Vamo V3 will not fire

[Ken-o]

One of my Vamo V3 reads "Output RMS" will not fire removing battery will either help or it will then display"Vamo"
once it went to "mean"

What is going on?

Holding down left button does nothing.

Changing battery does not help

You don't give much info to go one.

What resistance are you trying to fire?
Is the insulator between the positive pin & the ground in the 510 connection still in place?
Have you overtightened the delivery device smashing the 510 insulator?
Battery charged?
What batteries are you using?
Checked their voltage with a dvom / multi meter?
Dropped it?
Got it wet?
Could be the chip is fried or went wonky.

i think your left button is stuck in the down/pressed position.

i think your pcb board is sort of turned/twisted to one side slightly causing the problem.
