67exec Posted November 11, 2019 Report Share Posted November 11, 2019 (edited) So a couple years ago I swapped a dna 60 into a Hana v4. I got about 10k hit count and it started cutting out and making weird buzzing sound when firing. I stuck it in a drawer and ran my silo 75c. Fast forward to Saturday and my silo either got lost or stolen while we were in town getting groceries. I'll try posting a short video of device monitor while firing. I resoldered the power in and out connections, tried 3 different batteries that work well in other devices. I haven't Vaped over 45 watts for years, usually 37-40. Edited November 11, 2019 by 67exec Just did a couple screenshots from the video Link to comment Share on other sites More sharing options...

67exec Posted November 12, 2019 Author Report Share Posted November 12, 2019 I've been messing around with my dvom, it has min-max capture. I'm starting to suspect the board. When device manager is showing input voltage is dropping to 3.11v, the dvom shows 3.744v at the opposite side of the solder holes as the wires are soldered. I used to have either an extra 40 or 60 in a box of stuff somewhere, I'm going to try and find it and see if it works better. Link to comment Share on other sites More sharing options...
dwcraig1 Posted November 12, 2019 Report Share Posted November 12, 2019 Have you measured the voltage with a meter on the side with the wire? Link to comment Share on other sites More sharing options...
67exec Posted November 12, 2019 Author Report Share Posted November 12, 2019 That was my 1st test with the meter, I just figured it more relevant that the the connection between the wire and the solder holes was good. All power wires are 18g silicone wire. When I get home tonight, I'll take a some pics of the wiring. Link to comment Share on other sites More sharing options...
dwcraig1 Posted November 13, 2019 Report Share Posted November 13, 2019 When firing via Device Monitor in EScribe do you get the same results? Link to comment Share on other sites More sharing options...
67exec Posted November 13, 2019 Author Report Share Posted November 13, 2019 SeeYes, I do. Also here are 2 pics from last night, I got busy and didn't get a chance to post Link to comment Share on other sites More sharing options...
dwcraig1 Posted November 13, 2019 Report Share Posted November 13, 2019 What I was concerned about is if the power wire's solder joints are connecting to the other side. If the voltage when firing is the same on both sides then they must be. Link to comment Share on other sites More sharing options...
67exec Posted November 13, 2019 Author Report Share Posted November 13, 2019 I found a 60 out of a plastic mod that got broken that still works. I'm going to swap it, and see what I get. 1 Link to comment Share on other sites More sharing options...
dwcraig1 Posted November 13, 2019 Report Share Posted November 13, 2019 Let us know how it does. Link to comment Share on other sites More sharing options...
67exec Posted November 14, 2019 Author Report Share Posted November 14, 2019 It's definitely a bad board. Unfortunately I must have stressed the ribbon cable in the change over, as it doesn't work. The mod I took the board from was a small screen. Flashed to regular firmware before hooking up the large screen, but it still doesn't work. The mod fires correctly at 50w, which is higher than I vape. Also, unless the board totally resets to like brand new when you do the change from small to large, this mod was never used?????

dwcraig1 Posted November 14, 2019 Report Share Posted November 14, 2019 Yep, I tried it and it reset to zero, flashed it back and still zero. Link to comment Share on other sites More sharing options...
