AntonioDNA250 Posted October 18, 2018 Report Share Posted October 18, 2018 I recently replaced the 250 DNA motherboard on LostVape Triade DNA 250. I respected all electrical connections. I installed a new display. The circuit does not turn on and the display remains black with batteries or a USB connection. The Escribe software detects the motherboard.

dwcraig1 Posted October 18, 2018 Report Share Posted October 18, 2018 What does EScribe show for your cell voltages? Link to comment Share on other sites More sharing options...
AntonioDNA250 Posted October 19, 2018 Author Report Share Posted October 19, 2018 Hello. Are you intending to read the escribe cell tensions? The display does not light even under USB. Link to comment Share on other sites More sharing options...
AntonioDNA250 Posted October 19, 2018 Author Report Share Posted October 19, 2018 I measured the solderings on the board where the battery cables arrive. Between Gnd and 1 I have a value of 4.20 volts. Between Gnd and 2 I have a value of 4.20 volts. Between Gnd and 3 I have a value of 4.20 volts. Between Gnd and B + I have a value of 12.6 volts. I attach the values of Escribe. I sent the original motherboard because she did not read the atomizer after 2 months of use .. Now this new motherboard replaced in warranty gives me this problem. All disassembled and assembled by an electronic engineer. I am disappointed by the Evolv. I paid the LostVape Triad DNA 250 € 200.00 a year and a half ago.

AntonioDNA250 Posted October 19, 2018 Author Report Share Posted October 19, 2018 The device remains on only if connected via USB and batteries inserted. Only with USB but without batteries the display does not light up but Escribe detects it. Only with batteries does not give any sign of life. If I hold down the fire button, the display will appear in sequence: check the battery, check the atomizer. Link to comment Share on other sites More sharing options...
Spector NS5 RD Posted October 22, 2018 Report Share Posted October 22, 2018 @AntonioDNA250 Are your settings in EScribe correct? Battery settings..... 3 Cell, Lithium Polymer, Watt Hour, Cell Soft Cutoff? How about posting some good resolution pictures of your soldering. The battery wires, The Balance tap soldering Link to comment Share on other sites More sharing options...
AntonioDNA250 Posted October 22, 2018 Author Report Share Posted October 22, 2018 Hello. Escribe is fine. I have also updated the firmware. The connection is the same as the original one. The cables in the box are original. I have already done the measurements and the tension arrives. Link to comment Share on other sites More sharing options...
AntonioDNA250 Posted October 23, 2018 Author Report Share Posted October 23, 2018 I measured the voltage between 1 and 2, between 2 and 3, between 1 and 3. Always 4.2 volts. Then I tried between Gnd and 1 = 4.2 volts, between Gnd and 2 = 8.4 volts, between gnd and 3 12.6 volts. Link to comment Share on other sites More sharing options...
Spector NS5 RD Posted October 28, 2018 Report Share Posted October 28, 2018 @AntonioDNA250 It looks as if you soldered the main positive and negative leads from the lipo ONLY to the balance tap area. You also need run the main positive and negative lipo leads to the back -board main B+ and B- pads........ Do you have jumpers, from the tap to the main batt input pads, your picture isn't showing? These 2 pads need to be connected to the battery >>>>>>>>>>>>> 1 Link to comment Share on other sites More sharing options...
AntonioDNA250 Posted November 2, 2018 Author Report Share Posted November 2, 2018 Yes thanks. The technician did not create the bridge between B and GND, between B + and 3. Now it works perfectly. 1 Link to comment Share on other sites More sharing options...
