What is happening - LG V40 Questions & Answers

About an half an hour ago my phone screen started seizuring, at first it was just a few waves with a darkened screen, so i restar it. soon it started turning static and occasionally going back to normal after 5 minutes of freaking out. I tried to reset the phone but i got met with another static screen.

i get same problem here
my phone static screen problem cannot stop.
plz help

Your will have to install the rom through LG UP if you know how to do it. Youll need the kdz file for the rom your currently on and flash it but if it still does it then youll probably need to replace the screen

what did you do *before* your diamond stopped turning on?? unless you had a completely unpredicted system meltdown of your diamond for injecting it with super high voltage. it is rare for it to not power off unless you did something ... so please elaborate so we can assist better.
Ok, yesterday i use the phone like anothe normal day, in the night i turn off the phone, and in the morning, when i tried to turn on, i have this problem, for example, when a tried to do a soft, hard reset, the screen is in black, when a conect the phone to the usb the screen is black, is, i left the phone alone, in 3 minutes the black screen again, i don´t know why.
any LED activity when plugged into USB?
I think it is a major manufacture problem
I had the same problem, taking out the battery waiting a while and inserting it back, will solve the problem for some time but it will happen again.
Finally I sent it to the HTC support center.
I don't understand why HTC didn't recall.
If you'll search this forum you'll see the same problem in different stages, some times it's a blank screen but the phone will ring and some are just freeze.
Hi, I've had my Diamond for about a month soon and it started earlier this week by not wanting to come on at all. Been taking out the battery for a few days but eventually got fed up and did a hardware reset tonight. Not long after that it just suddenly turned itself off and I couldn't get it back on again. I thought I'd pack it back into the box it came in and send it back tomorrow and took out the sim card. After that it came to life again.
Happened to get a call after that and that call was suddenly disconnected without any reason.
So I am not very happy with this phone at the moment. Would appreciate any advice or if you know for sure it can't be sorted maybe I should send it back and ask for another one?

Nothing, but one time the pc detect the phone, but later nothing.
No Led activity either on mine when it went dead.
When the Phone goes dead, try cooling the phone down as much as possible, and try starting it up again.....
There is a problem with the HTC Diamond in that it can cook itself (excessive heat), due to the auto over temp function crashing and not switching off the phone..... (That's what I have been told at least...)
I know over around 5 Diamonds so far that have had this issue, where the symptoms slowly get worse...
Have a look at this thread....

PLEASE P.M. me if you have any of the symptoms described in the thread...
I have been TRYING to get my Diamond fixed under warranty now for 2 months with little success... And I kinda need to know how wide spread this problem is to proceed any further.
could not turn on after blank screen ...
Hello,
I've had the same issue as rmorera, and after I hard reseted the phone all went o.k.. BUT after I reinstalled part of the small apps I use, the phone started to go off again. So, the problem seems to be in the software ...
I believe the cause might be the SRS WOW which I use. I installed the .cab, then the .reg file provided (ufortunatelly I don't remember from which thread I got the files ...). And shortly after, the phone stopped working. I uninstalled the software, and now it works! Could it be that the SRS WoW did this?
I tried to reinstall the SRS WoW and I found that if enabled for "Internal (Stereo)" instead of "Headphones" it gets my phone shut when the WM blanks the screen. If I select the "Headphones" options the issue seems to disappear.
Still, the SRS WoW damages the volume buttons action, but I think this issue is on another thread ...

My g1 has gone mad

Ok so like 10 minutes ago i was charging my phone..... all of a sudden my phone lights up and goes black, so i thought someone had called me and my phone lagged out or w/e and just acting weird so.... long story short when i press any buttons you can see it flicker on and off the lights that lite up the buttons and at the same time the screen goes from the lock screen to the time screen to the power off screen. never did that before... question is
short circut?
ROM?
please note that i do work with my phone in my pocket and i build homes so wood does press against the phone... but again, never had a problem before...
flash
I doubt that where you work has anything to do with it. I had a moto rizr. It took over a year at a shipyard for it to hit its last strides. I suggest rewipe and flash and see what happened after that.
If a wipe and flash doesn't work, I wouldn't even bother trying to fix it yourself unless it is out of warranty. Contact T-Mobile, and they should be able to set you up with a new one.
I say it a program that eventually became corrupted a flash will work.

Phone crashing while in landscape *update* now stuck on Loading... after stock ROM

I've done a search and can't find a reason why but a few days ago when i put my phone into landscape to text its crashing the screen.
I can type what i want and then slide the keyboard back and its sometimes on the screen but every so often it needs the battery to be removed.
Any help??
Thanks
It looks like your phone is having the same issue I was having. Basically when I put my phone in landscape mode the screen would go black and the phone restarted by itself. After I upgraded my firmware to R3A, the screen would turn black. My issue had to do with the phone's flex ribbon got messed up and you'll have to send it in to the repair center to get it fixed. Be advised that the part is backordered and you'll have to wait about a month to get your phone back. If you're lucky you'll get it back faster but in from my experience it was a long wait.
Good luck!
Thanks, I've tried putting the stock ROM back on but now its just stuck on the Loading... screen and i can't do anything, it wont go passed it

[Q] Help!!! Grainy green screen With lines during boot up

It started about 30mins ago, was on a call which the screen locks off when u on a call like stand by, but when ending the call the screen would turn on back no matter what. anyways i took out the battery thinking maybe the roms just buggy or the battery dead since it was on low. puttin back the battery the phone wouldnt turn on, took it out and tried again same result.
so i put it on charged nothing, gave it about 2mins charge it came on, but the boot screen with the X just had some green pixel dots all over and horizontal lines for about 3 secs then back to normal, but the phone wont boot pass that.
took out the batteries again, back in then try boot into fastboot or bootloader but nothing, just the boot screen, then the rom booted after waiting, took longer than normal. so i turned it off and try the bootloader or fastboot but it wont load just the rom, so i restarted to recovery mode from the rom it worked, turn off and try bootloader or fastloader mode they worked, now it seems all working fine, also my touchscreen is responding perfectly and the rom loading ok.
but anytime i boot the phone the bootscreen has the green pixels and lines just the same. im abit worried as i dont want things getting worse, is there anyway to fix this, is it some virus? could i just flush everything and start over???
any help would be greatful, thanks.

You guys think updating my radio from 4.06 to probably 5.08?
Almost similar with few different colors but I dropped my n1. It took me almost a day to see that the LCD was broken. Turn off the phone or screen and look in sunlight. They really were hard to notice and I showed to 4 different peoples whom all failed to notice until I showed them. Hope yours is just a minor software problem.
well i just check its not broken and it didnt fall from me so im guessing its software but im wondering if it can fix but i dont wanna flash my phone and things get worse or even brick my phone, so im asking before i try anything more.

Black screen during boot

I bought a used Droid Turbo 64 GB and for the second time I am stuck in a situation where the screen went blank and now the device won't boot. I get to the silver/blue "Droid" splash screen where it sits for a moment or so, then the screen goes blank. After the first time I wiped and started over, it worked well for three days. Now it happened again. I tried wiping cache, did not help. I was thinking I could reflash Lollipop and would not lose data this time but can't seem to find the appropriate file to flash. Can someone point me to it, or let me know if that's not the right direction to go? As soon as I get a replacement I am sending this back but would like to try and get it up and running for the next few days.

But is it wise to fix a device you are returning?

Just trying to get it to be usable until I can get a replacement phone.
While I was researching and posting here, I shut the phone off and put it on a charger. It said it was 61%. It got to 98%, I took a chance and powered it on and it got past the splash screen and went through an optimization of 63 apps. Finished and booted. Lasted about 10 mins then went black again and I am stuck.
I'm not sure if this is what your talking about but If you press the power button when it is in sleep mode and you see the clock and notifications but the background is black. If you pull up it should unlock the phone but everything goes black. That happens to me every so often. I reset my whole phone once thinking it was broken. All you have to do is pull down rather then up and the background appears and all is well again.

Thanks for the info but this phone is locking up. We turned off that mode. The screen does black after 1 min (in display settings). In our case, there is no way to get it to come back on. And during reboot, it goes black and never finishes booting.
You're best bet is to flash the stock firmware. http://rootjunkysdl.com/?device=Droid Turbo&folder=Firmware
i have the same issue, did firmware flash with fastboot and the fix with the verizon software with no results
