Well it certainly has to mine.

I've flashed the official JB rom as well as the latest firmware as provided by orange as well as running the OTA update provided by them immediately after restarting.

Immediately the phone is behaving better. Under JellyBam I only had occasional issues with graphics corruption and the power button refusing to wake the device. Under JB Remix the situation was MUCH worse with the phone refusing to turn on almost every time I sent it to sleep and graphics corruption a regular occurance.

Now that I have returned to the stock ROM the phone is performing much as it did under ICS, I have however noticed very minor graphics corruption still (and once now in recovery on the background logo which I have not seen before)

However the handset is now once again useable and wakes from sleep with the power button every time without fail.

I've done pretty exhaustive tests this evening of all of the apps that I use regularly both on battery and whilst being charged.

It is also worth noting that the only time I have seen this graphics corruption on the stock ROM has been whilst the handset has been very cold which is in line with other things I have read in this thread. (I am currently on Vacation snowboarding in the Austrian Alps and its -6 outside!!)

Once I returned to my apartment and the phone reached normal room temperature then all has been good as gold.

We are currently working on an Android release of our Miniclouds product at work and have been working very closely with HTC / Samsung with regards some issues we have faced with the latest generation of mobiles When I return to the office next week I will have my developers raise this with them directly to see if they can shed any light on what the issue may be.

It strikes me that the issue may be to do with the Kernels that use the Nvidia chip for graphics processing as the issues are very similar to those we encountered back in the day with early generation PC Nvidia cards when their memory registers were incorrectly accessed by some of our applications.

In the meantime, for me at least, this has made my handset use-able once more. (Although having to deal with all the bloatware shipped with the stock ROM is something of an irritation) I'll update on the situation if and when I hear anything further.

This thing happened to me as well..and it happened after I went back from vacation in france where the temperature over there at one time reached about -2 Celcius or something.Now im back in my country where temperature is 30 Celcius at average and thats when my phone went weird.Ive contacted HTC and they'll come and pick up my phone for service.

Could it be the change of temperature causes this issue?
[HTC One X] jelmer-p:
It could, I had some trouble with temperature, my hox was gettkng very very hot at the time. Soon there was the flickering screen failure and it gets worse over time.

But according to what I have read and a lot of people with this failure, is that the main problem is that there is something wrong with the motherboard vs video and it's messing your screen up.

I've re locked my bootloader and send it in for reparation. I got my phone back with a new motherboard and it's gooood now.
[HTC One X] blagger81:
I got this problem too, i just replaced my lcd as my last got smashed. Also has to solder on a new replacement fpc connector for the lcd as that broke. Finally got my lcd bk on and working only to find that it started to flicker, the brightness control didnt adjust also had artifacts / disolving screen and then black. Also when it did come bk alive, it would stay black black after trying to wake the phone after sleep mode.

I thought i could of been my soldering of the fpc, so took it off again and gonna clean it up again but after reading here thats not the case. Seen a post in this thread of someone wedging the chip with something so i might have a look around there as maybe use my hot air station to reflow the chip as i get the same style of issue from an old mxm nivida gfx card where its keeps needing reflowing.
[HTC One X] reslan_912:
possible solution

As all users above said its related to temperature. i managed to fix it like this in the attachment pictures ....see the tegra chip is now cooler than before and it turns on for about 2 hours straight before the problem come back again,so after it turns off due to high temp just turn it off enough to let the chip cool down..then again on for 2 straight hours...thats my temp solution
[HTC One X] schlibm:
Common Problem!

I've had the same issue. Started in January with flickering screen and then the issue with the screen not lighting up. Took screenshots which were always clear as a bell like there was no problem!

Called Orange and they asked me to send it in for repair, then it went ok! Didn't send it off, worked well until about a week ago. I sent it to Orange (now EE) on Saturday and apparently its repaired already.

Hope I don't get the same as other users where it starts again soon after...
[HTC One X] BogiYear:
Because of this issue I sold mine on ebay for 'spares or repairs' as it was rooted and I couldn't be bothered to fight HTC over warranty.

I got £136 for it. I now have a Nexus 4 which I'm very happy with!
[HTC One X] ludskyrider:
Same issue for my wife's oneX

Never be unlocked neither rooted nor flashed

It's an orange rom updated by OTA

First it was hard to wake it up and after a week, when i press the power buton, the screen stays black, just the bottoms butons are lighted...

The problem still be there after 3 hard reset

Send to HTC this afternoon
[HTC One X] amino1:
hi, it look like you are close to a good solution, how about puting colling past and piece of copper, that will realy cool it, give it a try and tel us the result. good luck
[HTC One X] blagger81:
Ended up sending my one x bk to get repaired and got it done for free
[HTC One X] joker79:
Same problem do you fix your device????

Same problem do you fix your HOX??? If you do please tell me how to!!!
[HTC One X] joshua.dantz:
same here with mine...

i've sent back to the shop i've bought at 28th January...

and till now i still haven't contact again about my phone...

ps: sorry for bad english i'm indonesian
[HTC One X] jelke92:
my solution

I think i might have a solution,

I didn't have the problem with the screen flickering and visual problems, but was having the problem that sometimes the screen won't turn on out of standby mode. It always took some time to get it working again but it eventually did. Also the 3 lights under the screen where on and I could change the volume.

I tried flashing a new rom and safe mode but it didn't help. The thing that did work was changing the cpu speed with setCPU. I changed it from 51 Mhz - 1500 Mhz to 102 Mhz - 1500 Mhz and it is still working for me.

So try that.

same problem

Hi guys, Im having the same problem with an unlocked and rooted htc one xl, any other advise on how did you solve the problem?? Thanks!

Reball the chip
[HTC One X] Walderstorn:
Have u tried with a copper coin or something, bigger area and shouldnt be to thick?!
[HTC One X] plagued:
fixed

OK update on my earlier post, I'd been putting up with having to warm my phone up and give it a good squeeze just to turn it on, but it had been getting gradually worse. I couldn't tell who was calling as you had to squeeze it before the screen came on and it comes on automatically when someone rings, and it eventually got to the point where unless I was applying pressure I couldn't keep the screen on.

I decided to have a go at fixing it myself, I was fairly sure the issue was the tegra chip that sits on the back of the main-board sandwiched between the back of the screen and the main-board, so I took the main-board out, removed the shielding and then decided to try a basic heating to reseat the chip a little. I shielded off the rest of the board to protect the other components as best I could and then heated up the chipset with the heat gun end of a gas soldering iron, whilst monitoring the rough temperature.

to apply a bit of pressure I took a small square of aluminium from some 0.7mm plate and used arcticsilver to pop it on top of the tegra chip

The shielding just about still fits on although it's snug, and it all screwed back together fine.

The end result is I'm only three days in now but it's been working perfectly, completely fixed. I'm not expecting it to be a permanent fix but if it goes again I might look at the cost of getting the chip reballed, as that was definitely my issue.

*man this took about 10 minutes to type as apparently my "post was flagged by our system and was blocked from submitting" no idea what it didn't like, especially as It seemed fine with the warming squeezing and turning on ;)

HOX LCD MESS FIGURED OUT... hopefully

well I really never contribute by posting something that could help but this time I feel so frustrated that would like other not to feel such way so Im posting apparently according to some complete assemblies and lcd's for the HOX there are 3 versions of lcd's which are not totally compatible with all HOX especially if they are from at&t or the international version or even the roger's version in canada well theres all the explanation in this link eventhough im still a little confused cuz supposedly i have the yellow flex one which is for the at&t version (dual core or xl) but somehow you need to plug in the original one and then unplug it and plug in the new one but i mean what when the battery goes dry i mean that's what just happened to me and i dont have the previous lcd or flex to conect the freaking phone anymore something i noticed is that when i connected the at&t original lcd-digitizer assembly there was a brown thin bar on the upper right corner like loading drivers or something well it seemed that to me also there's a tiny difference in the very output of all flexes well you guys check your own but according to this links theres a yellow flex, a green, and a yellow and green one so i hope this helps a bit a least to figure out what happens to our devices. http://www.ebay.com/itm/HTC-One-X-F...e_Replacement_Parts_Tools&hash=item337e1dbeac
[HTC One X] Insecret:
I just thorw my HOX to the garbidge ... because of the same problem ... so if someone wanna some parts from it like antenas or... don't know aaa good batt

So I have:

A verry good batt (used only 2 months)

Wi-fi antenna

both cameras

the middle with the connectors and the vibration motor

and the back case :P

Everyone is for free just to pay the transport
[HTC One X] plagued:
I wish you'd offered that earlier as I knackered the back case and camera when I hit it with a hammer :rolleyes: and had to buy a new rear camera and glue in a new rear lense.

I'd chuck the case and cameras on ebay, should help cover your losses a bit.
[HTC One X] Walderstorn:

[HTC One X] Jurrvoss:
FIX !(Most prob temporary)

He guys ,

I to experienced the same problem ! It just started one day; screen wouldn't turn on but the hardware buttons would light up , and could hear the volume buttons , so the phone worked perfectly right? I thought it was a software failure , so flashed new boot , recovery, RUU , Rom , kernel , but nothing worked and it got worse very fast .

First I could apply pressure right beneath the camera and the screen would turn on (sometimes graphical failures , very pixely ) but it became geniously worse where it came to the point where I couldn't get it on anymore.

I thought , well let's crack it open and have a look , so I checked all the flatcables , but all were perfectly attached so I searched some forums , where I came to this one and I read it had to do with the tegra chip.

So this is what I did :

-Turn of your phone!

-Crack open the phone , do this very patiently , as it can break very fast;

-Remove the flat cables , and also be aware , you have to be VERY carefull!;

- Remove the screws , I believe there are 5 (one is hidden under a VOID sticker);

-Remove the motherboard from the screen;

Now you have a metal plate which can be removed if you put some pressure beneath it with a screwdriver or some sort

And there it is , the tegra 3 chip.

Now the problem is that the chip doesn't apply enough pressure to the board anymore since it probably was getting too hot and changed position.

You have to have some sort of heat blazer which can heat the chip ( beware of the surrounding motherboard) whereafter you apply a lot of pressure on the chip , and let it cool! It can have a lot of heat , but don't push it too hard. after every session , plug your screen flatcable in and test if it works. IF it still works after 30 min , get everything back in the right order , but before putting it back in the case , test it one more time and see if it works.

I can't promise it works with your device , but it's certainly the fix ! Even if it's temporary , I'm satisfied. Haven't had any problems since than , and that's about 1 week ago.
[HTC One X] iMack007:
Seems to be working for me to

Yeah I had undervolted & underclocked my One X in an attempt to minimise overheating. It worked to large extent, but I'm thinking lowering the min cpu from 102 to 51 mhz might just have deprived the cpu & screen the bare essentials. Can be sure just yet, but so far so good.

Thanks for the heads up
[HTC One X] iMack007:
Update! It's no longer working

It seems it was destined to only be a temporary relief. The symptoms are back in full swing.
[HTC One X] Oadbylad:
When you say you stabilised the chip just what do you mean as have got the same problem ..try a restart with pressure just below the camera and bing the screen comes to life

So it looks like mines the same as yours....was :)
[HTC One X] reslan_912:
yes exactly really disappointing :(
[HTC One X] Zinta:
I have had the similar problem with the screen backlight not showing about 98% of the time, with the pushing on the screen to turn it on for the 2% of the time.. I had sent it in as it's a hardware fault as i flashed numerous roms to see if it was happening and it was. So i returned it to stock and relocked with original recovery, It's currently in repair so would this mean that I shouldn't be charged? Or does that normally come at the end of the service? I only ask as minus the bank holiday monday it's nearly 5 working days since they received the device which they specify is the average waiting period.. Would it be recommend that I contact a HTC representative just in case anything goes wrong? :)
[HTC One X] Oadbylad:
Lets not get "the back light" and the "BSOD" mixed up

If you've a back light problem you can usually see the image on the screen albeit blacked out

BSOD you cant see nowt

reslan_912...i see what you've done now ...ive taked an HOX back off and stripped down the mid frame... you've then removed the dust cover on the motherboard and inserted 2 pieces across the chip as a brace just to give little pressure

I then presume you leave off the dust cover to help with the cooling issue

I cant see as this is a permeant fix but will give it a try
[HTC One X] Zinta:
Yeah i realized that after posting but I listed it in as I did have the backlight issue once but I am sure its the BSOD as I did send it off for repair and got it back on 4th of this month, and now the BSOD is back as well as having the screen glitches/artifacts.. I say glitches they occured a day or two before the BSOD was back. So I sent a ticket for either a better form of repair or replacement..
[HTC One X] Oadbylad:
Good luck with the repair mate

Me... ive no faith in HTC at all

Ive now had 3 and ill have no more...good image and speed dont count for reliability and build quality

Wish i'd never sold me Samsung Galaxy Nexus :(
[HTC One X] Zinta:
Cheers! I've been with htc since my first touchscreen the touch HD, had no problems with any device till this one last month.. A year after purchase, so quite annoyed but if it can be fixed or replaced then I think i'll be happy haha.. I just hope it can and will be repaired properly :/
[HTC One X] chaikowsky:
HOX screen flickering and won't turn ON - probably solved

Hi everyone!

Let me share my experience with this problem.I have a HOX international with this problem and start to make experiment to see from where came this problem and definitely it shows that is hardware related to motherboard and especially to soldering of Tegra3 processor. So I decided to put thermal pad that I get from old DVDRW device, one on processor's plate and one in hole of backplate of screen that is made for same processor! So for now it is 10 days of use and no signs of problem. Hope this can help to someone!

[/url] [/IMG]
[HTC One X] HTC Venom:
is it still working well for you?
[HTC One X] chaikowsky:
Yes! It still working without any glitches! I'm using it for my dayly business work and surprised how fast and stable it is working.

Just worgot to say to take attention on thickness of thermal pads, because if they are too thick, they start to make a pressure on lcd which is resulting in a spot on lcd that is visible on white screen!
[HTC One X] HTC Venom:
thanks for the fast replay

thanks for you answering this fast

since I have noticed that there are too many people here complaining from the same problem again and again and still no one has placed a permenant fix for the error, and I think you should place your way for repairing the error as a sticky thread here at the one x
[HTC One X] jaselibertas:
Hi Chaikowsky,

Can you give some details on how you managed the fix? I'm actually scared of opening the device.

Then again, I'm just out of warranty when it happened. So wth, I'd give it a shot.

It would be a huge and awesome help if you can detail how to open, what type of heat sinker you used on which chips.

Cheers,

Jason.
[HTC One X] chaikowsky:
I don't wont to be a rude so forgive me but :

"I'm actually scared of opening the device" - Then probably you will mess up device, so I warning you - don't try it by self. It is simple, but for people with hardware skills.

If you still insist, then :

1.Disassemble device - google it,there is full of tutorials and videos!

2.When you get access to motherboard, remove gently the metal shield that covers tegra3 processor.

3.Get some thermal pads for example from old useless PC DVR....etc, or buy new. The thickness of bads must be 0.5 - 0.8 mm maximum!!!

4.Depending on size of pads, put one or more or cut the size! Idea is to cover processor's metal plate. Put back the metal shield.

5.Get another pad and put it in the square hole (look at photos) that is on back side of screen's plate.

6.Assemble gently device and pay attention on pressure that makes on screen throughout pads. It is visible when you start to screw mainboard to the screen

Thats all! Cheers!
[HTC One X] las_kjam:
Can you give us an update on your phone fix, is it still working perfectly? or the problem is back?
[HTC One X] chaikowsky:
Yes! It still working!
[HTC One X] HTC Venom:
updates

So since I still have my device under warranty though its rooted , I went to HTC repairing center at my country and I talked directly to HTC local engineer guy , so here the steps that he will do to get the device repaired

1-there a chance thats the problem is a loose cable connection which will be fixed for free

2- and there a bigger chance that there is a loose CPU or chip connection with motherboard that may require total motherboard replacement

3- if there is a need a to change the motherboard they must contact HTC company describing the current situation of mobile phone for being rooted and the the main cause of problem is a Hardware default due to manufacturer problem and because of rooting

4-he will be waiting for response from HTC company and they will call me back on next Saturday (after 3 days from now) and will inform me with the final decision

5- if warranty doesnt cover repairing my motherboard I need to pay 200 Jordanian JD which will coast like 250$

6- the other problem that i have at my device that i bought it from KSA with an international warranty and in Jordan international warranty only covers software problem and any other hardware problem that need also to contact back the HTC company

so ill update this my situation later once I recive an update from them next saturday

updates on 24 June 2013

I have contacted the chief engineer at HTC repair center here at my country , so I have noticed at my device glitches at screen and BSOD

,and after a brief discussion with him he informed me that my device did suffer a hardware fault by poor wielding of Tegra cpu to mother board as its should be HTC's problem not mine , and he still waiting for a response from HTC regarding my device since last week as my device has been previously rooted , though at this moment I'm not hoping much
[HTC One X] 4K_Dohc:
Thanks. I've opened up my HOX and now problem 90% solve. I cant say 100% done because last night till now got 1 time can't power up. Anyway this is the best way to get the problem solve without any cost. :good::good::good:

One question, if I put thermal tape on processor side but not on LCD side is it ok? I felt too thick my HOX can't close fit.
[HTC One X] chaikowsky:
In my humble opinion, powering or switching on the screen is separate problem that is related to DC-DC module that is responsible for generating a electricity for lcd back light but it is another story!

If your thermal pad is too thick, you can replace it with thermal paste. Idea is to transfer heat from processor to metal back plate of the screen and at the same time to protect processor from mechanical vibration when you drop or put somewhere the phone. This idea come to me, when I open my second HOX Plus. There was slight deference in design. They put secondary copper plate at same place to improve heat release!
[HTC One X] 4K_Dohc:
I re-open my HOX and remove the thermal tape on LCD side. Now works great.... 100% turn on:fingers-crossed::fingers-crossed::fingers-crossed:
[HTC One X] chaikowsky:
I'm happy for you and hope that works! This will reconfirm this solution!
[HTC One X] vintulin:
I hopre this will work for me

My HOX also got the same problem. BSOD. Can I just use thermal paste instead of thermal pads on both processor and lcd?
[HTC One X] chaikowsky:
Yes, No, who knows! This is not manufacture recommendation, it is experimental fixing! I already wrote what is idea, just read!
[HTC One X] las_kjam:
I don't follow, you're saying that the screen not coming on is another issue, so what was the issue you posted the fix for in your first post then?
[HTC One X] chaikowsky:
May be you dont read or... Main problem is glitches on screen.Second one is that screen wont turn On.Many people think that is same, but it is two different bugs that usualy came together - i dont know why,probaly it is releated to hardware !
[HTC One X] Marius The Boss:
Mine also started to have issues with the screen not turning on! I think it has something to do with the heat because when i'm charging it doesn't have this problem.,the screen wakes up without problems...

Is that one that you trying to fix?
[HTC One X] 4K_Dohc:
The one that I fixed but the problem come back after few days, but anyway far more acceptable then previous. The other HOX start to have charging issue. Oh man, just 1 year of purchase. Feel like I'm buying LG device...
