multumesc pt interes.toate tensiunile sunt normale,am inlocuit si memoria cu una goala si la fel.nu apuca sa apara imagine.filamentul se aprinde pt o secunda doua si intra in protectie.o schema ceva mi-ar fi de ajutor.nu am mai intilnit tda11020h.incerc sa scot schema dar este umilitor de greu.nu stiu care sunt circuitele de protectie si ,pe deasupra,are si smd-uri de 1milimetru.

momentan nu-mi dau seama ce sasiu este acest VORTEX.

sigur este o chinezarie, insa pe un site rusesc se discuta despre TDA11020H1/N1F00

care ar echipa si sasiul BX1S de la SONY(nu stiu ruseste , dar cred ca despre asta se vorbeste)

uite adresa: ... =clnk&cd=2

sper sa-ti fie de folos informatia si sa faci o comparatie cu ce ai tu acolo.

schema sasiului BX1S se gaseste aici:
