    Pot fi nenumarate cauze, greu de apreciat de la distanta, dar cel mai posibil este un element instabil, cu parametri ce au mare fluctuatie a valorilor in timpul operarii, din cauze de temperatura, material, caliate slaba, etc, posibil condensator, resistor, semiconductor instabil, etc. Piese de slaba calitate incorporate, greu de depistat de depanatori care nu au nici un interes sa piarda ore sau zile ca sa gaseasca un rezistor sau condensator de slaba calitate si care costa poate mai putin de 2 euro. Un amator pasionat te poate descurca cu solutii ieftine dar mult timp de cautare, slabe sperante de la depanatori sa scapi prea usor, vor cere placa intreaga sau modulul intreg sa fie schimbat si asta costa.
