So I bought a standard issue MHL cable for me One X and I hooked it up last night to an HDTV when I got home from work. Worked just fine, zero issues with it.
Wake up this morning and I try the same thing, I just plug my phone is to the same connection set up I had going on last night and now my phone decides it doesn't want to output over MHL...
You hook it up and red notification light comes on, so I know there's power coming through it at least, The screen goes landscape and for a split second I get an image on the HDTV and then message comes on the phone that says "Sound Enhancer not available over HDMI connection" and goes back to portrait. If I leave it plugged in, it will do this in a loop.
I tried force closing and disabling Sound Enhancer app but no luck. Also tried different HDTV and no luck. I'd hate to think the cable's bad...
Any other ideas? or anyone else with this issue?
Running CleanROM 5.1
Problem Solved
So After letting it go for a little bit, I decided to try hooking stuff up like I did the first time. Which was: plug HDMI MHL connector into TV, Mini-USB into phone, power-USB into TV. When I was doing this the second time around, I noticed that the image came on the screen from my phone no problem. I hadn't even plugged the power USB in yet.
Simple fix, yes but it made me wonder because I had thought that the whole nature of the MHL HDMI connector was that it required an external power source (in this case the power-USB) in order to output the image. Though I guess through this little experiment, it seems its only optional if you want to charge your phone while outputting an image.
After I got the image up on the screen, I tried to hook up the power-USB into it and as soon as I did that it started erroring out with the Sound Enhancer crap.
Some kernels now offer the ability to power it without needing an external power source.

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
Hello Gentelmen,
I am rather new to android dev but seassoned in linux, i decided to convert my old phone (samsung admire) into an in dash computer.
I am using two basic applications:
* Torque OBD2 Connector: This connects to the car's OBD2 Port, reads the computer and displays information on screen (like HP, Torque, Manifold Pressure and temp, Boost ...... )
* Autoguard Blackbox: This app acts as a CCTV recorder taping my driving and saves it in case of accident so i can have video evidence.
I have modified the andoid system to open both applications on boot and on external power and to kill them when external power has been disconected. Also when external power is disconected phone will wait 5 minutes then go to sleep. (yes i realize there are apps for that but i like shellscript)
This means that when the key is turned and the car is on recording automatically begins and my gauges come up, when the car is off they close AND STOP RECORDING and go away without any kind of interaction on my part.
The problem: Whenever the car turns back on, external power is connected and i would like to have the phone do a full boot so that my scripts kick in,however instead it goes into charge only mode where it boots in to some kind of "hybernation state" that only displays the battery charge in the middle of the screen.
I would like to bypass this and have the phone do a full boot whenever the power is connected.
I have searched for weeks and have found nothing but people withthe same problem and solutions that involve harware and wiring and soidering however this is not an option for me because the phoen is exposed (not actualy insidethe dashboard)
I am not afraid to compile a custom rom and have it run on the phone ... the phoen is solely for the propose of having the dashboard display. (i dont use it for calling)
Could you guys point me in the right direction?
Thanks in advance.

Hi mates, yesterday I've made a change for 7 inch galaxy tab 2, 8GB, more specially the p3110, as well as I rooted it and updatet it and about 6am insomnia makes me take the tablet, So far so ordinary ...
well then turn it on and tells me that my sd is empty Nothing, I lost the data and I am about to make clear the sd, pretends to format and passed 15-20 secs it power off.
I get out of bed and went to connect it to the wall charger, knowing as sometimes if you leave the battery holding power and swiping your finger across the screen some time reappears stack and reloads it, I do it today that should have full charge and nothing, doesn't returns, when I connect it usb pc and when I do turn on the tablet it sounds windows connected usb sound and at the second connecting it disconnects device again, and there will end up pressing the button again
I removed the back cover and I have even removed the battery about 2 hours, reassembled and still doing the same ....
Summary: Does not display anything on the screen and battery charging even having tried the method "samsung" when this happens, (which only have it, with its official android I had to do it once, and recalibrate the battery even reach 4000 and mark its 100%, hence looked last longer and it was when the update and was working fine about 3 hours with it, no problem opening emails looking face and such, nothing out of the ordinary, there is no heat either, doesn't gave any fatigue sign and the battery was at 80% when It turned off suddenly), when you turn the computer connected to the usb nothing still while connecting a second and off the next, only once, until you return to try give the power or any combination, whether recovery, download, nothing shows anything on the screen
however when I connect it to pc to it hears something in windows, that tells me that the board is not dead, and the lcd was working ok and absolutely have any shot.
can you think of anything? I'm already crazy with this ... odin doesn't sees it, that connects the second and still sounds the little sound of I connect I get disconnected every time you try to pull it out, hopefully a recoverable semibrick at home or less silly ...
still nothing??

What exactly the problem?can you tell us in a lil bit short
post it in
GENERAL CHAT!! All XDA'ers Welcome (noobs included)
maybe this might help....discussing with others who faced the same....and how they solved it :fingers-crossed:
ask your problem in the above thread
and dont make a whole thread buddy....try keeping the general section clean
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.
Hi,
Last night, I put my S6 onto ultra power saving mode before I went to sleep. All the settings were turned on but when I proceeded to my homescreen, I still had all my third party apps on the screen. The phone then froze and I couldn't navigate across my homescreen and my notification bar was stuck.
I manually restarted my phone and then put it to charge.....but it didn't charge......:crying:
I fiddled around with the USB port, tried a different charger, tried a different phone (and it charged without fail).
For some reason, wireless charging still works which moves me onto the theory of a hardware problem. I also put my phone onto safe mode and it still wouldn't charge, so clearly it wasn't a third party app.
I'm not 100% sure yet, but it appears that my phone might faintly be charging while its turned off.
Does anyone have any theories (and solutions) to my problem. I may end up factory resetting but I'm trying my best to avoid that. I still firmly believe that it is a software bug as the phone froze while I was changing the battery mode and that's when the problem arised.
Many Thanks

Sounds as Hardware Issue for USB Port , ok bro ,
is your phone recognize when you connect it to pc ?
are you tring to use different cable for charge ? may be problem in the cable not the charger .
if you are try another cable and the problem still exist so last hope to make factory reset and see if the problem will solve or not , don't forget to make backup of your data first .
i advice you to go to Techanical Shop and check your usb port .
