I know these units get hot...looks like the heat is getting to the components and causing failure.  What is the latest on servicing time direct from DJI, as the Dealers don't have authority to send a replacment.

Did the backlight burn out ?

Likely, Now it won't come on... Went from normal Ultra Bright...to hardly being able to be seen.... to nothing..

It will make Button sounds...but no picture.  Going to check if HDMI Out works.

If your installed Crystalsky battery has a remaining charge and the screen won't come on at all or you can just barely see an image (possibly with a bright light shining on the powered-on screen), then the backlight has gone out.

I think it's over bar the shouting, the backlight is gone, circuit burn't out by overheating

Sir, we are sorry for the late response, may I know if you have contacted our support to send in the device for evaluation? If yes, may I have the case number please?

DJI Mindy: I was just going to purchase the 7.85 Ultra Bright in a few weeks.

In your HONEST opinion, are all of these issues reported in the forum going to be resolved with a future firmware update. Or, could the problems go even deeper with faulty hardware too?

This will certainly influence my purchase of a very expensive product.

Hold off on buying , the android version of DJI 4.2.6 and the CS is still on 4.1.18 about 5 versions in arrears. There has not been a firmware upgrade for 9 weeks

Also there is no support for the MA on the CS at the moment, so you can't use the MA with the CS.
I'd actually be recommending the Epson Moverio BT-300 glasses as a superior option to the CS.

Many people have been converted to the new technology

Rickyber, we have located the problem and will get it fixed in the next firmware.
Currently, when you encounter the overheat issue during flight, we recommend to land or return the drone, long pressing the power switch and then select reboot the device, the overheated error should disappear.
We apologize for the trouble caused, appreciate your patience for the next firmware.

I have the exact same problem. Brand new CS Ultra (less than 1 hour on) - second flight today we experienced a flicker and then boom, completely dark screen. All buttons work and audio feedback works. I can even still see the screen when I shine a light at it. But this thing is dead. I've contacted my dealer, waiting on a reply now.

As far as the burning smell, I experienced this prior to the first flight. Meaning, I thought I smelled something funny but it seems to have worked for 30 minutes after the smell happened before the backlight went out. Not sure if this is unrelated or not but my instinct says its not a coincidence.

Hi Mindy, I own a CS Ultra, can you please ask the engineers is the overheat message a "real" error message, that is the unit is actually overheating  and not a bug error message.

If it is a real error message, I would not like to keep resetting the CS to remove the message when in fact the something on the circuit board is about to burn out.

Could we also please get from the engineers what the maximum temperature the CS can operate in ? , that is the CS internal temperature, is it something like 60 centigrade ?

Thanks for your help

DJI Mindy: Wow!!!!
This seems like a major issue with the Crystal Sky beyond a firmware upgrade and is surely steering me away from purchasing one. I can't see myself purchasing one and then having it burn up, then sending it back for service at DJI which may be a lengthy process since it looks like you will be getting a lot of them back for service.
Can you please keep all of us updated as to the progress of the engineers working on this matter and if the firmware upgrade will indeed correct the problem.
I already own a Mavic Pro, Spark, and just got a pair of the DJI goggles this week, which I need to become proficient at. So, I was thinking of the Phantom 4 Pro Obsidian next and possibly the Crystal Sky.
Using my total common sense, the monitor purchase will be affected (when my tax refund arrives) as to how these problems are handled.

Ok so I managed to hold the power button down long enough to "reboot" the device. After restarting, theres a clear issue with the backlight. One half of the monitor is dim and the other is slightly brighter. Issue is, I have ZERO control when sliding the brightness slider.

This thing is defective and/or broken.

I've tested the Crystalsky Ultra with DJI Go 4.2.4 for 1.5 hours continously on full brightness and with the latest firmware for the AC, 3 full flights with the MPP and MA, ambient temp 23c and there wasn't a single glitch in the monitor, this was 4k 24fps, with caching back to the CS at 7gb

The hottest the Ultra panel got on max brightness was 41.5c , the side ports got to 38.6c and the back panel near the ports to 40c.

The CS fan never came on at all during the 1.5hrs and the temp was pretty consistent from about 15min from start up to the end. I'm not sure what the normal operating temperatures are for the CS Ultra, so the fan not comming on might be an issue, funny thing to note was the RC fan was humming away after 30mins and that has never come on before in longer flight sessions

DJI Go 4 4.2.4 worked flawlessly, there was no latency or pixelation at anytime in RC signal out or HD signal back, mind you I was using a Titan Cyclone 2.4ghz amplified panel.

I think they may have fixed the overheating problem for now, my CS build date it the 15/10/17 for reference, a couple of us who have this build date have CS Ultra's that get hot but have never failed.
Interesting to see how the other CS Ultra owners are fairing with the need firmware and 4.2.4

Mindy, I've been instructed to complete a repair form online. However, I want a replacement instead (as the product failed within 15 days). However, when I try to select replacement, DJI said I need to contact support which I have and they send me to the same link.

How can I request a replacement monitor asap? Thanks

I had the same problem...failed in 3 days...

My dealer asked me to send it back to them and I have. We will see how this all plays out. I have another unit with the same exact firmware so I am nervous to test it out.

I don't have a Crystalsky, so I can not test this idea...

Mount Crystalsky on an aluminum plate with a cut-out for battery.
Use thermal pad or tape between Crystalsky and aluminum plate to aid in heat transfer.  Allowing Crystalsky to be removed without a mess of thermal paste.

Around battery cut-out of plate, mount bars of aluminum cooling fins.  Use regular thermal paste between aluminum plate and aluminum cooling fins.

I have the same issue and even if replaced with a new unit... the warranty does not "reset". So DJI will not stand by a replacement new product for 12 months ...  Your original date of purchase remain in effect.  I have read on the forums of multiple returns... each time the warranty clock is running out.  I have given up on purchasing any further CS units  for the near future. Amazon reviews not inspiring. My Samsung Galaxy S8+ has great nits... but would prefer my CS Ultra to just work

I just bought my cs ultra hoping that it wound be better than ipad mini 4 but after 2nd flught it start to flicker, i hope i read this forum before I purchased one so expensive.

To me it seems like majority of the CS hardware issues are with the Ultra bright version... and mainly it's with the LCD back light... so I'm thinking that all of you CS UB users paid a few hundred $ extra for a standard CS HB with either a overdriven back light or just a brighter $4 back light which generates more heat that the units are not designed to handle.

That's a monstrosity mod that no one who paid a premium for a professional piece of gear should resort to...

I agree.  Unfortunately when you get stuck with a problematic device, and manufacture is not addressing problems, you are left with do nothing and getting nowhere or trying a few things in hops of making progress.
