HP41cv buzzer problem
just to request of your help to try to understand why the buzzer does not work in my HP41CV halfnut (rounded display corners)
I opened it to repair the back screw holes area and desoldered the buzzer (from the extreme soldered to the calculator board), which is glued to the back cover. When soldered back in place, there is no answer to beep order.
I changed the buzzer with another one taken from a board for answer.
It can be heard a continuous and very very very low buzz when the calculator is "on"

Thanks in advance and kind regards
