Am gasit un tranzitor defect - Q492 ( C114 )

Numai daca este SCURT complet toti cei trei pini puteti spune ca e ....defect sau masurat pe scala de kilo al multimetrului ...... INTRERUPT!!! Ala e un tranzistor PDTC114 care are incorporate in el doua rezistente de 10k!!! Deci? E defect sau...nu?!?!Ati specificat cand ati descchis topicul : nu se intampla nimic cand invart de ...potentiometru!! Acel ''potentiometru'' are ''limite'' stanga /dreapta sau se invarte ......incontinuu?!?! Banuiesc ca e vorba de reglaj digital si ar putea fi defect chiar acel ''potentiometru''
