Hi
Some time ago i had custom rom on my Xperia Play, but flex cable from screen died and i replaced it.
After that, my phone freezed on Lupud kernel logo, vibrate and nothing more. No recovery etc.
Today i flashed it through flashtool to stock rom, and it started, logo "sony ericsson" pop up and after few minutes it dissapeared.
Now if i push power button i se some "snow, mozaic" on screen.
I don't really know what do next. I thought it's kernel compatibility problem, but know it look like damaged flex cable.
But kernel logo looks perfectly, only on rom something is broken.
I will appreciate any help.
IMHO, i think it's flex cable again.
I had also had similar problem.
1st and 2nd flex replacement went without problem
3rd was just black screen. It did vibrate, but nothing was on screen.
4th was half working (it show/stay on lupus logo and 1 in 10 tries it boot into rom but without touchscreen working)
5th was working on first try
It is hit&miss logic. Maybe it's problem with crappy quality, maybe it is problem with zif connectors on slider flex cable.
Try your flex cable again, but this time, first insert flex cable that goes from front camera/proximity sensor into zif connector of slider flex cable, and see how much actually is "good connection". Then press slider flex cable into possition and compare to your previous observation. If it's even 1/2 of mm away, it could be bad connection (flex from camera is not inserted fully in zif connector). Best position to be sure is that front camera flex have a very small "belly" (curved shape).
It looks like your 4th cable. I will try mounting it few times and order new one.
Now i realized, that "snow/mozaic" shows after screen shut down to save energy.
P.S.
For those from the future which will looking for solution for problem similar to mine.
Yes, it worked. Flex cable can work and don't in the same time.

Hello,
It seems that flat cable which connects the slide-out screen is broken: the touch-screen doesn't work, and there's a white lines all over the screen while opening the device.
I've made a call to my local service center and they said that I need to change the whole touch screen because the cable is glued to it.
Is it right? Is there another way to fix the device rather paying $300 for a new screen?
i have also the same problem For my PDA2K , my flat cable which is comming from the screen under the slider is broken ,, half of the cable , i have the orange cable ,, is there any way to fix it
Thanks
it just stopped working just like that...then i reflashed it n im stuck in the first screen where it says "tap to start" n i cant even tap now...anyone has any idea of how i can fix it at home...cuz its a lot of hassle to send it abroad...thank u
touch screen replacement
I had the same problem on my Universal and opened it to find out what happened.
I found the cable connecting the LCD and touch screen completely twisted.
Someone has played with it turning the screen in the same direction for many times without unscrewing it every time.
I manged to fix it partially soldering some wires that had gone loose.
Some wires were impossible to handle so I need a new wiring cable (it's a bunch of single ultra-tiny wires).
Now screen, mike and headpiece work again, but not the touch screen.
Do you have any idea if such a spare part can be found anywhere?
Possibly that would solve also your problem.
Who can have spare-parts?

Hmm....
Actually, not only the flex cable is originally twisted and looks funny out of the factory, you cannot turn the screen in the same direction more than it should be turned (e.g. from opened clamshell it only goes 180 degrees clockwise and cannot be turned anti-clockwise other than returning into its original position), it is stopped from turning by the way the hinge is designed. It is done specifically to prevent just the thing you described.
Generally even when some wires detach, the cable still performs fine, as the wires are not isolated and bunched together, as long as they do not detach from the connector itself. The fraying can happen when the flex cable is reinserted into the main case too roughly or one time too many, as the opening is fairly small and both cables need to be bent a certain way to fit through and pulled through in a particular sequence. Your problem could be caused by a faulty digitizer, it is connected to an LCD and if LCD performs fine, yet you lost sensitivity, the problem is not with your flex cable.
Cables can be purchased on Ebay. And so can digitizers (they are around $17-$20, but you need soldering to get them fitted to your LCD).
Recently, I disassembled my Sony Ericsson Xperia Play R800at. I was replacing the housing and digitizer. All went smoothly until I missed an important step. There was a black tab that holds down the flex cable that connects to the digitizer. I forgot that step and my flex cable ripped.I have ordered another as a replacement. I understand that this will cause the digitizer to not work, but I have more issues, and I want to know if they are due to the missing cable.(the ripped flex cable.) I assembled the phone and the screen functions normally. As to be expected, I can't interact with the screen. However, Now my search button and settings buttons aren't functioning. My home and back buttons are working although. Also, My phone will not charge anymore. Is this due to the missing flex cable? I hope I didn't accidentally screw anything up. I was really careful, so I don't know why they won't function. I really hope that these issues are due to the missing cable. :silly:
Sorry, I am not allowed to post links.It has the camera and earpiece on it and is attached to the slider. :"(
How. Could u miss a step itsm really easy to take apart and put together its the flex cable garunteed

Tutorials
Most of the tutorials seem to be only of disassembly. Little to none are of reassembly. I wrote down a list and reversed the order, but as it got closer to assembly, I started to assemble it myself. Big mistake. I assumed the black tab was only there to hide the chips.
Charge Recognition
It actually can charge, but only when the phone is powered of. This must be due to the missing components. Maybe because some parts of the phone aren't connected, the phone will not recognize the charger when powered on. What a relief...:angel:
Just watch dissassembly in reverse

I got the replacement part. I even replaced the slider. I transferred the button cable to the new slider along with the main flex cable and the camera/earpiece flex cable. I am confused. I am inserting the flex cable into the digitizer slot, but it isn't working. I assumed there was a lock mechanism of some sort, but still no luck. I am not sure why it isn't going all the way in. Reversing the steps just isn't working. Placing the flex cable in is way harder than taking it out. Is there a certain way to place this cable in. What I am in need of is a picture of how a functioning digitizer's attachments look. Are you supposed to be able to see the golden tip of the flex cable?(Again, I am speaking of the flex cable with the black tab covering it. It is very small.)
:crying:
Lock.
There were locks for just aboul all the ZIF Connectors. Sony Ericsson's manual is the best!:good:
I tried again using the locks on the slots but it still wont work. Even with the manual, no luck... Now, it is charging normally, even while on. This indicates that something has changed. I wonder why the digitizer isn't working though. Maybe I should see what happens If I revert back to my old digitizer...
So my xperia play had this fuzzy screen problem, after I bought the flex cable and replacing it I powered up the phone and seems it was working. Although the touch screen went completely unresponsive(buttons and gamepad work though). So what could possibly went wrong?
EDIT:Touch screen was working with the other flex cable.
Well this might seem like common sense but...maybe the new flex cable is also bad? I dunno :|. Did you try reusing the old cable to see if the touch screen worked again?

I might try putting the old one (with the fuzzy screen) again and hear if it does the unlock sound.
Will update with my findings.
i think youre moved tochscreen cable from it's place.
idk but can any one explain to me why does my xperia play flex cable damage so easily i don't even use the game pad cuz this is like the 3rd time i'm replacing the cable
well the 2nd time i replaced the hole middle slider with flex cable and other stuff already installed and nw that cable is broken

Maybe you slide the phone too fast or you push it too strong . My advice is you hold the screen while sliding it , gently and slowly . It may sound cheeky but ... I've been doing that since I first got my phone . And I never had any problem with the flex cable .
thats hw i always do it but i think that this cable damaged by the amount of sliding i did because i changed my digitizer as well (complete with sensors installed) and the proximity gave me some problems
so i had to slide up and dwn when calling to keep my screen alive
i think that damaged my brand new middle slide plate complete with all cables installed (including flex )
