I can not get the CrystalSky 5.5 to work very well on my Phantom 4 Pro.  It resets often.  It works perfect on my Mavic and works ok on my inspire with very limited range then I will loose my feed.   My p4p plus never really worked well with the built in screen so I purchased the standard controller and it works perfect with the iPad pro but terrible with the CrystalSky.  All firmwares are up to date and reset many times..  I even sent my p4p in for repair and received a referbished unit that was still logged into the last owner and had a broken UV filter on it.  Still the same problem.    I have also returned the CrystalSky for a replacement and have tried 3 different mounts.  I have turned wifi off and no cell phone near by.  I tried the online support  with not mush help.  
Any feed back would be great.  

Videos  show the resetting.

Thanks

Two things to at least try for the P4P.
Test while using a USB to micro USB on the side of the CS.
Downgrade the firmware on the P4P if possible.

For my Mavic it seemes that the quality of the cable does not matter.

Thanks.  I will try that.

I don't see that I can downgrade the firmware in DJI Assistant.  I will most likely just cancel my CrystalSky Ultra order and sell the 5.5 CS and just use the iPad Pro.   Bummer

Can you refresh the current firmware?
Maybe a firmware update on either the P4P or the CS could resolve the problem.
Then again if you are happy with the ipad, stick with it and save some money.

I have refreshed everything many times.  The iPad is fine but has limitations.   Thanks for the advise.

Perhaps in the future, downgrading will be available. What is suggested below is the best case scenario, refreshing the firmware.

I have reset both CrystaSky monitors I have had and still a no go. The CrystalSky works fine on my Inspire 2 and Mavic but is real bad on the Phantom 4 Pro.  I think it is a connection issue so I am going to remove the USB board on the back of the controller and barrow one from a friend and test that.  I will let you know.

Had a CS on order but NOW having second thoughts!

DJI...get your stuff together.

As you have stated that the connection is bad, always make sure your firmware is up to date. Check the USB cable. Also, review the monitor's manual as it talks about configuring for a Phantom 4 Pro. Perhaps it is not configured properly: http://dl.djicdn.com/downloads/C ... uide_v1.2_multi.pdf

Also, please be careful about removing anything. You don't want to do anything that may void the warranty aspect of the product.

with my Mavic and CS devices, I have tested 2 cable before find a cable without problem. Now it's perfect.
maybe a way for those who have some problems...

Cable is usually one of the more overlooked part involving monitors. Glad you found one that works.

It's not the cable.  I have tried 3 DJI CS mounts and 4 cables.  That is why I think it is the Output Module of the controller or the controller it self.  This is my second CrystalSky and my P4P+ was in for repair and I received a refurbished item.  I sent my P4P+ in for repair because the Plus controller never worked very well that is why I bought the standard controller.  The only thing that has not been replaced is the standard controller.  by the way when I got the refurbished p4p+  the UV filter was broken and still logged in to the prior owner.

Can I take the Output Module from the Plus controller and put it on the standard controller?

Thanks Mark

Did that 5 to 6 weeks ago about this issue.  If I need to buy  the standard controller again thats what I will do.  I am just installing a different output module to see if it works better.

Part of the fun of owning these products is the ability to do what you are doing. We just have to put out that gentle reminder of the warranty. Let us know how everything goes.

It works with a loaner from a friend.  How can I just buy a replacement Output Module.   I tried the HDMI upgraded Output Module DJI sells and I still had the same problem.  Will I have to go through support again?

I also received a defective unit after sending my drone in for repair.
It is unbelievable but sadly DJI has no incentive to change their manners since you keep buying their stuff.
As for me I have decided to postpone all purchases, there are just too many problems and no customer service to speak of.

Fortnight, sorry to have kept you waiting for the response from our engineers.
Since this issue never happens before, could you please try Android tablet to see if the problem persists, if so, maybe there are some problems with the RC or aircraft rather than CrystalSky.
If not, the RC, aircraft and CrystalSky all need to be sent in for analysis, please post the case number here when you get it. Thanks.

I know what is wrong.  I have a bad Output Module on the back of the standard controller. I took  one from a friends controller and it worked fine.  I also purchased a HDMI Output Module and it had the same problem.  Can I Just buy the Output Module that the standard controller has?

I am getting increasing frustrated with my crystalsky 2000nit. DJI go 4 keeps freezing on me mid flight and the picture just freezes follow by go app not responsing message. I just started the CS at home and it opened in a frozen state (see pic). Even when navigating through the CS generally things can be delayed or unresponsive such as a "back" button totally unresponsive until eventually it decides it will work. I'm totally losing confidence in this very expensive device. To have my P4pro in the air with a frozen CS is unaceptable. Ipad runs flawlessly compared to CS, very dissapointed indeed

Sorry for the unpleasant experience and the trouble caused, are you running the latest firmware and have you restored the device to factory default to have a try?
