Won' t turn on! Tried all suggestions

Yes I have read all posts regarding "Screen Of Death" issue and i have tried all the suggestions. But still, my 10.1 won' t turn on. I have left it drain the bat for 2 days now.
Even if i plug it to the charger there is no sign of battery charging. Hence just blank black screen. any other idea before I have to go to the Service Center. Thanks. Any help would be appreciated.....

Connect the USB to a Windows computer and press Power + Volume Up for 30seconds. Do you hear a Windows "new hardware found" sound?

Thanks... Tried... Still fail. My PC only signaling found new hardware but fail the installation process. I guess because the tab is still not ON. Help....
It seems my PC recognizes the tab but can't find the driver. I can also feel "warm" near the power button area when i connect it to any electricity but still no TURN ON or BATTERY CHARGING INDICATION.

Have you tried to charge it with the wall charger for at least 2hrs and then unplug it and hold powerbutton 10 sec?

Actually, that is what I was expecting as result.
The Power + Volume Up enables the nvflash APX mode, the screen remains totally black. I simply wanted to know if the tablet works and the culprit is just the screen. From what you say, we get the expected results... Windows detects the new hardware so the tablet works.
Now try the opposite: Power + Volume Down, hold it for 30seconds.
If you don't see nothing on the screen, it is probably a screen contact that got lose... you need to service it by Samsung.

yes done that. Still not ON. When I plug it I can feel it is working since I can feel "the warm" but screen still is blank

Then you already know what to do.
No biggie, Samsung will send you a replacement for sure.

yes. In fact now the APX is still working trying to find " a new hardware ". Should I cancel it and try the POWER+VOL DOWN now?

Yes, go ahead.

DONE the Power + Volume Down still not ON. BTW the APX Could not find any driver? Is it normal. Before this happens in fact i can transfer any file with my PC through MTP. Thanks again for your help. Hopefully you still know any other solution.... Keep waiting

The APX driver is included into nvflash package, it does not matter if you install it or not at this point. The advantage of this test is that the APX mode keeps the screen off in purpose, while allowing you to flash the tablet through a CMD window (only if you have an unlocked bootloader). We used this trick to determine if the core of your tablet works... we wanted to isolate the problem related to your screen.
I recommend you to contact Samsung and have the tablet serviced. Some screens lose a contact point when you drop the tablet by accident or if a soldering point is weak... The heat generated inside is enough sometimes to sever a lose circuit connection. Either ways, you do NOT want to keep this tablet.
I hope you did not flashed the tablet with some custom ROM, or else Samsung might void your warranty.

OK. Then the only thing i can do is go to SC.......Hmmmmm I am still using stock rom but unfortunately i did root the tab already. Is it bad judgement??? Thanks anyway.
I really hope it is only the screen connection lose issue. But just for curiousity. If only the screen keeps OFF, does it mean I actually can still check that my gtalk on the tab still connects? How this thing works??? since i just check with my phone my gtalk on tab is off.

You ordered the tablet online from Samsung or you bought it from a retailer like Best Buy?

I bought it from retailer. BTW is there any kind of USB JIG for the tab similar to SGSII? I just thought maybe this can help solve the screen of death issue. Ha ha ha ....

Perfect, just go see the store and explain to them nicely the issue. I'm sure they will exchange it for you.
Forget about the JIG or anything else, your screen is gone wacko... What you do now is try to force a blind guy drive a car... Just go exchange the tablet.

Ok I' ll do that. Thanks for your info and help. Hopefully problem will be solved soon.

I had the same issue but I couldn't return to the store so I went through support. They don't have parts yet so they just send you a different unit. In total it took 2.5 weeks for me and I ended up with an unlocked unit

Damn, it took 2.5 weeks to get a new unit?

The good news is, it's recoverable. The bad news is, it's going to take a long time.
Keep it off the charger.
Hold down the power button to get it cycling through APX mode while plugged into your PC (can hear the USB connection sound in Windows).
Tape the power switch down, verify it's still going into APX mode after taped, then unplug it.
Leave the tablet alone for a few days. Think about puppies, chocolate, bouncing breasts, whatever makes you happy, and forget about the Tab.
Come back, plug it back into the PC, see if you still hear it connect. If so, walk away again, come back the next day.
When it finally stops going into APX mode, plug it into a wall charger and leave it alone for about an hour, it should start charging normally, and once it's got charge showing, it'll power up normally.
Rule of thumb is it'll take about a full day for every 10% of charge that was on the battery when it went down, if you keep the power button taped down.

Vega Won't turn on at all. Not even backlight

Just bought my Advent Vega today and was all running fine. Charged it too 100% then turned off and booted into the stock recovery. I then waited for it to show up on the computer as i have already got the drivers installed as i have jjust today flashed someone elses vega on the computer. mine didnt show up and then unplugged it and now it wont turn on at all. Tried charging it and then try booting. Unplug charger nothing. The thing is that the charging light still shows.
Any Help would be great. Dont want to have to send it back for repair. it may take weeks.
Thanks
Alex

Hmmm.... it could be a faulty unit, but my guess would be that you need to try at least 10x to try to turn it on.
I know some people complained that the buttons are very poorly designed and sometimes don't even work.
It's the same for my tablet, the "power/home" button doesn't always work like it should.
Once, I had to retry five times in order to power on the device.
If it's not that it could be some other minor issue, try holding the power button for a long time (8 sec), or try to go into recovery again, or something like that.

a sighn its trying to boot is the blue led under the camera tilt the vega away from you and look at the edge of the LCD it will glow when powering on

have you tried push back button, hold it, then press power button 2 second, the release the power button while still pressing the back button? it should be recognized and can be flashed

Some times this can take several attempts.. and i mean several!
I actually had Audi running and had it connected to the pc so could tell if it had worked or not... not the correct way i know but it worked for me.

Interested to know if you ever got this sorted alcurtis93? I'm having the same issue with a vega where it won't even bring up the backlight. No life in it whatsoever.

A bit of a late reply, but try to wipe your device and maybe even flash a newer custom rom

Power button not working after upgrade to 9.2.1.17 / US

Yesterday I have updated my TF101/US to 9.2.1.17 (not rooted, serial B50) and now my power button does not work at all. I cannot either shut it off (I can hold it for minutes, nothing happens), nor can I wake it up (the only possibility is to plug in the power). Reset to factory setting does not help
I talked to Asus, they suggested to send it to RMA, but I want to try to discharge it completely and check whether it helps.
Will keep this post updated if I find out something more.
Update: battery discharge did not fix the issue. Going to send the device to RMA.

Thanks for this post, this if for no other reason is why I will be dealing with my random reboots (they only occur once a week or so, if that often, for me so not a big problem, not like a broken power button would be) rather than updating the patch. However, this belongs in general or Q&A not development

Also for me you have to call assistance for a RMA: i could understand that power button does not turn off screen, but i can't understand, a part an hardware problem, how it does not shut down keeping power button down or why it does not turn on.

Yes, that sounds like hardware issue, but that must be very weird coincidence.
The complete story is that I just received device from RMA yesterday (LCD backlights were broken). I turned it on, it happened to have ICS already (it was sent with Honeycomb) and I was able to install all my software. Then a message re. new OTA update poped up, I decided to upgrade, and right after that power button stopped to work.
Yes, that can be hardware issue as well, that is why it goes to RMA. If I were 100% sure that this is software issue, I would wait some days hoping that ASUS will release bugfix for it.

Hmmm..the device will not power on if it is shut down? (How would you know this unless you shut down, and then can't turn it back on I don't know).
I re-read this and it is unlikely IMO that a firmware update could break your hardware, but I guess if a computer virus can break nuclear centrifuges anything is possible? Could be a coincidence..I feel for you, I had an over-discharge issue one night and my TF didn't want to boot up, and then flashed the red battery on the screen, but for those first few seconds my heart wasn't beating..I get the same feeling when I get a bad flash too lol

Luckily, the device wakes up when you plug the charger in. So, currently my choice is either to keep it running (disable sleep) or to have a charger and plug the charger in when I need to wake it up.
The bad thing is that the RMA "cycle" takes about two weeks.

Maybe it isn't a coincidence..

Mine started this about two weeks ago before I picked up the update today... I thought i was the only one until I saw this post

I have misunderstood something: post says WAKE ON not TURN ON, ok this could be software related, but long press power button should be FORCE A SHUT DOWN...

Click this link on how to remove the front bezel. Then you can check the inside power switch to see if it's working:
http://www.techrepublic.com/photos/cracking-open-the-asus-eee-pad-transformer-tf101/6270147
That's the way I fixed my TF101 after I dropped it and the power button got stuck in the chassis.
Also read this thread:
http://forum.xda-developers.com/showthread.php?t=1391254
I think this is a solution to your problem, if it's not software related, which I doubt.

I get the same problem all the time, I leave it sitting for a couple hours come back and it won't turn on or off...

I also sometimes get the non functioning power button. I cannot consistently replicate it.
Sometimes it happens after it sleeps for awhile.
Sometimes it turns on when I open the tablet up while connected to the dock.
I have to hold the power button until it reboots itself. This is annoying after while. And even getting more so.

I'm also having a power-on related issue since the ICS update but didn't want to start a whole new thread for it. Ever since the update my Transformer boots into CWM by default. If I power it down completely then press the power button the EEE Pad logo flashes on the screen, I hear an audible "click" (best way I can describe it) from the device and it boots into CWM. If I select "Reboot device now" from the CWM menu it boots right back into CWM.
The only way to boot properly now is to hold the volume down/power buttons until the menu comes up to choose between Android and recovery and choose Android. (It actually defaults to this so I can just let it sit 10 seconds or so)
Any ideas?

exactly same problem as me now. holding volume down and power is the only way to start it up if it has been left alone for awhile. since the update.

Apparently it's a pretty common issue with the new version of CWM, as explained in this here thread.
So far the only solutions I'm seeing involve ADB commands or flashing a custom ROM.

fixed for now....
I had the same issue the power button would only cold power off the device. The only way to power back on is by connecting the charger.
I solved it for no in the following way which i do no recommend to anyone. I have opened the device and disconnected the battery for 5minutes. After connecting it back the device powered on with the power button as it should.
In my opinion it looks as if there's some power related controller that was "hang" and ignored the power button .
Any ideas ? Asus ?

[Q] Vega Display not working

I've just bought a 2nd had vega off ebay and it switches on and runs everything (including the touchscreen) however there is no display, the screen just remains black.
I know that everything else works because I connected it to my telly with HDMI and I can control my device looking at the tv (its not easy)
I've reset the tablet back to stock rom etc but still the screen remains black
Is this a duff device or does anyone know a simple way that may fix this?
Thank you in anticipation

If you also don't see Android's and Manufacturer's logo shown when booting up your tablet then I would say that it's dead and need to be returned.
If you have trouble rebooting it, press and hold power button for 9 seconds. It should be completely turned off now. Then hold the power button for 2-3 seconds in order to boot it up. Company logos should be shown now.

Hi thanks for your help. Vega now fixed. I took off the back and reseated the connector and hey presto it now works.

Glad you fixed it yourself!
It just shows that the build quality of Advent Vega and its clones is really low.

Bricked?? Nvidia Shield Would Not Update! Can I Solder/JTAG?

Hello,
I have tried the search feature to no avail in regards to following the appropriate troubleshooting steps to ensure that I can at least boot to fastboot, however I cannot boot into the fastboot menu.
These are the steps I have tried so far:
With only the Power, HDMI, and MicroUSB to USB connected
1) Disconnect the Power
2) Hold Nvidia Button Down
3) Reconnect the Power
4) Release Nvidia Button (~2 seconds)
5) Press and Hold Nvidia Button (~5 seconds)
again, I am still at a black screen with no output whatsoever.
I have also tried allowing a full power cycle (where the Nvidia TV is left alone for approximately 15 minutes)
I also tried the Nvidia chat support who suggested that I try plugging in the controller and pressing the A and B buttons simultaneously, etc. to no avail.
Is there anyway to force a fastboot interaction via console? I would just like to reflash to stock. Even if this method requires altering the hardware via soldering.

You need to connect (Depending on your Model), either a MicroUSB, (2015, 16Gb, Pro / 2017 Pro), or a Male Type "A" to Male Type "A" (2017, 16Gb) between the Shield TV, and some Computer. I prefer to use a Netbook running Win7. But, This should be equally valid for Linux, and Mac.
So with you PC / Netbook turned on, and connected to the Shield TV via USB. Leave the USB style plug in the Shield and if possible yank the Brick (Wall Wort), instead.
Start a Two beat count.... 1... 2... 1... 2... (It would work better if you had a Clock that had a Second Hand.) But once you have this 'beat' drop in the Wall Wort on count Two. And THEN tap the Power Button, hold this for Three counts, than release (Pro Uses might note the SSHD will start to wake at this very moment), and immediately re tap, and hold the Power Button till you enter the Recovery Mode.
This is a very time sensitive attack, and 2/3s of the time will land you at the nVIDIA Logo. (Where available), and your only option here will be to start over again. Or boot completely into Android, and use
$ adb reboot recovery
To force the Device to reboot into recovery mode.

I appreciate your reply but again I am not getting any output what so ever after attempting to apply an update to the Nvidia Shield TV. Is there any procedure to force the device to flash even over hardware?

Depends on if you have a 16Gb or not...
Let's put it this way, if you have a 16Gb it's pretty a wrap. If you have a Pro then you have a few options. Like ripping the SSHD out of it, and attaching it inside a PC running Linux. Or at the least a PC running a live install of Linux.
Which is critical to maintain your private keys. Everything else can be discarded. But, not those DRM Keys. Not if you plan on ever using anything that will need Widevine L1.*
Now that is wholy your choice to make. Either way you will probably want to down that Torrent, which is a backup of someone else's Shield TV. It WILL reserect your Device. But, if you haven't managed to recover your own Keys you will not be able to rewrite them back later on. And, the upshot of that will be the loss of all Widevine L1 Services. e.g. Amazon, Netflix etc...**

I have the 16GB model and I am not sure what would be the best way of resurrecting my device upon a bootloader that is corrupt.

I think your forked... The only way it could possibly be done would be to pull the ROM Chip, and clone this in a not so dissimilar fashion, and then flash a working 'Image' back onto it. Before resoldering said Chip back onto the Mainboard.
Again, Not something just anyone could do.
Look I have no idea how old your Shield is, or if you still have, or have ever had any Warranty Rights to begin with. Assuming that you still had any of these 'Rights'. I would recommend playing dumb, and attempt an RMA, and pray that it works out.
If that also fails, then I guess you are what is termed as being SoL...

Thanks Ichijoe I tried to also to boot into recovery using alt + print screen + i (on an external keyboard) in order to restore the device however this did not work.
I wanted to pull the ROM chip but I don't know of any software available to allow such a feat. Does anyone have any information on utilizing J1D1 or J1D2?

This is getting oh so over my head now. So take it for what it's worth. But, as I understand it One would need an EEPROM Programer, and the "Software" would just be written as a RAW Data. Again not entirely, not unlike taking a certain 'Raw' backup that someone tossed up to the Net as a Torrent File. For bricked Pro users.
Pulling the ROM Chip off the Board is not something just anyone can do without destroying the Chip, the Mainboard, or both. The EEPROM Programmer is also an additional cost, of which I would have no clue. Needless to say, in the long run it's just unfortunate as it is, to just get a new Shield.

let's try this way :
unplug your power cable of the shield tv
plug your lan cable on your shield tv ( be sure DHCP on your local network is turning on)
plug your new shield controller on the usb port of the shield
plug the power cable and DON'T TOUCH THE CONTROLLER for 1 minute
now hold down home button and left button ( on the X) for 3 seconds
normally you can see the blue signal of the controller 3 times. this mean the procedure working good ( if not retry till it work)
now let your shield working around 2 hours ( depend of your download speed)
afetr this time, normally the shield finish downloading the update and restart... now you normally can see the screen
