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
Sent from my R800i using xda app-developers app
which cable?
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...

hey guys yestrerday my phone took a path for the worst
i was mad at something and so i banged my phone against the table *anger issues.Now the phone turns on but its all black screen and sometimes partially gray and partially black. I can hear the volume when i press it and the phone vibrates and rings for calls but i cant see nothing its all dark.
i assume its not a software problem...rather hardware. Did i break the screen or disconnect a ribbon from the board to the screen
i have a G2 obviously with ics
more than likely one of those options. may be hard to diagnose it until you open it up.
even then it may not be obvious if its the screen or flex cable, but im guessing its one of them.
good luck!
I opened it and found out that all the plugs/ribbons are connected.
I think the ribbon cable can have wires that are severed inside, despite the shielding still being intact.
Can it be possible that the screen is broken becuase only the screen is black i can play music because i remember where i put the widget.....so can it be the screen because i dont think its a ribbon
Both the lcd and ribbion can have the same effect. I can't tell you which one is bad on your end, but I can say that with all my years fixing slider phones it almost never is the lcd

So what ur saying is its not the screen
Can it still be the screen although i took it out and it dosent look broken, take a look:
Not saying it isn't the screen I'm just saying that it more than likley is the flex cable, harder to replace and about 35 usd vrs 20 for an lcd. Take your pick but if it were me id go flex cable

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?
Sent from my R800x using XDA
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

Hi friends, from last week am facing a display issue in my desire z mobile. The display changes the colors when ever i unmask the KB or sometimes even when it masked... when i googled for this problem i came to know that the ribbon cable is loose. so i decided to open the mobile and reconnect the cable. I did everything perfectly, but when i repaired and turned on the mobile , the screen is black.. only after rebooting (by hearing the welcome tone) my menu keys start lighting and by pressing the power key my screen turns on. Even i cant see the boot loader page ..
I think this could be a software issue, but i dont know how operating with the hardware can mess up the software
Friends please guide me
Something is up with the ribbon cable either it came loose again when u were putting back together or its broken.
I actually fixed mine today, it was wearing through the black outer part and was making the screen jump during scrolling and long pressing when only tapping.
I fixed it with a small piece of electrical tape placed over the exposed part. I guess it grounds out once it becomes exposed.
U only have to remove the mother board from the phone to really see most of it.
What exactly did u do? Is there an exposed part of the ribbon from wear and tear?

U should get a q tip with some rubbing alcohol and clean up the connection and blow on the connection to make sure there is nothing there. Just take our time when u do it u don't wanna mess anything up

sorry i cant get your way of cleaning the connectors. could you please elaborate me the cleaning process? Then bro, still i dont know why i was not able to see the bootloader screen and the bootup animation... but after booting up mobile works fine... so confused
Sorry use a cotton swap dipped in the alcohol to clean the connector on the cable and mother board.
Does the phone have a custom recovery? If so what happens when u boot into it?

no it doesnt have any custom recovery. first i come across the screen colour fault, so i rerooted my phone to claim warranty, but unfortunatly i was not able to claim the warranty. so i felt to open the mobile myself and tight the ribbon. After attempting this repair now new problem araised ie i cant even see the bootloader page and boot animation.. but the phone is working fine..
whenever i turn on the mobile the black screen remains , then i will here boot tone then my soft key lights will lighten, then i will press power butto, then my lock screen will pop up. this is my situation.
Dont know what to do
First let me try your cleaning option, but could you advice me something other than the alcohol ?
Alcohol is the best cuz its sterilizes and dries fast. U don't need to soak it just to get the cotton swab wet and shake off excess and dab it on the connections. If u rub it might get cotton stuck. U could also use a keyboard dust blaster or some kind of compressed air to blast away any particles.
The main thing is to make sure u connectors are down all the way and not to have any tension while putting it back together.
If u separate both halves of the phone make sure u connect to the back of the motherboard after u have tightened down the brackets that keep the two pieces together.
Are u trying to avoid having to remove the sticker while loosening the motherboard?

Now the problem getting worse.. after a cleanup with a cotton bud, my touch sensitive fails to work.

dont know what to do. Its just a 3 month mobile, cant lose it
Ur doing something wrong all ur problems has to do with the cable. That cable connects the screen to the motherboard
Sent from my GT-P3110 using xda app-developers app
I think the proper response is replace the flex cable, they do go bad and for the most part I'm sure you didn't do anything wrong. Technology fails from time to time, about 20$ or so and relatively easy to replace

yes i think i have to replace the cable, but now i think i damaged the digitizer too..so i have to change both the ribbon cable and digitizer.
but i dont know why i cant see the bootloader and the boot animation.
thats my main problem now..
as i want to root my mobile again i need the bootloader page, guys please help me on this
then anyone having a desire z for sales?? (2nd hand sales ?)
I would probably just replace the ribbon cable before doing anything else digitizer is tied into the ribbon cable as well.

I too had the same issue.. I think the HDR option is not working in that ROM, so you better turn off the HDR.
I apologize for my english, i'm french..
I've the same problem. After a 1 meter-fall, it fell to the ground flat. Since, it doesn't work.
When i press the power button, the phone seems to start : vibration, and the sensitives touchs light. But i can't see anything on the screen, it stay black...
Do you think it can be the LCD screen to repair or the ribon cable ? If it was the ribbon cable, the sensitves touchs didn't turn on, don't you think ?
Thanks for your help, and again i'm sorry for my basic english..!

We cant guess it without testing. In my case i first faced problems regarding ribbon cable and slowly the prob builds up and now my screen is full back. But in your case it is most likely to be the lcd part.
So, better you make a test about it by swapping it into another phone or so..
then one more thing, even if the ribbon cable fails some part of it may work like sensitive light and touch..
I had the same problem. Just get the cable replaced.
Hi,
I 'dropped' my phone hard on a table and now the screen doesn't show anything. I can hear the phone clicks so that works. I've tried turning it on and off etc. but no luck.
Might it be loose wire or other part?
Thanks
If the screen remains fully black when you attempt to switch it on then its likely to be a loose wire. If there is a backlight then it could be either a loose wire or a damaged LCD screen.

There is a backlight indeed. I wonder how much I can take apart myself to find out. I can't see any obvious dents or cracks etc. on the screen or casing etc. so maybe something is loose?

There is nothing wrong with the software. The OP dropped the phone onto a table, that would have caused a hardware problem.

There is no point in trying it because it is a hardware issue. The OP can hear the clicks it makes when it unlocks and they try to hear it, meaning that it boots fine and there is a working kernel. Its a hardware issue, possibly caused by the ribbon cable to the screen coming loose.

I haven't disassembled the phone myself (I have had no need for it), however I have just watched a YouTube video and it seemed to be easy enough to disassemble and reassemble. If you look it up yourself and judge whether you wish to try yourself or not. If you have warranty from the store you bought your phone at it will more than likely cover accidental drop damage so if you don't wish to risk your phone then that would be your best option in all fairness.
Try the service manuals...
OK I opened it up and I couldn't see what the problem was. Nothing appears damanged, as expected. There are three main ribbon cables, none of them appeared loose. However, when disconnecting the mainboard from the phone case, the middle cable, which lights the LCD screen, has become fully detatched. It seems that unlike the other two cables, it connects via adhesive. I don't have thermal adhesive. When the phone turns on, now there is no backlight in addition to nothing being visible on the screen. PC Companion picks up the phone so all of that seems to be working. But no LCD and now no backlight. Unfortunately, there is evidence of me opening the phone. I doubt the warranty would be accepted now...?
In the reassembly video in document 1277-1354_Rev1 , it shows the three connectors just snapping/connecting....no glue situation.
If there is anything else I can do via home repair, what could I do? I can't be that far off, surely?
even if you don't open it, you can't file a warranty on SONY Service Centre if the damage is LCD, just buy a new LCD and replace it
Would that be the case even if I bought it locked on a network? How would they know it's the LCD if I don't say? Once before, with another smartphone, instead of listing everything I understood to the manufacturer, I told them almost nothing and got a full replacement.
Hello!!
Well suddenly there was no backlight so i guessed it was the LCD.. changed the LCD but nothing..
Ok the next solution was the Ribbon cable!! so ordered that and changed it too... Now the backlight is working again BUT i dont get to see anything other the noise on the lcd.. by noise i mean this grey thing like when the old TVs didnt catch a good signal!!! Does anybody know what I maybe did wrong?? Did i maybe injure the ribbon cable when i tried to squeeze it through the panel?!?! this phone has really cost me a lot of nerves... please help!!!

hi.
just wanted to chck with you again.. I got a weird problem again.
My phones back camera was not working. giving errors. my friend had a Xperia Play for parts.
I removed that Camera Module and replaced with mine. It started working fine. Cool. I Tried to switch on the Phone while holding the Battery by hand against the Board so I don't close the phone and then see what happened (Worked or not) but it was working so I though success.
I closed the housing of the phone !! Damn phone starts but Black Screen !! Vibrates but black screen !
I kept fiddling and though the flex had gone but no.
I re opened the phones removed the Camera Module.. and Their it starts working again!! I close the phone so I can use it without camera and Boom .. it doesn't work again .. RED Led Blinking !! Phone not recognized by Windows !!
where did I go wrong
PS I had replaced the Flex Cable a few months back and My Phone WAS PERFECTLY working until I opened to Replace The Camera Module !!

Hmmm. i would guess flex cable again, but red blinking could also mean problem with battery (or maybe even flex is even short-curcuit it somewhere)
Do you have some old broken flex that you know that it have working screen? And try with/without camera module
Or try with assembled (closed) part where is screen but keep motherboard part unclosed and try to power up
Just a tip: If you have black screen (and it vibrates ones when powering up) try again to power up but in fastbott or flash mode. If it enter in fastboot mode, but still it give you black screen, then it means that motherboard is working but does not have connections to display
Try to check battery voltage somehow. It must have above 3.2V to be able to charge it.

I thought to update you on this.
my friend had a spare xperia play so I thought to make use of it but its flex cable had problem and screen was Fuzzy and Snowy when switched on.
I believe my flex cable doesn't have problem ,, its the Connector where the Flex cable connects to the Motherboard. I am using my own mobiles "LCD and Digiter portion and his Mobiles motherboard portion" and everything works fine.
but when I connect my mobile to his Flex cable and motherboard portion it doesn't work at all.. same Purple Light when the Kernel boots but nothing on the screen. any suggestions how to fix the motherboard connector or maybe a hardbrick !
