Rainbow Effect on Screen

After being in my pocket for some time, there is a rainbow effect on the screen. I can change the location of this effect if I push elsewhere on the screen; however, it seems to concentrate itself right in the center. It has no ill-effect on the touch screen but it is visible under certain angles when the screen is on. I am using the screen protector that came with it. After some time being out of my pocket it dissipates and looks normal.
Anyone else experience anything like this?

Yeah, I have.. I haven't noticed it's touch sensitive, but I've seen the problem while rebooting and also randomly while using the phone.. And it seems like for me the screen gets progressively worse and starts losing all contrast and fades to white. A reboot always fixes it.
My guess is something in the video drivers flips out. But the first time I saw it I thought I had a hardware problem because I found it that way in the morning out of the blue, but I guess it had started doing it 'itself' overnight or something.

I dont think it has anything to do with the screen itself. But the digitizer and the multiple layers on top of the screen that the digitizer is composed of.

Newton's rings isn't it?

Yes that is exactly it - the diffraction of light between 2 surfaces, is it normal; however?
Thanks!

Nooo, then maybe what I'm talking about is different. I'm talking crazy screen, weird 'rippling' going on, screen slowly turns more and more white. I know what newtons rings are.. It's sorta visible in sunlight.
So perhaps I'm describing a different issue. Mine is definitely something with the phone, not the layers.

Screen issue-"Burnt in" image on gray backround

Hello people,
I rarely see a burnt in (like old crt screens) image on the bottom of the screen.
For example when I change the volume, the softkey labels of the today screen are still visible, along with a white line. Most times it is normal so I don't worry very much but I'm wondering if someone else has the same issue.
I've tried many versions of hardspl (because they seem to be connected with some screen issues) but the problem still exists.

Hi i have the exact same issue, i put a post up a month ago not had any response on it. I have a MDA compact IV, not updated any ROM or HARDSPL yet. I was tempted to update to see if the problem could be rectified.
Have you update to a cooked rom? I might send mine back to have it fixed if its a screen issue.
Mine only holds the "burnt in image" along the right of the screen from top right corner to bottom right corner around 3cm in.
Also i have noticed the "Burnt in image" seems to get stronger when the device heats up. If i use GPS or 3G, this seems to affect the screen.
My background is black which makes it really noticable, i think if i stick with the orginal t-mobile white background it's probably not that noticable.

mmm
Perhaps the units you bought where like demo units. Those units that are displayed all day long turned for people to look at them. I have read in another forum that perhaps that distortion is caused by extreme temperatures, cold or heat.

well i'm still trying to figure out what is causing it, as I notice it only once in maybe a week. Maybe temperature is the most probable cause. For me I notice the defect only in gray background (e.g. when changing volume or launching opera).
My unit was from the first batch from expansys (origin htc asia)

It's possible your handsets have screens which are somehow susceptible to heat damage from inside the phone. This would be no fault of your own, but a manufacturing defect.
I'd suggest returning the phone to the retailer, HTC or the operator depending on your situation.
However, if you're using the phone in extreme conditions, ie low temperatures, you may very well find the LCD slow to refresh or have some level of image retention.
Let us know the outcome

i also have a ripple effect when pressing, but its more apparent with black. its also a first gen model, so i think ima make a phone call to htc. maybe a can get a new device.

for the burn in, try this:
1. Go to power settings, deselect automatic backlight management.
2. Pull up backlight level to maximum.
3. Reselect automatic.
You should be ok!
If not, faulty device!

Ok I will try this although I can't see how the backlight can affect the screen. In order to repair it with warranty I would have to send it to expansys uk (because it is not a European device) and I bet it would take long

Have you tried removing the battery for a while - some lcd screens can get the memory effect, and cutting power for long enough normally cures it.

My phone actually holds the previous menu under the current menu.
Example i'm on the home screen, goto messages and send a text using the qwerty keyboard. Back to the home screen, i can see a very faint image of the qwerty keyboard under the Programs hotkey.
When the PIN lock comes on the bottom right is "MENU", i can see a faint "programs" letters icon underneath it.
I will try and leave the battery out for a few hours, if not a call to t-mobile!

ok, i have the same "problem". even after a soft-reset the words CommManager
and Programs are still slightly visible in the boot screen.
but: as mentioned above, turning the device off for a couple of minutes cures
this, and the screen is dark as hell again!
really seems to be some kind of memory effect!
regards,
markus

Left the battery out for a few hours, made no difference. I guess is not a software problem.
will be giving t-mobile a call tomorrow!

:-(
I guess every htc device must have a flaw...
when it does it again I will try to take a photo of it and post it here

Hi same problem here.... See my post below..
http://forum.xda-developers.com/showthread.php?t=417629
I thought it was due to Spb Shell but no, now i'm happy i'm not alone..
But what solution for this??
I'm not worried about the burn in looks.. My worry is whether this behavior of the screen will progressively damge the screen???
I have been using the Diamond at full backlight.. Last few days i've put it down to minimum, but the problem persists!!!

ok, I think it happens when it overheats.
So that is why it is caused when charging.
wtf?

No its not due to overheating, coz LCD screen are supposed to tolerate temperatures upto 80degree C... Dont know if its related to electro magnetic radiation, may be looks like it's more after i use the network...

Hi another mate has this problem Andrew...

Hi,
i sent my phone back to T-Mobile hoping they will fix this issue with the screen. Just received the phone and it looks like they have done nothing On the job sheet all it says is "Software updated"? The problem is still there!
I dont think there is a fix as such, it looks like this is the cause
http://www.practical-home-theater-guide.com/image-sticking.html
I'll try if i can get a completely white background and leave the screen on for a while at the brighest setting, if this will erase the screen issue?

the problem appears more often now on my device....
It does not have to do with heat afterall.
Why would the image "stick" when the phone is off? I mean that many times I see the symptoms right after I switch the phone on.
Do we have any screen experts in the forum?

After calling up T-Mobile and made a complaint saying nothing had been done by the repair centre, they gave up and agreed to give me a handset replacement. Received the handset today, looks like a refurbed one? Anyway my problem is now fixed. Left the phone on a while and it got pretty hot, no ghosting on the screen
The restore was a pain, Wifi didn;t work, the HSDPA didn;t work. But after a few hours messing around it's all up and running so far.

WSOD! Help!!

My tilt is acting very nasty lately. Over the past few weeks, I noticed that when I turned on the display, occasionally I would get something that looked like the static that you see on TV, but with colors. I would just turn off the screen, and turn it back on to clear it.
Now it's gotten worst! 98% of the time, it intermitantly gives me a blank solid white screen when I turn it on. Occasionally I can just turn to screen off, and on to reset it.
I'm running OEM WM6.1, and I've tried to reinstall the OS, but it didn't help. My phone has taken a beating, and the top corner has had a small crack in it over the past 2 months, but it didn't effect the touch screen, or picture. I also took off the cover to make sure the cables were all snug, and it didn't help.
Any suggestions?

Something got corrupted. If you search WIKI, it's call the 3 color screen stuck .. and you're better off posting at thread below. I hope someone can give you help (if you follow those steps and still no good)
As rule of thumb, do a lot of reading first
http://forum.xda-developers.com/showthread.php?t=423486
On a second thought, it might be the LCD itself broken ..

Oh, believe me.. I'm not one to turn to the forums without doing research myself! All the research I was coming up with seemed to point to a slightly different WSOD though. I think you are right about the screen being broken. I've reinstalled the software, and it acts up even when booting up!
Unfortunately, I'm not impressed with ANYTHING on the market to date! If I'm unable to fix this, I'll just go back to a RAZR until the next gen WM7 phones come out. (With a tilt screen of course!!)

Oh, and even though the screen goes white, it's not stuck, as it fully boots up; I can hear sounds, and even activate the touch screen.
Also, I forgot to mention.. the first problem I started experiencing was that my tilt would go back from landscape mode! It was like the video board was crapping out. I could even see a slight flicker in the display from the refresh rate.

hi i think you may need a new Need a new flex cable ribbon as i had the same problem once

Thanks Tayzaa, I think you could be on to something. I'll open it up and take another look!

Hi!
is this problem solved?
WSOD is bug of Hermes. I would know if kaiser have the same WSOD-bug with D-pad?

Screen Alignment

Hey guys. By now, I'm sure most of you are probably familiar with the screen alignment issue (where, sometimes when you go to click on something, it clicks something above or below and is about 1/3 of an inch off).
Well, I've noticed something on my device and was wondering if anybody else has had the same experience. If I have the screen brightness all the way down, I can use the screen for quite some time before this happens. Then, I just hit the power button, put it to sleep, and then wake it back up and the problems corrected. What's weird is, if I have the brightness all the way up (like when I'm outside on a sunny day), it takes far less time for the misalignment issue to show it's ugly face.
Basically, what this says to me is that it might be related to a heat issue from the screen itself. Just wondering what everybody else has noticed.

Yes I have notice it too with the same setting but didn't think much of it and just put it to sleep and woke it up and worked after that.

dont know if its a heat issue, my phone is always on 0% brightness and it still randomly happens.

Screen changing brightness when not on Auto and no power saving...

I just got my Asus tf701t and, while first using it, the home and back buttons did not work in portrait mode and the screen would change brightness at varying time intervals (usually a few seconds) when the brightness was set very low. an update to 4.3 cured the back and home button issue but the screen still can't stay at one brightness level when I set it to very dim. It's not changing dramatically, more like a few percent, but enough to be distracting.
The odd part is that the dimming/brightening issue almost seems application dependent. It occurs far more often in the home screen or skout but almost never when playing shadowgun dead zone or when using naked browser.
Does anyone else have similar issues?
The only posts about flickering on other people's tf701t seem to be related to power saving and I need to know if this needs to be exchanged or if this is a common problem.

I don't have the flickering when not on auto and lowest setting.
However some apps can dimm the screen while loading.
On the TF700 the stock browser did that when loading a page but on the TF701 the brightness doesn't do that.

You have an ambient light sensor built into the device. It adjusts the brightness based on the lighting in your environment. It can't be turned off either.

It can't be turned off? So when you turn on automatic brightness it just changes the brightness more drastically? This doesn't sound right.
Based on the other poster's response, I think I need to return this unit. The screen dimming/brightening happens to often and randomly to be part of my apps and I even noticed, in some apps, that just touching the screen causes a brightness change.
Even if this is by design, it is far too distracting.

My 701 is doing this as well. Turned off auto brightness, turned off power saver, rebooted. When it comes back up the device acts like auto brightness is on, with screen brightness fluctuaating randomly. Turning power saver on and off again seems to solve it, but that behavior is very annoying - it's why I turn auto brightness off in the first place.
US SKU running 4.3 installed via ota, no root or unlock or anything - straight stock. Its also my second device, my original had a bad cable and wouldn't charge. Serial number ends in 072259.

I also tried turning power saver mode on and off and for me it seemed to improve the situation but not eliminate it. I am going to return the tablet and wait for the nexus 10.

Ugh, mine has been doing this, too. Can't believe there isn't a setting somewhere...

Mine is doing the same thing... glad that it's not just me, but this flickering is very annoying

Driving me nuts
I'm having the same problem and it's driving me nuts!
I'm quite convinced it's a software "feature" but currently there seems to be no way to turn it off?
It's one of those "Adjust brightness of the screen based on content" or "Changing LCD refresh rate and colors for power saving" but sadly it does it the wrong way around (This has been going on for a while now, manufacturers don't really get it). When there is a lot of bright content the brightness will rise and when there is mostly a dark screen it will fall.
Of course, this should happen exactly the other way around. When there is a lot of bright/white on my screen it should lower and when there is mostly black it should become brighter thus giving you more contrast but keeping the overall lux that comes off your screen the same...... My Intel graphics notebook does this too and it's very irritating. There they do it by manipulating the LCD screen and lowering the refresh rate and other tricks to save battery. First thing I turned off.
However way it goes though, you should be able to turn it off!

I'm having the same issue. I think it's the smart dimmer option Asus have used before but they forgot to include it in the Asus customised options. I'll have a dig through the ROM to see where it is stored.

I'm having this problem as well.
I have my brightness set to about 80%, Auto-Brightness Off, Power Save Off.
It is very annoying when reading magazines that have a lot of white background. My screen will be stable for minutes then, often on a touch, will change the screen brightness, seemingly by 5-20%.
I was just getting ready to return it, and thought I would check here to see of anyone else has this problem. Has any actually called Asus with this complaint? I would be interested to know if they see this as a hardware defect, software bug, or working as designed.
PS - I just placed a technical support request about this on the Asus Website. Here is my problem description:
Even with automatic brightness & power saving turned off, the brightness of the screen will change over time, often seemingly in response to a touch. (Reading Mode is Off as well.)
The period between changes can vary from several minutes to 30 seconds. It happens both while docked and undocked. It happens with apps and just at the launcher.
The amount of brightness change is 5-20% and it will often seem to step through some values before it stops at a particular one.
Given how fantastic looking the screen is, this unwanted fluctuation is particularly annoying.
I also own a TF201 and have not experienced this problem on that product.

I suspect this is the same "smart dimming" feature that the 700 had.

Yep me too and as soon as I root I'm going to see if the same fix will turn it off

There seems to be no way to disable this. Some believe it's the light sensor, but I've taped over mine with black electrical tape and tested and I don't see any difference in the behavior. Check our my Youtube video if you are a user who doesn't see the issue (look for threads in this same XDA forum).
I've finally been able to get someone at Asus to look into this and it's been sent to TW for review. I haven't heard anything back yet. I strongly recommend that other people who are annoyed by this (I find it tremendously distracting) to search on "asus escalation" which will bring up a special mailbox. Here is the link (although I do not know if the link will work for you). This should get looked at by someone with at least some ability beyond reading a script. If enough people do this, I think that they will fix it. Since you can temporarily override it by toggling smart saver on/off, it has to be fixable by software.
