LCD color problem: Weird Teal/Blue-ish

Hey Everyone,
My LCD screen seems to not be displaying colors as well as it should, almost as if it isn't displaying all the colors that it is in fact capable of...
I had some prior problems with my phone, including a non-functional power button, a digitizer with some unresponsive blind spots along the left and right side of the screen, and a very faint/low volume through the in-call speaker.
I had been planning to go inside my phone using the teardown/repair guide, and actually ended up stripping my phone down to the LCD panel.
The good news is I have fixed all the problems that I had set out to fix while doing the teardown.
HOWEVER, my screen is now a weird teal/blue color. For example, when I equip the standard HTC skin (the one with the nice colorful bubble background) Instead of the notification bar/button being a solid steel gray, they seem to have striping pattern with some dull colors of gray but with this teal coloration.
I was wondering if it is more likely something to do with the pcb/lcd getting slightly damaged when I did the teardown, or is it possible it is something to do with a setting on my phone? (the boot screen did load up once, when I was doing the teardown and checking if my phone still worked, I chose reboot as the option)
HELP!

Well more then likely it is the conectors I've seen it to many times when people dicide to take apart phones id say take it all apart and make sure your cabbles are plugged in nice and and firm report back and tell me. Also make sure you havnt nicked anythng on the pcb boards (traces or anything) no nicked cords ect

Same thing happening with mine, it's a week old and I've never taken it apart.

Only thing i can think of that happened that makes sense is a damaged pcb flex cable, thats it.but the weird thing is i fixed everything else. Its annoying cause videos look wack and taking photos is also messed. Ill probably go back into my phone and see what i can do, ive opened it like 8 times so wont be too hard.

me too
Just wonderening if anyone found a solution to this problem as I am experiencing the same thing. I have never taken my phone apart. I have my own post called display color problems. Please help! This is absolutely obnoxious!

I sent mine back to Bell for repair. Took 2 weeks, don't know what they did but it works great now.

Was that an expensive repair? Wish I knew what the problem was so I could try to fix it myself.

Actually it was covered under warranty so cost me nothing.

Well thanks anyway.

Is your phone not under warranty? If it's because you rooted it, you can relock the phone with gfree and restore the BellMobility RUU...

Yeah I guess I could but I really can't go two weeks with no phone. That's the main problem.

Figured I'd give this thread a bump. Really just hoping that someone out there has some experience with this problem. I've searched the net high and low to no avail. I don't want to waste money on unnecessary parts if I just need one. Presently, I plan on replacing my LCD. If anyone has any other suggestions, I'd love to hear them...
Sent from my HTC Vision using XDA App

This happened to me before i first opened up my phone. I wouldn't replace the LCD because i cracked mine, and had to replace it and it still does it. Just try and get a replacement phone from your carrier or the store from which you bought it while they fix it. Easiest option.

amazon, all One X are faulty :(

Hey guys,
today i spoke to amazon germany about the one X, because i had already 3 faulty devices and all devices had the same issue, screen flicker.
The amazon worker said, they tested all devices and every device was faulty, now they are waiting for a statment from HTC. I think its very sad especially for the people who waited for their device, HTC shame on you -.-

Just a bad batch.
Over here in Ireland, very few if any people have had to return faulty devices.

yeah but not in this dimension, i thought a bunch of devices were faulty but not that much, what do you think hardware or software?

The store were I swapped mine 3 times also said there is no "sense" in swapping for a 4th as they are all flawed.

when they cant fix the issue through an ota, then its gonna be expensive for HTC

They may be able to fix it through an OTA. A lot of early ICS ROMs for the Rezound had screen flickering problems, but they've since been worked out. At least there's hope!

If only the level of attention AntennaGate got becomes as widespread for HTCs woes...then we might all get a free case - oh wait that won't fix the Wifi issues, or the flickering...or the yellow spots...

And the transformer prime had the.same.issue, it took 4 ota to fix it. I think I have seen people say it is possibly tegra related

While the problem is very real, I highly doubt that Amazon ripped open lots of boxes and started testing the phones. There are seals on the tape on the side of the box and they wouldn't have been able to resell the device after opening it I think they probably re-tested the faulty ones returned and judged by the number of returns that there was a general fault. By the way, it is easy to determine if your phone is a new never used one or not. When you switch the phone on, if it takes ages to start, going black for a while, it is new. If someone had switched it on, even if they didn't do anything, and switched it back off again, it would not take long to turn on the next time, due to fast boot. Since the fast boot setting is always on after a factory reset, I believe it is impossible to get the phone back into a state of "reset + long boot".
Also, having now been on my 6th phone, every single one of them had flicker. They were not all built at the same time or bought from the same store. I found a test case that could make any of them flicker
1) Battery below 50%
2) Brightness set to 40%-50% (varies a bit from phone to phone)
3) Go to the XDA forum web page on the phone. As the page is loading up, focus on the background and will see flickering as the CPU activity increases during rendering
I think there are two types of flicker. One that happens all the time on some phones most visible on grey backgrounds. And another type of flicker that happens at certain brightness/battery/cpu levels.
Another test case is:-
1) Set brightness very low, such as 20%
2) Go to app/play store
3) Choose "My Apps"
4) This may only work with a considerable number of apps..I tried it with 60. Rotate to landscape, watch very carefully the grey background...and then when the white re-appears, watch the brightness change upwards after it settles.
5) Rotate to portrait and watch again at the grey, then the white brightness levels
A friend bought a HOX just recently and it shows as well on these 2 test cases.

I bought my HOX from an italian ebay seller (a month ago: htc23) and device has arrived with an Amazon Spain package.
Never had any issue: no screen flicker, no flex ..no gap

When you have to set it up just to see it flicker that shows it's NOT an issue in my eyes - 'battery less than 50%, turn brightness to this level, etc.'
I have my phone on auto brightness, let the battery run to nothing sometimes and I have NEVER had the screen flicker. I'm saying there might not be a problem but when you get it under very precise circumstances I think you're deliberately looking for a problem...

I didn't go looking for the problem. I stumbled across it. I am very analytical, so once I find a problem, I determine the test case that produces it. I didn't return any of my phones for this problem. They all had other issues, such as screens that were not seating properly, one that displayed the left part of the image on the right side and vice versa (really weird that one), one that had a massive blue splodge near the middle of the screen etc etc

That I can accept but this whole flickering issue seems a bit far fetched. I've got VERY good eyesight but cannot see anything wrong with my phone so I either have a perfect one or I'm just not bothered by it

Not that much? How many does Amazon DE have in stock? 20? If it's more than that I highly doubt they opened every single unit to determine they're "faulty." The flickering's s/w and any phone is subject to it. Not all do, but all could. Last announcement on May 2 was HTC identified the issue and was working on an update specifically to address it. You're better off waiting until that fix is released.

you are so lucky! mine is an ht23 too, but it does have flickering and suffers when pressing the LCD left side. HTC says it's normal for an LCD which is pressed, i've tried to explain them that this happens only on screen borders, that most devices have no flex issues and so on.....they don't want to replace it.
really disappointed.
my first and last htc for sure.

Indeed, but also how often are you staring closely at the screen while a web page is loading. It hasn't really bothered me but if it was flickering the whole time on a grey background, that would certainly annoy me.

Don't think I've ever seen a panel phone, tv or monitor that doesn't flicker under certain circumstances if you really look for it. Unless of course it's happening all the time in which case something is wrong.
My One X? No problems here as far as I can tell and I'm not about to start to try and make them happen either.
Don't forget also - everyone's eyesight is different. Anyone familiar with rainbow effect on DLP projectors? Doesn't affect everyone - it's something to do with the way the brain interprets the signals.......

Strange, as my last 2 had that issue. Made a youtube about it, send the link to HTC support and they contacted me. They told me that it was not the way an One X panel should react on pressure. Got a refund after the 3rd one, now I'm struggling what to do with my premium navigation license.

If its far fetched why have HTC admitted to the problem in one of the many threads raised by users facing this issue?

Will it get worse? Screen Flex Issue

I got my One X over a month ago and all was good. My nephew dropped the phone last week and the phone screen got scratched quite a bit and the phone started playing up. WiFi kept dropping, software freezing. So since I still had insurance with my network I ordered a replacement. I received the replacement yesterday and when I pressed down the the sides of the phone I could see ripples all the way to the top of the screen. I called up and got a replacement for the replacement and it arrived today. Phone was completely drained in battery :S but I let it charge and then tested out the screen. Flex is still there but slightly less. This one is much more usable the the other but I was wondering, will it get worse? Do not remember this problem on my old one. Is it worth getting another replacement or should I stick with it?
Thank you
(1st was HT24, 2nd was SH24, 3rd is HT24)
And now I found a bright white pixel on the screen :crying: I'm seriously considering asking for another, but I'm dreading how bad that one will be.

I do also have a flex on my HOX. I own it already for 3 month. But it doesn't get worse. I think you should not worry about it.

I have no screen flex unroll I push really hard on ny screen and even then its only where I've pressed doesn't spread across the screen.
I would ask for a replacement but that's just me I take things back for the smallest of issues

See the thing is that the new one I received today shows the flex when I push on the side of the screen but but doesn't spread as much as the 2nd one. Seems to be fine with normal use. I'm just hoping it doesn't get worse as the screen is used more. I have 14 days to get this replacement replaced again so I will let you know how I get on.
Any more views would help!
Thank you

You have 14 days so wait for like 10 then get one anyway might get a perfect one

It doesn't affect it. You won't notice it with day to day use either as you won't be pushing that hard.

Yellow on my screen?

I recently got a replacement phone from VM and I noticed that a yellowish tone would sometimes appear on the top left of my screen... Is it permanent, does it go away, is there a way to fix it?

it's a faulty LCD
Sent from my ST25i

Happened to me to.. either over time it went away or my eyes are used to it and cant see it anymore
Sent from my One V using xda app-developers app

I'm not sure what makes it appear, but sometimes it's completely invisible, and other times it would flare up for a bit. Maybe it's the temperature under load cause I mostly see when browsing the web, or watching vids on YouTube. I guess I can call VM and get another replacement, but if these are early builds then there's a good chance that they will have the same issue since it was common thing back in April and May...

Its because of the heat while on charger I think mine went away after a week or so
Sent from my One V using xda app-developers app

Its not a heat problem or anything. It is just the glue used to stick the glass togethet. As you said this issue was a common issue in first one v's that we're bought but after may loot this issue is gone. I will consider getting a replacement.

As icebox said, get replacement and make sure the manufacturing date is not before june2012. I got mine replaced as the yellow did not go away even after 3 months!

Htc one x lcd display problem

Hi everyone,
I am using htc one x for over two months now, and recently i have noticed that my lcd is not working correctly.
I am using arhd 31.1 now, and before that i have been using arhd 31.0, and so on and so on...
This error happened when i installed arhd 31.0, but i tought that it was the rom problem so updated my phone to arhd 31.1. And problem still persists.
The problem is following, part of my lcd display does not recognize gestures, or touches or any other input, it is like that part of lcd or digitizer is dead, i cant do nothing in that area.
Picture explaining problem more precisely and effectivly is in attachment, those lines you see should be continous.
So what do you guys think this is? I am really pissed and you cannnot imagine how much this is annoying :/
Is this hardware problem or something else? Just so you know my phone never dropped, and it was never punched or anything.
Any help or somekind of advice would be great.
And I dont have a warranty.
Regards.

I had the same issue with mine. It was deemed a hardware problem and the retailer gave me a credit to purchase a new phone. Mine was still under warranty.
Sent from my HTC One using xda app-developers app

Had a similar problem but with the lower part of the digitizer, had to replace the whole screen+digitizer assembly(pity you cant replace only the digitizer).
I have one question tho - was your phone in moist environment -e.g pocket while running etc?

I cannot say it was in moist environment, but i use endomondo a lot while running, but then phone is in armband never in pocket.

I have this problem too,but in lower part of screen.I turned on visible touches in developer options and it just skip this area.And my auto touches in this area sometimes.
I have solution that worked for me but problem is coming back sometimes,so i must do that all over again.I hope it will help to someone still using this phone.
I solvet the problem by pressing up right edge of of my phone.When i press it it looks like its coming back to place.Try pressing phone with two fingers on edges of the phone and see if it makes the difference.And if it not work use lighter igniter,just google unresponsive part of touch screen fix with quartz lighter
I hope i helped and if you have any questions ask me.
And sorry for my BAD english!
