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.
Do I blame the onboard video or the LCD itself for this problem? I've taken the phone apart and re-seated the motherboard connections, which was no help. If I connect using EveryWAN the phone appears to be working fine, in fact I flashed the T-Mobile ROM and than the Button ROM thinking it was a IPL/SPL issue. Even if I try to start in boot loader mode the screen still looks the same.
Just trying to decide If I need to replace the motherboard or the LCD.
Thanks,

Screen seems intact without any damage visible, no cracks or out?
Had this problem once with my old Universal, was the colour transfer wires that were loose, but pretty sure the Uni is totally different to our wizards.
Prehaps open her up and see if theres anything thats loose prehaps.
I had it opened and re-seated both the connecting cables, but no luck.
Ive had this problem with my wizard .. i couldnt find a solution. tho i didnt really try very hard. Basicaly just picked up another one on ebay for like £30 seemed cheaper than spending the time and effort fixing it. I think mine got progressivly worse. It used to do it occasionaly and now just it as soon as its switched on
i have a same sort of problem...
left of the screen fills with lines and the whole screen fades to white.
turning on and of the screen via power button takes it back to normal but then it happens again.
noticed it only happen in portrait so i have to set it to landscape all the time
for some rom and spl's it happens just a few times a day and others i cant use it in portrait.
If i find a solution it might be working for you to
Fading white screen of death
Could be the battery. Have you tried a new battery?
Solved.
The LCD itself was bad.
Hi, I come on here quite a lot for information as it's an amazing resource! This time however, I'm attempting to give something back!
I experienced the "black screen on slide out" on Monday. Phone completely screwed. I've also had a few droppages and had it apart once before so there's no way warranty is gonna help!
I stripped it down and soon discovered what it is that actually fails on the ribbon. The coating had worn through due to rubbing on something during the slide out / in process. it had been playing up for a while, probably due to shorting out on the metal case, but now the tracks (aluminium?) had worn right down.....
In pic 1 i've circled the worn area. The shiny section is where i'd tried taping over it to prevent shorting, before i realised the tracks were gone.
Got an almost new one off ebay for 15 quid and, realising it was going to happen again, came up with a solution that, so far, looks like it will work....
A while back I bought some "anti rattle felt" for my car's dashboard - really thin and strong self adhesive felt to prevent squeaking joins between dash sections. I cut a piece of this and stuck it to the new ribbon. Once this stuff is on it's well stuck, by the way!
See pic 2 for the modded ribbon cable.
On reassembly everything is working just fine so far! Here's hoping that it lasts longer than 6 months this time!
Just need a new casing now as mine is decidedly second hand!
Hope this turns out to be of use to someone!
cool story bro
when i took apart my xperia to replace the housing this seemed like a really weak point in the device. glad to see someone who has had the problem has been able to fix it
Why does the screen go black?
Hi,
When the coating wears off the ribbon cable it exposes the tracks in it. when you slide the keyboard out the exposed tracks short out on the metal casing and the screen loses it's input signal.
thats whats happened on mine at least and i presume quite a few others?
HTH!
Update:
That's interesting: My phone was also losing signal with the keyboard out, and occasionally while closed up as well. It would just randomly drop to "no signal" for a few seconds.
It hasn't done it since replacing the ribbon cable.....could be coincidental of course.
I'm having the same problem
It just started a week ago and I got the phone in January off of ebay. I'm new to opening up the phone so could anyone help me find the correct tools or have a link to a site with pictured instructions?
I noticed that the sliding mechanism started to go loose about 4-5 months ago but didn't expect the screen not respond in landscape mode. I have yet to see the other symptoms you all are referring to. I would like to fix this before it get worse.
In mine case it went totaly black after one week of this problem... You have all the instruction on youtube, there is where i looked. For tools you can be inovative, but the exactly right ones come with housings from ebay, it is only 15EUR, and i bet you have some cracks so it wouldn't hurt replacing. That is what i did, along with ordering new sliding mechanizm, and new ribbon cable.
I am open for ideas to prevent my ribbon cable from being cut at it weakest point again.
I'm assuming my flex ribbon went bad yesterday, since sliding the keypad out causes my screen to shut off.
Already ordered a cable off ebay and will attempt to replace it myself :O
Replaced my flex ribbon cable with one I bought on eBay. The screen doesn't turn on at all now, which leads me to believe the cable I was sent is defective. Put the old one back in and it works okay, less landscape mode. ughhh what a pain.
great tips! my input is I bought a case off of ebay that was ~60$ and everything actually fit fine for me...so I wouldn't discount every seller but you do get what you pay for, the 15$ cases are probablly the ones that will give you problems
I working in a mobilephone repair center if anyone need help drop me a priv... i able to get 2nd hand or even brand new components
Replaced the flex ribbon cable -
I got my flex ribbon cable a few weeks ago and took it to my local repair shop. They replaced it but the LCD screen/optical joystick receives no power. The touchscreen and everything else on the phone works just fine now. I thought it was a defective item so it was exchanged with a new one.
Got the repair shop to replace it again and the outcome still remains the same as the first.
Theres no light coming from the screen nor the side illumination.
I just told the repair shop to just place the original back in for the mean time.
Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power botton.
Could it be defective a batch that the seller was sending out? or the repair shop's mistake and is playing dumb so they do not have to admint fault?
Hopefully there's an easy fix to this problem.
-Also I did inspect the ribbon before and after the repair. looks new as the OEm
Can anybody help me out with this new problem after replacing the cable -
perhaps you should try a hard reset. Ive had problems in the past where the optical joystick and the illuminators did not work, and that worked for me.
On the other hand, the top illuminators are on the same piece of hardware as the flex cable that was replaced, so a faulty flex cable is possible. The bottom illuminators are on the circuit board that the optical joystick attaches to, separate but connected to the flex cable.
Ive recently replaced my flex cable and touchscreen. The experience i had with the faulty touch screen was that it appeared to receive no power, but was in fact displaying a dark backlit illumination that could only be seen in the dark. At the same time however, the screen did not display anything. I'm not sure if this is similar to your experience, but if so then your touchscreen would need to be replaced.
ive done all repairs on the xperia myself, and one thing ive discovered is if something doesnt work right after a repair, simply disassembling it and reassembling it to make sure all the connections are properly done has worked for me in the past.
"Before the repairs, there would be a flicker of white light and random illuminations. Now there's no lights at all except the power button."
Now when you say the power button, do you mean that a red light appears under it?
I dont know if i can come to a conclusion or that i can help (or have helped) you come to a conclusion, but i can only assure you that the xperia acts out in strange and weird ways.
Good Luck!

Thanks for the links. I've tried the hardreset and restoring the original rom but the issue is still there. It's really bugging me that everything works but the LCD screen. I'm currently using MyMobiler to use my phone. The touch screen works fine and so does the soft keys. Just no power for the lights. I might just give up and wait for another phone that catches my eye and then tinker with the xperia myself. but if anyone got a solution or want me to test something then I'll give it a try.
My warranty is no longer affective so I'll use my phone as a tester to help others with any problems.
TRIONDAVE, how's your Xperia running now with the cable mod that you did? Its been 6 months since you created the thread. I hope you're still around.
My Xperia X1 works nearly fine, except for the keyboard issues, so I'm thinking of opening it up. If your Ribbon mod helped I might just do it too once I've got it opened. Mine has a MOUNTain of cracks though, and the battery compartment itself is cracked on both side enough to make the compartment CURVED. Hence the Battery cover doesn't sit well.
I'm looking around for broken Xperias which I might be able to use to change the internal cracked casing. Lets see.

My thoughts exactly.
Hello guys, I am in need of real help over here!
Its just that Ive replaced my ribbon cable, the old one got screwd up.
However I got done for 10 minutes ago, tried to start up the phone.. without success :,(
The ribbon cable doesnt have anything to do with the start up, only the screen am I correct? Cause I cannot even start my phone..
Ive connected the charger, but when I remove the battery it shows a red light, meaning no battery, correct?
So what may the problem be exactly? Maybe the battery is all dead, or?
PLEASE HELP!
for the people with ribbon failures how long have you had the phone before it occurred ? im just interested on the cables lifespan.
mine is fine so far but i have noticed the slider is flimsy and rocks left and right.
Guys I did some search job today and have a possible final solution to the back button problem.
Luckily this is also in the forum posted by user ID:insaneturbo13
his thread is here:
http://forum.xda-developers.com/showthread.php?t=833663
He is a Samsung Captivate user, right. Since I think if nexus s have met with is annoying problem, other samsung phones may either. So I did some search job in bed with my insensitive-back-button Nexus S, and found the Epic 4G, Samsung Focus, Captivate, etc. Almost all samsung phones got users annoyed by the problem.
Then I searched the Youtube to see if there is any Samsung user had ever achieved some success in solving the issue, and I found.(You won't know how terrible it is when you have to use a U.S VPN just to watch Youtube since it is blocked in here China mainland... really slow speed...together with facebook and twitter...ToT)
My understanding to the cause is: The picture of the back button is a thin line with an arrow, so the inside paint here may over-cover this thin line, which will definitely make the touch action less sensitive. And that's why there are less people got such problem with the other three keys.
And since capacitive buttons actually respond with the obvious temperature difference, so many frustrated nexus s users like me found under warmer environment the problem is less annoying...
Maybe this is only workable for insensitive problem. But hopefully this is a way.
Since I am a Chinese, it's impossible for me to have an exchange with the Bestbuy. So this is my only solution. But for most of you, it's highly recommended to take several exchanges before you definitely want to try this way.
Of course, try this at your own risk
what i did was tighten up the screws on the back of the phone... especially in the lower part of the phone. I haven't seen the issue since and initially it was a pretty often issue for me.

I think this is also a good way to solve the problem especially when you dont have to take to phone apart~
The theory may be the same, which is to make the distance between your touch and the module inside shorter cuz there is a piece of rubber under the button position so it can be possible~~
Thanks for sharing this way Dude~~~

how did you access the screws at the bottom to tighten them?
Take off the battery cover. You have 6 bright screws around the edges of the phone. Tighten those up.
Sent from my Nexus S using XDA App
Although, I know this is not gonna help, but it comes from personal experience.
In the beginning, I used to be haunted by the silly back button "bizarre".
I factory reset the phone then voila. It's gone.
The reason I am confident to post this is, my brother's phone was fixed in
a same way as well. I know, I can be just lucky, but I just wanted to share.

thanks, I decided to watch the video on how to take apart the phone this morning, didn't do it, but it covered the screw access for the hidden 2 screws.
tightened the screws what little bit I could without fear of breaking something (they were already pretty tight), but it made no noticable difference.
I actually got my phone a few days before they were launched (friend is at&t store manager), so I 've been living with it as long as they have been available. it's annoying, and did get a little better with froyo, but not bad enough for me to tear apart the phone and risk damage to the screen...

there are no hidden or covered screws and the phone doesn't need to be taken apart.
look here: http://guide-images.ifixit.net/igi/BJtxWYS4NMaMyMKL.medium
these are the 6 screws
Mine just started this thing where it presses the back button by itself. Pretty anoying and is making the phone useless. I can't do anything without it just hammering on the back button.
hi everyone,
i'm new to this forum, and joined to see if anyone has been successful in fixing the back button issue...
i've followed some of the advice from previous posts (tightening screws, reset factory settings, updating the OS) but still no luck.
hoping that someone might have discovered a fix (apart from returing the device!) they could share.
thanks!
-----------------------------------------------------------------------------------------------------------
hi everyone,
After posting the thread above, I updated OS to 2.3.3 and now back button is working fine.... I waited for a couple of weeks before confirming this, so hopefully anyone still waiting on a fix could try what I did. This seems to be a software problem more than anything else...
btw - 2.3.3 noticeably washes out colours, and there's a yellow/green tinge to white space. awful.

Hi
I did the same and the problem has gone - just realised after reading your post that factory reset solved this problem.
My phone is constantly on 3G but whenever it dips into Edge or has a weak data signal I notice the back button issue as well. And I tried a factory reset but it did
not fix the problem on 2.3.3
Back button issue
There are a few longer threads in this forum about the back button issue on the Nexus S -- for some people the back button doesn't work at all, and for others it turns on all by itself. There were a few replies from a Google employee (ryguy) who said it would be fixed in an upcoming OTA update, etc. but some reported having problems AFTER getting 2.3.2 when the problem didn't exist before. There are also other reports of tightening the screws on the back of the phone, which haven't tried but seemed to improve things for people whose back button WASN'T working at all.
For my phone around 2-3 weeks after buying it I had the back button come on all by itself. I fixed it by doing hard resets, as suggested on an earlier thread that deals with this issue (it's like 10 pages long but has the complete story of everyone's experience and fixes with this issue). Anyway, the point is for me after the first hard reset the problem persisted, so I did it a few more times (like maybe 5 times) and now it's gone.
There are some people who tried a hard reset (factory settings restore) and the problem still persists but I think that you have to do as many hard resets as possible (like, over and over and over) until the problem disappears. I'm rooted so I did a Nandroid backup first, then did 5 hard resets through Clockwork Recovery (select the "Wipe User Data" option), and after five hard resets I just flashed by backup and I was back to where I was, minus the back button issue. You don't have to be rooted, of course, to do this, but if you are, doing that ROM Manager backup allows you to quickly reinstall everything to the exact way it was after you're done with the five or 10 hard resets or whatever.
If you're unrooted you can power off the phone, then turn it on while holding the Up Volume button. This boots you into Bootloader mode and you can navigate around to do a factory reset. Or, if you are rooted and have ROM manager, you can use ClockworkMod Recovery like I did (see other threads on how to use these programs).
Anyway, again for me I had to do a bunch of these hard resets to fix the problem, so if it persists after the first two resets, I think you have to keep doing it until it disappears. Hope this helps - TC

i think mine is forever beat. 15 hard resets and its still there.
My apologies for bumping such an old thread... But i got a captivate to serve as a backup phone, and i slapped over ICS on to it..
Everything was super awesome.... BUT! not the Back button.
A few minutes of google'ing later, im here.
So after reading through this thread, and the one linked to in the OP, i opened up my Phone and ....well....went on with it.
50 Minutes later :

Some Tips :
1: Once your down to the frame with the LCD assembly stuck to it, first remove the Antenna Module. Under that disconnect the black ribbon connector. (This ribbon connects the capacitive button module to the main board).
2: Before starting to Pry apart the LCD from the frame, take a hair dryer and heat up the edges of the LCD Assembly's frame. This helps a freaking lot in prying it apart. Plus it somewhat preserves the 3M adhesive tape present underneath, and can easily be reused.
3: Start prying open the LCD, from the Ear piece side. Take your time and DO NOT!! And i freaking mean, DO NOT!!!!! rush through while removing the LCD assembly.
4: When your almost half way through (or slightly more , but significantly above the capacitive buttons) take a peak between the frame and the LCD assembly, youll see the "Bridging/Connecting" ribbon i mentioned earlier and it might be stuck to the LCD's back.
-> the best way to proceed further is to simultaneously heat up the "glued" parts and slowly continue with removing the LCD. This way, the glue will not stick to the whatever parts it is meant to stick to , THAT strongly and will be much easier to remove.
5: Now as soon as you reach the part where you can see the Capacitive button module sticking to the LCD assembly, go into SUPER FREAKING SLOW mode... THE RIBBON UNDERNEATH IS VERY VERY FRAGILE! ONE YANK AND YOU'LL HAVE TO PURCHASE A NEW CAPACITIVE MODULE.
*Best way to do this is, to again simultaneously heat the concerned parts while slowing pulling the LCD assembly and the capacitive button module apart.*
You can try going LEFT-RIGHT-LEFT-RIGHT alternatively, to slowly make the adhesive give away.
6: After you have the LCD assembly out, its pretty much dependent on how stable yours hands are at slowly etching out the Light gray parts.
-> You can hold the LCD assembly against a TABLE LAMP / some light source, to better see which parts of paint you need to etch out. *i Almost etched the whole of my back button* So be very careful and gentle as well PATIENT!
Before assembling the LCD back into the frame, i took a small piece of paper (about the size of the capacitive button module) and stuck it between the frame and the module. Just so that it makes better contact with the LCD assembly.
7: Stick the LCD back onto the frame and again heat up the edges. Also while putting the LCD back together, make sure the adhesive tape has not lumped up on any of the edges (This might have happened while trying to pry the LCD out) , if it has, then just gently even/flatten it out. Stick the LCD back and heat the edges. Rest, just take a soft cloth and squeeze the LCD's edges and frame together,so as to make sure they stick together properly. The heat really helps in bonding things here.
Assemble back the phone, blah blah.
I used a CREDIT CARD to start prying the LCD away from the frame. It was pretty easy, because of the heat.
DO THIS AT YOUR OWN RISK! I AM NOT RESPONSIBLE IF YOU SOMEHOW MANGE TO MESS UP YOUR PHONE! Specifically the LCD and the CAPACITVE TOUCH MODULE!
Big thanks to the OP for posting this.
Hi,
I own an Oneplus 2 for over a year now, in which I had to replace it's display two times . The first time I ordered a new display+digitizer assembly and replaced it myself, went great and everything worked fine. The second time was a month ago, I ordered the exact same display from the exact same seller on Ebay and did the replacement. I tested the display before assembling the Phone and it worked as it should. But an hour later when the phone was already assembled I discovered that the touch screen was completely unresponsive
After some trial and error I came to this conclusion:
the problem seems to be caused by applying a mild pressure anywhere on the bottom right quarter of the screen
the display does always respond when I hold my finger on it (with or without applying pressure) for about 4 seconds, then it sees my finger and I can swipe around (while still holding it down)
if I try the method above a few times, or let the phone rest on a desk for some time, the problem disappears and the touch screen works fine again.
So far, it looks like a hardware-issue, maybe a faulty screen or I messed something up while replacing it. But it gets weirder:
My OP2 is rooted and at the moment of replacement, it was running Lineage OS 14.1 (nightly, 2017-03-30). And when I wanted to update that to it's newest build, I realized that this whole touch screen problem doesn't exist in the TWRP recovery interface. It worked perfectly fine even when I tried to recreate the problem by applying firm pressures on every spot on the screen. So this made it look more like a software-issue, however the update of Lineage didn't resolve it and even restoring my backup of OxygenOS 3.5.6 didn't help.
I found this XDA-post about having firmware issues for the touchscreen with Android 7, but running their fix did not resolve anything either.
Right now my phone is pretty unusable since having it in my pocket is creating the problem. :crying:
Does anyone have any ideas of what the exact problem could be? Or anyone having similar issues? Why is it that there is no problem at all when booting into recovery (TWRP)?
It looks like loose connections between the display and digitizer.
After all it was a hardware issue. I disambled the phone again and after a lot of trial and error I found that there was something that came in contact with the back of the lcd that must have created a short cicuit or something. I placed a thin sheet of paper on the back of the lcd to prevent this and it all worked again! Still weird though that it didn't happen in TWRP.
