I just received my Hana Modz DNA 200 today. I had been using it for about 3 hours when the screen went blank on me. The mod is still working normally but the screen is just blank. If I plug the device into my computer and then bring up the device monitor I can see it working. This happening completely randomly. I was using the mod, went to re-drip, and the screen just stopped working normally.

When I try to restore the default settings, the screen will come on with the Upload Settings text so I know the screen is working. It will also come on with the Evolve DNA 200 logo when you reboot the device and when I tried to flash the firmware again. The only other time I can see the screen is when the device is locked it will flash the device locked screen quickly if I hit the power button.

I have also tried putting the device into stealth mode and then turning it off. No luck.

I have not been able to find anything else on this issue and I hope it is just firmware glitch. I am loving this chip to much to have to send it back already!

Below is the device monitor screen shot.

Edit: Also if I press capture screen it comes up blank as well. Which is making me think this could be a firmware issue?

Can you save your settings file in Escribe and post it here? If it shows the screen when you are uploading settings, then it sounds like some unfortunate combination of settings. 

When you put it into stealth mode, did it show "stealth mode"? When you put it back did it show "normal mode"?

What firmware version are you running?

Here are my settings.

When I put it into stealth nothing shows up. Same when turning stealth mode off.

I flashed the 7-16 firmware that was included with Escribe. I also tried the 6-30 with the same issue. I could be flashing incorrectly, I am still new with this chip. Tools > Update Firmware > Selected the 7-16 file that is in the DNA 200 folder.

Nope, that's the way to flash it...

What happens if you click "Restore Defaults" on the General tab of Escribe. 

It'd be very easy to explain what you're getting if it never showed the screen, then it would be hardware (or a broken screen cable, or the screen pulled out of the connector) but if it is showing the upload settings screen properly, then it has to be settings.

When I restore defaults the screen saying uploading settings pops up then I see the Evolve DNA 200 then back to blank screen. When I press the fire button after a restore I see the new coil screen for not even a second. I press the + and then I can turn up the wattage and hear it fire but still no screen.

Just to try things, try setting your active, idle and charging brightness all to 100%

Also, you're running in profile 8 presently, correct? That was the only one that wasn't set to the default 8.5 watts in the settings file you posted.

Set all to 100%. Still not working.

Yes I was in profile 8. I changed to 4. Still not working.

Is there any other way to "factory" reset?

Any other ideas on how to get this working? Is there a way to completely reprogram the board?

I'm having the exact same issue with my DNA 200. Screen worked fine for a little while.

I changed the orientation of the screen through escribe. Not sure if related, but thought it was worth mentioning.

Wasn't long after that the screen started only display too briefly to read it, then it stopped displaying altogether.
