DNA20D HELP!! Not powering up

[ThaSnibbla]

Ok so im building a DNA20d box mod. So heres my issue. I recieved my DNA20 a few days ago. So today I got all my soldering equipment ready for use. I plan on using the on board buttons to cut down on internal wiring. I soldered my leads(battery/atty connection/charger) on the board. The soldering is perfectly done. I then decided to attach my EFEST 18490(fully charged) to the battery leads. I connected the battery + to +, - to -. I was very excited at this point . But as soon as i attached the negative terminal of the battery I was dumbfounded . Nothing happened. Screen did not light up. Pressing the fire button does nothing. pressing the +/- wattage buttons do nothing. I am so confused. Is the board dead? I did nothing with the board other than take it out of the box to solder the leads. I never once fiddled with it. I have a lot of experience with electronics and computers. I'm hoping someone here can give me their 2 cents.

Do you have a multimeter? if so, measure the battery voltage, you may have a dud.

Otherwise, contact Evolv and see what they have to say.

Battery is in good working order. I use it in my provari regularly. Guess ill have to contact evolv. It just seems strange because ive read so many great thing about it and havent seen anyone else have this problem.

It would be helpful if you post a close-up pic of your wiring with the DNA20D and batt.

Im on my way to the laboratory. Ill have some pictures up within the hour.

Alrighty! Got some pictures. They were taken with an iphone so they arent the best but they are clear enough to see whats going on.... or isnt

 

[retird]

You can solder on the atty connector and attach an atty/carto and see if it vapes.....if it vapes try to adjust the wattage up/down.....it could be that the screen not lighting is the only issue.....if that is the case then possibly a broken trace in the ribbon cable or maybe defective/cracked display.......just a few things here to help ya determine whats going on.....then contact evolv....

Thank you for the quick response. I was actually just about to try that out, i decided to wait for input from veteran modders. Will attach my test carto and see what happens. I have already contacted Evolv, now waiting for a reply. BTW it is 113 outside today so i guess its time to enjoy a cold one and try to not get frustrated.

The pics look good. The only other suggestion, other than doing as retird suggests to see if there is a problem with the display, is to double-check the soldered batt connection to make sure the solder has actually adhered to the + and - poles of the batt.

So i did as suggested by both mamu and retird. The carto fired as a usual mod would do. Meaning that the screen is definately faulty in one way or another. Hopefully Evolv will respond soon. Thank you for your expertise in this situation Mamu and Retird. And thanks for the motivation to finally make my own dna mod. I have been reading a lot about mods that both of you have made.
