Multumesc celor care au venit cu idei ,dumpul l-am scris pe o memorie noua,rezultatul acelasi. surpriza surprizelor,l-am asamblat sa il pun deoparte,dupa care la punerea sub tensiune imagine normala pt doua secunde,si iar patru imagini.Am inceput sa-l ciocanesc cu manerul de cauciuc al surubelnitei pe partea superioara al carcasei,gandindu-ma ca si asa nu am ce pierde(monitorul l-am primit defect),observand ca parca are tendinta de revenire.Intr-un sfarsit la o lovitura mai serioasa si-a revenit imaginea,iar acum functioneaza perfect cu tot meniul aferent. :ras:
