Hi all.
Lately I'm facing a strange problem with my device.
when I navigate with it in a sunny day,
or talking on the phone while charging,
the devices gets hot and the screen goes down.
I can hear that the device is working and the buttons is working, but the
touchscreen is 'dead'. its all black.
Even a softreset won't fix it, the device goes up without the screen.
To fix it I need to pull out the battery for like 2 minutes untill the device gets cold.
is it hardware problem? Anyone else experienced any of these problems?
Thanks!
...ehem...
try to charge it via USB and not a car charger. Is there any difference now?
IMHO you should replace the device
the same problem
Hi
I have the same problem than you
I can use my Polaris in my computer with MyMobiler application but the sceen it's always black.
Sometimes when I do a Hard reset and press button left side it's OK but after some days it's comming again.
I think is not a hardware probleme but software problem.
Do you have resolve your probleme ?

I haven't resolve the problem yet.
the screen getting black is due to the nature of how a display works. i dont know of it actually damages the device, but i strongly believe so.
the working conditions of the device are written down in the manual, if you exceed those they might not replace your unit. this of course sucks, but it *is* written down to not expose the unit to direct sunlight.

I didn't know about the exposing to the sun ...
well, I hope it isn't got damaged badly.
thanks.
As I said, I'm not sure about the damage part, I could be completely wrong. I just think it *could* be...
If it doesnt change and the device gets unusuable all the time, I'd suggest you send it in for a replacement. Maybe you really got a bad unit, who knows.
Edit: I just thought of stuff which is usually written down in manuals and the glovebox problem popped in my mind: devices stored in the glovebox of your car are breaking down because of the sheer heat which builds up when the car is standing in the sun for a long time. All sorts of displays usually break or get completely black until the unit could cool down again... And in the glovebox they werent even exposed to direct sunlight, its just the heat...
hello. I have same problem. But i can't catch situation when it appears. I think, the sun is not an main culprit, because my phone goes down, when i
playing games in the room! may be it's overheating, but cooling doesn't help me.
To fix it, i do several soft resets (sometimes more then 300 ). Sometimes one reset helps, sometimes no. I think, it is hardware problem. Also i have problems with my camera (colormess). May be they are connected.
I will try to send it to service.
Hey, i put my device into refrigerator, and screen is working . I have tried to reanimate it since yesterday. Battery unplugging didn't help.
F*******K!!!
After ten minutes in the room with temperature near 20 C it's black again.
Can be problem with temperature sensor?

Don't put it in the refrigerator without putting it in a plastic bag or something. Moisture can kill it.
i put it into plastic pack.
But i think, that I'll kill it myself by throwing in the wall
Hm, question:
Where does temperature sensor dislocated? In battery or in PDA?
Well,
In the lab they told me my Board damaged up.
total-lost
What kind of damage?
this problem i faced it two times ,one of them when i put it inside my car and the AC was runing (cold) and my screen became black
and the other time it happened in a hot condition (also in my car)
realy this is very strange
and the solution for both to remove the battery for a while

I've tried various different ROM images (including the excellent Dr.Gonzo), and I have this problem with all of them.
When I'm using the phone either with the keyboard in or out, the screen just switches off randomly. If I wait a few seconds (possibly the backlight timer length), then it comes back. Mostly... Othertimes I have to wait a lot longer, but it does always come back.
A reboot sometimes fixes it, but not always - does anything survive a reboot or battery removal?
Anybody else seen anything like this? I have seen a lot of threads about the screen staying on, but not off.
Of course, it could be a hardware fault, but because it's intermittent, it's hard to prove.
Mike
same problem
If you shake the phone can you re-produce this problem? I've never not heard of this being affected by software - you might also want to ensure you're not overclocking it.
Nothing is removed when you do a battery removal or reboot, ensure your connections are all tight and make sure the SIM pins are all making contact and the SIM door closes, apart from that it sounds like a possible bad LCD ribbon.
Shaking it doesn't reproduce the problem.
Once the phone has started doing this, it happens everytime you press a key.
Seems more like a memory leak to me since it always seems to happen after a while of web browsing/email use.
So actually, it looks like it might be a hardware fault.
I think it happens when the device gets warm. After a few minutes with the screen on, keyboard lit up, wifi on, the phone gets pretty warm and that's when the screen seems to go black. Leave to cool and all returns to normal.
Mike
Same issue here, but the screen does not acually go black/blank it just seems that the screen backlight does not turn back on from a standby like state, the phone itself functions but just not able to see whats going on on the screen.
(keyboard lights work fine and come on when expected)
Not sure about the heat theory as it happens (to me) most often right after a call, anything over 30-50 seconds and the backlight problem occurs, when it decides to work again is a matter of luck.
As said before because it's intermittent, it's very hard to prove.
Has anyone who has had this issue, fixed it with a hard reset ?
Very strange ... but also getting very annoying now!
i got the same thing. took it back to warranty and they said nothing's wrong with the phone but i still get this.
I experience the same problems.. it happens pretty random, but every time when you hit a key. I have set all timers to never but the problem is still there.
Running Gonzo 1.1 at the moment, upgraded from guava.. but that didn't solve the problem.
It is getting so annoying now that I am about to throw the s710 in the dustbin
I have had the same problem!
I have turn it back to my provider and no problem now.
i have the same problem with my VOX
apparently, i can still receive phone calls, and do whatever i want with the phone,
but the screen just stays black, its like if you have unplugged your monitor
since i dont have a htc center in my town or anywhere else nearby.
does anyone know a way on how to open the phone, change what need to be changed and correct the problem? im all up for testing if that would resolve this annoying problem :s
cheers everyone
there is a dismantling manual somewhere in this forum. search.
i don't think taking it apart would help you because this is not a physical fault that you can locate.
and i learned that mcel is the retail seller of vox in mozambique. they should be able to help you with service. else just send a mail to htc support and they will guide you.
yes, mcel are the retail sellers, but i tried to go there, and there are no specialists on htc's there,
the thing is, i didnt bought my htc from them, so i can't go there and change for another one
but tks anyway
no problem
but do try to contact htc support by email. they might suggest a way.
I'm having exactly the same weird problem and I think I found some pattern when it occurs. Well, the thing is that in the bright day or in a room with lots of light it works just fine. In the darker conditions… well… not so fine. It seems to me that this screen blackout happens whenever the keyboard light is on and screen changes to full brightness (in the dark, because of the light sensor). In the daylight, keyboard light doesn't turn itself on, so s710 works. I don't know much but this definitely isn't some bad contact problem. Maybe some battery problem, but I doubt it since I can receive phone call in this condition. This started to happen after I flashed this Windows Mobile 6.1 ROM from HTC (I have original S710). Flashing Dr.Gonzo's later on didn't bring any luck either. I believe that some power control SW is the main culprit. I've read that many people mention some Tornado Power Control app. Does anybody know can this application be permanently disabled or removed?
are you trying to say that by desabling the light sensor, the problem might go away?
i would also like to know if it possible to have the baklight on the lowest possible brightness forever, because it seems, on a low brightness the problem might go away

I also have this problem with the lightsensor turned off. And also at (as it seems) random moments.
well, even with the light sensor turned off, the problem persisted.
i got my phone to a repair shop of htc's, and they figured out the problem
my phone is now 100% thankfully, the repair man told that the problem was because of bad or malfunctioned circuits, he exchanged them with new ones, and the problem went away,
dont know wich circuits exactly, and he didnt want to tell me, but i suggest anyone having the same problem to try and do the same
probably its a hardware malfunction with these VOX,
its possible since so many times before i've heard about malfunctioned pieces coming out in large quantities for sale.
anyways, cheers everyone, and good luck Portugal in EURO!
I have the same problem. I just noticed that it usually happens when the phone is warm, so if you need to do something on my phone just... take some ice from fridge and put it on back of your mobile. I cant see any more solutions.
Please someone help us!
Update. Problem Solved
Just thought I'd update this thread I started.
I sent the phone back to my dealer (Grapevine in Poole,UK).
A week later, I got a brand new one back from the HTC repair centre.
So far, so good. Looks like the problem's solved.
Mike
Sam problem here,
i called with HTC and they sent them to there repair centre.
Hi people,
I have a question, I've been reading these forums a lot but now I have a problem that I don't really understand:
My HTC Trinity that has served me well does not want to boot at normal temeratures 21C - 70F. The akward thing is that if I put it in the freezer for 10 mins, it starts working , doesn't get hot. As it reaches 20+C it freezez or doesn't want to wake up from sleep anymore.
Any ideas as to why this happens it's clearly a hardware fail but what part of it ?
any help would be greatly appreciated.
Maybe it's the battery......did you tried it with other batteries....?
It maybe that you have a poor connection within the phone being affected by thermal expansion. Might also be moisture condensation in your phone (made worse if repeatedly placed in and out of a freezer) that requires drying out.

I'm guessing it's not the battery as when I put it in the freezer I take the battery out. Also, while the phone is off the battery charges normally, without heating up or anything.
The theory of a faulty contact makes more sense but then which one ? I do now have a star shaped screw driver with me (I'm travelling for the moment) but I'll try and open the phone once I get back to a more tinkering friendly environment.
I have put it since in a drawer and it has been waiting for me quietly. In the mean time I bought a Sony Xperia X1 which is an excellent phone. I would still try to fix my trinity, I'd use it exclusively as a GPS if it works.
Any other theories as to why this might happen or what should I do to fix it?
Thanks guys for the useful replies !
When issue occurs will it power up plugged into charger?
As BundyR stated there is a poor connection somewhere. Also known as a "cold solder joint". The trick will be having device apart but still being able to power it up at the same time and start poking around with a toothpick and a magnifying glass starting with the battery contacts and moving on from there.
good day.
Hi,
I have a question regarding to a digitizer that suddenly started going on the blink, meaning sometimes it doesn't work at all. The screen works normal but it doesn't respond to input. If it doesn't no amount of restarts will help. But if I let the phone turned off for a night, in the morning it will often just work.
I disassembled the phone and checked that the connector was properly connected and it seems to be (I took it out and put it back in). There is no obvious damage on the phone.
I was wondering if there are any known causes for this behaviour. I could just order another digitizer and install that, but since there is no visible damage, I'm a bit worried that it'll just be the same problem. Could it have something to do with the battery? I still have the original and it's not exactly great anymore. I run Shantur's CM11.
Cheers,
Marc

Hello together,
I have a Z5 (6653) that didn't start anymore and got extremely hot while charging. To be more clear: after connecting the phone to the charger the red LED turned on, then after about 10 seconds later it turned off again. From this moment on the phone's back started to get extremely hot. The source of the heat is about 1cm right and 1 cm down to the back camera (so you can say 1cm diagonal from the camera to the phone middle). Because of this I doubt it has to do with the battery as it should heat the lower two-third and not the upper third of the phone. Maybe the processor is at this place?
I tried to connect the phone in flash mode with the PC and it connected, but disconnected after a few seconds, probably because battery was empty. I repeated this procedure (connecting to charger, disconnecting, reconnecting, connecting to PC) a few days and suddenly the red LED kept on and the phone didn't get hot anymore.
So I charged the phone fully and wanted to start it, but the screen won't turn on anymore. Connecting it to the PC and the Phone drive (MTP) is displayed but empty, because you need to unlock screen. Also I hear the connecting sound of the phone and touch feedback sounds.
I tried the following things:
Xperia Companion Repair
Flashtool flashing newest ROM
Flashtool downgrading to 32.0.A.6.152_R5B (LP ROM)
Nothing helped. Well, the idea it is an hardware issue might be at hand, but maybe there is something else I can try first?
And if it is an Hardware issue, what is the cause? The Display itself? Then why was a single point at the phone back the source of heat and not a large area on the phone front?
A short summary:
Phone gets hot while connected to charger
Battery won't charge (LED indicator turns off after few seconds)
Source of heat is 1cm to the right and down to the back camera; after 2 minutes whole phone is hot and you can't recognize the source
After days of repeating the action (connect to charger, disconnect, connect to PC, connect to charger) it suddenly charged the battery and didn't get hot anymore
Display won't start anymore; still responsive
Tried Xperia Companion Software repair
flashed latest Stock ROM
flashed Lollipop Stock ROM
Phone has locked bootloader and is/was not rooted. I'm grateful for all help!
I guess its a dead screen maybe u droped it and the pins of the screens got ejected from the motherboard.. Ignoring the fact that it was empty of charge and you charged it.
From what i understand that the phone is working but there is no screen.
The best thing u can do is to check a hardware store that is capable of diagnosing the issue.
Im not helping here i know but wanted to share my thoughts..
Gd luck with that.
Thanks for this anyway. But phone didn't drop.
The fact that the phone wasn't charging and got hot instead at the beginning is very irritating. Especially that it wasn't the front but a point at the back near the camera. Is there a way to check if it's a Display issue and not a Mainboard/Processor/other Chip issue?
At least in Germany are a lot of stores that aren't too competent at all. But nobody would tell you, so its very helpful to know as much as possible before going to a store.
I think it might have something to do with the gpu inside the soc? The heat might have burned something inside the mainboard (how hot was it btw, like running intensive apps or even hotter than that?) Another thing that might have happened is the display cable is loose.
I've seen some Z5's screens and they're not that easy to die.
The best thing I can suggest is that you repair it in a trusted shop that lets you observe the repair procedure directly (open the phone, take the parts out, identify the problem).
Good luck with your phone.

I never played any game so it is hard to compare, but I never had a phone in my hands that got this hot before. You didn't get instantly burned touching the phone but it was already inconvenient hot for your fingers/hand.
There might be some trust able stores to find, but I doubt somebody will let you observe it, not even Apple store does. If you see the trick of how to repair it easy and fast, you might do it yourself next time. And it is also a question of the price. If I can buy a used but totally unharmed Z5 for the same price, why should I let it repair?
As far as I could see in Germany repairing Display starts at 99€ for the Z5. Buying display with adhesive would start at 49€. But if they change the Display and it's still broken you have to pay for the Display and also for the mainboard i.e.
Hi All
Has anyone had any issues with a black screen?
Everything else works like incoming calls and notifications but the screen it totally black!
Woke up early hours last night and noticed no AOD so tried to turn my phone on but the screen was just dead. Tried the volume and power button but still no joy
Power it down completely then plug in the charger.
If nothing shows on the screen it sounds like you lost some significant hardware... maybe just a connector.

Same happened to my SM-N9860 unit when I woke up today. I about to unlock and the display suddenly went black screen. Did everything but no luck. I am also sure it's the display that's f***d up. The phone is still working - I can still access it in Dex and Link to Windows. This is my second Samsung phone with f**d up display for unknown reason. This is crap Samsung. Not expecting for this from an expensive flagship smartphone. I swear this is the last.

By the way, how did you fix your phone?
I tried searching it on the net, seems a number of Note 20 ultra units are experiencing the same.

Seems that display replacement is the only fix.

Poor parts QC.
Samsung will substitute components and smaller chipsets in the middle of a production run. This can lead to unpredictable behavior especially after firmware updates... or outright failures like this.
Not reassuring especially with a flagship phone.

hi im facing exact same thing in my N986 B Galaxy Note 20 Ultra. I had 10 percent battery left. i had put phone on charge and saw after 20 minutes and tghe screen was black.
Now its blackscreen can connect with tv via hdmi dex mode
but phone restarts after 10 minutes.
the touch seems fine as mouse function works phone is on but no display
can you tell exactly what you did when your phone revieved after one day
did u keep it on. charge all tiime tried reset or removed charging
or nothing and tried after 1 day
Edit After 24 hours of tapping slappingrebooting installing stock firmware. my display came back alive.
last thing was i was using phone in dex mode and trying to open close camera app rapidly by direct touch on screen. i dont know what worked but it saved my 300 dollars of screen replacement
I have exactly the same issue.
I was typing on whatsapp when suddenly screen get black. It was on friday morning. Notifications were ok, voice commands too. Touchscreen ok, I could use it normally when using my TV as screen with HDMI cable or with my notebook, when connected to windows or even Dex.
One day earlier I had an issue with the new magisk update. I freeze magisk manager wich was force closing but later, I managed to reinstall with dex and was working fine. Not sure if it's related.
I already flashed fresh stock Android R rom, wich I thought would solve any issues related to magisk or any other software issue.
24h after flash stock rom and keep force rebooting and taping, and my display is still dead.
Tried to tap, slap, shake (I can her some noise next to camera module when shaking, is it normal? I took off S-pen and microsd tray to see if it was the cause, but the noise still persists). No damage, water, or anything else. Only 2 months of use.
Display is still dead.
I'm draining battery now with some apps that also vibrate phone, to see what happens when full drained.
I live in Manaus/Brazil and repair centers are not working until March 23 because of Sars-CoV2. And my knox is tripped. It would cost a lot If I have to replace display or even the phone, since they probably will say it's no longer covered by warranty.
Any tips are welcome.
Thanks in advance.
Hope I have that lucky as well.
It happened to me again today. Surprisingly, a strong knock at center of the screen revived it again.

Hardware failure. May be a loose connection, cracked solder joint, trace failure on the mobo, or a bad component.

Not good if there's a recall... crap QC is getting to be a bad Samsung habit.
Those of you with BSOD issues: Did you have intermittent wifi connectivity issues as well? My N20U had the 'connected to wifi AP but no internet' for the last month. Then today after unplugging the OEM charger, checking charge level, never picking the phone up from the desk, and returning to it 30 minutes later the BSOD had hit. No amount of hard restarts or waiting fixed it and it had to get shipped back. Just wondering if there is any correlation between the wifi issue and the screen going out, and if people should start sending their note in ASAP if the wifi problem occurs before the screen goes?
hello
i had the same problem (didn't have any Wifi issues before)
and after the screen went black for 2 day , it came back and worked for a few hours.. then went off again and Never came back
i tried everything, resets , cables , connecting to Dex or Hdmi , updating.. but Never worked
i went to Samsung and they said screen must be replaced ( will pay for it as i am out of warranty)
can you tell me what have you done or if anything worked for you?
My screen went black after a screen replacement. Only the front glass was broken not the digitizer or actual screen. From what I can tell it's not just the screen that's dead, it's the digitizer too. The S-Pen board underneath it all isn't even registering. When I plug it in the computer doesn't see it so Dex won't connect and there is no signal for HDMI to work. Had the USB port replaced just to be sure it wasn't a bad port.
It's like some one took the graphics card out of a computer and took the touch screen monitor. The phone still gets signal. It connected to my smart Fossil watch and I could answer calls and texts.
But the phone is 9 months old. And from what I've heard from parts distributors it's not the screen that's the issue. So now I have a new motherboard. Now I have to figure out how to program it....
