Possible Ribbon Problems - XPERIA X1 Q&A, Help & Troubleshooting

My Xperia X1 is currently experiencing problems. The screen no longer lights up!
I started experiencing this problem a while ago, when opening and closing the device.
Day by day everything went from bad to worse and at one point it no longer lit up!
At first I thought there was some kind of screen problem so I bought one new LCD off ebay.
I disassembled my Xperia carefully following a tutorial on youtube.com and replaced the screen. Nothing changed. The screen didn't light up.
The strange thing is that everything else worked! Sound, buttons, vibration etc. all work without a glitch.
I had gave up my hopes of reviving my device and for four long months it simply got dusty. That is, until I found this post :
http://forum.xda-developers.com/showthread.php?t=561151
I opened my device and realised that I have the same problems mentioned in that post.
Thus, in an attempt to solve the issues I opened my phone and took the following pictures.
Please can anybody confirm that I have flex ribbon issues and tell me what I can do to solve this problem once and for all? Can I fix it or do I need a new Xperia flex ribbon?
I can't wait to start using my 'old' device again!

Look like a flex ribbon issue to me. You can fix it by getting a flex ribbon of course. I've had 3 go out on me...thinking about giving up on this phone entirely.

As mentioned in the previous thread re: similar problem, the flex will always be the culprit in any device with slide or flip form factor, not limited to Xperia. Most of the repairs coming in are for flex damage, regardless of the device price and quality.
I had no issues with replaced flexes on Xperia, once installed they serve their life span (albeit short one). It is possible to reinforce the flex, provided your tape is a very fine one, it needs to run in particular place only, e.g. where it is physically rubbed and bent the most.

Screen Problems - Possible ribbon cable loose?

Ok guys, need some help here....
Got a HTC TyTN II.... Worked great for like 8-10 months, then started having issues with the screen.
Sometimes when brining it out of sleep, the colors are all jagged, and the screen is out of sync and staticky (kind of when you have a VGA monitor and you half pull the cable out of the connector)...
So I'm assuming its a problem with the ribbon cable coming loose (if thats how its connected).
Another thing too, the memory card slot doesn't work anymore. This just re-inserts the fact the ribbon cable or whatever for the front of the device is loose.
Does ANYONE know how to fix this? Unfortunately I tried to rip the phone appart myself and voided the warranty...
Anyone else have these problems?
Sometimes the screen works, sometimes I have to put it back to sleep, wait 5 minutes, and wiggle the front. hit the power button and it works. This has happened across 3 firmware updates so it's hardware for sure....
It does sound like a piece of hardware is loose. The fact that your mem card is not working further suggests this. I took apart my Tilt yesterday to replace the screen which no longer responded to touch, although it still worked with hardkeys. As part of the process I noticed the mem card slot was integral to the screen components. In other words, the screen and attached component, including the mem card slot is loose. For video as to how to pull apart your phone, go here. I have never done this before and this video worked beautifully. Also, search the forums for the HTC Service Manual and go through this page by page, step by step matching it against this video (if yo have dual screens even better) and you will come out fine. I did!

You can buy replacement screens and the tools from the same website. Otherwise try eBay, which is what I did. Definitely get yourself a strong pry tool. The one I bought from eBay disintegrated in the first couple of minutes. Luckily there was just enough of tip of the pry tool for me to use brute force to pry open the case without damaging the phone.
thnx bud, ill be posting my results.

[Q] Milestone digitizer replaced, but new one has problem with "calibration"

[Q] Milestone digitizer replaced, but new one has problem with "calibration"
Hi!
I got a two year old Milestone on which the digitizer started to act up a while ago, with random clicks (seems to be referred to as "ghost" clicks) and touches everywhere, pretty unusable. After buying a new digitizer on ebay and replacing the old one, all those problems are now gone!
However, I do still have touch problems. It seems a few percent of the top and the bottom is unreachable. Input is registered, but at the wrong location. The bottom "buttons" (which is via digitizer as well?) works fine however!
A video of it says it all:
ht tp://ww w.youtube.com/watch?v=YNGcpAMPfUQ
(added some spaces to get around spam filter)
To me, this looks like some kind of calibration error... Not sure if that is applicable though.. Cannot find any kind of references to this on either this forum nor anywhere else.
Now, I've tried the following:
* Going back to stock firmware
* Clean CM7 (which is what I used before)
* Wiping all caches & resetting everything
Nothing seems to help. I can not find any calibration tools or anything either..
Any hints?
Thank you!

While waiting for a re-shipped item from the ebay seller (paid extra shipping only), the digitizer magically started to work again!
Not really sure how or why, but after leaving it powered up but idle for almost a week, the upper part of the digitizer was fully functional! The lower part was however still non-functional exactly like the video shows.
For some reason I got the idea that all this was somehow heat related; it had been lying in a relatively warm, closed off room during this period. So, I put the lower, still non-working, half of the digitizer (still powered on) a few centimeters below a regular desk lamp, applying some heat to it. I left it like this for an hour, and when I pulled it out, it was working flawlessly! Has now been working fine for ~2 weeks.
Just thought I'd post this here in case anyone else has the same problem.. There has to be some kind of manufacturing problem with this one, not being glued together properly or something.. At least I got an extra digitizer now as spare, in case this one gives up again

[Q] HTC one M7 Screen dead

​Hi there can anyone help me please on this matter.
My wife has a HTC One M7. last week the phone fell in to the bath. I managed to open the phone up and clean it.
The phone was taken apart and cleaned correctly using the correct circuit board cleaning solution (sorry cant remember the name).
I then ordered a new battery as the old one was not holding full charge. I also ordered a new screen + digitizer as the old one was cracked.
I have put everything together and charged the phone.
The phone charges correcrtly and has no problems at all.
When i switch on the phone it starts as normal and makes normal sounds etc BUT the screen is dead.
There is NO life in the screen at all even though its a new screen etc.
I know that the old screen is working and even using that i still get nothing.
Has anyone else come across this issue ?
Are there any guides to test the screen driver IC etc ....???
Thanks for your help in advance
It seems like that you have got a faulty screen.

MIght be a faulty screen as said above, maybe a broken or badly connected flex cable. And since the phone went into the bath, maybe a defective motherboard. Its very hard to tell.
as @alray said, it's hard to judge what's the cause of the dead screen, it may be one of the three causes.
so first, you can connect your old screen to the motherboard, if it can still work, to check whether the mother board was damaged or not
if the old screen can be lighten up, you can exclude the possibility of damaged motherboard.
second , you can connect your new screen to the motherboard again. Just be carefully and pay attention to the connector. Make sure it is connected correctly. If the screen can't be lighted up, you need try to use achohol or something else in a small brush to clean the connector. Handle gently to avoid damaging the IC. After that check whether the IC has lost some part or not. Then, if the flex cable or connector is fine, you can connect the new screen to the motherboard again.
finally, if the new screen still keep the same same situation. you can almost judge that you ordered a defective part.
May the steps above helps!
Hi there
the screen works fine as well as the connectors.
These have been tested on another htc one phone.
I have noticed that the motherboard connecter is damaged..... i will try to get some pics up later today.
Thanks

[Q] Replaced Back Panel Glass Now Won't Boot???

Hello guys long time member never posted much, I've used the forums to root/unlock/install custom roms with no issues since I've had the phone.
The problem I'm facing is I've recently replaced a cracked and broken back panel, but now my phone won't boot unless connected to a charger. I have had zero problems with the phone aside from some overheating here and there, I'm wondering if maybe I heated up the battery too much and killed it or maybe I accidentally heated up a part inside the phone it's self. I've searched all over the forums and on google and can't find anything pertaining to battery or phone damage while replacing the panel, so I'm hoping someone here can shed some much needed light on the issue.
If it's of any relevance I was running 12.1 yuga candy 5 rom when I did it and it was running fine aside from an annoying rebooting and optimizing apps bug.
There is no water damage anywhere on the phone except for in the headphone jack which happened shortly after I got the phone over a year ago.
One more small detail, after I pulled off the broken panel there was a tiny screw that was undone and stuck to the adhesive tape, it came from underneath the camera lens on the left side. I was confused as to how it would have unscrewed it's self like that but I did put it back in, could it be that the screw wasn't meant to be there in the first place but they left it inside the phone due to laziness?
Hoping for some feedback or some type of help thank you greatly in advance to anyone.
Edit----
The phone is now on but turns off when disconnected from the charger, but it does show that the battery is taking the charge, what the heck could this mean?

Touchscreen malfunctioning.

Hello,
I bought a used Z1 almost a year ago. Everything was working perfectly, I was very content with my purchase but I broke the display shortly after. I got it changed at a local repairman but ever since then, my screen acts weirdly.
1. When I use the phone for 10-15minutes, it gets a little warm and so do my fingers and then the touchscreen starts acting weird and pressing stuff on its own. If I lock/unlock it, the problem is solved.
2. Same thing happens when the phone is turned sideways for a few minutes and when I flip it vertically, the touchscreen starts acting weird. Lock/unlock fixes the issue again.
The fact that lock/unlock fixes it leads me to believe that it's not a hardware problem. I started a research and found this topic - https://forum.xda-developers.com/showthread.php?t=2691849 , however it's a bit outdated and is already edited saying not to try the fix. I'm not proficient enough at this so I cannot really grasp the idea behind the topic mentioned earlier and can't get myself to try it cause it might brick my phone or something.
Any suggestions would be helpful.
Regards:good:
sorry to say you friend but it's a hardware problem it's something related whut the screen contrast I've tried everything the only thing left it's to get an original screen replacement and I haven't been able to get one in my country
Generic Screen, that's the problem, i would never recommend to buy a "new" screen, always buy an used one or a phone with broken motherboard and swap them imo
tbh, your problem is weird to, may be a bad installation, i had the same problem in a z1 that i use for games, disassembly all the phone and now I'm using the screen without gluing to the base and the problem was "solved"
