I broke the screen of my X Compact and replaced it myself. I used a replacement where screen and frame were already glued together. However, now the fingerprint reader is not working anymore. The phone seems like there is no fingerprint reader installed at all. The system (settings and diagnosis app) does not even give me the menus related to the fingerprint reader. Other apps also do not see it. The power button however works as expected. Therefore my questions to you fellow X Compact owners:
Did anyone else replace the screen successfully?
Or did anyone else have the same problem?
Did anyone replace the fingerprint reader successfully?
Thank you for your help!
P.S.: Besides this issue, the phone is very easy to open and to replace parts, except for the battery. Sony used very little glue, and many components can be replaced seperately. The only problem is that the battery is glued to the main board, which could be a problem when one eventually has to replace the battery...
You can still replace the battery fairly easily, though it is a bit hard to get off.
Did your replacement come with the button flex cable or did you use yours? The connectors and such are all well? This never happened to me on the z5c, which I think is very similar to the X compact. You didn't change anything in the software?

thank you for your answer! I kept the fingerprint reader, I just migrated it from the old frame to the new one. I kept all the flexcables too. The button itself is working, just the finger print part is not. The connector should be well, I re-opened it and checked. No software change.
Did you ever replace a fingerprint reader? Is there hardware verification?

Couple of days ago I received a new Qtek 9100 cover, and wanted to use that to replace my damaged T-Mobile MDA Vario cover. Got all tools at hand, so I started off disassembling the entire housing.
You really need to remove ->everything<- from the device in order to replace this front cover, so moved everything over to the new front-cover, and re-assembled everything.
Device boots up nice and smooth, though the touchscreen didn't seem to work. Hmm, that's odd... So, I disassembled everything again, checked whether the connection might be loose or anything, re-assembled again, and still no functioning touchscreen.
Now, I tried to use my keyboard, to see whether that worked. It seemed to work, though when tring to enter my SIM PIN, some of the keys didn't seem to work. I found out about 10 keys didn't work.
I decided to go back to the original front-cover, and voilá, the touchscreen worked again. The keyboard didn't though. Still about 10 keys not working.
Probably I damaged the Keyboard FPC cable, eventhough I can't see any damage to it.
Is there a way to fix this, or a way to obtain a new/working FPC?
The reason why the touchpad didn't work is probably because of the missing foam-strips surrounding the touchpad in the front-cover. Any idea where I can buy such thin foam-strips?
That's all for now I would have liked it to be a little easier changing covers, that's for sure.
No-one? I've tried several suplliers and repair-centers allready, but I guess I should harvest it from a broken one...
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.
While carrying a HEAVY 32" CRT TV my phone fell out of my pocket and I inadvertently stepped on it while wearing steel-toe work boots. The phone seemed to work even though the screen was cracked... I could get the comm manager up and push where I remembered the vibrate button to be and it seemed to work.
I put in a new LCD panel and all I got was a boot sound and a white screen, so I also tried a new flex cable with the same results. I also can't seem to get any kind of reaction out of it like before so I'm not really sure where to go next.
I'd really like to fix this thing but it's not worth putting an arm and a leg into it.
What do you guys think I should try? Anything I'm overlooking or something? Any help would be appreciated.
Thanks,
Noah

You need to be sure the new LCD is made by the same company as the old one. This is ESSENTIAL. See this thread:
http://forum.xda-developers.com/showthread.php?t=485961
In particular my post no 4.
Mike
Thanks for that tip, but both LCD panels seem identical except for the stickers, but the model numbers on the stickers are both the same. One has a larger print than the other. The number on both is TD028STEB1, and they both have a black ribbon cable.
Hmm. I just noticed. The old LCD panel says P/N 60H00037-01M and the new one says P/N 60H00037-00M. Even though these are both the Toppoly LCD panel could this mean they are incompatible?
Thanks,
Noah
Well, I think those two are compatible (bith Toppoly). So assuming the new one is ok as a replacment it leaves a couple of possibilities I think:
1
The connectors need to be re-checked.
OR
2
in the worst case scenario there is damaged to the d/pad board. A chip on the d/pad board is crucial for the functioning of the screen. Unfortunately this chip can be prone to micro fractures in the soldering between it and the board. (Even with normal button pressing many members have had a "white screen because of this cracking). Some members have found that putting a little padding on top of the chip to push it against the d/pad board can be used as a solution. (I think though, that this should be vied as a temporary solution).
Just my thoughts.

Hi,
i bought a factory refurbished I9600F from aliexpress. It worked great for 3 days, then the phone became slow to respond, the screen was flickering in yellow-green tones, and then wouldn't come back on but stay black. (but I would still get notification sounds for incoming messages, the notification LED was still working, and the menu keys also light up when I press home/power).
Pulling the battery fixed the issue once, but the problem came back after 1 hour.
I managed to revive the phone once more by pulling the battery and holding the power button to drain all remaining power in the device. The phone was working again for a few hours, but now it's back to having a black screen and even the power drain method doesn't work anymore...
So i'm guessing that replacing the screen won't fix the issue, since the screen is working just fine for a a while (both image and touch are perfect) - but then somehow there must be some electrical issue that causes the graphics unit to malfunction.
I checked the easily accessible connector to the left side of the battery, but it seems that the screen is mainly connected via flex cables that cannot be accessed unless you heat up your device and pry out the screen.
I have found some information on the internet that pressing hard on the spot where the flex cable connector is might fix the problem, but this didn't work for me.
FYI, I'm running the default Samsung firmware the device shipped with and used Kies + OTA update to get the latest official FW. No rooting or any other mods. Just some regular apps installed.
Any recommendation what I could try to fix this problem? Thank you all!!!
BTW, I have found similar reports on the internet here:
http://forums.androidcentral.com/samsung-galaxy-s5/405238-galaxy-s5-static-screen-won-t-turn.html
But the linked how-to-fix guide states that heating up the display assembly is only recommended on devices with a broken screen... So now I don't want to risk breaking my working screen.
So mainly my options are
a) open the device to check the flex cable connection
b) buy a new battery to see if that solves if (some people have reported success with a different battery)
c) buy a new screen assembly on aliexpress for around €135 and hope that a new screen will fix it...
Thoughts?

sorry, i actually never was able to get this resolved. I tried removing the screen to get to the flex cable, but broke the screen because I hadn't heated up the glue enough...
Had to buy another device.
Sorry I don't have better news...

I'm going find out the cause for this issue. I've disassembled one device that only lights up when it is warm. If I put it in the cooler it refuses to light up for some time after that. I tried placing only the screen in the cooler, also only the phone body in the cooler, but couldn't find any difference doing this as it refuses to light up both times for a couple of minutes then it works great again.
I've ordered another device that had its screen shattered so I will try my current screen on that device.
It could be some internal hardware fault in the mobo, it could be the LCD connector having a bad connection somehow, it could be the screen assembly itself, but I will find out eventually.
I've seen many places on the internet where people say this is a software issue. There is a very simple answer to that question. How could it be a software issue if not even the boot logo shows up when you start the phone?
I will keep this thread updated.
Verified that this is a problem with the motherboard. What circuit on the motherboard could have problems with cold temperatures? The main power one? If so, I will try replacing it with a different one.
Update: Was not able to fix it. Motherboard is now scrap.
Hi all. I replaced my battery, put the phone back together, and turned it on. Everything looked fine until I tried to use the touchscreen. It wouldn't register any touch. I figured I messed up the screen somehow when removing it, so I ordered a replacement screen - touch doesn't work with that either! Does anyone have a suggestion for what might be wrong?

Not to ask the stupid question...
Is the ribbon for the screen in the slot correctly? Seated all the way? Locked in place by that whatever the hell it is?
Thank you for your reply. Yes I have, it is screwed it and I've even tried pressing it down and touching it to see if it helps.

I have replaced the cracked screen on my PH-1 without issues... Since you are seeing the same problem with TWO different screens, I would check the connector on the board. Could be something like small piece of debris or dust or whatever. Remove the cable, and try inspecting it with a magnifying glass, if you can. Might be able to use a wooden toothpick to *carefully* clean it up, but I would only recommend that if you can actually see it well. You could also just blow a couple of shots of compressed air into it.
Other than that, I have no ideas, sorry...

might need a factory reset as this recilibrates the screen, back up ail your data first of course (pics, chats, game data etc). Not sure if recalibration apps still work, might be worth a shot first.
I had the same issue after replacing the screen. Someone on reddit mentioned the same problem and used a bit of foam behind the screen and its connection. I took a razor and trimmed a mm or two thick of some soft foam (used the foam that the screen was packaged in) and placed it over the connector. Touch was back after that, so it was an issue with the connection not being snug enough for me. Been over a month and everything is fine
