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.

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.
I will try to explain again. If I look directly on the LCD screen then I only see a white screen. But if I look at the LCD screen via the touch screen (that is - I put the LCD off the touch screen) then I do see a display and not just a white screen. Between touch screen to the LCD screen was a bit liquid I had not known what it is and cleaned it. The problem is that right now even though I put on the touch screen the LCD and see display, the display is very weak. Why only when I look at the LCD via the touch screen I see display? Why when I look at it (on the LCD) directly I do not see a display only a white screen? Why after I separated the LCD and touch screen and then put them back together the display is weak?

Hi guys
So I bought this TF101 at an auction and got Kisskat 4.4.4 on there. However I have green across the LCD which is very noticeable on the keyboard in the form of lines. In images its like the whole image is a green overlay though. Reminds me of the OLD crt TV's when something goes wrong and you loos a color and everything goes blue or red or green.
Plugging the HDMI cable the display is perfect on my TV. I can also see the green in recovery but with TWRP being blackish its not really that noticible. Also pure white backgrounds like a clean browser screen is fine. Its when colors are introduced that things get messed up. Icons and photos look pretty bad.
When I press on a key on the keyboard it turns the normal shade of grey/black just on that key. When I let go the green is back.
I did check the lcd cable inside and it was semi out on the one end but pushing it back in and even re seating it a few times did not solve the problem. I saw some super scientific methods of slapping and dropping the unit but either I didn't slap mine hard enough or its not working
It like the green pixels are moving -- difficult to explain. Also the screen flashes sometimes at when I switch it on .. like a florescent tube switching on. Do I need a new LCD or is the a motherboard problem? Anyone had this before?
Hi,
my name is Josemari, from Spain.
I have a TF101 with dock (and original rom from Asus) that does not display anything on screen since a soft fall from 10cm (daughter in a very very small chair).
When i plug the charger, it works (and beeps -charge-). When i plug the dock, also beeps. When i connect through hdmi output to my tv, it also works. I can use the tablet perfectly with my fingers.
What can i do?
I disassembled the tablet and i checked all conectors, but i do not see anything wrong.
Thanks.
I had the exact same problem. Even though it has fallen before without a problem, in my last 2 cases it was a loose connection for the video screen. I had to open up the tablet and simply push the video connection back on all the way. It's rather easy if you're familiar with taking things like this apart. Make sure you are careful when you re install the side trim that holds the buttons. It's easy to break the red tabs that press against the buttons. It may be helpful to you to look up a disassembly guide. I believe if you google the specific issue you will find pictures. Again it's been a long time. Hope this helps
I have the same issue since a few days.
Difference here, when I boot up (holding power button until reboot) the screen is on (Asus logo and boot animation)
The display goes balck / disappears (backlight off) when the lock screen comes up.
Checked the inner display cable and connector with no success.
Did a factory reset and it was working again, until I changed the brightness to a higher level. Then the screen was dark again.
I managed to change brightness to a lower level using the working HDMI interface. After that I switched the tablet off and on and the screen was lit up again.
Another effect: when power adapter is plugged in, I can go to a higher brightness level until the backlight turns itself off.
It looks like a hardware defekt of the backlight electronic to me. Couldn't find any spare parts, such as backlight inverter, though.
Can anybody confirm this or knows how to repair?
I will use it at 30-50% brightness now and see if it gets worse over time.
Hey,
I was replacing my screen, when I went to test it instead of the google logo I got a fully green screen, the phone booted, but continued to be green. The always on display looks exactly as it should. Once it was fully on, I managed to put my pin in blind and the phone all works fine (it seems), and some black gets through, I assume the screen turns off those pixels which is why maybe that shows up correctly(ish).
The interesting thing is, I did at one point have to working fully, full colour, this was between reconnecting the ribbon cable and restarting, but I pressed the power button to sleep it and then hit it again and if I remember correctly was green again. So that made me think "poor connection" of come kind. What's even more strange is that when it is green and I press the power button to sleep and wake, the screen appears at least to display the full colours at the end and begging of their animations respectively. Maybe its not full colour, but at least it's more visible.
The final thing is when I go into the bootloader, sometimes it's full colour, and others it's got the solid green effect where black isn't displayed. What's odd is, even when the bootloader is showing correctly as soon as start is click it goes to a full green screen again and we don't see the logo at all. Also I managed to get into safe mode and it made no difference. It's just odd that it seems to decide to green, rather than due to any cable tussle
Basically has to a cable issue, but I'm not sure how to troubleshoot it, and advice on how to proceed would be much appreciated. Like if the screen arrived faulty, if the connector is damaged in the phone so it can't be used, and the motherboard would need replacing.
Thanks,
Dillon
In recovery mode, there's full colour as well, I factory reset the phone, but it made no impact. However entering into recovery mode did flash the google logo and some of the screen whit, and the same thing happened on reboot from recovery mode.
It seems so odd to have these kind of consistent moments of colour and not colour if it's the ribbon
I should have also mentioned, that the clamp is broken, could that be the issue, does the connection need to be screwed in?
Also Here are some images of both the phones connection and the screens
I'd say jb weld your broken clamp before buying parts. Could be as simple as that it's not a tight enough connection
