    Try holding the power button down. After maybe 10 seconds, the Home and Back buttons will begin to flash. Don't release the power button until they stop flashing. That should reboot the phone.

    Performing a factory reset using hardware buttons
    If you cant turn HTC*One on or access settings, you can still perform a factory reset by using the hardware buttons on HTC*One.

    Important: The Fast boot option in Settings > Power must not be selected.

    Press and hold the VOLUME DOWN button, and then press and hold the POWER button.
    Wait for the screen with the three Android images to appear, and then release the POWER and VOLUME DOWN buttons.
    Press VOLUME DOWN to select FACTORY RESET, and then press the POWER button.

    No luck with that either.

    I sent HTC one to service repair, and the problem came back!

    I think we should investigate the issue.
    For me, the first time this happened, was the night after I had updated the OS to Android 4.4.2 (Kitkat).
    After a hard reset, the screen was coming back sometimes (randomly?), like after keeping it in my pocket for a while, or by itself. After some minutes/hours it would revert to black screen..

    I found on the internet there could be a problem with a connector (like in HTC One X), but I didn't want to open and fix it by myself, since the phone is under warranty.
    As I said, I sent the phone to HTC service (in Italy). The company in charge for the actual repairing wrote they did "electronic repair", HTC service said the company in charge did just a check and found nothing wrong.

    After they "repaired" the phone (and I restored everything as it was using HTC sync manager), the problem has arisen the first time I left the phone uncharged (after 2 weeks, but I suspect it could be the day after). When I charged back and switch on, the screen was gone, once more -.-'

    I am about to re-send the phone for repairing, but how can I restore my phone WITHOUT installing Android 4.4.2 then? Just to give it a try, it might be it.

    If you have any similar experience please share.

    I love this phone, but GOD, 700 for these problems AND this SERVICE??!

    Hello guys, have never tried to help anyone online, but when its come up to the problem the first place I look up for help is forums like this one.
    Any ways had the same issue black screen buttons glowing, try to press down any combinations with power and volume buttons starts to flash, but still no results.
    Solution: try to put it under bright light and then press the power button then choose restart.
    Hope it helps.

    Hi all! My HTC one screen has been black on and off for about 4 months now, and I FINALLY found a solution... I tried everything but a hard reset (thank goodness), up until last night, and I'm so happy I stumbled on this. Ok, when your screen is black, you can take a bright flashlight, and at just the right angle pointing at the screen, you can see the icons (I learned this few years back with my incredible that got wet). Go to the display settings and turn up the brightness, and it should come right back to life. I was going to try to save my stuff, but tinkered around first instead, and I'm so glad I did- This worked for me and I hope it helps someone else too! Now if I can only figure out how this happened... Good luck!

    This is the solution. Shine a bright light on the sensor in the upper left part of the phone and the screen will come on. When it does do a restart. Your phone will now work, but this problem may return from time to time. The cause of the problem is a defective proximity sensor and it's fairly common among all makes of phones.
