Nvidia Shield Pro (Has Power, no Video) - Shield Android TV Q&A, Help & Troubleshooting

I recently went to use my Nvidia Shield Pro (500gb) and the unit powers on and stays on but there is no video or image displaying. I've tried it on my 4K TV, PC monitor and a 720P monitor, different cables, and still nothing. I've gone through the different procedures to reset and get into fastboot and nothing has worked. When I connect it to my PC or laptop to try and get into fastboot, I am not sure if it is being recognized as I don't see anything populating on the PCs to show that it is connected. Are there other procedures to hard reset? Is there somewhere I can send it for repairs? Thanks!

same problem : ( any solution ?

Same problem, just happened this week. System was working fine, then one day turned on, the system lite is sold green. No picture on the screen. Unable to access safemode or fast boot.
Last update installed a was a few days ago before the issue.
I have no mods or unlock. My systems is 100% stock Shield TV Pro 500gb

Happened to me last night. Black screen on my 4K TV, but it works fine on my other 1080p TV. Nvidia customer support claims there's on known issue, but it's coming up on their forums as well...guessing it's a software thing?

Had the same problem but no video also on a 1080p TV I contacted customer support and got a RMA done on my unit.

Hmm... interesting, my dads is doing the exact same thing... Anyone find a solution yet? I get no video and solid green light. I have tried everything I could find online to get into fastboot or whatever but no luck.

My 2015 Shield Pro died a few days after the 7.2.2 release. Not saying that was the problem, just that was the timeframe.
I can turn the unit on by unplugging the power brick, then reattaching power. Green light turns on but doesn't drop to the lowest brightness after a bit as previously configured. Has no HDMI output and can't hear the fan nor the drive spin up, doesn't respond to pings.
What I can do though is turn off the Shield by holding down the power button for six seconds. Remote and Controller, no effect.
Out of warranty and I haz a sad.

Same problem powers on and off, green light lit but no display, when I hook up to pc it shows apx

Hello,
i got the same problem, powers on and off, green light lit but no display, when I hook up to pc it shows apx !
I searched a lot and did not find a solution. It must be a software problem.
I hope that more people with the same problem comment on this thread !

in my case it is the ribbon cable (the HDD is not powering up)
Sadly I haven't found a way to buy this POS https://item.taobao.com/item.htm?id=537879306182

ribbon cable is just not good enough to provide power to a hdd over time. swap that drive out for low power ssd

I have a 2017 shield tv with this problem. Plugged in the green light comes on then nothing after that, no change at all on screen or to the light. I have several Shields and swapped things around, working cords, power supplies, working game controller, working USB keyboard etc. No fast boot and my computer does not recognize it when it is plugged in to it.

Transformer Bricked Itself...

Well I have a expensive paper weight lol. Last night the TF wouldn't turn on all of the sudden. It had a black screen so I figured the battery was just dead. This morning the alarm goes off and the screen is still pitch black.
No backlight, no LCD (I hit it w/ a flash light, can't see anything) It will power off and back on, I can tell because I lose USB connection if I hold the power button, then hit power again the camera will click and I'll get USB back in a minute when it reboots. Sounds like a dead screen I know but when I get USB connection I get under My Computer "Transformer TF101, Portable Media Player" and no hard drive. I can open Transformer TF101 but there's nothing inside, no access to it's internal SSD.
I'm installing abd now and going to pop a SD card into it but in the mean time any ideas? What abd commands should I run? Never used it before. I'm just outside the 30 day window of Newegg which suck so bad.
Have you tried holding the power for 10 seconds to hard power it off?

If you arent even getting the start up screen adb isnt going to help, RMA your tablet.
Yea, it looses USB connection, then I can hit the power again and get USB back in a minute.
Edit: The alarm went off this morning so Android is def running when it turns on.
Doesn't sound like you're bricked, more like your screen is dead.
Sounds like a trip to the land of RMAs to me.
Yea screens dead. HDMI works and the internal storage wasn't working because my screen was locked. RMA time...

My tablet doesn't turn on again

Hi, I start this new thread as a new user and my first message because I'm really really worried about my samsung galaxy 10.1 tablet, It is a wi-fi only tab I bought through Amazon, and has just arrived to my country, Costa Rica, so, as any normal person, I opened the box, readed the manual and turned it on, and started checking everything in the tab, and when finished, (because I don't have wi-fi yet) I turned it off, and started to charge it with the factory charger (AC conector) it has been 5 hours since then... It has not turned on again, no matter if I press the On button 30 seconds, nor turning it on conected to a computer, or to the AC, or without anything, so I called support, and they said the same thing I was expecting, charge it and see what happens, and nothing happened, I'm really really worried about my tab, 600$+shipping is a BIG amount of money to have invested, the computer is brand new, as you will buy it from the second link availabe in amazon when you type samsung galaxy tab 10.1.
Can you help me?
Tab does not turn on..
What finally happen did it turn on...If not there is a why to reboot it by holding the vol. button and the Power.
Hope it went well, don't give up..
That is why I made this thread, I already tried the volume technique, with +, with -, with both, with + and shaking, with - and shaking, and all those with also touching the screen, an nothing!!
when you turned it off and plugged it in to charge, did you notice anything appear on the screen indicating that it was charging? Normally when turned off and plugged in a battery will appear on the screen. even if the screen turns off you can touch the power button to show the battery again.
If no battery ever appears, then it looks like you were not receiving a charge in the first place so the tab can simply be dead of juice.
Yes, the first time I turned it on I saw the battery, but when I turned it off, I never saw it again, even in this 10 hour period that has been charging on different outlets to see if the outlet is the problem.
Even I used a pencil tipe voltage tester, that tells if an outlet has voltage current, and the voltage could be felt around the tablet when charging.
But the screen does not turn on when pressing the button, nor touching the screen.
as a test, use just the usb plug and connect it to your computer. it shouldnt receive alot but see if that will initiate the screen turning on displaying the battery.
No, it does not turn on even when conecting it to the computer, it appears a message of no controlers found in the computer, but the divice does not turn on at all

idk then man, it could be the wire or it could be the tab itself
Besides something wrong with the GTab, I guess it could still be a defective cable.
Yes, it could be a possibility, that the wire is bad, but also, I can mention that in the time it was on, and working, I exchanged a couple of photos for my wallpaper, photos that I took with my camera long ago, so, if conection means, the cable I think works ok.
this happened to me.. tab is finished, send it in for repair and you will receive a refurb....

Did you press power and volume down at the same time for at least 31 seconds for samsung logo to come on?
Sent from my GT-P7510 using Tapatalk
I've tried with the volume key and the power key at the same time for almost a minute, without being conected to the charger, and being conected, also tried conecting it to the computer, and downloading the drivers that samsung offer in the support page, and samsung kies, but they don't recognice the device, when checking the hardware of my computer, I see inside the tab of "other devices" one called APX that I know that is my tab, and says no controller is assigned to it.
Mackie, yesterday (today) I chatted with a support agent of samsung until 2am, trying to see for a solution, but he couldn't find one, so, we ended up in making a request for service, to use the warranty for them to repair/give another machine to me, but, I don't want to do it, because, it would be enormously expensive for me (100$ for a Costarrican is very expensive) so, I'm trying to find a solution to the problem before I send the tab to the US with a friend that lives there, so I can use the warranty, but that courrier charges would be really expensive for me.
In summary, I'm trying and trying to look for a solution, testing your comments and suggestions, and also at the same time looking for myself for an answer.. before december 8, when I plan sending my tab if anything works.
Once, this happened with my nokia e71, but because it ran out of battery, and won't turn on again, but... cellphones are easy, you can change the battery, and actually, it worked, and when I had time to take him to repair, they checked him with the old battery, and it worked again... Tabs are horribly sealed tight and I would lose the warranty if I try to open it to change the battery, and it might even not solve the problem!
i don't know if this would help.
I had the same situation and i thought mine was dead.
I pressed the volume button as long as i can. Took about almost a minute.
Sorry if this doesn't help
people please read previous comments, Coliner has stated numerous times in different posts that he has tried the power+volume method and has had no luck so please stop suggesting it
Coliner, the only other thing short of paying the money for the exchange/repair is to attempt using a different cable. you stated before that you used both the usb partial charge and the actual A/C charge method and have received no results. The only thing I can suggest is to try a different cable, if anyone else you know has pretty much any of the galaxy tab (7", 7+, 8.9", 10.1", 10.1v) then you can attempt to charge it. Or hell, see if any store has any of them on display charging, explain your situation and ask to let you give it a shot and if it works buy the cable from them if possible.
Short of prying the thing open to play surgeon, these are your only options.
NyPlaya, today, I'm going to the capital (the only place you could find something similar) and look for stores with tablets, and also directly to a samsung store, ask for a charger, and to see what happens, and try again to turn it on at my house, I've let her charging for 2 days now, continuosly, lets hope it worked!

I re read your post and i think we missed a big clue. You said you can see APX device in control panel. Apx is nvidias debug mode and in this mode (usually reached via power and volume up) the screen is blank. it is waiting for nvflash command. Check this thread for more info http://forum.xda-developers.com/showthread.php?t=1324461
So wonder if volume up button might be stuck
Sent from my GT-P7510 using Tapatalk
Well, I tried the procedure, and got to step 17... How do I run that command, how, where? so I then uninstalled the controler, and now not even the APX error appears, and tablet is still dead!
Also I went looking for chargers in stores, and they did not have chargers! so I couldn't test it!
I was searching in other forums and found this other clue:
Taken from http://www.htcmania.com/showthread.php?t=274687 post #14:
"What you run "dead" after having it at night charging, is something that unfortunately is still quite common. It happened at the beginning and pulled by soft reset, ie power button volume button -. It has happened a few times and this has been solved. I think it is related to removing the charger. Unplugging from the wall and then the tablet does not usually fail, but if you disconnect first tablet, it "dies." I tried also to turn on the screen before unplugging and so has not failed me to unplug the tablet first. Clearly a bug, I do not know if Samsung or Honeycomb, but obviously it is a pretty annoying bug. regards"
I remember I did that same thing! because my tab was conected to the PC, and I discovered it was not charging, I conected her to the AC in the wall, and without taking the 30 pin conector out, and boom, never again it has turned on!
I continued searching and found another method, power button plus volume- 10 seconds, release and volume + for some seconds, then conect to PC, and the driver appeared again, in this case Nvidia USB boot recovery
I continued to try the method shown to me by animatechnia, and typed nvflash --bl bootloader.bin --go, it says then:
Microsoft Windows [Version 6.1.7601]

READ THIS, IT'S HAPPENED TO ME
Shortly after buying my tablet, before rooting, my tablet was charging and would NOT turn on. I read somewhere to do this:
Put your finger on the screen while holding the power button for as long as you must.
Don't let go til it comes on.
Edit: best of luck if that doesn't work. Things like this suck.
First time I tried with the finger, I forgot to disconect it, so, my pc started making sounds of conected device, disconected device, just like an USB stick, then I took the cable off, and tried for more than a minute both finger and power, and nothing happened

[Q] Nexus 7 dead?

I was on my computer when i remembered i has something written in my tablet's notes that was important. I took it out of my bag and noticed it wouldn't turn on, it was out of battery (hadn't touched it for about a week). I just plugged it in the proper asus charger and put it down and went straight back on my computer.
I decide to check on it after 2 hours thinking it would be near or fully charged. I pick it up and noticed it was on a blank back lit screen. I unplugged it and then the screen turned straight off. Wondering if it didn't charge at all i re-plugged it in. There was no google logo (rooted), instead it turn on with a lit black screen and off and repeating a few times and then small thin artifact pixels run across the screen (red, blue and yellowy colours) and then stay at a black lit screen like when i first picked it up. I had just noticed a small buzzing sound while this was happening and still does so when stuck at the screen. I'm pretty sure it was buzzing when i had found it.
I redid what i had done (unplug, replug) and watch to see if it did the same thing. It did. I tried to power it off while it was at the black screen and it did, but then it would turn back on and etc. Same if i tried to enter boot loader or any key combinations.
I've tried disconnecting the battery and reconnecting and same effect (tried it without battery attached also)
I have a feeling it is dead now and i have no other ideas (checked many forums but got nothing).
Any help would be appreciated.

It's surely hardware failure, have take some humidity or something like that?
Try press power for 60 seconds, if you wont see any Google logo there's some hardware failure you need to RMA ( http://en.wikipedia.org/wiki/Return_merchandise_authorization )
found the fix
I found away to fix my nexus 7. You could be right how it might have a minor hardware fault, live in australia in the high hot tropics (high humidity). I decide just to plug it into my computer usb charger instead of the proper charger since it had a lower max amp output. Against my ear, a much fainter buzzing is still heard but this time, there was nothing. No power, no back lit black screen, just a very faint buzzing. Decided to let it sit just to see what happens. After an hour or so, i decided to press the power button and noticed there was a battery charging signal. To my delight, I'm sure it was in working order now so i powered it on and oh how relieved i was.
I determined that my device might have had a small hardware fault that made it draw to much power from the 2 amp original charger and thus why the tablet could not boot up properly (from battery depletion). Either that or my charger could be bugged to. But the thing is, since it charged to slow from the usb, i plugged in the proper charger and it worked fine. Just have to try not deplete my battery i guess.
Thanks.

If your controller wont turn on

Charged my contoller overnight and today it wouldnt turn on. This scared me and thought my contoller broke. After googling I found a fix.

Basically hold the power button for about a minute. Mine took about 30 seconds and it turned back on.

You're the man, I also noticed that holding it down for a minute didn't work, so what I did was hold down the symbol and plug it into the charger and the light came on. Thanks a lot for this bro!
lol thats how you pair them anyway...no?
i have a seperate issue but just as i started writing this i think i know the solution lol. my nvidia shield tv remote (not controller) stopped working months back but i think i read that it connects by bluetooth so as i have sixaxis paired to my ps3 controller automatically at boot im guessing this has over written the bluetooth i can use to connect the remote
My god, thank you so much !
There is also a "factory reset" type feature. If you hold the home and back button for about 30 seconds. You will then have to re-pair the controller to the shield.
Also, if your controller Nvidia logo lights up, but the home, back, and play button do not power on, holding the logo button for 15 seconds or so will fix that issue each occurance. Temporary fix to the problem of unknown cause!
Well, I have a problem. For 2 days now my Shield controller is no more paired to the Shield TV.
That only works on USB but no more in BT. And when I try to pair the two devices there is only lights flashing.
I have try your advice for reset the controller, and I have updated it on my computer but nothing change...
Does someone have an Idea please ?
I had a similar thing a few weeks back. I thought it was dead but after leaving everything unplugged over night and then repeating the pairing process (for the 50th time!) it just worked again suddenly.
I had the same problem with my nVidia Shield TV Pro 2017 after I turned it off. However, after plugging in the game controller and leaving it in for about 10-15 seconds - it starts up on its own. No need to do anything else. Clearly this device was not meant to be turned off under normal circumstances

[Shield TV Pro 2017] Device potentially bricked after changing HDD for SSD

Hello,
I've potentially bricked my Shield TV and want to see if I can salvage it from it's current state.
What have I done to the device
I unlocked the bootloader
I opened the device and took out the HDD
I replace it with an SSD (which data i cloned from the HDD)
After that the Shield TV wouldn't boot up. I connected the old HDD to no avail. The HDD was working fine before.
I know can't get the device to boot up in fastboot. It still turns on, as indicated by the green led.
What have I tried
Cold booted the device (turn it off and seperate it from power for 15 - 20 minutes)
Used the controller (Pressing A+B) after inserting the power cable to get into fastboot. Controller rumbles. Nothing happens afterwards.
Hold the "power button" on the device for 5 - 6 sec to get into fastboot. Doesn't work, just turns the device off.
Connected the Shield TV to my PC and then try to enter fastboot. Device is detected by Windows as "Unknown usb device". "Windows has stopped this device because it has reported problems. (Code 43)"
I'm pretty stuck at this point. Is there any know way to revive my device?
Or is it simply bricked beyond repair?
Best regards
Same thing happened to me. Nvidia support emailed this procedure. Worked for some, not for others.
-> Unplug all the cables and keep the device off for good 2-3 minutes.
-> Plug the Power cable, controller through USB (Wired) and Ethernet cable to the ATV. Do not connect HDMI cable.
-> The device will power on. Keep it idle for about 5 minutes and keep tapping A button on the controller. Continue tapping for about a few seconds.
-> Now leave the device is this state without the HDMI cable for good 15 to 20 minutes and plug the HDMI cable.
-> See if the ATV displays any output
