Help Fast changing pixels - banding - screen defects?

I had an issue with banding, I uninstalled the widget and then reinstalled it again... Problem fixed!

I did the same thing. It's only happened with 3 widgets, power control plus, task panel x, and the calendar. Ihavent seen those lines in a while now.
 
My friend had the issue with the camera the other day. He opened the camera app and had the banding issue. He selected "Power Off", then powered back up and it didn't help. Eventually the banding went away, but he didn't remember if selecting "Restart" fixed the issue.

Hopefully HTC and Sprint will release a fix if it's related to sense, but to me, it's either a video driver issue or a hardware issue. Hopefully it's a software issue since it tends to go away. I've had the issue several times, but I haven't seen it in about 2 weeks.

It's related to Sense (probably because in order to get the 3D carousel effect, they are "skinning" textures of the icons and widgets onto a 3D surface, and there is something going wrong with the texture mapping process.

Because Sense 3.0 annoys me for a variety of reasons, I've since started using Go Launcher Ex, and I have not experiences *any* of these problems even though it was a routine occurrence for me in Sense 3.0.
 
Anyone with a Evo 3D have any bad pixels? I have one bad pixel on mine and it is driving me nuts. The screen is so nice, but any movie I watch or pictures I take or look at it stands out especially if the picture has dark colors around that pixel. Of course it is in the middle of the screen. Every thing else is good, do you think I would be able to exchange it out for 1 bad pixel?

Thanks.
 
I suppose you have to leave the screen on to accomplish this. Too bad there is no option to turn the back light off to save battery.

I have had a dead pixel on my Sprint HTC Hero since the beginning, but it never really bothered me much. I am giving this a whirl to see if it can fix it.
 
Believe that's optional in that app I linked. (??)

I had a JVC tv that I had to do this to for several hours - it picked up black lines at the 4:3 border from all the classic movies I watched on it.

That was older tech, just saying it can vary a lot if this is going to fix it.

Again - best luck.

If you left the pixel stuck for too long - years? - you've deformed the chemicals within the LC layer and it can become unfixable.

Ironically, this app actually showed me ANOTHER dead pixel I have on that screen. I just laughed because I had never noticed it until I tried fixing the first one. :D

Indeed, that pixel has been stuck for well over a year now. Eh, I will see if it helps. I set the sleep mode to on and the screen did turn off, but I was wondering if that means the screen is, indeed, off or just the back light. I would think that the screen would have be on to affect any sort of fix on the stuck pixel. :)
 
If it's working sensibly at all, it's just auto-set the brightness all the way down.

The LCD is just an array of colored apertures - this makes it simply permissive of the backlight as you know.

The passing of light (backlight) ought not matter here - so long as the control circuitry is being pulsed, that's all that really matters.

Exactly. The back light should not even need to be on, so long as the screen circuitry is getting pulsed.

Well, I will let it go for a couple hours and see if it accomplishes anything. If not, no harm done.
 
Ha. Well, I just decided to do a quick check on my brand new Sprint HTC EVO 3D and lo and behold it has one stuck green pixel on the far left side of the screen. It does not bother me enough to trade it in for one that could be refurbished with even more stuck pixels. I will attempt to fix the stuck pixel on this one too.

EDIT: I am beginning to think that HTC just packages stuck pixels with their handsets. Haha. Just kidding. My wife's new Sprint HTC EVO 4G has one too, at the bottom of the screen. Oh well, they are in places that are not noticeable. No worries.

Is anyone having problems with fast changing pixels? If you look in the upper left corner of the phone on the taskbar do you notice rows of pixels changing from red to green to normal? It happens especialy when I am in facebook. It seems when I open any programs it shows up but if I let it sit there a bit the pixels eventually fix themselves and it goes back to normal. Does anyone else have this prob?

Yesterday while using email and not much else, I got some fast changing pixels on the top of the screen, the screen faded to dark as if the unit was going to sleep even though I was using it, hit the wake up button and the screen would come back up all "snow" every pixel lit in arbitrary colors, the only control that reponds is the sleep butting - can't power off, but it will blank the screen. Pull battery, rebooted, seemed normal for a minute or two, then the same thing happened - after hitting the wake up button a few times the home screen did come up but then shortly went blank and then to snow. Gotta think its the GPU


Running to the store today - I have 5 days left of the 30 day.

Here's what it looks like:

In case anyone wants an update, took it to a "repair center" store that was a frachise - they really ought to denote that on the store locator - and the confirmed the phone was dead, but wouldn't replace it because I bought it at Sprint.com. They said I had to do it on the phone, or go to a "company store" which is about 30 minutes away.

Did an exchange over the phone, but they charge you $500 for the new phone, and credit it you when you send the old one back. That's all well and good, but because I autopay with a corp. amex card, if the old phone doesn't get process by the end of my billing cycle I have to pay the amex but they dont refund my amex, they just give me a $500 credit on my phone bill. Also, the phone rep was a bit shocked that the "repair center" franchise or not wouldn't do the exchange.
