[Q] Transformer TF101 Will Not Turn On, Boot, Nothing. - Eee Pad Transformer Q&A, Help & Troubleshooting

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

[Q] Question about reset switch

Hey, all.
What does the internal reset button actually do? I was expecting it to reset to factory settings, but fortunately for me it didn't do this. I'm actually happy it didn't, as it means I didn't lose any of the customizations I had done or applications I had installed.
I just cracked open the case on my gTablet and pressed what I assumed to be the reset button, a tiny little white switch in the center of the unit. After pressing and holding it for about 3 seconds, the tablet immediately powered back on and returned to its previous state. Everything appears to be functioning perfectly normally and exactly as it was before.
What does the reset button actually do? Do I need to worry about battery meter not being accurate or any other weird side effects? I only mention that because the battery gauge is showing 100%, but the external red charge light is still on.
I'm not sure what prompted it, but earlier today, my gTablet went blank and wouldn't turn back on at all. My son had been playing Angry Birds for an hour or so and I had been using it heavily showing it off to my in-laws, so I thought perhaps the battery had simply gone dead. I had not plugged in the charger the night before, so it seemed to be a reasonable explanation.
I plugged the charger in and the external red light was visible, so I let it charge for a little while, then tried turning back on. I could press any number of different key combinations (power & vol+, power & vol-, holding button for long time followed by short press, etc.) but I got nothing but a black screen. There was no indication whatsoever that anything was happening.
I was assuming something had gone quite awry, but didn't panic. My wife was not quite so calm, but I reassured her that I would be able to find the answer on the XDA forums. Thanks to everyone who has contributed to this great community, by the way!
First, I tried plugging in the USB cable to my Windows 7 laptop and heard the distinctive 'bing-bing,' notifying me that hardware was recognized, so I knew it wasn't dead. But, it didn't show up anywhere, so I checked the Device Manager. Interestingly, there was no yellow exclamation mark anywhere, as I expected from reading some other posts about NVFlash. I finally found it listed under the 'Disk Drives' section as: 'NVIDIA Tegra 2 USB Device.'
I remembered reading about people experiencing problems with the unit going into APX mode, but I also remembered reading about the internal reset button on the gTablet. So, I figured before I attempted to use NVFlash, I would try the reset button first. Fortunately, these devices were designed well and the case was very easy to pop off.
By the way, I was running the stock ROM, but with the TNT 3588 Enhancement Pack (Gapps with nVidia Drivers) provided by edirector. I had also installed the z4root application. I used the default ROM for the first day, but was comfortable with the idea of flashing othe ROMs, as I've done it with my HTC Aria phone. I flashed roebeet's TNT Lite 4.40 and used that for several days before going back to the factory ROM with the enhancement pack.
Thanks in advance,
Calvin
Well,
I've been reading these forums since last November and I don't know of anyone who
has really reported on "pushing" the reset button before!!!
Usually when people crack the case to push the reset button or unplug the battery
for 10-15 seconds it is a situation where they can't get the machine to start and
literally have nothing to loose.
Sounds to me (in terms of 30+ year of different computers) that you did a hardware
reset and boot. I assume something was locked up inside and the reset key released
it to restart.
Glad for you!!!

screen turning off issue

i just had an episode of an issue that worries me.
I had the tf700 docked and put to sleep by closing the keyboard/tablet. 8 hours later, I pressed the power button and nothing turned on. I thought somehow the battery completely drained, so I plugged in power adapter and still nothing. I tried holding down power and nothing.
Then I undocked, and plugged in ac adapter. After holding down power button for quite a few seconds, i get th screen to come on and the message to confirm tuning the unit off. Apparently the unit has been on but the screen off.
After I rebooted, I find the unit sluggish as if I/O issues again.
I am on firmware .26 US latest. It has been fine until now.
My biggest concern is that I remember a friend of mine describing this issue with his TF101, and said the only way to get it back on was by plugging in the power adapter.
Anyone else can shed some light on this?
I've had this on my SGS2 a few times, and on my previous phone (LG O2x as welll) -- in both cases it was related to issues with deep sleep (and on the SGS2 standard custom kernel undervolting), implying that changing kernels would cure this (or make it immensely worse, hahaha ). Having said that, I do recommend following this issue closely, and if this happens again, I'd reflash .26 from a full wipe. If it then still does it, I would suspect some hardware issue.
Again, to at least provide you a bit of reassurance: I've never encountered the error on my SGS2 again after flashing a (very, very nice) kernel, and the O2x only does it very infrequently now (but has crappy kernel development, at least when I checked last, so I'm still not very satisfied. Might tryCM9 with it or something...).

Before doing any of that I would do a "cold boot." That can solve your problem in its entirety before having to use drastic measures.

what is a cold boot?
it has only happened once, so its probably infrequent. However, I am more afraid of the inopportune times it cn happen. What if it happened when i am away from home with no ac adapter, like on a plane? I won't be able to boot then?

Here is how to "cold boot" (copy and paste from other thread), should resolved your issue.
1. Press and hold down “power button” until the system shuts down.
2. Remove the SD card from Eee Pad.
3. Press and hold down “Volume down” button first, and then press and hold down the “Power” button until the screen appears with 2 icons, one is a droid and one is wipe data and upper left corner should said cold boot linux.) now let go your fingers. Make sure do not press any buttons until the screen mentioned screen appears. If you don't see the 2 icons in the middle of the screen re start from step 1.
5. There’s a line “Press <Vol_Up> to execute, <Vol_Down> to cancel wiping data. Press Volume Up button to execute the “Wipe Data”.
6. After the “Wipe Data” process is done, it will reboot automatically. Then Eee Pad should be able to enter the system successfully.
oh, so cold boot means wiping all apps? have to reinstall everything from scatch r use ttanium backup?
Hi, just wanted to add, happened to me also on my tf700,... I tried factory reset, didn't help, then I tried buhohitr advise of doing a cold boot wipe and that seems to be good.... is only been one day since I tried it, But so far so good... and yes, a wipe does delete your apps if you do a proper wipe.
Thanks!

Problems with Nexus 5 screen

I apologize in advance if this has been posted before, but i have had a look around and cannot see anyone else with the same problem.
I also apologize if I this is not the correct format, this is my first post here :X
My brother brought my phone to me last week with a problem with his screen (shown is this YouTube video at the start: (this is the link following the youtube.com/ part) watch?v=4pks4idq4YI ). I fixed this by hard resetting the phone and it was fine for about a week. Today, he brought it to me and the screen was like this: (this is the bit following the imgur.com part ) /MK6eJdD . The screen reacts and changes slightly to touch, and the power button turns the screen on and off. If i press and hold the power the phone turns off and vibrates (like normal, just without the choice saying power off etc.). When turned on (by holding the power button) the screen instantly returns to how it was before it was turned off, just a different shape/pattern of the stuff on the screen.
I would like to know if i need to replace the USB flex cable to fix the problem. I am fairly confident that i can do this, (as i am doing DT and electronics for GCSE), and so, if possible, I would also like to know where i should buy an official one (if this is indeed the problem). I am in the UK if that helps with the decision .
Thank you in advance,

TF101 does not display on screen (through hdmi output works fine)

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.

Tesco Hudl 2 boot

Hi all. I've been given a Tesco hudl 2 that has turned into a paper weight and basically tesco have washed their hands from it.
It has a common error 'No boot device. Hit ok' - but there is no response from screen or power/volume buttons to enter 'ok'
I plugged in a usb keyboard via OTG adapter and pressed enter which takes it to Boot Manager - with sub menu - Boot Options Menu
but there are no options to select and pressing enter just flashes the screen.
I have tried the factory hard reset option and doesnt work. Just turns on and turns off.
There is no charge light when plugged in, but does turn on to, again 'No boot device. Hit ok'
There is no adb access
I absolutely hate wasting tech and like to use them for other uses. Anything that can be done here?
Is the motherboard blitzed someway.
Anyway to flash a rom via SDcard or force some sort of bootloader access or recovery?
Can the rom be flashed with hardware directly on the chip (tho I don't have the equipment, just a query).
Its suppose to be a good enough IPS display with 1,920×1,200.
Ok now for the out of box ridiculous thinking. Can the mainboard be replaced with another brand of tablet with perhaps better specs.
Can these LCD panels interface with other systems at all, to perhaps a laptop via some sort of display board for a possible car project?
A lot of questions, but hope someone can shed some light. I love finding things out and fixing things, if possible.
Thanks
bump
I have replaced a dead hudl2 charging port and battery all i am getting is a faint green light but not always. however still not booting any ideas please
