Xperia Screen goes blank when closed - Xperia Play Q&A, Help & Troubleshooting

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.

Touch screen stopped working

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).

[Q]Xperia Play with a messed up(grey) screen.

Now I have tried looking up this problem, though not many results as I'm not really sure what I would exactly describe the happening of my screen besides grey. So forgive me if there has been questions like this already answered.
"Right now my Xperia Play screen is messed up screen. It started today when sliding the gamepad would freeze the system. Now, the screen is making this grey screen (pictures below) and freezes. Sliding out the gamepad and sliding it in seems to unfreeze it for a few seconds sometimes. Though, mostly, there's this. Is there any way I can maybe completely wipe my phone and reinstall Android? I have already flashed it once. Or is this a hardware issue and will I have to go to AT&T to see if I'm able to get a replacement phone?"
Like I said, I've already flashed it once. Did a Factory Reset before hand, though I didn't expect it'd do much. So any other solutions?
Maybe you should head to Sony Centre or AT&T to ask whether what's wrong with it. A reminder, unroot your device and get back to stock if you have custom rom and rooted your Play.
i think when you slid the gamepad it removed the cable connected to the screen. what was it called can't remember
I'm getting this a lot. I think there is a ribbon cable loose somewhere. I'll look into taking it apart sometime.
Same problem as my phone. The slider flex cable is the problem according to 4 old threads I found. If you're still under warranty, send it in. Otherwise, you can buy a new cable on Ebay like I'm doing, for 11 bucks and install it yourself.

The problem is the flex cable, as I have the same problem.
You can find a replacement cable here.

Xperia Play digitizer or flex cable problem?

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?
1.http://www.ebay.com/itm/SLIDE-SLIDE...246?pt=LH_DefaultDomain_0&hash=item1e708e88f6
2.http://www.ebay.com/itm/New-Replace...363534?pt=PDA_Accessories&hash=item1c299ee54e
I had damaged flex cable, and touch screen was still working, but screen was showing TV static all the time.

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.

[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...

I Can't Touch the Part of Screen Though Replace Digitizer.

When I disassembled my xperia play for the first time,
the screen digitizer was damaged by my mistake.
I can't sure that, but I guess it can be.
At that time,
the bottom of screen (about 1/3?) didn't work.
So I bought the screen digitizer,
and replace it today.
But the problem hasn't been solved all the way.
If separate into 6 parts the screen from top.
(For example the top part is 1st part.
And beneath 1st part is 2nd part.)
5th parts doesn't work.
But the bottom 6th part works well.
I don't want to buy else new screen digitizer.
Please let me know how to use my xperia play with any problems.
Please help me.
Thanks about reading my thread.

Are you sure it's digitizer problem? Maybe it's flex
I had similiar problem, but in my case whole touchscreen didn't work and it happened randomly on reboot
It turns out that when i was repairing my usb port i somehow didn't place flex cable properly and it was bended over that metal part of slider.
Once i reopen it (only the part with motherboard on it) and place flex cable properly, touchscreen started to work normaly
How old is your Play? When you opened it, does flex cable looks damaged?
Where did you buy your digitizer? If it was from eBay, you could ask for a replacement from the seller you bought it from.
Like Bakisha, it could be the flex cable. If you know the digitizer is working, it usually is the flex cable.

In fact, the flex cable of my xperia play looks a bit little.
The black color had been painted on cable wear a little.
So do you recommend me to replace flex cable?

If I ask for sending normal item without any problem again, should I send to seller the screen digitizer ?

Well, you could open your Play and see if flex cable properly placed. Open slider and put that white plastic inside metal frame. Put back dpad part of phone back, but keep an eye on that white plastic, it have two holes in motherboard to go into, then screw those two screws on motherboard (so it will make flex cable plug in motherboard - look if jack is now properly inserted
Close it and try it.
If you again have problems with touchscreen, then you have two options. Replace flex or replace digitizer. It's hard to say wich is faulty...
