itaste vv repair (photos added)

SWMBO's itaste has developed fire button problems and the display is showing an open circuit=no atty, so it's time to have this baby apart and see what's going on.
As there isn't much on the net about taking one of these apart, I thought I'd just go for it and see what happened.

1st mistake, don't bother trying to get the five top rivets out, I centre punched mine ready for drilling before I realised that it's only the bottom single rivet that needs to be removed. The whole inner assembly slides out once the bottom rivet is free, the only thing holding the guts in at this point is the hot wire to the centre pin.

I've established the problem, it's a dodgy negative connection, a relatively easy fix.



This is the innards removed from the casing.



A photo of the board containing the firing button, it slides into a groove in the top cap. The problem is circled, that blob of solder is the negative connection. It relies on contact alone to make the circuit as the top cap can't be soldered to, it's not a great design TBH.




My fix was to solder a wire to the solder pad above the circle, (the real negative connection), and fold it up around the top cap, this traps it between the cap and the casing.


I made a new case from an old towel rail! (should have wiped the fingerprints off first!) The original got really scratched up from getting the rivets out, it was a bit of a mess in the end.




The finished item, it works properly now. I glued the top cap and bottom section with epoxy, I didn't fancy trying to rivet the thing back together.

I'm impressed, speaking as one who has the manual dexterity of a newt!
