Problema memorie Hyundai 21K95PF

Recommended Posts

La acest tv problema lui a fost memoria defecta 24C08 smd (procesor TDA9345PS/N3/3/1864),am montat un soclu ,am scris o alta memorie la care cand am pornit tv a trebuit sa-i fac reglaje pe geometrie ,tv ,functionand perfect.Daca il opresc de la telecomand s-au de la buton merge bine ,dar daca il lasa cateva ore oprit memoria revine la starea initiala cu geometria modificata si fara meniul de cautare, ca sa mearga trebuie sa-i fac iarsi modificarile.Care ar pute fi cauza de nu isi pastreaza memoria datele.

Cred ca sasiu E1 de beko e tvul.Incearca sa dai ok din telecomanda cand modifici datele in service sa vezi tot asa face?Ar fi ibteresant de vazut daca din service nu modifici nimic dar sa retii exact dimensiunile sa vezi daca si atunci se modifica ceva dupa ce sta cateva ore.

Tensiunea de 3,3v era de 3,2v am marit tensiunea de la 115 la 120v si tensiune de 3,3v a ramas stabila ,iar de atunci memoria i-si pastreaza modificarile facute in meniul servis .Intradevar iesirea din meniul servis se face cu tasta txt.Am ridicat tensiune la 120v deoarece tv are tub plat si la aceste tuburi am intilnit tensiune de 125v.Va multumesc tuturor pt ajutor
