Situation

• Mavic 2 Pro,  Smart Controller, and two batteries that have not been used for many months.  I wasn't aware of the battery maintenance procedure so I suspect they all went into a hibernation state.  
• One battery is completely dead and won't charge on the original DJI charger
• The other battery charged up fine
• Smart Controller charged up fine
• M2P powers up fine with a good battery.  Solid red lights on the front, alternating red, green, and yellow blinking lights on the rear
• After a few seconds, the rear lights change to blinking yellow
• Power up the smart controller with one short press followed by a long press
• Smart controller battery lights illuminate one by one then show four solid lights and a single red (pairing) light
• After a few seconds, the red light on the smart controller changes to green, and at the same time the rear lights on the M2P change to blinking red and yellow.
  

At no time does anything appear on the smart controller screen/display.  It remains black.

The smart controller will only power off using a short press followed by a long (reset) press of the power button.  I've tried all of the reset combinations listed in the forums i.e. C1, C2, Snapshot, Power buttons etc but none of these fix the black screen/display

The M2P is recognized by the DJI Assistant 2 but the smart controller isn't.

All of this equipment has only been used a few times since purchased new - no crashes or drops.

Any ideas?

Hi, Mcassellis. Thank you for reaching out and we're sorry to read about the black screen you're getting with the Smart Controller. We appreciate you giving detailed information. I would like to verify if the black screen is happening on the image transmission screen only or even on the home page as well. Does the light stay lit up and solid green under that condition? We will wait for your update. Thank you for your understanding and cooperation.

Hi and thanks for your reply.  The smart controller screen does not light up at all.  I know the SC is powered on because the battery and link lights are on and because it appears to link to the M2P when it's powered up.  The link light will stay solid green with the drone powered up.

Hi and thank you for your suggestions.  Yesterday, I received a shipping label from DJI to send to their service center so there's no need for me to do any problem determination.  I will come back with an update when I have one.  Thank you for your help.  I really appreciate it.,

Hi there. Thank you for the update. Please don't hesitate to reach us if you have any inquiries or concerns. Thank you for your valued support.

Hello! Very similar issue out of the blue this week with my DJI Smart Controller and Mavic Air 2. Flew multiple times as normal they day before. Charged all gear. When I tried powering up the controller the light sequence is normal, but the screen will not turn on or show anything. I've tried multiple tricks in these forums - holding down a combination of buttons, etc. Still cannot get my smart controller screen to turn on or respond. Any advice?!

Hi, djiuser_dpmBcFMnZkSD. I have sent you a PM, please check. Thank you.

I'm also experiencing the same issue.  Yesterday I got a new controller and updated all the firmware as prompted on the device.  Today I went to turn it on and it connects to the drone, but have a black screen.  In post 4# I downloaded DJI Assistant 2 to my PC and connected the controller to my PC, but it won't find the device.  I've tried multiple USB ports and also a different cord.  Any assistance would be appreciated.

Hello there. Sorry about the inconvenience. If I may ask, may I know which remote controller are you having a problem with? Have you already followed DJI Gamora's suggestion in reply 4#?

Same issue black screen. Bought this for Hawaii trip and here I am and what a bust this drone is. Nice job dji. No footage of my trip. I will be returning it when I get to the mainland.
