Hi All
it's my first post on this forum, any contribution is welcome
I got a valentine one, considered as hs, when I put the current it starts,
then after a few seconds it hangs with intermittent buzzer. (pic 1),
during the disassembly no screw so it has already been opened,
I do not know this material but I think something is missing at the places encircled with red (Pic 2,3).
If a person could tell me if I'm going in the right direction.
thank you in advance
