  1. Hi all, until yesterday evening i was quite happy with my DNA200. When i went to bed i connected an usb charger for loading it overnight as every night since more than a year. This morning i woke up and noticed it didn't work. I opened it to have a look and noticed a weird smell. So i took out the battery and this is the state the board was in. Any idea what might have caused that (Box is 3dprinted, so chances of a short are low...)? Going to buy a new DNA200, but i definitely dont want this to happen that again....
  2. The ticket is already closed with a request to send the board back for further inspection. Might take a while since i live in Germany... I ran the test with a power of 60 watts.
  3. Well, the design of the function is well thought through i believe. It didn't fire the chip countinously, but fired for a certain time (not sure how long it was) with the configured 60w, waited until the voltage of the battery got steady again, fired again and so on, plenty of time to cool down i'd think. I think that i might have the same problem that these other threads are about (Chip suddenly dead while vaping, getting really hot when connecting USB...) /topic/68312-topic/?do=findComment&comment=914351 /topic/68313-topic/?do=findComment&comment=914354 /topic/68203-topic/?do=findComment&comment=913319 Sadly in some cases a FW-Update seemed to work, in mine it didn't
  4. Already tried that. Nothing happens, only a great amount of heat developed from the marked chip (the chips where the coating partly melted away get hot too, but this chip seems to be the hottest): The Pc doesn't even recognise a new device beeing connected.
  5. Hi, after succesfully building annother Mod with a DNA 200 i tried to run the battery analyzer because i hoped to get better settings for my battery than from what's printed on the lipo. I built a HUGE coil , put the whole thing in front of a fan and let it fire with 60w by the battery analyzer. After draining roundabout half of the battery (it was after ca. 30 mins), Escribe suddenly hung and didn't do anything anymore. I restarted the software, but it couldn't connect to the mod. I tried all sort of things (updating the firmware just resulted in annother "not connected" message), but EScribe didn't recognize the mod anymore (other DNA200 chips work). The screen stays dark, whatever i do. The board gets really hot when i connect either USB or the Lipo, but nothing else happens. There were no problems at all while vaping normally before. Firmware used: Version from "2015-08-07 EScribe" What happened to the board, is there a way to revive it?
