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.

I am having an issue with my TF where I cannot set the Brightness scale to anything but "Auto" - if I attempt to manually change it, the backlight turns off and the only way I can get it back on is to plug the tablet into the charger. The unit then jumps up to 100% brightness, but if I unplug it, the backlight turns off.
When the unit is plugged in, I can move the brightness scale and can see the screen dim and brighten as it should...
I have the latest firmware (8.2.3.9)... any ideas???
Some more info... if the backlight turns off, I can do a reset of the device by holding down the power key and then turning the unit back on. The startup screens do display properly, but when the device comes up, the screen darkens again. You can also make out the time and see some transitions between screens very faintly... its just the backlight that is off, everything else works fine.
The screen illuminates properly once again when plugged in...
The fact that the startup screens (the Asus and eee pad title screens) illuminate properly leads me to believe that this is a software issue. Help!!
Addendum: It appears I CAN adjust the brightness scale without being plugged in somewhat... the backlight turns off if I attempt to slide the brightness scale above 2/3 full brightness or so... anything lower than that is fine (or 'AUTO'). But, again, if the device is plugged in, FULL Brightness is possible.
This is very frustrating... I don't know whether to RMA this (who knows how long this will take), return to BestBuy (who doesn't have any units), or wait for a possible software fix??

ive seen one othet person reporting this problem,
since its not a common problem,
your best bet is to RMA it.
dig in in the forum snd see what the other person did.
what did you do to get this issue sorted? I have the exact same problem whilst running a rooted Transformer running Prime 1.5
Same problem here
I just started having the same issue, too (stock ROM). Tried factory reset, but didn't help.
Has anyone else found a solution, or should I just RMA?
same problem here
Is my device bricked?
Had device inserted into keyboard and plugged in all night. Batteries should all be full.
Light on keyboard is green.
Cap Lock light comes on when pushed.
Computer makes camera shutter sound when "camera" button is pushed.
Nothing happens when holding power button down for 5, 10, 30, 60 seconds.
Same when holding power button down with volume up for 5, 10, 30, 60 seconds;
nor with power button down and volume down button for 5, 10, 30, 60 seconds.
Have a run into an permanent apx bootloop? (not sure what that is but doesn't sound good).
Have removed all usb and micro usb drives.
I have never rooted the device; recently did a clean factory install and had it working fine.
When plugged into my linux desktop, I was able to access it. I've created /media/transformer mountpoint, ran sudo chmod -R 755 /media/transformer
and then
sudo mtpfs -o allow_other /media/transformer
but then receive the error message:
"Transport endpoint is not connected"
This is new.
Then travelled to the USA and plugged in device to recharge at JFK at at least 2 places. None of the plugs worked. JFK was somewhat waterdamaged from recent floods. Could this have fried the device through a power surge?
Can't think of what else to do than perhaps let it power down completely and then try again.
Any suggestions would be greatly appreciated.
I purchased the device in Canada and now an living in Morocco so sending it back for an Asus RMA would be very difficult and likely more
expensive then purchasing a new Nexus to replace.
Do I now have an expensive paperweight?
Desperation?
I'm thinking of following the directions found at a tabletroms forums site that I can't post here becuase of xda forum rules, but it calls for "Nvflash Unbricking and forever root!" but would first hope there to be some simplier answer.
I've read a lot of other XDA posts and googled many a version of this question, but nothing seems to help, except, perhaps, for the link above.
Luckily, I always back up everything so nothing on the tablet is irreplacable.
Is it time for desperate measures?
Screen Visible when plugged into a HDMI TV
Going out on a limb, I plugged the HDMI cable into the TV and up pops the screen of my tablet, fully functional, battery levels OK, brightness on full and all working as it should...
...except that nothing is showing on the screen except pitch black.
Next step -- factory reset? or could this by a hardware misfunction?
I'm going to try a factory reset and see what happens. If it does not come back to life, I'll know it's a hardware malfunction and wait until I can return to Canada for an RMA, unless anyone else can think of something?
Factory Reset Did Nothing
... simply now have a factory reset tablet that can be only viewed when attached via an HDMI cable to another screen, while the screen itself, is blank.
Does that confirm an hardware problem?
I'll have to check my warenty, but my bet is that it too, just expired.
From what you described, sounds like your screen is broken.
Lingering Question...
Before turning this over as the tablet attached to the TV so the girls can watch programs from the NAT box; is there any hope that (A) reflashing a new ROM might breath life back into the old girl/tablet or (B) is there a way to do a quick fix via opening up those Torx T5 bezel screws and looking for a loose wire of two (not able to soder something that complicated).
Would that work or am I the one with the screw loose?
Broken Screen = RMA or paperweight?
So if the screen is broken, I either have to return it and hope it's under warenty, or find and replace a new screen (hmmmmm beyond perhaps what I can do) or leave it as an expensive keyboard / mouse with computer capability on an HDMI TV and if you touch the black screen in the right place -- which still works! -- then I can control the external video.

Sounds like a wire has come off or you have what is called a dry joint which happens when a soldered cable doesn't take properly, I very much doubt the screen is kaput
Hi guys,
This problem has me stumped, so I figured I'd consult the hive mind.
The touchscreen works fine after the phone is turned on - be that for a continuous period of 30 seconds or 30 minutes. However, if/when it goes to sleep, the touchscreen becomes completely unresponsive on wake up. The screen turns on, rotates, and the physical buttons work fine. I figure no touch input is acknowledged, because if I tap the screen after it dims nothing happens; but if I press a physical button, then full brightness is restored.
I have been looking around for a solution for some time, but none of the three I found appear to be working, ie:
- Ensuring the Wi-Fi's set to be permanently on (no change on any of the settings)
- Changing the ROM (problem appeared in stock ROM, it now sports LineageOS)
- Changing the digitizer (problem is the same on old or salvaged screen)
At this point, I am not sure what else I can try. Any ideas would be most welcome.
Maybe charger? Some cables/chargers make touch panel go crazy (it used to happen to me with bad chargers) so try to change charger and USB cable.
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
Screen is black and no combination of button input will do anything. Unit will charge and CPU is running since it's sending battery and location data. Unknown if unit may have been damaged/dropped. Have ADB. Help!
The phone is making normal notification and ringing sounds. I managed to locate and run Scrcpy.exe, a "carbon copy" program that lets you remote-in to the unit using a computer keyboard and mouse and ADB over a USB connection.
Invoking Scrcpy.exe I was greeted with an image of the "normal" phone screen (what I should be seeing on the phone's display if it wasn't black.) After about 10 seconds the phone-screen on the computer turned black and I was back to square one. Tried again and quickly used the mouse to trace my unlock pattern, this worked. Using the computer keyboard, mouse and display with Scrcpy.exe I was able to read email, check voicemail, I presume I could do anything I would have been able to do on the phone's touch screen (unknown if the touch screen still works).
Unfortunately I haven't yet been able to coax the phone's screen into displaying anything other than black.
It's beginning to look like the screen is FUBAR -- or is it?
E: The home key, power key, and the touch keys to the left and right of the home key all work. Ran Samsung diagnostics by pressing *#0*# . All diagnostic tests passed except for display and touchscreen.
Will attempt to drain the non-removable battery and try again.
Cured it by draining battery!
The battery was allowed to completely drain and was reconnected to a charger, resulting in the screen coming back to life!
Hooray beer!
