Schema si dump Cinex TV 37511


Recommended Posts

Va salut, un coleg mi-a adus acest tv Cinex TV 37511, care nu porneste, desi toate tensiunile sunt in regula, nu am gasit (inca) nimic defect

Componente: Sursa TDA 16846, memorie 24c08,  BV - TDA 1771,  jungla si procesor STV2256H, ST92195C7B1/PFT

Daca se poate un dump si schema, va rog. Banuiesc ca ar fi un sasiu din familia PT90 dupa seriile de pe eticheta....pe sasiu nu scrie nicaieri modelul.

Mul?umesc, descarcasem deja un dump de pe Elektrotanya, dar era pentru un alt tip de memorie, de aceea am cerut si alta parere.

E posibil sa fie chiar procesorul defect, cand apas (Program +) ledul da sa se stinga, dar in acelasi timp tensiunea de 5V dispare,chiar daca scot memoria sau pun una ,,goala,,. Stabilizatorul LM317 fiind deja schimbat. Mai verific maine cu dump-urile astea...
