Hcigar VT75D reset problem, help needed.

[Edwin1967]

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.

[Edwin1967]

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

[Edwin1967]

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.

This is what it looks like in Escribe:

The openings in the curve show when it misfires and resets.

If it's not a battery problem, or a connection issue, I'd suggest you open a Help Desk ticket for an RMA. Link below

[Edwin1967]

Thank you for the link, I posted the problem there and I hope they can help me.

[Edwin1967]

Still not resolved, any more ideas?

[Wayneo]

Well, what did the Help Desk say 15 months ago?

[Edwin1967]

They could't determine what caused the failure, and didn't answer my final questions, so I left it with that.

Now I tried the mod again after a long time, but still the same problem.

[Wayneo]

I guess you could start with a full screenshot and post it here.
In Device Monitor
View - set time scale to 60
Enable/click volts
Wait a minute then do the screenshot.

Do you remember having any leaks, or was this the behavior from new?
Does it happen with all atty's?

Thanks for sharing, but this is the Vt75D, so with 2 18650 batteries.

I will try to create the device monitor screenshot in the weekend, hopefully someone will have an idea, for I love the size format of this mod.

Take a really good look at the battery door, make sure it closes tight enough against the cells.
