Xperia Play digitizer or flex cable problem? - Xperia Play Q&A, Help & Troubleshooting

Hi guys i have a problem
I can access different function through the MANUAL KEYS like settings, wireless , sound , display, and all the programs, but digitizer itself seems to be frozen.So i was wondering what is most common problem for that i presume flex cable or digitizer but digitizer is in good condition so what can it be ?
So cable 1 or 2?

Second one is analog touch cable.

To me digitizer doesnt work but analog works ?Which cable is that?

anyone?

whenever I slide out my gamepad my phone does not change the screen mode from portrait to landscape, neither does the xperia play launcher starts or the screen gets unlocked.
sometimes the screen automatically changes the screen mode from portrait to landscape as if the gamepad has been slid out when it isn't.
also games like PES 2012 don't detect the gamepad anymore used to work earlier.
what is the exact problem?
I asked a local mobile repair shop and he says strip of slider (flex cable) must be changed but it isn't available anywhere in my area. if this is correct then I may order the flex cable online.
what do you guys have to say?

To the OP:
My replacement glass+digitizer didn't have adhesive behind the connector like the original so every time the phone would take a hit the screen would go blank. I'd have to take it all apart and reseat the connector. Sometimes the cable that connects to it would twist out a little bit on its own during reassembly and I'd have to do it again. Not I use precisely cut tape or hot glue when I do one (careful of the slide rails). Though my problem usually manifested as a blank screen, twice it manifested as an unresponsive digitizer.
I'd check my connection first.

I responded to your PM. Yes, all the parts involved are available online. The slide board has two metal fingers inside a rail/slot that the bracket joining the two halves slides in. I don't know what the second one is for because all functions seem to react to the first one making or breaking a connection, but it could be causing the problem just as easily. These springy conductive fingers connect through the same flex cable as the switches that the face buttons press (Back, Home, Menu, Search) using some kind of conductive adhesive backing. That part is only a few bucks online, so it may be worth replacing just that to see. Unfortunately, the slider assembly is expensive (at least $20) but the slider + earpiece/camera + slide cable + switches is a comparative value at only a few bucks more.

Screen cable is seems to be broken

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

Touch screen stopped working

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).

Weird bug

very werid...
I did a lot of trial and test to make sure I can produce this bug every time.
I placed my Motorola Defy on top of my spare laptop that is covered by a thick cloth. When I picked up my phone to use it (the screen was already turned off) I pressed the power button and I noticed the screen was already unlocked.
After investigating what might have caused it I found out how the screen was unlocked. My spare laptop is Acer 8371. When the lid is closed the Acer badge (kind of big) is on the left bottom side of the laptop.
Here is the weird bug... if I place my Motorola Defy on top of the laptop where the acer badge is and the phone is positioned half way between the back cover's motorola logo and the locker then the car docker application would be launched which unlocks the phone. Then as soon as I pick up the phone the car docker application is inactivated (still running in the background) and the home screen is shown.
Once I made sure that I can reproduce this bug then the security vulnerability came in my mind. I did a basic test and it seemed as soon as you pick the phone up or try to use it the lock screen comes on.
After further investigation...
I initially assumed I need to tap the phone slightly over the Acer's badge to kick start the car docker application but I can confirm now as soon as I take my phone close to the Acer's badge and even still holding the phone in my hand the same thing happens.
In my earlier tests there was a thick cloth on top of the laptop and for my latest test I removed the thick cloth and managed to reproduce the bug far more quicker.
Whatever the Acer's badge is made of fooling Motorola Defy that the phone is being docked. Now that I have to keep my phone away from the acer's badge material I kind of relate to superman's misery when he was avoiding kryptonite.
And they all laugh at me for having a HP.
I wonder how many other people are having the same issue and with what models, if not all.
I just tried it on both HP laptops at my house only to feel like a fool when my wife looked over and asked if I took my meds.
Needless to say there was no bug on the HP side. I will have to test this out at school on a friends laptop.
Uh, dudes... that portion of the Defy screen responds to a magnet in the car cradle to activate the cardock app. Touch it with a magnet and you get the same thing.

Interesting finding. I just did a test with a USB cable (using the connector metal part) to see if the same part of the laptop that I previously reported is magnetic. Yes! it was magnetic indeed in particular at very bottom left corner of the lid close to the acer badge. Is that something to do with wireless reception wire?
Thank you for that. I can now be relaxed about it.
Also, if you reverse the polarity of the magnet you open a landscape "multi-media" station. Really a desk dock app.

Xperia Screen goes blank when closed

I just bought this Xperia, works 100% with the screen opened, I close it and screen cuts out, but is still running, and reopening screen stays off. Is this possibly just the cable betwwn top and bottom faulty?? Anyone had this before?

Yep, this has happened to me too. Its definitely the flex cable. The flex cable is the ribbon which connects the motherboard to the screen itself on the slider action. If you think you have warranty send it straight to warranty and they will probably repair it for you. If not, you can buy a full flex cable repair kit specifically tailored for Xperia Play on Amazon or Ebay. However, you do need some basic hardware knowledge to do this operation yourself.

[Q] What is the purpose of the front camera flex cable?

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...
