Hey,
I got problem: after changing broken display, new on has some issues: i can see very small blinking horizontal stripes (darker and brighter, so they are visible mostly on colors other than black/white) and they are moving, like when you record screen with different refresh rate.
Also sometimes there is problem: when I turn on screen, after few seconds all colors change to bright and contrast is extremally high (like with using some bad picture filter), or very rarely i have vertical stripes, which become more visible, all screen becomes brighter and there is no response when I touch screen. This two problems dissapear, when I turn off and on screen again. (but I still can see delicate horizontal stripes - these are all the time)
Is it problem with software, or hardware?
If hardware, it is because broken/poor quality screen, or there is some issue (damage? dirt?) on the connection between screen and mainboard, on socket or band?

I have recently replaced a broken screen of an apache with a new one and when i turn it on the screen turns on and is white, when I look at it side on I can see the devices screen is working but it is faded, e.g the today screen is there but very faded.
I was wondering what could be the problem?
I replaced my screen recently as well and had a similar issue. Make sure the ribbon cable coming off the screen is attached correctly - you'll need to raise the black bar on the connector, push the cable all the way in, and lower the bar to make full contact.
hi friends
yesterday night unfortunately my son fell over my touch pros touch screen when i checked at night the phone was working perfectly and today morning the screen is showing 1 big rectangle mark with small dots on the screens surface and the screen is not responding phone is working but screen not responding
will i have to change the screen ?
please help
The same thing just happened to me!??! Exactly!? If anyone has any tip, please let us know. It's a rectangle slightly smaller than the screen and it's a blurry colorful appearance with a grid of faint dots. It appears as though layers in the touch screen have separated. I didn't do anything to my phone to prompt this - no abuse whatsoever.
New WM 6.5 ROM on starting uses only blue and yellow in v low resolution.
Display technically OK - shows 3 colours on bootloader, and on Hardware Info it says 64k colours - just legible in its 2 lo-res colours.
After some duration 5-15min, using screen off/on h/w button, display suddenly clears to full colour and display resolution.
Free storage 169.15MB, free program 67.12MB, no change with cleanRAM.

Ideas? -and thanks in advance
This is most probably faulty lcd screen, so you might have to replace it with a new one.
Thank you, yes, tho it's odd that this onset only after flashing (and there was no mechanical damage).
Have clarified that switching screen off at any stage in the start-up will resolve it (gives normal screen) so I'll not try buying a new screen just yet.
May it be relevant that the first flash was interrupted by my PC's BSOD (first in months!); perhaps a voltage spike damaging a memory address?
Have you tried flashing it with the same rom, or the origional, to check if it is a faulty system file?
No, I'm nervous about flashing it again in case there was some hardware damage to video locations of memory during the BSOD - is that possible?
Have more detail on the fault sequence after soft-reset:
1. "smart mobility" logo displays normally (white text , black background) for 3s
2. red pixels disappear from this logo when Device ID data displays in red at lower R corner.
3. HTC splash screen displays in v low res in blue & yellow without red
4. start-up proceeds to desktop, display no change - unless
5. power off-on anytime after splash screen seems to re-start the display in full res and normal colours.
Sorry for delayed reply due to holiday....
fixed
fixed by flashing an early HTC ROM
perhaps others can understand why?
Hi,
After powering on my Xoom today, I saw there is a horizontal dotted black line across the screen (Vertical if i put the screen on portrait mode)
Going into Fastboot mode, the dotted line becomes white color. Anyone experience this before and any solution to fix it?

I can't seem to pull up the photo, but it sounds like a hardware issue from the way you're describing it. Your only choice is to send it to MOTO for repair. Since there's no way to prove it wan't from abuse you'll likely have to pay for the repair. :-(
From the picture it seems to be hardware related.
Use the following two tools to see if its not a "stuck pixel" problem.
Display Checker
Display Checker will help you identify dead pixels
Pixel Fixer
If an LCD display is subjected to physical shock, this could cause one or more TAB connections to fail inside the display. This failure is often caused by horizontally flexing the chassis (e.g., while wall mounting or transporting a display face up/down) or simple failure of the adhesive holding the TAB against the glass. TAB faults require replacement of the LCD display module itself. If these connections were to fail, the effect would be that an entire row or column of pixels would fail to activate. This causes a horizontal or vertical black line to appear on the display while the rest of the display would appear normal. The horizontal failure runs from edge to edge; the vertical failure runs from top to bottom.

That looks like your problem.
Hi guys,
Yesterday I noted that the U11 screen is more sensitive than HTC 10 with the pressure and distortion.
If I'm in a dark background and I touch the screen and then move my finger quickly from up to down I can see some screen distortion for few seconds. Please note that I'm pressing it with little force, nothing hard. I tried to reproduce this in HTC 10, iPhone 7 and no problem.
Can you test this? Please put your finger on screen and without taking it off move your finger from up to down quickly against a dark background, picture, or application. Do it along the entire screen. I can see some distortion. It's like the glass is not separated enough from LCD screen. You need to do this a few times as sometimes you can't see it alright.
Sorry doesn't happen here
