Orion P1415 MT

Recommended Posts

Buna ziua , acest televizor de 37 cu sasiu PT90J cu procesor ST92195C7B1/PFT a avut initial defect transformatorul de linii . Dupa schimbare televizorul functioneaza , reactioneaza la butoane - interesant doar P+ P- , la volum nu actioneaza , nu are OSD , din telecomanda mfy cod 43 si 589 nu reactioneaza nimic . Am verificat cu osciloscopul intra semnalul de la receptorul infrarosu in pinul 1 al procesorului , banuiesc dump alterat in memorie sau defect pe scl sda . Va rog sa-mi dati un dump bun pentru acest procesor , multumesc .

Mfy43 este pentru vestel dar power si unele functii tot ar trebui sa le faca

Multumesc pentru dump , l-am folosit dar nici o schimbare in manifestare . Am mai sapat si am gasit TP05 pe bara de 5 volti cu probleme , dupa schimbare s-a rezolvat  defectul , doar geometria din service a mai trebuit reglata .
