Hcigar VT75D reset problem, help needed.

Recommended Posts

I have a VT75D for some time now, but from the start it has a problem.

The 75C board resets itself spontaneously on an irregular basis.

When vaping it performs okay but sometimes after two vapes it resets and sometimes after 20 vapes.

I tried escribe several times to adjust settings, but doesn't help, I cleaned it which doesn't help also.

Eventually i opened up the modand made sure battery contacts are all good, still no solution, does anybody have an idea what to do?

I'm thinking that your saying that the batteries disconnect. I'd be looking at the small spring loaded contact that the battery door connects with when the door is closed. That Is what I'd be looking at first.

Thanks for the reply, but the contacts are cleaned with alcohol and the spring seems to work ok?

Also no arcing marks, just nice and shiny.

What do you mean by resets. (Mod stops mid puff and goes back to locked state, or what) And afterwards what needs to be done

Yes when you are just vaping, you notice it stopped firing, then you can see the screen is black, when you activate it again (5 clicks) it shows the startup screen and it works again, for a few puffs before it happens again.
