If you're on warranty take it to Sony, if not.. take it to an experienced technician maybe something broke when you replace it.
Something went wrong when you opened it. If there was a problem with the screen it would work but it wouldn't desplay anything. For example the vibration, charging, led lights should work.
Warranty will not cover you so send it to a technician as said above
he vibrate when i press the button.Maybe i not connect display correctly.

Maybe, try to reopen it and see if there is any obvious reason for not displaying...
Where did you buy the screen from? Are you sure it is ok?
I currently have a stock HTC One in Canada on the Telus network.
The last few weeks i noticed the LED light growing dim. About a week ago the phone rebooted itself only to say it had an issue and that it was not shutdown correctly.. and asked if i wanted to report the problem to HTC.
The phone the froze with the Screen on but a black background.
After 15 minutes i powered off the phone.
At this point the phone would not power back on.. when i plugged the power in to the phone from the wall the phone would not indicate that it was charging via LED.
I tried booting no response.. no vibrating,.. just slight flashing lights on the Home/back buttons
I ended up booting up the phone by shining a bright light into the light sensor while holding Power and DOWN volume..
Phone has been working fine ever since, however still no LED.
I did a factory reset and still no LED.
Has anyone see anything like this?
I want to root and install Google Edition Android however if the hardware is faulty i dont want to risk voiding the warranty and being stuck with a faulty phone.

This has happened to me too. Just one day noticed no led light anymore. Strange thing to break down on a phone! Have you had any joy in getting a fix?

Unfortunately I have not been successful getting the LED back.. I am debating sending the phone in for Warranty work... or just sucking it up and rooting/flashing custom roms.
My main concern is that there may be a bigger hardware issue going on internally.
I'm really just trying to get a feel of how common this issue is..

Try this: in dialer type *#*#3424#*#* (3424 = DIAG), that will bring up HTC internal diagnostic, there's a "LED Test", select and run it to see if it's a hardware defect or not (you will get Orange and Green LED tests).

Thanks for the info.. Just tried it the LED test .
To my surprise the Green and Orange lights actually show up but I have to hold it to my eye and block out any external light to see anything.. kind of defeats the purpose of an LED notification light..
I guess the light works its just extremely DIM.
Any way of controlling the LED light brightness?

Don't know, but I just ran the same test in a very well lit environment and the Green and Orange LED are quite bright... I don't have to "go look for them" they pop out nicely.
Are you using a cover of any kind? Or maybe the LED has somehow shifted it's position and is being partially covered by the speaker grill? Hate to say it, but sounds like a hardware issue. Sorry
Hope someone else has other ideas.

Not using any case that would cover the LED.. that being said even with the Case off.. the LED is still very dim.

Shouldn't affect it. I've been using ARHD 9 through 13.3 and works with all of them.

I've ran the LED test, and all of them work. But they dont light up for notifications, and i have it enabled in the settings.

I have the same problem. Did factory reset two times. Red when charging, green when full but no flashing green for notification. I enabled it in settings.
Have you manage to find a solution for the problem?
Thanks.

I also have the same problem: when it is charging and when it is fully charged the light works OK but doesn't flash for notifications. But it worked OK some time ago. Actually, when I think about it, it seems that the problem started after I had updated to the current firmware: Android version 4.3, HTC Sense version 5.5, software number 3.62.401.1
It must be issue with firmware/software because LED test works fine.
There's another thread similar to this one and someone there figured out the solution - you do a factory reset but, when the phone reboots, you do not restore everything using your Google account. Go through the setup as normal (without restoring) and once that is complete then you can add your Google account details.
It means you have to download and set up your apps again, but it is worth it to get the LED working.
HI I had a similar problem I cleaned out the hole with a needle and all is well, pin came out dirty (the one on the grill dirt was blocking led )
I haven't seen this posted anywhere so I figured I would post for anyone having a similar issue with their One.
Recently my phones backlight stopped working. It would not work at boot or in the ROM. I tried flashing to stock and tried optimizing the proximity sensor, but no luck. It was clearly a hardware problem.
Not seeing any solution to this issue other than people saying it is the screen or the motherboard I decided to order a new screen.
Well installed the new screen, still no backlight. I was about to give up on it and just buy another phone, but I got the feeling that the light sensor may still be my issue. The backlight on the capacitive buttons would not turn on unless I helded down the power button to force shutdown. This meant the backlights for the buttons at least worked and something else in the phone was preventing them from turning on.
I decided to remove the light sensor from the daughterboard (opposite the power button connector). Booted it back up, and the screen came right on. The phone works great without it, other than auto brightness. The screen still turns off when against face during calls.
So long story short if your LCD and button backlights aren't working don't order an LCD or rule your phone dead right away. Open it up and take out the light sensor, it could be the culprit.
I'm going to order a new sensor and can update with results after installing if anyone is interested. In the meantime I'm using the phone without it, no hiccups so far.

hey
i'm having the same problem are you sure that it is a hardware issue and not the software issue my h/w buttons doesn't light at all and my screen stays black for some time after unlocking the phone it comes back but the brightness is too low
any suggestions would be appriciated
Mine was a hardware issue, the backlight did not turn on at all, even on the htc start screen. The capacitive buttons would only flash when holding down the power button. If ypurs is intermittent and your phone is rooted you cantry insralling an app fhat alows you to change the proximity settings, sorry, cant remember the name of the app i tried. If the app can't detect the sensor it is likely broken like mine was. If that doesnt work try a different rom.
If neither of those help it is likely a hardware issue.
i used the app both light senor and proximity sensor are working fine
any other tips that i can try

Sorry for taking so long to respond, just noticed your reply.
Did you ever get it working? If a different rom did not solve your issue maybe your sensor is just dirty. You could try cleaning it with a can of compressed air. Not sure how effective it would be, but it may help.
Hi @nsodmordex, my HTC One M7 is in the same situation as you describe, no backlight, but working. I'm going to try your suggestion of removing the light sensor, but I'm unable to find it, I'm not sure where the light sensor is.
Please, can you tell me which component is the light sensor? This is a photo of the daughter board:
htt ps://d3nevzfk7ii3be.cloudfront.net/igi/ALPJIMWqGsLwul5Y.huge
Thanks!
Found it... it's located behind the daughter board, at the two little holes of the front cover of the phone. I have removed it but no luck, the screen continues black, but the mobile is working good.
it seems a screen related problem, I'm going to try to change the screen and see if it comes to life again.
Drain battery
Hi all,
I also have this problem and found out that if I drain the battery completely and wait about 1 hour, it turns back on when I put the charger in the phone, if the screen doesn't turn on, drain and wait longer, if it does turn back on then power the phone. Do not wait till it has a little bit power because than it fails again and you must drain and wait again.
It works for me and I will make a video of it and post a link later.
Hope it works for you all!
Tip: use a led flashlight to see what's on the display

Than the lightsensor is broken, are the contacts on the back of the sensor 100% clean, in my case it was dust that created the error.
Is the display not broken?

The display is ok because I can see what is on the phone with the LED flash of a Galaxy S2 so I think that the display is not broken.
The backlight doesn´t turn on with the light sensor and without it either. But i can remember that the last time that it worked the Autobrightness was fine
Edit: I tried rebooting on fastboot and recovery via ADB and the screen is without backlight too
PD: Sorry for my English

In my case, if it worked it was ok also the autobrightness.
I think the sensor is broken and if you replace it the backlight comes back on (sensor is +- 10€ in holland)
Just give it shot
Have you tried the battery drain?
Hehe my english is also not very good

But as I read, if I remove the sensor and turn on the phone without it, will it work?
In this moment the phone has 0% battery and if I plug the charger i can see the red light and if i use a flashlight, i can see "the battery with the lightning" on the screen

No i dont think thats gonna work, push the power button (whitout charger) every time till the battery is really empty, than wait an hour.
If you connect the charger and the screen will not turn on, wait longer. a night is even better.
If the screens comes on then turn direct the phone on dont let it dim itself or else you can wait again.
This worked in my case but my lightsensor was dirty and after a cleanup it worked normal and it stil works.

Okay, thanks, it worked once, but with the phone turned on and the backlight working, if the screen turns off, the backlight runs away again.
can you repeat point by point what i need to do?
when you say "drain" the battery, you mean leaving the phone on till it turns off? then what should i do? wait an hour and plug the charger to see if it works right? okay, and later if the phone turns on what i need to do?

By 'drain the battery' i mean continuously turning the phone on with a empty battery till it does nothing, not even vibrate.
It must be so empty that the phone not knows its a phone.
And yes if the screen comes on just power it on, thats it.
1 drain
2 wait
3 plug in charger
4 screen comes on
5 turn phone on
6 done
1 drain
2 wait
3 plug in charger
4 screen stays off
5 drain and wait longer
that are the steps that worked for me
Thanks @Dippie83 , it "worked" draining the battery and waiting forma a night to turn it on but when i turn on and i push the power button yo lock the screen, the backlight stops working
Any idea?
Hello fellas,
I replaced my note 5 lcd before 4 days it was working perfect w/out any flaws but it suddenly went black while using it was full charged while it happend. but i can receive calls texts hear sounds. I tried a youtube fix by holding Vol down+Power!! Yes it does reboot the phone but whateva happens lcd is black, even i tried to flash stock rom also its succeed!!
I dont know what the problem is but my lcd was broken before, while in that stage it cannot boot or receive calls there was only a solid blue led.
But in this case i dont know what the problem is and i think you might help me figure out.
Thanks.

I had the exact same problem and unfortunately the phone had to be replaced under warranty so if you don't have a warranty on the phone then immediately contact whoever sold you the screen and get a replacement since that one's broken. It's not going to come back no matter what and it was probably a cheap knock off which is all I keep seeing all over the place but try anyway because they aren't cheap at all!!!
Sounds like when you had the LCD replaced they didnt do the digitizer ( that is the component that converts the signal to pictures for display on the screen) usually when one is damaged they are both replaced at the same time

I think you're a bit confused on what a digitizer is... It's not for converting pictures it's for dealing with the touch part of it I.E it senses where your fingers are on the screen.
phone seems to be working, it turns on, vibrates and the touch is working
but., somehow the screen is black!! not turning on at all.. tried everything (combinations of buttons, disassembled the phone and reassembled it)..
any suggestions guys?

Shot in the dark here. If you're getting vibrations and response to touch, my best guess would be that the screen itself is damaged. May have to get a new panel for the device. I wouldn't THINK it would be software related, but for the sake of ruling things out, what software is the device running? Custom ROM? Stock build?
EDIT: It could be a simple thing like a loose or disconnected ribbon cable inside.
stock,
it actually happened after a reset (and shipping by USPS)

This is the phone where you hit factory reset, threw it in a box and shipped it while it was resetting?
Probably the screen was damaged in shipping.
