which I just received a few months ago and the rectangular pattern is only visible on the edges of the screen, the center is black with only the dotted matrix visible. Keep in mind, this is in direct sunlight. In shade, the rectangles are visible on both.
I'm hoping it's a software issue, but I'm wondering if the digitizer is starting to separate from the LCD. I don't see any acutal separation though.
Thanks for reading the book, and for any feedback. Also, because it will probably come up, I want to avoid upgrading if I can because the G3 is just a little too big.
I restored the phone to stock with the most up to date software. Still doesn't work. It appears to be a hardware issue. I really thought it was software because the dead spots word for a split second after turning on the phone. Oh well. Guess I'm going to order a new digitizer or LCD combo.

Replacement screen bottom 1/4th of screen unresponsive. Need help!

Hey guys so earlier this year I dropped my phone and the screen cracked. I ordered an lcd + digitizer from ebay and installed it myself. Everything had been working fine for a couple weeks but then randomly one day I woke up and the bottom 1/4th of the screen didnt work. Also, my screen is not very secure onto the device. I can peel off the lcd if I desired. I put double sided tape on all the places that a guide showed me but the screen just doesn't seem to stay in which causes dust and other particles to get in between my screen. Could this be the problem?
Some things i forgot
This started off with only a small portion of the bottom part of my screen to stop working. But then it turned into my whole bottom 1/4th of the screen not working. However, the first time this happened, I fiddle with the screen since it comes off and just moved it around and the bottom 1/4th worked again. However the problem reoccurred and I can't seem to fix it this time.
Thanks for any help!
Edit: Forgot to mention that I tried to open the phone again and press down on the digitizer pins to make sure they were secure. Still didnt work
sorry for posing this as it offers no solution
but just to say i have the same situation on a nexus 5.. came compete with frame.. worked for a week then bottom 1/2 inch stopped working
My upper 1/4th of the screen stopped working... Seems to be like a fairly common issue with the LG G2 and some cases appeared all of a sudden without drops or water, some other with a bit of liquid or slight drop to the floor.
In my case I think it was due to excessive moisture when I used the phone while sweating profusely.
A screen replacement is at hand right after I get my smartwatch
