Problem with lcd screen replacement

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.

[Q] Odd horizontal dotted line on my Xoom

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.

I presume you have tried obvious things like rebooting or trying to get into recovery mode?
Otherwise it may be a blown LCD panel, a blown backlight, a faulty or loose cable or a mainboard fault.
If you look really closely at the screen in varying light conditions you might be able to see the display if it's only the backlight, but that would still need the panel replacing.
There is a teardown video on YouTube if you need to take the phone apart.

[Q] Screen Died - Can I resurrect?

So my phone screen will no longer display anything. No boot screen, no nothing. The software is running back there just fine, but I can't see it. Could this be a software problem (display driver got corrupted or something)? If so, would someone be willing to tell me the best way to reset? Is it more likely hardware failure since I see nothing during the boot?
My set-up is as follows:
Recovery: CWM v14.4.6
ROM: EMBRYO 6.10
Rooted, debugging on, titanium backup installed
Any help would be much appreciated.

I think I may have found my answer. The screen has been working intermittently today and sometimes appears tinted red, green or blue. Looks like it's time for a new piece of hardware :-/

For anyone else having a similar issue: screen stops working completely, works intermittently, displays with red, green or blue tint, or displays an inverted screen, my problem seems to be a loose connection with a simple fix.
I followed these instructions: http://forum.xda-developers.com/showthread.php?t=1540425 through prying off the back shroud (the one held on by 7 screws). I believe the screen connector is the one on the left in the picture, just below the power button (visible in the picture between steps 4 and 5). I disconnected this (gently pry up), blew off the contacts to try to remove any dust and pressed it back on. I then put a small rectangle of masking tape in the corresponding location on the plastic shroud (mine already had a rectangle of black tape in this position) in hopes that this would help keep the connector securely pressed against its mate on the board. Finally, I snapped and screwed it all back, and so far so good.
My guess is that this problem/fix probably applies to more than the galaxy s II skyrocket - possibly it will be useful to someone someday...or maybe not.

[Q] Graphical glitching and static

My friend smashed the screen on his nexus 5 and gave it to some shady repair shop. They replaced his screen (with a white one, on a black phone btw, now it has a white dot on top) and he paid a lot of money for it, but now his display won't work, so he gave it to me to fix, as I have some experience with fixing phones and he has no money left. The repair shop refused to take it back and he doesn't want to start a legal battle. As far as I've tested, the phone shows three behaviours. The first is that the phone boots normally, but without displaying anything. I can still hear it getting notifications and can connect it to a computer, it's just not displaying anything. The second behaviour is identical to the first, except instead of a black screen the phone shows colorful static which seems to correspond to screen-on time (when I lock the phone it goes black and vice versa). The third behaviour, which is the weirdest, is that the display works, but everything displayed is glitching. The google logo maybe has the top 20% moved down a bit, the boot animation may be choppy or distorted, the recovery menu may be divided into blocks which are moved around a bit. In this 'mode', I have never gotten it past the boot animation. The reason I wrote 'may' is because it's different every time, but eventually it always just goes black and stops responding until i disconnect and reconnect the battery.
I opened the phone and fiddled with the connectors a bit and found out that pressing the usb board connector to the mainboard seems to cause the phone to switch between these behaviours. I took a small piece of paper, folded it over a few times and put it on top of the connector and then screwed the cover back on to hold the connector firmly in place. That seemed to put the phone into constant behaviour 3 (graphical glitching).
What could be the problem? I know that the static indicates that the usb board or more probably its connector is faulty, but I'm more concerned about the glitching. It seems to me that the graphical processor is malfunctioning, but I have very little knowledge about graphical processing and displaying so I really don't know. Any help would be greatly appreciated.

UPDATE: the phone just did something weird, when I turned it on it displayed static, but then it started drawing the boot animation slowly from top to bottom. And then proceeded with behaviour 3 as usual, the animation ran at about 3fps and just went blank after 10s.

Okay, I have located the exact location of the fault, the USB board ribbon cable that goes over the battery was bent at a sharp angle and then apparently straightened again. If I press it in that point, the screen switches between static and nothing. I have not been able to recreate the glitching since I cleaned all the parts of the phone with isopropyl alcohol. Still, I'm interested in an explanation to avoid further problems with glitching

now it's behaving even more strangely. When I turn it on, it slowly fades from grey to bright white screen and then goes black and starts blinking a red light. What does this mean? Please help

anyone?
