I have had the second part of your problem before where screen doesn't come on but the back light and everything else works. A couple of months back when I was at college I dropped my phone really hard at a party( I was wasted ) and the next morning the screen wouldn't come on. So what I did was I looked up the guide to how take the X1i apart and luckily one of my buddies had the same screwdrivers that I needed because he uses it on his the Blackberry Storm 2. So what I did was went to where the Flex ribbon cable was located unattached it, then reattached it, and put my phone back together and the screen came back on and still works to this day. If this helps press thanks.

[Q] Phone works, screen does not yet sometimes it does

Hello
One night I was using the phone without doing anything special , some video watching . Phone went dark, tried to reboot. Blank Screen and the capacitive buttons flash. Left it to charge all night, in the morning it started but after I pressed the lock button blank screen but phone still working and receiving input.
Took the battery and SD card out left it for 30 seconds then started it again, Stuck at LG logo. Repeat , phone started ... Pressed lock button once then again to unlock , screen wouldn't start.
Used LG Mobile Update recovery tool to restore it ... Didn't solve problem. Sometimes it does not even start , just flashes buttons, other times it does without screen and last all works even the screen until first time goes dark , in the last two cases I can use LG On-Screen Phone without trouble, in doing so I installed a proximity sensor test app to see if it was causing my screen to not come back on , the sensor looked fine.
Facts:
1. Two day old Optimus Black p970, worked like a charm until stated problem
2. The app that checked proximity sensor showed the sensor to be free when my hand wasn't on it
3. The warranty laws in my country are idiotic so I would do or buy anything rather than send it so they can give me a new one in 3 months.
4. Tried another battery from another Optimus, fully charged nothing different.
5. Stock rom.
Do any of you fine people have some ideas on how to fix this? Thanks in advance

Hi there...
Sometime ago [1 year and a half or so~] I worked at a cell refurbishing facility [there were samsung, motorola and palm devices from sprint] and that problem you have was quite usual. Blank screen, still the phone is somehow usable like reciving calls...
There's this thing called "flex" which is the connector between board and display and that is what we fix, most of the time not even "fix it" just getting it in the right place...
This happen because of excesive use in those sliding or clamshell devices, in OB could be for overheating, you could try to fix it yourself or pay $20 usd [that's what it cost here]

Would that connector explain the fact that sometimes it doesn't start at all? hmm I am thinking now and I guess if it moves and somehow the phone feels it has not display connected it could fail to start... Anyhow thank you

actually yes, it could be only for the flex [some devices don't start at all when not having display or keyboard if there's any] but since our OB is not sliding nor clamshell type probably was overheating.
you say you have stock rom, well now I'm using CM7 but when I was at stock and after using the phone a few minutes it felt warm and some more minutes [like playing gunbros where you need to use both hands and a lot of movement] it was really hot and had to stop playing for a while.
what I'm trying to say is that because of overheating flex could have moved, but because of overheating too may have move something else, you couldn't belive the huge number of micro-things that reside in the board.
so if it's only the flex, it's an easy task to do, just unplug and plug again, but if it's something else it's quite hard to know just looking at it, you need to do some electric measures and stuff, the recomendation is to take it to a tech center or something

Hi. I Have same issue. Two times when i press power buton, butons flashing and screen still black. Phone not responding. I must remove baterry.

Hi there, got the same problem too with my optimus black. Screen goes flickering, shut down don't do any good, and the phone temperature is kinda hot. But in my case it work after I clean some cache and data in the phone storage through LG OSP. After that, the phone temperature back to normal and the phone screen back to normal also. I believe that in my case the phone is overheated.

[Q] [HELP] Black Screen but Functional Device. Galaxy Note N7000

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.

New display assembly won't work

HI guys,
I want to post on behalf of a friend who has a problem with his Xperia Z1. He originally bought it used with a broken display, he then changed it with success, the phone was working fine until it fell. At this point the display was still working but not the touchscreen, so he ordered a new assembly from the net (not genuine, like the first one which worked tho).
Upon receiving his new assembly, he immediately started the repair. However, when he turned on the phone, he only felt the vibration and nothing appeared on screen. No any light, he got a totally black display with no sign of life, while the phone was fully charged, and was recognized by Windows (he could even access his files on the memory).
He obviously thought that the seller tricked him and that the assembly was defective but when he tried with the old one (which had the display working but not the touchscreen), the same result showed up, no light, like the assembly wasn't plugged to the motherboard at all.
So far that's what I told him, check the connections to the motherboard, and make sure the flex ribbon is not damaged. He even bought a new ribbon and installed it, with no success.
He read that the problem can come from the display ribbon touching the chassis, thus making a short-circuit, but I doubt it. How if the display connector on the motherboard is broken? Is it fixable? Like buying a brand new connector and soldering it.
Thanks in advance for helping us

Try a hard reboot by Golding vol + and power until phone vibrates. Is the backlight working?

Thanks for reading this long problem
Sure, he tried the hard reboot thing, he even successfully flashed a stock ROM but nothing changed. I can only think of this as a hardware problem, but what part is defective?
The motherboard connector?
The ribbons on the chassis? But he changed to new ones already!
The LCD assembly? Same, the one he tried is a new one...

Still no one to solve the mystery?
I'd like to add that the phone turns off itself after approximately 30 minutes in idle state. That is, the explorer doesn't show the phone anymore and it has to be powered on again.
I know the best solution would be to buy a new motherboard or just forget about this broken phone, but it's a challenge to fix something that is apparently hopeless

Red LED flashing: bootloader bricked, hardware fault, or a write-off

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?
