touch screen not working(intermitent) - Xperia Play Q&A, Help & Troubleshooting

Sometimes the touch screen does not respond to being touched. I discovered today that if i shake my play it makes a noise like something is lose and the screen works sometimes. If i keep shaking the play then the screen ussualy returns to normal then it will fail at sokme ramdom point. The game pad works flawlessly and has never failed me. I am assuming it is a flex cable. Does anyone know which cable I need and where is a good place to source it???
Thanks in advance
They better make a play 2!!!

anyone?

Digitizer

I'm no hardware expert but you may have just unplugged the digitizer, open it up and check, if not buy a new one

yea it souds like your flex is loose or dameged as the above poster said open your play and see.....and if its dameged then just go to ebay and look up a flex cable they are pretty cheep and buy it, then look up a install guide there are a few here on xda and bam see if that works

[Q] bizarre screen glitch

When closed my screen works just fine, and when I open for the keyboard it STILL works just fine, except that the whole screen shifts upward, so that part of the taskbar is actually off of the screen. If I open it slowly it seems like about at 10% open the screen flips horizontal, as it should, but then at about 80% of the way open the whole screen shifts upward until part of it is offscreen. Its not nonfunctional at all, but it is a nuisance, especially when playing any games I have the hardkeys setup as a controller. I've tried a full wipe and rom re-install and that didn't fix it. Also it seems like I've had to do a factory wipe more than once recently because the Home and Search touch areas have stopped working. Is there a weird software glitch going on or is my touchscreen on the way out?
I'm either going to just replace the screen for 35 bucks because its already kinda screwy, but if that won't also solve the weird screen shift issue ill just buy a new phone, any ideas?

Ok - so I think its hardware because the screen shifts even when the phones still booting. Would a new lcd fix this maybe?

I had the exact same problem. Your issue is in your ribbon cable, I was able to get my phone replaced but if that isn't an option for you, you can buy a ribbon cable and follow a very easy tutorial to install it

awesome, I've taken apart the phone a few times before, so now that I know the issue I can repair it finally! thank you so much for replying!! Which Ribbon cable are we talking about?
It is the ribbon cable that connects the screen to the keyboard through the z-hinge. I've never replaced it myself, but if your phone is completely normal closed and then distorts as it opens, then it definetely sounds like the ribbon cable has bad contact as it's stretched. It's really one of the only things it can be, if it were your lcd then the distortion would persist even in portait I would think

I must agree with the above poster, seems like its the ribbon too!

Back light not working on Xperia play, what do i need to change?

I just traded my mini pro for a Xperia play with no back light working and sd card not reading. Ive dismantled all of the play and put it all back together and still the same problem and i have also used SEUS to reflash the software and still no back-light. You can see the play is on, its just really hard to see and i can receive calls. Im hoping to fix this for my my girl friend as i already have one.
My main concern is the back light and then the sd i think lol also the green light comes on when charging
So do i need a new screen or can i just change a part?
Thanks
Is the screen light built in to the screen? Or could it be the proximity sensor is broke any one please
Also if I open the game pad a little bit the screen works and fully open didn't work.

Possibly a damaged ribbon cable?
That's what I think but the ribbon that connects to the screen and the keyboard is hard to get to, the only side I can get to is the side that connects to the keyboard, there's a video on YouTube but didn't show you how to take your digitizer or get the ribbon out completely.

The digitizer is not attached to the LCD and comes off with the frame. The cable goes under the LCD module and I've seen it for sale but I'm not sure if it's meant to detach from the other end. If it has a short or something, It's likely where it connects to the bottom half or where it folds anyway. Have you taken it apart and taken a look at the folding cable?
i also have the same problem.
my lcd light are off.
but my touchscreen(lcd) still working, i can make call receive call, open app and other.
but the light too dim. hardly to see anything that i click/touch on the lcd.
plssss help me out.
does i need to change the lcd? or other parts of the phone?
and where is the light on the lcd btw?
i already flash my phone. so i dont think it is software problem.
i have the same problem but have no light at all, screen self is responsive if im touching it but no backlight
please help
Solve myselft, my problem is hardware coz i flash my xperia play and it doesnt work either, so i send to shop to repair and it done, the prob could be ribbon n lcd, mine was ribbon

which cable do you mean? the flex cable that goes with the slide up and down or something else on the digitizer?
as an idiot i changed the lcd but of course nothing works.. still no backlight...

Weird flex cable issue?

I am having an issue with my touch screen where it will stop responding to touch I that I was beginning to think was my digitizer as it is cracked a little (but never had issues before after it cracked). Now I am thinking it may be an issue with the flex cable as when it stops responding I can side the game pad out which will bring up the game menu and I can use the touch screen again with it open and if I slowly close it I can user out like normal until it stops responding again. Does this make sense or does the flex cable have nothing to do with touch screen ability?

I saw a video on youtube where they dismantled a r800x and it seems like the flex has nothing to do with the digitizer... So try and change your digitizer... Now I'm not an expert is just what I saw on you tube

Screen randomly doesn't respond

Hi fellow PLAY owners, I'm having trouble with my screen. I can turn my phone off no problem, but when it comes to waking it up, either by pressing the power button or the home button, my screen won't turn on. I can slide it open, and i hear stuff going on as if my screen were on, but I can't see anything. It'll be like that for random amounts of time, like 1 minute, or as long as 5 minutes or more. Any ideas? THANks
That's the flexible cable problem...

I had the same problem..... and now it wont work at anytime... ); so am trying to replace the screen digitizer.
Alright, how about a little Xperia PLAY anatomy class lesson then? What does the flex cable do and what does the screen digitizer do?
they do different jobs

the digitizer lets the software know where you pressed on the screen, the ribbon connects the screen and digitizer to the main board of phone
So which one would it be if even pressing the power button, which is a harware button, doesn't respond?
Can anyone help me by giving me the part number I should order? I'm checking eBay but there's at least two options for the same named part... Thanks guys!
Is your phone underclocked while the screen is off?
Sent from my R800x using xda premium
mine has the same problem but i think there's only a dead spot. For example, the numpad place for 4, 5 and 6. Is there any way to solve this other than taking it to a technician? Problem appears at random times also. Thanks in advance!

I think this is a different issue. My entire screen won't turn on even though the phone itself is on.
By the way, my problem has gotten worse. Now it will only turn on (by chance) after I have slid out the gamepad. Grr..

As far as I know there is no under or overclocking going on. Not unless my ROM does it without me knowing it (Gin2Ics).
Anybody know the name for the flex cable part? Or the part number? Thanks/:cyclops:
So I bought this screen digitizer thinking that it was the problem... and it took forever to get delivered! anyways, I replaced the digitizer and am having the same problem.... :/ and after I changed the digitizer I noticed that the flex cable is actually ripped!! so now I purchased it from here and I'll keep u updated.
Hey thanks so much man. Hope it gets fixed. I want to know how it works for you so maybe I might do the same. It finally died out on me and screen won't turn on at all...
That's exactly what happened to me!
soo.. it finally worked after I changed the flex cable

That's cool man. Congratulations. I, unfortunately, didn't have the same luck. My phone is out for the count. I now have the sad news of no longer being an Xperia PLAY owner. Sad face.
I'll leave this question opened though, for others who might profit from it! :highfive:

[Q]What went wrong?

I have a huge problem, basically I was sick and tired of my black housing for the phone, so I ordered the white one from ebay. I was so happy it came that I forgot to shut down the phone, well during half way of the work, while I was trying to pry it open I remembered and turned it on and it worked I opened it a bit more open and it suddenly went black and since then everything is working except the LCD.
I have no idea whats the problem is the LCD broke or what?
Also when it shut down and me trying to reconnect the LCD flat cable to see if thats the problem I was nervous and did that which you see in the picture. Now my issue is what if I buy a new screen connect it and it doesn't work because the FPC connector?

The connection pins themselves do not look damaged, on the plastic shroud. The socket should work fine.
It's a little hard to make out fine detail in the pic...take a magnifying glass to it and check for cracks or splits in the pins.

Hmm it seems like it goes one small one then longer one, its hard to see from he picture but I think two of the longer ones are missing. And what should be the problem with the LCD because that happened before I damaged the socket.
Between thank you for the fast reply.

Well I don't see any missing pins, but you'll have a better view.
As for you LCD...no idea. Generally it's a good idea to turn everything off before you open electrical equipment. You could have caused a short in the process of opening it live.

Would that be on the motherboard or the LCD, basically should I bother repairing it or just sell it for spare parts thats my issue right now.

If you try to power it on does the vibrate activate...basically does it do everything you'd expect EXCEPT the screen doesn't work or does it do nothing at all?

Like I said earlier everything works, I can still receive SMS, phone calls (I can answer them since the digitizer works), e-mails, Facebook msgs, vibrations, sound, microphone... Everything works except the LCD.

You might try replacing the LCD and hope you haven't damaged the connector. If you have, a self-repair is unlikely given its size and that of the pins.
Or you dump it and buy a new phone.
Either way it's gonna cost you money. The first is cheaper but may not work.
I think that's your only options.
Yeah I knew from the start it was gonna cost me money, but I wanted the cheapest way out
Thanks a lot for the help I think I am gonna try to fix it. Get some experience while doing it too
