I took my phone apart and replaced it with a new housing. When I press the power button, my Xperia vibrates as normal as when it starts up. However, the screen stays black. I can tell the powering up is fine because it vibrates and the keyboard lights up. Have I missed a step? I use these videos to disassemble and reassemble my x1..
Edit: Sorry, I am not allowed to post links. But it's the Rear + Front assemble videos from user CyK1 from Youtube.
Thanks
The only reason your screen won't light up is the flex connection to the mainboard. That, or the LCD connection to the flex itself. At some point during the housing replacement you either didn't connect it properly, or damaged it. You will have to go all the way in and check those connections.

Hey
A friend of mine called me yesterday if I wanna buy his broken X1 (it felt down :/) and repair it, because I'm the man for such jobs
Do you think it's only the LCD-flex-cable or another repairable damage?
I think I can get that device for 2-3 days and then decide if I buy it...
Some ideas? Is there any chance to repair it?
Thanx, Carbon
yes, probably even a loose connector on flex cable
Hello,
I am quite certain it is an easy problem, i have seen many x1 phones with just a minor loose connector which causes the screen not to respond.
The best way to check it if it really is just the screen/flex cable is to turn it on, and check if the side lights flash in all colors.
If that works the phone should work normally. (even if the screen doesn't work)
After opening:
Re-insert all the cables in the screen flex cable and check if it works..
if that doesn't work then replace the flex cable.
If the screen works:
Then check out the screen if it has any crack's or black spots.
In that case you will have to replace the screen/touch screen also.
Generally, if there is no physical damage to the LCD itself and the phone buzzes on startup with all appropriate sounds - replace the flex. Flashing lights are attached to the flex and are positioned ABOVE the LCD on flex connection, therefore will not light up if the flex is damaged and neither will the upper keypad and other less obvious things.
The flex replacement is not minor, just be aware of that. Bad falls are also the reason for main PCB damage, in which case there will be nothing you can do.
Thank you so much
It was a "very short" call by this friend, but when i take the device, I want a precise report what happened...
atm I don't now if the sidelights show reaction, but I will report
I'm afraid of a real PCB damage...
In flex problem side lights will not light up, as i mentioned, they are positioned above the Lcd connection, so if the main flex connection ribbon is damaged, as is most often the case, all of the upper level functions will be gone, but you will get a startup with buzz and sounds present.
I got it
And LEDs are flashing and you can start it complete normally, but you see nothing... i'm going to open it and check the Flexcable

Best of luck.
So yesterday my toddler son was playing with my Sprint Diamond when I saw him drop it onto the carpeted ground. The phone probably fell maybe about a foot but I guess the angle it hit the ground caused the battery cover to pop off.
When I picked up the phone, I noticed the screen was off and assumed it was in sleep mode because the battery didn't dislodge or anything. But when I pressed the power button, the phone wouldn't come on. I tried pulling the battery, hard resetting, etc but the screen still won't turn on.
While I was playing around with it, holding down the volume down button, power button and enter button at the same time, I could see the screen come on for a bit, then go blank again.
Physically there's no visible damage, there isn't even a scuff or scratch on the corners where the phone probably hit the ground. However, by some freak chance I think the fall caused something to go wrong internally, maybe the LCD digitizer became loose?
When I pull the battery and restart the phone, it vibrates as if it were powering up. But the screen never comes on.
Considering I don't have insurance on the phone, taking it back to Sprint is not an option and I'm out of the warranty period. Has this happened to anyone before? Any advice? Anyone have experience disassembling a Diamond? How hard was it? Thanks in advance.
the diamond (sprint) is a layered device.
you will need some very small screwdrivers lots of light and patience.
the screen is glued to the digitizer and the front housing, removal from the housing WILL crack it.
the boards and lower button pad con be removed safely, for inspection/reseating of plugs.
if the problem is not a loose plug,than a new screen and digitizer is in order and available on ebay from china
Hello.
Could you explaine what is wrong with my phone.
I`ve chaned the digitizer. Everything after that looks good & the phone is booting.
But I can`t see anything. There is no picture on screen, only light, sound & vibro.
When pluged into the PC it`s vibrates & sounds.
I`ve tried to boot bootloader mode but I can`t see what happend with it. Digitizer start vibrates after pressing VOL- + Power.
ZUNE writes eror code C101002E.
Please, help.

The Lcd is a very simple device, it's either working or not much like a pc monitor. If you properly reconnected it to the mobo it should display an image regardless of whether the digitizer is working or even on the phone. Take the back cover off and recheck the connection. You can also check the connection with a magnifying glass to see if you bent a pin. If you still don't have a visible screen then most likely you damage the lcd when removing the digitizer strap.
tnx

find new LCD. Had replaced it. Everything woke good. Thanks alot.
Hello, guys!
Recently I bought an HTC One with cracked digitizer, but functional. It had a lot of scratches etc, but this is not important right now. I wanted to do a complete make-over so I bought replacement parts from the internet, I bought the front housing with the LCD screen and the back cover. I dissasembled the phone from the old housing (the one with the broken digitizer), and I assembled it back on the new housing. After all of that, I powered on the phone and it worked like a charm (the LCD and the touch-screen worked perfectly), but then I saw that the glass was a little out, I mean it was upper than the speakers cover, so I decided to take out the whole screen and to change the adhesive, because it was too loose and the screen wasn't staying properly. I succesfully did that, i put the screen back and everything was good, but when I wanted to start the phone, the screen remains black. And this is the problem I have. I mention that I worked very carefully with the screen, so I don't think the problem is at the screen. I disconnected and reconnected all the cables and still doesn't work. When I press the power button it vibrates and then it's making that sound like the phone is booting, but no image on the LCD. If I keep the power button pressed, the back and home buttons are blinking and then the same story as before, vibrates and then the sound. I really don't know what could be the problem.
I really need some help with this and I'm open to all of your suggestions. If you want more informations feel free to ask.
Thanks in anticipation!
To me it looks like you damaged one the flat flex cable.
When you took the screen out did it come like suddenly and maybe some tension was applied to the flat flex?
If I were you I would take it apart and verify the connection in the socket, maybe the socket was damaged or something and it doesn't make a good connection
I hope it works out for you
Thank you for your answer!
When I took out the screen, I took it out very carefully and there wasn't any tension applied to the flex cable, so I don't think this is the problem. I think it's more likely a problem with the socket on the motherboard, like you said, and it's not making a good contact. But what can I do about that?
I bought this Lumia 1020 off eBay with a broken screen. When I got it the LCD didn't work so I ordered an all in one piece thinking that would fix everything. I put the screen in last night plugged it into the charger and the windows home button blinked until it buzzed but the screen never lit up. I can hold the camera button and the camera will make noise and the flash will go off but nothing else. I can push the screen buttons and they will vibrate but the screen wont light up. I plugged it into the computer and saw that I was charging and had 20% battery power and climbing. I tried to use the windows phone desktop app but it just told me the phone was locked. I took the phone back apart and realized the proximity sensor ribbon was separated from the front camera ribbon. Could the phone shut the screen down if it doesn't get a signal from the proximity sensor? Any and all help is appreciated and thank you in advance.

Can you press the hardware buttons (back/home/search) and it vibrates? I suppose the screen/touch panel is not correctly connected to the device somehow...
