Hello i have a MI5, and when i turn if off (shutdown) it doesn't want to turn back on... (Doesn't get recognised if i connect it to a computer does not charge...)
The only thing that works (sometimes) is if i open it up and disconnect battery connector, lcd connector and daughterboard connector.
I am on a MIUI 9 Global Beta ROM (latest) but it did the same thing on a previous version as well...
Anyone had the same issue or has any idea what i could do?
I dont have the warranty anymore...
Sounds like a hardware issue. You can try cleaning all connectors to make sure there is no stain on it. Give special attention to USB connector, this one gets stained easily.
Good luck, mate!

Hi i have had an x1 since august but within a month its been dropped and then it was unable to show the screen, i opened my device to try and fix my problem but messed with nothing whatsoever, when i put everything back together it wouldnt even turn on anymore! all it did was charge and when it was fully charged there was a red light. can anyone help me? please im desperate to fix my phone. My first paycheck was spent on this and i loved it despite the numerous flaws! also i havent charged it in over 2 - 3 months. Also when i opened it the tape that connect the rear and the front is kind of messed up, would that effect anything?
The tape that connects the front and the rear is the cable for the screen, so if it's messed up, you might need to get a replacement.
here is a pic, the red part where its circled is where i think the problem is, it looks ripped off, i did have a hard time opening and putting it back together the first time also.
Sounds like (Or rather, looks like) you're screwed, as far as I can tell, if it's really ripped. Otherwise attempt to clean the contact points with some cleaning alcohol and Q-Tips - something might have made it's way in when you disassembled the unit and blocked the electrical signals.
ill try it, but if that doesnt work, would i be able to replace the flex ribbon? would acteone work?
got this checked out by my friend, he told me its the flex ribbon cable, thanks for the help btw. Does anyone know the cheapest place to get a flex ribbon cable from?
Still would like confirmation if its my flex ribbon cable before i spend 40 bucks on a new one. thanks!
Hi, I am new to this forum. Sorry for posting here but I think I have similar or same problem with my xperia. Few days ago I drooped my xperia and then I could not turn it ON. I opened unit, the flex cable was detached.
After attaching the flex cable. I could turn the unit and it booted normal but no response on touching screen I even tried to align it but it did not respond. I turned off the unit. After trying turning it back ON only back light of the screen turned on (no sony logo, no xperia logo no winmo).
I tried to turn it on few times but same result. Even tried to soft reset and hard reset it but no difference only back light. Is it because of flex cable or because some thing else? I can`t even go in to 3 color screen. Please help. Sorry for my bad eng. Thanks.
So...I took apart my Nexus One to clean the dust from under the screen. I've done this before, but it back together and it worked. But this time, after putting it back together it wont power on. I sometimes get a vibrate after pressing the power button. One question though. This time I noticed that one end of the coax cable on the left of the phone is broken and there is no plug on it. Would this be the problem? I don't think it should though since I'm guessing it connects the GPS antenna to the rest, and I dont use GPS on my phone. Any help would be good.
EDIT: I think I didnt connect the LCD good enough.
The co ax cable must be connected to the logic board. If it won't click in connect it then secure in place with a small piece of tape.

As I said, the top plug of the coax has been ripped off.
Do you know if that's the problem?
Again, when I push the button it vibrates like it usually does on boot, but doesn't show anything on screen.
I pulled out the board again, trying to find the problem.
EDIT!!!! I just noticed on the LCD ribbon cable there are a few bent pins. I think that will be my problem. I'll get it back together in like 15 minutes and report back.
EDIT 2!!!! So yea...two of the pins came off, and are way to small to find. Guess I need to order a new LCD.
Crap, new LCDs are $60+
Hello Everyone!
So i'm really stuck over here. I have an international Samsung Galaxy Note N-7000 that is working but with a black screen!
First of all i want to discuss exactly what i have done:
1.i had a problem with the charging port where it works sometimes and most of the times doesn't. So i decided to order a new charging port to replace the existing one.
2. When i received the new charging port i instantly started to dissemble the device (The device was working perfectly before starting replacement)
3. After i removed the old one and installed the new, i turned on the device and it showed only a black screen, then after some time i saw the touch buttons light, but still the screen is black:crying:
4. so i decided to return back the old charging port and this time when i turned on the device it sounded like it's booting and working but still with a black screen. The phone even received call and the touch screen is working but with black screen.
What do you guys think has just happened to my phone? could the new charging port cause any problems with the motherboard?
i'm really stuck and don't wanna go to a service center
I have recorded a video of the problem. Please see it below
since i'm new over here, i'm not allowed to post youtube link.
please head to youtube and type my username and watch the video : nadeaa0a
thank you very much
My younger brother always liked to disassemble things with a hammer wondering after why it wasn't possible to assemble it the other way around.
It took him a few years to understand that real knowledge of things is a clear advantage.
Go to a service center and get help from a professional instead of making it ...

maybe you disconnected the wire you were changing ports ! don't worry and don't freak out just take to any shop and they will check it i don't think the screen is burnt because if it was it would be more expensive ! go to any shop and ask them to change ports and check the screen
for what you described, my best guess would be either you unplugged the lcd and didnt plug it back in properly.... or you damaged the flex for the lcd... the charging flex wouldnt cause the problem... just inspect the lcd flex and plug for damage... if no visible damage plug it in again and try it again... lets hope its just not plugged in right...
I have the same problem
Hi,
I have the same problem. I had never disassembled my phone and the screen slowly turned purple and started blackening out. It was fully functional. This I knew because I connected it to my Windows 7 computer and used Android Commander. I ordered a new screen complete with bezel etc. I have two batteries, the first didn't even charge after I put it in the phone (it had drained totally during the wait for the new screen), the second was partially charged and allowed the screen to boot. It is however behaving like the first screen did before it went black, that is purple. I am sure I have not done anything wrong with the connections. Could it be the batteries? or the adapter flex? I just hope it is not the mainboard. It is not on warranty and we don't have that many honest phone specialists around where I live. I am almost sure others have experienced the same problem and someone on xda knows what the problem is. If you do I would be indebted.

it shows as color black, or nothing (like locked device)? I used to face this problem too with my infuse 4G, but it was because of installing custom rom. Had problem with few rom i installed but nothing happen on my stock one. If your device is just not lighting up(like locked device), then i guess because of ROM, but i'm not sure yet. But if it shows "color black", then i don't know.
THIS IS NOT A SOFTWARE BUG. Its the Screen flex or the ribbon. Disassemble the back part, and take a look at the flex or the ribbon connector of the screen, clean the conector with a tooth cleaner with alcohol and let it dry for a few minutes. Put it back on and mount the back part again. Test it, it should work.
Same thing here: changed the usb port, booted fine, had issues with the sim, turned off took it apart again to check, put it back on and black screen.
Yea having the same issue here, dismantling the usb module and put in new one, power up black screen!! The menu and back button did lights up, and the phone is working too, can hear the booting tone, anyone got any solution for that yet?

You damaged your LCD flex cable or didn't plug it in correctly ..

I have unplugged and replug back few times, same result. Guess most probably i have damaged the flex cable. Replacement part seems too pricy to change, rather buy a new phone.

Hi,
I had a battery and ear speaker problem on my Xperia Z. I ordered the spare part and change them this morning. Everything went fine. The battery was a bit hard to take out.
I reassembled everything, boot and.. no screen Backlight is ok. I can hear the boot noise, but nothing no touch, no screen !
I try to reset, repair with Bridge on mac. Bridge said everything went fine but... no screen.
Any idea what's wrong ? A problem with the screen flex cable?
I can see some copper in some place (file attached)
It is not a software problem, just an hardware one. There could be two problems:
1. The flex cable above the battery is not properly inserted
2.The flex cable is damaged during the extraction of the battery.
Try this, remove the flex cable and blow some air on it and then try to put it back in and make sure it clicks
Thanks, already done that. I will try again. I hop it's not damaged due to the micro scratches
it clicks ... but still nothing
Hi all,
Last weekend I tried to fix the GPS on my Xperia Z (C6603) - it couldn't lock any satellite and according to all tests it was a hardware problem. When I opened the back cover I saw that the GPS antenna wasn't securely attached anymore (thanks to the third party who replaced my screen last summer I guess). While I was at it, I also wanted to check the speaker since the volume is generally quite low. Doing so I had some difficulty getting the battery out but it didn't look like anything was damaged by it.
I fixed the GPS antenna and reassembled the phone, but now it won't boot anymore...
When I try to boot it the LED blinks red three times and then stops. Nothing more. It only seldomly responds to a cold reset (vol up + power for 10 sec.) but mostly not. When I connect it to the wall socket or laptop the LED burns red continuously.
When I opened the phone I still had about 70% battery left so that should be fine. Nevertheless I've had it on a charger overnight (LED continuously red) and tried the next morning without success.
What I have found is that the red LED indicates either a broken bootloader or a hardware fault. Since it occurred after I opened the phone I would assume the latter.
I have managed to do a repair through the PC Companion software but without result. I can still get the phone in fastboot (LED turns blue) connected to my laptop to flash. The screen doesn't turn on, though I'm not sure if it should? I'm also not sure if being able to connect in fastboot excludes hardware failure?
I haven't tried to root/flash because I first want to ask for some advice on a more systematic approach to fixing it. Also, tonight I will pick up a friend's Xperia Z with a broken screen for spare parts (same model, he got it one month later). So except for the screen I have working replacement parts. Besides the screen replacement (with original Sony parts) the phone was still in original state both in hard- and software.
I would really like to fix the phone since I liked it and I'm stuck to a SIM-only plan until December still. Third-party repair is out of the question because of costs; then I'd rather spend it on a new XZ5.
Any ideas on how I should approach this?
After some trial and error, I have managed to flash a stock ROM (.253) on it. No luck with that unfortunately. When I try to turn it on, there is a small vibration after a few seconds and that's it. Again the phone responds to a cold reset, but when I try to boot it after the LED blinks red three times again. That's all it does.
I would say the only thing to still try now is swapping the motherboard with the other phone, not? Or are there any other suggestions?
Well, I would assume that it is a hardware problem, especially taking in to the account that you touched components inside.
Even if we all know how phone work, and where are all components are, its not recommended to touch anything inside if you dont have steady hand and environment to make any repair(clean place, no humidity, clean hands).
One bad plugged connector can brick your phone. One time I even had problem on other phone with really small rust on one pin that I touched with finger(sweat from it+time+really crappy weather where I had to use it), so it show how actually fragile phones are.
But few questions, when you managed to flash rom, you get all that android logo when you are in flashmode, and it show everything(loading bar etc) on screen?
Im asking because first symptom of bad battery connection is deformed or totally dead screen.
When you fixed gps antenna(that black plastic on top near camera) you used any tool that could damage board? its near microUSB so its easy to mess those small pins and make short circuit.
The same with battery, you could try to squeeze/move it a bit to see if there is any changes in phone boot behavior(not to gentle way to check it but sometimes it show if there is a problem)
Before changing motherboard I would replace battery from your other phone(charged before that) and check all pins on connector and board near it if there is any problem.
But as I said it should be made really delicate and in appropriate conditions.
Sadly I cant really help with it beside that, and I hope your phone gonna stand up after that somehow :/
Thanks for the reply Akinaro. Indeed the conditions are not ideal. At least I have one of those repair tool kits with the small screwdrivers, plastic pick and plastic levers for the connectors. I'll also set a reminder to take some latex/nitril gloves from the lab for next time

No, the screen is totally dead. No sign of life whatsoever.

Possibly. I have used both the screwdriver and the plastic tools, but fiddling everything back in was tricky. The battery was disconnected though so it shouldn't have short-circuited. I will try with moving around the battery. But the more I think of it, the more I start thinking that I screwed up the motherboard by touching something there.

I have tried the other battery last night as well. I didn't charge it first though, I left it in my phone to charge overnight and tried to boot it this morning, without result.
So I've attempted to swap the motherboards. Good and bad news...
The good news is that the spare phone works with every combination of motherboard and battery, so neither of those is the culprit. The bad news: none of the combinations work on my own phone, even with swapping all the other hardware components (camera's, gps, antenna etc.).
On the other hand, by now the LED doesn't turn red anymore. The phone just stays completely off. I didn't have time to try and charge it for some time though, so I'm not sure if it's a good or a bad sign.
I fear that the main multiconnector running under the battery might be damaged when I took out the battery and antenna module the first time. That is the only component that I cannot swap for it is so integrated - it would mean swapping the screen to the spare-parts-phone and using that one.
Any ideas still before I should consider it a write-off completely?
