Серва WK-4.3-1 медленно уползает в край (после падения ).
Вскрытие показало возможное КЗ .
Транзисторы в мосте Y1 , Y2 .
Возможен подобный дефект из-за полупробоя транзистора в ключе ?
Если есть архив с принципиальными схемами машинок ,буду очень признателен за ссылку .
При подаче питания , управлющий оставил в воздухе , происходит смещение на 5-10 градусов , очередная подача питания повторяет эффект .
С уважением .
При отключенном двигателе , напряжение на выводах 1\2 Uпит .
Переходы у транзисторов моста звонятся на сопротивление нормально .
Сделаю попытку в динамике осциллографом глянуть.
