plcockrell Posted July 28, 2015 Author Report Share Posted July 28, 2015 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? Link to comment Share on other sites More sharing options...
John Posted July 28, 2015 Report Share Posted July 28, 2015 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? Link to comment Share on other sites More sharing options...
plcockrell Posted July 28, 2015 Author Report Share Posted July 28, 2015 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.settings.ecig Link to comment Share on other sites More sharing options...
John Posted July 28, 2015 Report Share Posted July 28, 2015 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.

plcockrell Posted July 28, 2015 Author Report Share Posted July 28, 2015 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.

John Posted July 28, 2015 Report Share Posted July 28, 2015 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. Link to comment Share on other sites More sharing options...
plcockrell Posted July 28, 2015 Author Report Share Posted July 28, 2015 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? Link to comment Share on other sites More sharing options...

plcockrell Posted July 29, 2015 Author Report Share Posted July 29, 2015 Any other ideas on how to get this working? Is there a way to completely reprogram the board? Link to comment Share on other sites More sharing options...
GreyUp Posted July 29, 2015 Report Share Posted July 29, 2015 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.GreyUpDNA200.zip Link to comment Share on other sites More sharing options...
Schnell18t Posted July 29, 2015 Report Share Posted July 29, 2015 Im having the same issue with my Hana. The screen isnt really off though, its just really dim, and its only happening to me when i press the power button. I did all the things listed in this thread as well.

retird Posted July 29, 2015 Report Share Posted July 29, 2015 What % is the firing brightness set at in EScribe? Link to comment Share on other sites More sharing options...
plcockrell Posted July 29, 2015 Author Report Share Posted July 29, 2015 Mine is currently the default settings. I have tried setting it to 100%, 0%, and also to random numbers. Link to comment Share on other sites More sharing options...
retird Posted July 29, 2015 Report Share Posted July 29, 2015 Sorry plcockrell.... I should have included quote of Schnell18t.... was asking him/her about the setting since it is occurring while firing... Link to comment Share on other sites More sharing options...
plcockrell Posted July 29, 2015 Author Report Share Posted July 29, 2015 Np the more information that's posted the better chance of finding a solution! I have also tried different USB cables and different usb ports just as a precaution. None of it helped. Link to comment Share on other sites More sharing options...
John Posted July 29, 2015 Report Share Posted July 29, 2015 Any chance you could post/link a video of what it is doing? Link to comment Share on other sites More sharing options...
plcockrell Posted July 29, 2015 Author Report Share Posted July 29, 2015 Yes and I could also come up to Evolve's office. I am only an hour away.Filming whats going on now. Will edit this post when its uploaded.Edit: video is a couple post down... Link to comment Share on other sites More sharing options...
John Posted July 29, 2015 Report Share Posted July 29, 2015 Also, if you fire the mod from inside device monitor (Puff button, then select 2 seconds or whatever) does it dim out the same way, or is it just when you hit the physical fire button?

plcockrell Posted July 29, 2015 Author Report Share Posted July 29, 2015 I am in Youngstown so I'm an hour from both.if I go into the monitor and do a 2 second fire the screen doesn't come on at all just like when I use the fire button.Here is the link to the video. Give Google a min to process the video. https://drive.google.com/file/d/1UlAY9Yrz8U0iWSKa-5pSIucW1ZSb5UpoRg/view?usp=sharing I would just download the video... Idk how long it takes to process it. Its only 80 mb. Link to comment Share on other sites More sharing options...
John Posted July 29, 2015 Report Share Posted July 29, 2015 If you want to come by the Akron shop tomorrow or the next day, we'll get you straightened out. I work approximately 2pm to 4am, so you wouldn't put me out if you stop by after work or whichever. I haven't dissected one of the new Hanas yet to see how they are being built, but they are pretty closely based on our reference design, so they SHOULD work. There are nuances to it, though, so it would be interesting to see what's going on, and if you're here I can't hold your mod hostage for weeks.

John Posted July 29, 2015 Report Share Posted July 29, 2015 Well... We replaced plcockrell's board so we could diagnose the problem... It was in stealth mode. I guess that's a relief. How it got into stealth mode may well be a question for the ages, but I should have checked it first. We're going to add something to device monitor that tells you your mode and settings, so we can see what state the device is in in real time. That should at least prevent this issue.

John Posted July 29, 2015 Report Share Posted July 29, 2015 To clarify, there is a minor bug, but the bug is that on powerup if you are in stealth mode, it should display "stealth mode" after the startup screens so you know what it is doing. The 200 isn't doing that properly at the moment, but it will with the next firmware update. Link to comment Share on other sites More sharing options...
FTB Posted July 30, 2015 Report Share Posted July 30, 2015 Having a somewhat similar issue - received my v200 last night, seemed to be working fine but connected it to eScribe to get the latest firmware updates. Screen randomly went blank; thought it might have been in stealth mode, but turning stealth on/off seems to have no effect. Did a hard reboot, and the last thing I saw from the screen was the stealth mode prompt - no luck getting the screen to start up at all since, regardless of FW, brightness settings, etc. Link to comment Share on other sites More sharing options...
