Hey guys how are you!
So my beloved evo's lcd broke and i just replaced it today. The strangest thing is happening.. the screen turns on fine, but once I turn it off, it wont turn back on. The three buttons at the bottom light up and the screen, i can tell, turns on. But I cant see the UI. It is definitely not a software issue and I have tried reseating the ribbon cable multiple times. What the hell? Is my evo too old? only way i can make it work is with a reboot which is super annoying.
I have one with a shattered screen I will be replacing soon. If my memory serves me correctly there are several different types of ribbon sizes. Hopefully that is not your issue. I would suggest using a bright light and looking into the female receptacle (no dirty jokes please) and make sure that nothing is bent or twisted. Also check cable that none of the connections are not chipped.
Not sure if this will help but it is worth a shot. Other than that I am not sure what could be wrong.
Peace,
Love, and
Happiness
Edit: well fine honda but just one and you have to promise that it will be clean

The screen turns on fine. Its something I've never seen or heard about.
Well what caused the problem in the first place? Did ir just stop working or was it an innocent victim lacking the proper protective coverings?
Either way there could be more hardware problems than your screen. Give this a try and tell me what happens. Plug your phone into the charger, if nothing happens with the screen try connecting to your pc, and if still nothing try a rom that has the volume keys to wake aokp/cm are a couple that I know have that option.
If that doesn't work I will see what else I can think of.

of course if you can't find the receptacle, you'll want to take hold of the dongle and have it cough a couple of times...let us know the outcome, please!
But seriously, so is this what happens?
You turn on the device. Powers up ok. You can see the screen. Then what? How long till it disappears? Are you doing anything when this happens? Can you unlock the phone and see the desktop? How do you know the screen turns on fine? What exactly is giving you this impression?
Sounds to me like another broken lcd. Do you have another phone you can swap out the mainboard and help isolate the problem: mainboard or lcd/digitizer/connectors.

It powers up fine and then as soon as the screen turns off (either manually by me or by timeout), it will not turn back on. The screen powers up, the lights at the bottom turns on but its a very dark grey screen. And as you said, isolating the problem would be easy if I had another mother board. I have another one with a wide flex cable IDK if should request a replacement or if i should get a more expensive, OEM LCD.
Ok questions for you.
Stock/rooted
S-on / off
Rom/kernel combo
Min/max governor
Oc/Uv
Everything thing else works
Power button (I say yes)
Volume +/-
All 4 screen buttons
All points of screen responsive
If your on a rom that supports volume wake try it
Auto brightness off/on

I did my research, man. Literally tried everything. Its not software, no setting can fix it.
Think it could just be an issue with waking? The lights coming on but just a dark gray screen has happened to me with several ROMs. Bumping up the minimum CPU speed a notch or 2 usually solves it.
I asked the seller and he said it is not oem. Do you guys think it makes a difference and if I should suck it up and buy OEM?

That's what I though at first. Hours of tweaking and research and I figured it cant be a software issue.

Hi all
Just got my new unlocked One X today, but already I have problems with the software, Back, Home and Apps buttons lights going out out.
They seem to come on and off when ever holding the handset at a strange angle or position. Is this normal or is there a setting that needs to be changed to stop this from happening, or more likely the handset has a fault.

I am not sure about this but I never noticed this while on 1.26. Someone "complained" about it and I noticed this on 1.28. The 3 button led light only come on at night. So they are now sensitive to ambient light. Try to cover the front top part and you will see them come on. Remove your hands the led's go off.
But as said, I am not sure if it was like this when I was on 1.26. Didn't take any notice of that.

Haha... buttons illuminate at low light/night time conditions, no fault.
u can adjust the sensitivity with a rooted device but that is another story for another day.
Wow, I feel so thick.
I was so close to packing up the handset and sending it back because I thought it was faulty.
Cheers for the help.

I was thinking the same thing. They are defo run on light sensor but it is too aggressive. If there is a small lamp on in a normal size bedroom they go out yet the light is no where near enough bright enough to see the buttons with out their lights on. Its making me have to send the phone back. Oh well SIII here I come..Pity! :-(
Soo close...

I have just had similar problem except my light stayed on, if I held it, the software buttons would flicker on and off and if I tilted it backwards would dim, even stayed on when phone was turned off. HTC tech said that it was faulty and the phone is being replaced.

Does anyone know how that works. I would prefer that they always stay enlighted, when screen is turned on. I´m using Viper X maybe that can help...

For Venom-ROM I found it searching the Tweaks. Go to "Button" and set "Capacitive Backlight" to "Never " and they´re always on, when your screen is on. There are some 9 differeint steps to control the sensitivity.

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?

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:
This is my first thread so forgive if i put it in the wrong place. I wasn't sure where it should go.
So did the usual phone user mistake and dropped (threw) my phone. cracked the screen pretty good. I've messed with phones for a while now so i purchased a new screen and digitzer and tore down the phone. pulled the old screen off, replaced it with the new and everything was good as new. ran some tests with video and quick touches as well as multi-touch and zoom. everything worked great but i have no vibrate. the phone can be put into vibrate mode but it doesnt vibrate. i tried factory reset, though i figured it was hardware and not software. If anyone who has torn down these phones knows anything about the vibrate can you please guide me into fixing this?
On a side note, i also broke a little golden clip off the inside later when tinkering trying to fix the vibrate (im pretty sure it completes the circuit for sound because now i have no sound).
Bump. Sorry but this is kind of urgent. does anyone have any ideas on this?

It is possible that the connector came loose. Try checking that. The motor could have also been damaged so it make need to be replaced.

Here's a video that shows disassembly and removal of the button assembly. It doesn't look like the switches would be the kind that would stick, so it's probably crud in the buttons. You could try to remove and clean the assembly, but if you are still in a warranty exchange period you might consider that.
I'm hoping that different color buttons come out soon. I'd like to change mine out for red, white, or blue.
Back on topic please... If you haven't anything constructive to say then please don't post at all... No one wants to see people arguing over something here. Regardless of who's thread this is the forum rules still apply to all.
Thread cleaned
I just confirmed this happening to me, but I think it's been happening for awhile. I'm going to warranty exchange because even without touching the volume button, it is constantly trying to lower itself as if I were holding the button down continuously. Serious glitch... Not only prevents listening to music, but also interferes with any other buttons/typing.
I have a KGL unit with RK3188 quad core CPU and 1024x600 screen.
I was working with custom ROM (made by Malaysk)
I didn't update anything recently.
Suddenly that morning, the screen is black.
I am able to hear the radio, and Bluetooth calls are being transferred through the unit, but the screen is totally black, zip, nada, nothing at all.
Any ideas what could get wrong?
I've had this happen before also. Do you see any boot logo at all?
Dave
I see nothing at all. Black all over the way.No logo

Did you tried to enter the recovery or it is shows black screen also?
If yes, maybe your display panel is wrong. If you seller ignore your messages, try to check your panel's contact to the board.
Check to see if you can get into recovery. If screen works, turn off lights when in rom. I had issue with auto brightness which was too low. Only way I could fix was to wipe and reinstall and turn off auto brightness.
Just updating... it was a hardware problem.
Flat cable problem + certain transistor.
Thanks for your comments.

The buttons were OK, I was able to listen to radio, switch stations (via the wheel control), and even BT calls went through.
That made me guess that this is a hardware problem, and not software.
and no matter what you did you never got video ? Ive got this same problem but after a hard reset Ill get the video back sometimes.

Actually, I even didn't try to hard reset the unit.
Took it from my technician, and it was working, without any hard reset.
To be precise, I'm going to visit him again tomorrow, since the colors on the screen are a bit on the green side, and a bit smeared.
Not a disaster, but not as it should be.
I guess one of the flat cables inside the unit, is not in its place.

I had a similar issue - would lose screen output, it would go either black or white. Touch screen would still work, and radio/BT as well.
Then I'd disconnect the flat cable and reattach it, and it would work for a couple of days. Final solution (it seems) was to hold the flat cable with tape/hot glue!
Thank you, mine just went out again, it was fine for a month or so after reseating all the ribbon cables in the ZIF connectors, I'll do it again tomorrow and try securing them with some tape.
