(HELP) second screen went off with main screen too - LG V10 Q&A, Help & Troubleshooting

First, sorry for my bad English!
My V10 H901V20L now the sencond sreen turns off with the main screen too. Means when I turned off the main screen, the second screen went off too, and I can't do anyting with the second screen too. I have tried so many ways ( like turn OFF and ON again both in Settings > Display > Second Screen, flash many difference roms after 4wipes) and it doesn't work.
I have searched in forum but seem like noone have a solution for this issue.
Can anyone help me pls!

I have followed this thread and enter "signboardtest", but seem like its not a solution for me.
https://forum.xda-developers.com/lg-v10/general/configure-test-screen-root-required-t3253752
And I have tested my proximity sensor, it works nomarly. So I can't find out what is the problems with my V10.

Can anyone help me pls!!!

I had tried so many ways. I flashed many roms .zip thru TWRP, and up rom .kdz ( and .TOT) thru LGUP. But it didn't work too.
And I don't know that is the problem with the hardware or softwware??? Cause the second screen works perfectly when the main screen ons.

Weird if you restored it it should work fine maybe you should restore it and take it in for warranty problem.

Sorry. Can you expland more...

I solved this problem by checking PINs on mainboard for the second Flex Cable for LCD of LG V10, see the video, READ comments here https://www.youtube.com/watch?v=hpeVAqgU94s, so in my case one of three PINs was folded little, so one PIN contact didn't touch the second Flex Cable and this caused the problem...

Hi, that's just the biggest problem, because the imei number is in the motherboard they simply don't sell them, so I bought a second hand phone with a broken screen and made one phone out of two.

Can you tell me more about the rom you are using.
It might not bee the mothelboard. Had this problem for a few months until my screen just went black one day!
Had to change the screen cable. It's a design flaw, each time you open the phone the cable gets scratched and soon the wires get clipped. I bought a new niki100 flex cable on ebay and open the phone and replaced it and put a small extra tape over the cable to be sure it would happen again...
problem
there is some version of software without the preliminary calibration of the touch screen of some time I hit on so... perhaps somebody will give bearings... thanks
placing a file name welcome.not on sdcard should bypass the welcome thing
hi, i'm new her.
but i had this problem to.
i bought an touch screen on dealextreme.com
it works great!
sorry for my bad english.

Happened to a lot of people. It's a hardware problem. You have to send it to Asus for repair.

I don't think the camera needs to be replaced. I think it's just a loose connection. You can do what you want with it. It's yours.

Vibration issue after last update

After last official update (7.3.2.0) on Redmi Note 3 Snapdragon I got issue with vibration.
Button and keyboard vibration randomly stops working 5-10-15min and then works again.
Anybody else?
Nobody else have this issue after last update?
it can be an update issue?
I also face the same problem. How can we resolve this?
My mobile vibration gone completely please help me
Thanks
Issues with official updates, are better discussed in miui thread, I guess?
Think your problem is the same as mine. Motor stop working randomly and start doing is job again in the same way.
Thought was a software problem, realized is an hardware one since i noticed that, when he stop vibrating, if i shake the phone, hes starting again.

You can send your phone in a xiaomi center. I saw you are from india, so you should have no problem. I'm from italy, this means i've to sent it back to china and wait a life to get it back. This is why i didnt resolved the problem and i lost interess on it
Think i'm going to wait the expire of the warranty and try to fix it by my own: i saw some videos and already tried to open the device, it shouldn't be difficult

No, the problem was because of loose connections so I reconnect the motor strip and also put a piece of paper inside the motor slot and tighten the motor. Now it is working fine.

I opened up my phone.
If you are not an advance user or don't have experience how to deal with phone hardware, I recommend you to go o service centre.
Otherwise you want to do yourself then first of all you have to check that if the motor is working or not. If the motor is working then you have to check the connection points the problem with me was because of loose connections and the motor was not tighten. Just check these points and you are good to go.
PS :- I always recommends to go to service centre because opening the phone voids the warranty
This is my situation.

You already tried wiping and several roms, so it is definitely not a software issue. If it was software the screen would have worked with at least 1 of the roms you tried.

Guys HEEEEEEELLLLPPPPP!!!
I have exactly the same problem! Surely someone knows what could cause this? Why does the backlight go off with the main screen??? The display is working, because if you shine light into it, the date/time/notifications are there it's just that the backlight is going off!!!! Surely this is software?
I've factory reset and it made no difference but that doesn't roll back to LP... I just upgraded this phone to the latest software when I bought it so don't know if it had this issue from new.
Sorry to take over the thread, will delete and start a new one if people would prefer.
Don't see how it can be hardware at fault???
Thanks in advance for any help?!

Unluckily, I got this phone from my friend and it broke after a few time, so I can't send it back to my friend and have to find a solution.

That's bad for you... unlucky.
Can you recall what (if anything) may have caused it to stop working? I'm wondering it mine went bad after LG bridge software update and restore from previous V10 (H961N).
Sent mine back and got another coming this week.. fingers crossed this time. Might update it the same but maybe not restore? or not restore settings at least?
Got my new one. Working fine except it's maybe a tad dimmer compared to my previous V10s second screen. There's definitely variation as it won't go off with my finger over the proximity sensor whereas my brothers one does (this just dims right down). A piece of cardboard or paper shuts it down. But most importantly, it does go off in my pocket... or else the wifi, sound, flashlight etc would be getting switched the whole time.
I solved this problem by checking PINs on mainboard for the second Flex Cable for LCD of LG V10, see the video, READ comments here https://www.youtube.com/watch?v=hpeVAqgU94s, so in my case one of three PINs was folded little, so one PIN contact didn't touch the second Flex Cable and this caused the problem...
