Sziasztok!
Csak tanulságképpen:
Bejött hozzám a fent említett végfok.
Bekapcsolásra 1khz körüli tutulással válaszolt.
Elkezdtem méregetni, semmilyen hibás félvezetőt, szakadt ellenállást vagy zárlatos kondit nem találtam.
Rajzot, manuált nem találtam hozzá neten.
Végső elkeseredésemben a kisebb elkókat kezdtem szemügyre venni.
Ekkor jött a meglepi. A végfok panelen 5 darab elkó 0,47 mikró és 220mikró közötti apró elkók teljesen kapacitás vesztettek voltak!
Csere után első rúgásra indult!
Az eset azért is érdekes mert a készülék kb 10 éves lehet.
Gondoltam megírom, ha valaki ilyenbe belefut.
