Have you tried factory reset. Or just download the stock Rom and use odin to reinstall.

Actually what I ended up doing was, powering down the phone and then powering it on. That seemed to fix it, but I'm concerned if it was a temporary fix.

It has to be temporary fix.. It shouldn't have done that in the first place.. Then again if it worked that's good.

you probably have some apps that is keeping the phone awake
or enabled the setting to keep phone awake when on USB
or you need to change the screen time out setting to something like 15sec

[Q] Blank screen after HTC Function Test Program

Hello to all, I read alot on this forum, but decided to register as I believe that there are very intelligent individuals on this forum.
Yesterday I tried the "HTC Function Test Program 1.03g" on my HTC Wildfire (WWE_2.22.405.1). I did this by calling the number: #*#*3424#*#*
I did a "Display Test" which displayed a white screen and dissapeared by pressing the back key. After doing that test I noticed the screen doesn't sleep, in other words the screen remains on with back lighting.
Today my phone paused and I saw a very colorful graphic on the display so I had to reboot / removed battery.
The screen was blank, after trying to remove the battery etc I managed to boot untill enter sim code but right after that the screen went blank again.
Now I have figured out that the phone is running normally, the screen is blank though. After reading in the forums I successfully reinstalled the RUU Ver. (RUU_Buzz_Froyo_HTC_WWE_2.22.405.1_Radio_13.55.55.24H_3.35.20.10_release_160191_signed)
But still blank screen. My feeling tells me that the display has somehow been disabled. I cannot boot into recovery mode (Volume-down+power on) as the screen is still blank. No matter what I do, screen blank.
The phone seems to still be alive.
Any ideas what I could try? I have done this test on another phone now, and the screen is staying on now, so Im worried if I reboot it, I will end up with blank screen.
Please give me some ideas on what to try I would be very grateful.

Sd-card was faulty! very strange!

HTC One X Screen won't turn on, touchscreen still work???

I have been using the HOX for over 2 months now but this morning my phone display suddenly doesn't turn on even the backlight key still on and touchscreen still work ( when I sweep my finger up the unlock sound still play, and I can even adjust the volume of the phone, etc... ) I have no ideas if this is a software or hardware problem and how to solve it, I'm still on Stock Rom, Stock Kernel,... Please help me
try to reboot pressing power button for 10 seconds, if it'll not work, it can be hardware problem, as i understood you haven't unlocked it, so you can send it to htc and they will repair it, or if you can, you can change it by yourself,
have you tried starting in bootloader and factory resetting?

Yeah I tried to reset the phone, ai first it worked. But when I turn the screen off and doesn't use it for a few minutes, the problem is back again, It's really odd, I have heard about lots of HOX Screen problem but I haven't seen this one before
So the screen works in bootloader?

Sometimes it does, sometimes it doesn't. Really weird, it feels like the phone has woke up but the display still "think" that it still in standby mode
Hardware fault for sure.
Same Problem
Hey, ive been using my international HTC One X for about two months too now and there have been no problems. ever since the update to 4.0.3 ive been facing exactly the same problem. The screen does not turn on a lot of the time but the touch is active. Have you found any solution to it?

I have the same problem now. Using it completely stock, the screen doesn't turn on. Well.... Except for the times I visit the Vodafone shop to get it fixed....
Their first reaction was a defect in the screen, so they ordered a new one. I brought it yesterday again and it is now in for repair.
I don't know if this will solve the problem. How did they fix yours?

hey guys
I had this problem a month ago, i know its frustrating.
anyway the only solution is factory rest from boot loader and flash RUU (worked for me)
the first time i had it, i did a factory reset, all my pics music were gone, phone went back to normal( stock, locked)
after a day the problem appeared again, second rest.
flashed RUU and the problem is gone. thanks god i have been using my HOX about a month science that problem and every thing is working great.
im sure its a software issue and I recommend every one to back up their files(pics,music)
just flash RUU and good luck
Lol, exactly the issue I had recently had with mine. Sent it backto htc, let's see what they would do about it.

My colleque has the same issue with his One X.
It started with suddenly everything on his screen looking "zoomed in", so everything double size, looking ugly as a mofo, and not usable. After locking the sceen and unlocking again, it was fine.
Monday suddenly also screen didn't want to turn on anymore. Did the hard reboot for him, and it worked again... Untill he locked his screen and wanted to unlock, same issue.
Also, that time when doing the hard reboot, screen didn't turn on at all. Did another one, and worked again.
He's now sent it in for repair, this definately sounds like ahrdware issue, even full reset through bootloader didn't help.

Yup, exactly the same problem I'm having, I sent it to HTC, they said they fixed it by replacing the motherboard, but now it is happening again, I will have to send to HTC again.
This just happened to my phone... Has anyone else solved it? Is reset and flashing RUU the solution?

I have the same problem right now.
It started last week when I was using Flipboard and suddenly everything started zooming in and stuff (same as mhulsegge above). It was resolved by locking my screen and unlocking it.
Last night, i've been getting the black screen when I try to unlock my phone. The touchscreen still works but the screen is just blank. It turns on if I keep locking and unlocking, but it's getting annoying.
My phone is an international One X (duh) bought in Hong Kong and I'm currently living in Canada so it would not be possible to send it back for repairs. Plus my phone is rooted and I am currently using the latest MIUI ROM (2.9.21). I have been using an app called "Sleep" which tracks your sleeping patterns. It requires you to place your screen face down on your bed when you sleep and the accelerometer will track your sleeping patterns and wake you up at the most optimal time. I assume that for the accelerometer to work the screen has to be on, so I am wondering if this can be a screen malfunction (overheat or overuse) problem since the screen has been on for so long (every night when i sleep for around a month).
Since sending it back is out of the question for me because of where I am living right now and I have voided my warranty, I am downloading other ROMs as we speak and seeing if it is a problem with my ROM. I will keep you guys posted.
-edit- I have tried factory reset and reinstalling my ROM (with a full wipe). Still doesn't work.
It´s probably not your rom since I use CM10 hand have the same problem and others have even been running stock and had this problem. The only one who seems to have solved this (at least in this thread) flashed RUU, so guess I´ll go try that now...
Would be great to hear if anyone else has solved it, and how!
edit: This has to be a hardware problem, if I push on the screen it starts working! Its like something is loose, and when i press on the screen it gets connected again.

Good tip, but I tried a gentle two-fingered push (zoom pinch) and the backlight turned itself on with very little pressure, certainly not enough to flex the screen. I believe that it is a state issue related to zoom, but will try again and report if the issue returns.
Screen black after replacement lcd display unit
Hi,
My HOX touchscreen was broken, the touch and everything was still working. I ordered a replacement lcd display Unit and replaced the complete display and touch. After replacement the screen is completely black but the phone still works. The touch buttons on the bottom still work and i can use the volume buttons. I replaced the lcd display unit very carefully and i am sure nothing is broken etc. So the touch is working but the screen is black. I tried 2 display units and both show me a black screen.
Does anyone know how to solve this problem? Did i forget to do something during the replacement?
Please, i need some help with this issue.
OneX has too much issue with Screen . WTF with HTC?

[Q] WFS touch screen not responding properly

Hi,
The touch screen in my wildfire s is not responding properly. Sometimes while using the phone, some touch feature gets clicked automatically, for e.g. when I am using the camera, the home button gets clicked automatically and it comes to the home page or some time the search window pops up automatically from no where. Rooting the device or putting a custom rom din't help.
Please help me to know whether I need to change some hardware from the service center or does this prob has some soft fixes?? Any body else having the similar kinda prob??
//Bubun
I've had similar things happen on my Wildfire S, but only under 2 conditions:
1. When my fingers/ the screen are wet. It tends to think i've pressed every button on the screen.
2. When the phone is overheated.
So if it's either of those problems, the first one is common sense to fix (dry yo' hands). The second probably means you're using too much RAM. Use a task manager to see if you have any RAM hogs.. It's probably neither of those, but it's the best I can do.
I've had a couple wfs that had problems similar to the ones that you are having. I just took the phone back because it was under warranty. Touch screen problems is a hardware issue that can't be fixed by flashing a ROM but sometimes it can but it depends. In your situation I would take the phone back if its under warranty. Is your phone new? When did you start experiencing this problem? Hope this helps.

I don't think that is the case with me as sometimes it happens just after the restart of the phone also. Some time it stops responding completely. But when I lock the screen and unlock it again through the power button, it starts responding properly. Can be a hardware issue. Is changing the digitizer gonna help? (I dnt have much knowledge about the hardware though.. )

Seriuos reboot issue

Since today in the morning I have been having several reboots when using the phone normally. I was using sedirom, never had any issues, just freezes, none other than that. How can I verify if my power button is f#+$%d up? Any ideas? Just flashed from odin the stock ics, and happened once... just touching the screen nothing else
Switched to cm11 4.4 ... so far so good, had a couple of reboots, haven't used the power button since, haven't had any random reboots since. I'm afraid my power button just screwed up I will have to look into a replacement soon. What a shame, ive been really comfortable with my glide. I guess its time to move on. The device itself is doing great except for the power button. Installed link2sd which has a widget for reboot options. Ill go from there.
Found this: https://www.youtube.com/watch?v=pQ-U-Q_NdOo I honestly dont think that would work but ill give it a shot. yesterday i cleaned the power button by opening the phone and removing the motherboard. It worked fine, but its happened like 3 times so far today. Has anybody here had the issue with the power button? What do I do? :s :crying:
Well my development Glide has the same issue. Sometimes it works flewless and sometimes it takes 3 or 4 times to even reach TWRP cause it powers off an on again. But I'm uncertain if it is the power button what makes you sure that it is not another defect inside?

Ive made several tests, even having a certain app to lock my screen and unlock it by opening the keyboard work great with no issues. When using the power button (sometimes), it turns off, reboots, and goes on a loop until I press it several times or hit the phone against my knee like pushing out the button, if you know what i mean. Yesterday I opened the phone, took out the motherboard, cleaned around the power button, and it actually worked fine, until like 10 hours after it happened again. And if i press the power button in a certain way like from the corner for example, it will screw up. Well i really could not explain it really well, thing is im 99% sure it is the power button
Any news about that? You said that you have opened the glide is it possible to replace the power button ?
Hm or we need to buy a e.g. screen broken glide and replace the whole motherboard? Would that be possible?

Turns out replacing the battery was the solution... wtf right???! I mean, I was using one I bought from Amazon, it was working great. Till the issue with random reboots came out. I did open the phone, cleaned the motherboard, and as far as Ive seen, yes you could replace the power button, however, after cleaning it, the issue came back afterwards. Just out of curiosity, I placed my old stock battery back on the phone, and never had the issue again. Power button is working fine, and never got stuck in a boot loop again... While I was investigating the issue, I came out with a dude on a video where he ¨cleaned¨out the battery contacts and it worked for him, thats why I used my old battery. And it actually worked. My phone has been good ever since I replaced the old battery. Not even one single random reboot again. Thanks for asking though.

Well let me tell you, it worked out for some time, but it is back. Got a couple of reboots today, I know is the power button since the shut down options came out after I tried to unlock the phone... This sucks. I cannot assure if it is the power button... It seems it is fine, but presumptuously most samsung branded phones have that same issue at some point. And the power button appears to be ok... sigh... Guess Ill have to start thinking which will be my replacement phone...
Today Ive made a hard decision. Im moving on from my old cappy. It had a good run, but the power button issues really got to my nerve. I believe I will go tomorrow to get a Sony Xperia L. Its been a pleasure guys, great device. Rolled me up for a good time. See you around:good:

Well I know have a new Sony Xperia L, pretty cool phone btw, and in regards to my glide, what I did was open that little bastard, remove the motherboard, completely remove the idiotic tiny power button from the motherboard. Tore it apart LOL. Place everything back, to the phone. Works! Then next step go to the play store download an app called: ProximityScreenOff-Lite, it uses the motion sensor to lock/unlock the phone, pretty much like a function found in CRdroid ROM. And if I need to reboot I have the Link2SD widget that allows me to reboot, quick reboot, or recovery
