am un monitor hpd2831a la care am unele probleme cand afiseaza osd-ul pe ecran apr niste dungi rosietice spre dreapta ca niste umbre sau albe intre acestea am schimbat aproape toate condensatoarele electrolitice si mai nou am probleme pe cadre cred deoarece imi afiseaza o imagine concava (est-vest) cand pornesc monitorul dupa o pauza mai lunga vede imaginea normala drepata cu niste margini negre dar apoi incepe sa se micsoreze devenind concava dar in acelasi timp variaza ca ma descreste ba creste iar

Pentru dungi cred ca este preamplificatorul video.La ew verifica lipituri...sau condensatori(nu cred sa fie condensatorii din cadre...)
