buna ziua. Cum-necum am distrus telecomanda. Ce fac? Cine vinde asa ceva sau care ar fi codurile daca o telecomanda Pilot SUpertel e utilizata?Poate o telecomanda Hama sa faca treaba?

buna ziua. Pana rezolv beleaua cu telecomanda, a inceput alt necaz.Ponesc TV de la butoane (neavand telecomanda). Porneste 1-2 secunde, vad numarul de canal si prima imagine apoi dispare video si continui sa aud sunetul.

Probabil cade invertorul.Trebuie vazut exact ce si cum.

este un chassis beko,cu sursa z1j194-11 ? candva a-m avut si eu un asemenea lcd,aceeasi problema,la mine era sursa cu probleme,sursa de 24v care cade in timp,sapasem pe net se spunea pe situri rusesti ca buba e la neoane obosite,cu toate ca imaginea era ok ,nu pareau a fi neoane obosite,pe sursa este o rezistenta notata cu r903,1M ohm,se scoate si se inlocuieste cu una de 470k,zis si facut,tv ul a mers cateva minute bune dupa care iar a murit 24v,a-m schimbat condesatori, primar, secundar,circuitul ic900,traf choper 24v,diode duble de pe bara de 24v,dar fara rezultat 24v-era undeva la 16v,asa ca l-am pus deoparte,si in cateva saptamani mi-a cazut mocazie o sursa de la alt model ,a-m montat-o si totul era ok
