Lumia 800: no display, charge trouble - Nokia Lumia 800

Just like to write my experience here:
Phone:
Nokia Lumia 800, unlocked
Firmware: 1750.0805.8773.12220
Problem symptoms:
Unsually no display
Can not switch ON
Has vibrate feedback while switching on
Will not connect to PC for long (only about 2 Seconds, as HID device)
May respond to charger connect with a vibrate
Does get warm while charging
SOMETIMES will have display, but usually not for long
I noticed:
have display and charging are not related.
Longer charging does not make it more likely to have display
After putting the phone in the fridge for 15 Minutes it starts right away!
Conclusion:
There is a relationship between heat and malfunctioning.
Action taken:
1. I put the phone in the fridge for 30 Minutes
2. Then put it between two milk tetrapacks (cold and closed of course!)
3. Connect it to Zune
4. Did a backup
5. Installed the latest firmware in the hope that it works better
The whole update process takes about 1 hours.
Version after update: 1750.0823.8852.12430
Sobering, the start and display problem is still there. The hope that this was fixed with software did not materialize.
Update:
The last few days the phone was totally dead. No response to nothing. I thought maybe the LCD was bad (I know, stupid, because it should still vibrate) and I brought it with to one of that cell phone heaves were you can buy every single part for every phone produced in the last 15 years.
To find Lumia 800/N900 LCDs were no problem. There were plenty. I changed the LCD (takes me now 2 Minutes) against another, and another - no change. Dead.
Then the dude had an open Lumia 800 (or N900 - they look the same) - I tried my LCD there - no problem. Then we swapped batteries - still my phone stayed bad. At that point the dude talked about bad main board.... but I was running out of time and had to break up. I finally excepted that the phone is bad.
Well, today, 3 days later, I plugged it in to my PC - suddenly LCD came up and it works normally. For now, but I doubt for long. (just had the USB cable disconnected and the battery level dropped from 12% to 6% within a Seconds)

Same, same, but I got workaround

I have the same problems with my L800.
When my batterys are completly empty. The phone is not starting, after plugging it to a charger.
Everytime it runs in a restartloop. Like Buzzzzzzzzzzz ...... buzz ..... Buzzzzzzzz ... buzzz ... and so on.
Workaround:
I let it charge (or loop) for about 1 hour. Then I disconnect the charger. After 2 minutes I start the phone. And as far, as the bootscreen appears I plug it to the charger. (Remark that the battery is still completely empty). Now the charge proceed correctly and everything is fine again and no loops.
I hope I could help. My L800 is on the way to cutomer care.

im having the same issue, is there a solution for this?

I have no positive update. Sometimes the phone works perfectly for a few days, then it's dead for a few days. When I cool it then it charges better and I do get display.
So this morning I went to the Nokia Care center, I charged the phone in the car, and fixed it to an A/C outlet. It worked fine, but when in the shop it was warm again and didn't work (means no display, it had touch feedback). The girl connected it, but seems there was no response. They want $50 just for looking at it - and in case it's the main board - that would be $260 (The Lumia 620 sells for about $200 official price).

I gave up on the Lumia 800 !
If I buy a sparepart there is a chance that still something else is broken. Pity, I love the OS and the form factor.

I didn't touch it for a few month. So yesterday I charged connected it again to the PC. No display. Sometimes it connects, and disconnects to the PC (the PC makes it sounds then, still no display).
When I switched off the PC the phone made a sound - that made me curious!
So I switched on the phone and to my surprise got the low battery logo on the screen. Even though the phone was plugged to the PC all day and got warm too.
Anyway, after a 2nd start button press it booted to WP. I connected immideately back to power and it stayed fully functional most of the time. Battery was about 6% first, and it continued to charge. It's >90% now.
Just now it crashed for no reason and restarted. Sometimes I get a cracky yellowish screen and the system crashed (have to add that my screen is not original).
Now my question: is there any tool that lets me check the hardware ?

Phone won't boot up

I have a Cingular 3125, working fine for weeks, happened that two days ago, I was charging the phone and transferring files to my computer via Bluetooth, nothing unusual, then it just got frozen, nothing responding, so I just took out the battery to manual reset the device and reinserted it, then tried to turn on the device, but it refuses to boot, no lights at all, also when I attach the phone charger, it doesnt show the usual orange led when charging, but I can feel that the phone gets warmer because the charger is attached and then after a while it gets a bit cooler, just like when it finishes charging, the usual behavior, but again, no lights at all trying to boot it or even attaching the charger, I've tried taking the battery off for hours and nothing also, and I wasnt overclocking the phone... would you say it just died? or maybe someone had same issues and solved it someway? thanks.
try this
OK, I don't remember where I read this, or the exact procedure, but give this a try.
remove the battery, press and hold the red call end key (power key) for 30-45 seconds. insert battery and do a hard reset, IE.. power on holding the 2 top soft keys while powering on the phone.
this method is supposed to clear any mother board issues and reset the phone. It has been a couple of years since I read the procedure so I am not sure if this is the correct way, if it does not work, try the same thing, only try taking the battery out, then put it back in and press and hold the power key for 30 - 45 seconds.
may or may not work, but can't hurt to try.
i had the same problem with startrek which i had bought from eBay
one more advice - try to hold record (notes) and camera buttons and insert an USB cable to your PC, it should enter to Bootloader mode
well, I have dissasembled the whole thing, I havent reached anything, even disconnected the backup battery, nothing, have checked battery with a multimeter and is full loaded... in short, someway the cell phone seems has just died, Erofich, to enter bootloader mode, the phone must turn on, it just doesnt want to start at all, no lights when connecting charger or USB cable... I'm sad because it was working fine with no problems for three months and more sad because it's the end for me to windows cellphones for a long time, I've invested a lot in this phone, accesories, unlocking, and even the same day it died also bought more memory and a neat skin cover and I'm not in mood to invest more in a cell phone so I'll use a spare crappy feature phone.
Thanks for your support.
one last effort
You could try one last thing, this has worked for me with a couple of startreks,
take the phone apart, and take the motherboard out, use a hair dryer to heat the motherboard, don't get crazy with it, but using the hair dryer on the high setting for about 30 to 45 seconds at about 3-5 inches, might revive the phone. (don't heat the battery, just the motherboard)
Put the phone back together while it is still hot (but not so hot that it will burn your fingers) and try to fire it up.
This has worker for me in 3 cases (phones that I bought off eBay that had the same symptoms as you have described)
good luck
big problem!!!!!!!!
I have been struggling to flash (again) the great pro V2 rom, but I always used my VMWare based XP windows version on my Vista laptop. Today I could use a genuine XP Laptop and I could make a connection and start the upgrade!
Sounds good? That's what I thought too, until the upgrade stopped at 70% (and I didn't touch anything), because of a connection error. I followed the text on my PC screen and I finally it started flashing again for a few seconds and then my startrek suddenly restarted, but it stops at the first splash screen! I tried to get my device back to bootloader mode (push 2 soft buttons and start), but no bootloader mode, only the 1st splash.
I solved the problem.

[Q] Battery empty phone not booting anymore

Hello, i've a small Problem with my brand new Lumia 920...
yesterday i got it from postal service, after installing everything the battery got empty... ok no problem... pluged in the charger, i know from my HD7 that it could take a few minutes that the phones charges a bit before next boot...
but the lumia 920 didn't boot also not after about 1 hour on charger...
i just see the nokia messages then a small flicker line on the bottom of the screen and then it resets (i know it resets because the recognized devices, nokia bootloader and another one, by windows disapears)
and the "empty red" battery symbol apears with a charger sign when plugged in (whats normally be total normal) when trying to boot without charger then just the "empty red" battery symbol apears!!
when on charger, after the batterysymbol, i can see that the display isn't turning off, just showing black but has some light on it... definitly not that black when the phone is turned off completely...
yesterday i tried a few button combinations... plugin with volume down, shows a flash on the screen... after that the phones boots normally..
today i ran out again of battery, but now nothing helps...
anyone got this issue too?? any tip what i can try or do??
are you using the original charger?
The 920 needs high current charger in order to charge normally.
yeah i had this to about a week ago, just sit it on charge for a long long time with the stock charger. mine took probably 4-5 hours, then hit the on button and it came on (still saying it was flat, but turned on at least). havent had the issue since.
Edit: also, are you running stock rom? just wondering as im on flashed portico and i literally just saw another bloke with the portico update complaing of the same thing... which has me wondering if its firmware or something else..
Hello,
i guess i have the portico update allready...
my carrier released the phones 3 weeks ago...
i'm on 8.0.10211.204
1232.5951.1249.1002
i'm using of course the original charger that have come with the phone...
as it looks like it really takes many hours... so as yesterday on mine... i tried everthing... than i decided to let it alone... after watching TV the phone rings sometimes about a new message... !? wtf.... i will try next time when the battery rans out to just let it on the charger a few hours without trying to press some button combinations or disconnect and reconnect a few times ...
but i'm pretty sure this has something todo with that, that the screenlight is still on when on charger and this batterysymbol w charger icon apears or better said than disapears...
i thing the display still drains current and so the charge take longer to have the minium charge for boot... ?!
I have the same problem after I flashed it to portico
my phone still charging for 1 hour to start up & when it done the battery was 6%
ok, no i've changed my response, my phone went flat yesterday about 7am (perth time), its been on charge since, and no boot. (what am i up to? 27 hours?) ive tried different chargers (my Qi wireless charger, stock charger, random microusb charger), even tried different wall sockets. stressful....
Edit: sent back to nokia. apparently its bricked. also, holding the volume down button and plugging in the charger is meant to display an explanation mark while the phone is switched off. the person i spoke to at Nokia asked me to do this, but mine didnt display anything, thats when she decided it was bricked. i wonder if its anything to do with flashing the custom firmware... apart from this issue, the rom felt very stable.

[Q] Sleep of death (won't turn on)?

Anyone getting the sleep of death on their XTZ2? I'm running completely stock (not even rooted) on 23.0.1.A.4.30 and just experienced the unit not turning on at all until I do power + up volume.
Upon returning to life, the battery was 90%, so it wasn't battery.
Had a bit of a panic attack until I googled the solution (power + up) but this is the first time its happened to my unit, could it be related to the recent upgrade to 23.0.1.A.4.30? Anyone else seen this?
Mine lasted a day and a half after the 23.0.1.A.4.30 update and then became very erratic and kept forgetting wifi login info.
Did a restart and certainly got a sleep of death OK.
Would not switch on at all.
No power + vol up or attempt at repair via PC Companion made any difference to it.
Since gone back to Sony for repair, that was weeks ago, who knows if /when they will return it.
I had the same problem with mine as well I have the 561 the Verizon model. I have received a replacement but have not been able to get it to turn on either. It shows no signs off life at all not even when connected to power AC or PC. My old one would blink red and go dead when connected to a PC but this one doesn't even do that. I haven't had time to call for another replacement yet but really two defective devices in a row the second one didn't turn once.
Finally got mine back from Sony repair agent.
Worked fine for 3 days, then failed to power on again as per original fault.
Once again returned it for repair.
Think I'll give up and buy an iPad instead - at least they seem to be reliable and consistent.
This just happened to my tablet this morning. Tried all options under the sun but can't get it to boot.
I can't even do a factory reset and I don't particularly want to return it under warranty.... :'(
Mine is an xperia z2 tablet sgp561 (USA Verizon) build 17.1.D.0.437, stock 4.4.2. This issue happened to me 5 days ago after I powered off the tablet, it won't turn on again. Battery charge was ~70% at the time. Plugging it with factory Sony usb charger won't do anything, charging status LED remained Off, power button unresponsive. I let the tablet sit for 2 days without charging cable connected hoping the battery will drain completely by itself and the buggy firmware will restart executing at its base address getting out of the bug. Then I connected the crap to a fully charged 15000mah Anker power pack and alas, the charging status LED glowed red and after ~5 more minutes the LCD screen turned On for ~5 seconds showing a big battery icon at the center of the screen indicating 0% charge. Waited about 1 more hour and the charging status LED turned amber. This time I did the "power button + volume up" ritual holding both buttons for 10 sec+, expecting 3 vibrations but didn't feel any. At this point the tablet is still powered off. Because LED = amber, thinking battery must be at least 10% charged by now, just pressed the power button for ~2 sec and surprisingly the normal power On vibration came followed by Sony logo on LCD screen and the rest is normalcy.
From what I can remember, the recent change I made before this problem happened was turning Stamina to On in the battery settings (factory default is Off). I reset all settings back to factory defaults and so far so good.
Finally got mine back from Sony repair agent after about 3 week wait.
Seems to work OK now, fingers crossed it will keep working this time.
The note that came with the return indicated that they replaced the mainboard and battery, which is a better solution than their first attempt which was just to reflash the software.

Dude same thing, WTF is going on, I tried plugging it into charger, nothing. And once I got the msg of red colour battery icon and then I plugged it in. then it started charging and I was happy so I turned it on the it wasn't charging,
Please update me what happened and what they are saying cause I am about to send mine to get it fixed.
Edit: seems that by replacing the battery and mainboard has actually fixed the issue? Guess it's time to send it back to them, Gosh

Did this method work for you? Plus did you come across like it was charging but it wasn't really charging,(like it showed the low battery stat with orange/red colour LED notification but suddenly it vanishes) then it's not responding at all.??
I had this issue 2 times with months in between , no response from power+vol up , no lights when charging , no response from pressing on the red button behind the flaps.
The last time it happened i tried putting it on the charger for a whole day with no result, then decided to let it rest a few days first , since someone had the same issue and it magically came back to life when he got back from a vacation.
So i try to turn it on 2 days later and the tablet to my surprise responds again with blinking red LED, recharching afterwards did the trick and worked again since
In my case i was running CM11 at the time, both times it happened after an update which required a reboot while, still mistified about the cause and the fix , i presume it solved itself by letting the battery drain.
Since then i reverted to stock rom just to be save but havent had it happen since, this also seems to have fixed some touchscreen problems i was having at times.
Hope this helps.
Bloody hell, I've just ordered mine today!
Don't stress. Mine got repaired. if it goes tits up that's what warranty is for
What did Fonebiz indicate was wrong with your Z2.?
They replaced the motherboard in mine.
Exactly the same, works fine now
This just happened to me today. So seems like overall suggestion is to try and let it discharge. The try to start it back up and charge it then. Just want to make sure that's the only potential solution now?
No! Leave it powered off, put in on a known good charger for at least 12 hrs. Don't touch it in that time.
If it does not come alive after that, send it in for repair.
ok..let me try that. I originally tried that and nothing occurred. However, I just found the OEM charger and usb cable and will try that. Unfortunately it's a Verizon version so sending it in will not be covered by Sony warranty. Per the Customer Service that I called.
ok..tried another charger and the red light came on, but it's been over 12 hours and still no go. I did notice that the red light was no longer on (from overnight charging). I left it unplugged for a bit and reconnected. The red light came back on but still no response. Sounds like i'll need to send in?
Looks like it.
Had the same problem on tuesday. Impossible to switch on, no light, none effect with charger, none effect when connected to PC/MAC etc...
After 4 days without charging my Z2, it came back to life, showing only a big red battery icon when pushing some seconds on the power button. Connected to a charger the red led indicator glowed ! (red battery icon is totally different with the original icon when tablet is charging in power off mode)
After a full battery charge with OEM charger and after a normal power on, my Z2 is now perfectly functionnal.

lumia 800 overheated and failed to sustain reboot replaced with new battery all keys

all key combinations have failed to produce boot and screen but the vibration responds quickly to the sequenced key combinations. no password issue always seemed to need a reset and extra attention but worked fine until left in partial sun through draped window and was powered on without a cool down. I heard a hiss and though the battery was discharging itself, tried when cool nothing so I put new battery in got a battery icon with low level and would not progress in power from there would not accept the charge . I charged with a new cube led usb charger and data cable overnight got the right results noted above but this time no icon just black screen I dont know what the power level is. I have tried three days charging nothing computer and wall. Tried to make phone vibrate and plug back in no. Windows phone one after mango, have lumia 710 zero problems removed battery twice to reboot phone twice in three years no biggie. Mango 7.5 on 710. want to use 800 as a data phone only would not trust it (mine anyway) for communication. Paid good price for it would like it to work again. Should I try powering it up for a few days? Oh phone always put on a surge protector as all my phones are. I once put phone under my pillow and a few hours later it booted screen came on. Have read people putting hair dryers on them I dont think thats the way to go got me here in the first place. very wonky phone it will and then it wont. I thought maybe usb connection damaged but obviously it is accepting some power and phone responding normally and readily to various key combo prompts but no boot and screen. How might this phone be repaired I would like to know what specifically could be the problem a base power or temp for reboot, what parts I could purchase (out of warranty) all parts inside were connected and looked pristine. No evidence of any heat damage. Used another Nokia battery for this phone new. This phone was let to totally power drain and what I have read that is not good for this phone. Maybe it is only accepting minimal power as before dont know but will try to charge another day to see if any activity occurs but would appreciate any help in zeroing in on what the problem or problems maybe, no software updates if no boot and it should do that if anything.
Sir,

Huawei P20 lite constantly vibrating after screen replace

Hi there,
Over the years i've done several smart phone repairs, screen replacements, batteries, new cases etc. All of them without any problems. A Few days ago a friend asked me to replace the case and screen of a Huawei P20 lite. Everything went fairly smooth, however after i finished replacing the parts and put the phone back together it does not turn on completely, only the charge light turns red and the phone is vibrating non stop while on charger.
Note: The phone has not been used +- 4 months before repair. When i remove the charger the phone dies again. Sometimes when powering up, the boot animation starts (max 2 sec) but then the screen goes black again (vibrating continues and charging led stays on). The battery was a real pain to get out, so it took some light bending to get it out. Not sure the battery is causing the issue though.
What i've tried:
- Charge the phone with different chargers/cables for 1 hour +
- Charge from low power charger for 4 hours.
- Leave the phone 2 days and try again
- Took it apart again and put it back together, exact same issue.
- Try to start the phone without battery/screen/camera's and other devices that are not mandatory, same issue persists.
- try to get in recovery etc.. no success.
Could anyone help me how to find the culprit of this issue, im really lost.. Any tips are much appreciated.
Thanks in advance!
check batery by multimeter first and if posible use other for test.
take tooth brush and clean all connectors in phone also.
Did u test screen before asembly it ? it was works ?
Hello I have the same problem and I fixed
Dear,
This is solved by changing the sense of the motherboard cable, incredible but True
