New dna60 will not power on

[Slownihota]

So I have a billet box that had a bad chip in it. I purchased a new board and installed it per the data sheet. I cannot get the chip to power up. I have checked voltages across the +/- battery terminals at the board and they are good at 3.8v. Checked voltage at the switch and I get a switched 3.8v. the device will not fire the atomizer or power up the screen. Any idea what else I could check? Thanks

Have you tried using the fire button that's on the board?

[Slownihota]

Yes I have, I have also verified switched voltage at the on board switch.
