Dna40 dead board ?

[OthatGuy]

Anyone know how to test a dna40? I've got it in a mod and it was working great and just stopped it's like it's not getting power to the board but I've checked all connections, ground etc. And they are all fine. I can't get the board to light up. Any help is appreciated.

If it will not boot up and it for sure has power going to it I dont know of anything you can do. I you disconnect and connect power nothing happens? Its probably dead if your sure you have power to it.

The ions are all confused. Your using a red boot on a black wire that definitely is the problem.

Bummer

there's always that one guy lol ..

You may have version one that needs the screen harness silicon'd.
It's probably fine here's breaktru's quote

Page 14, Errata was added later on when the problem was discovered.

The reports from users with the ribbon cable on the PCB was that the dna would freeze or lockup. Another problem was the display would dim or flash.
I have not seen a report of Check Atomizer due to the ribbon cable. Check your 510 connector.

Check Atomizer: The dna does not detect an atomizer, the atomizer has shorted out, or the atomizer resistance is incorrect for the power setting.

Check page 14 on the data sheet..

I had a bad fire button. I jumped the wired going from the fire button andbit fired up and started working fine. Replaced button and I'm all good. Thanks for the help!

Thats good and bad, but at least its just a button

Yup, not a big deal and it forced me to double check all my stuff, two wires n tossed a new button in ...all good, thanks for the help.
