Cu ce tensiune se alimenteaza inalta la acest sasiu si cum intru in meniu service daca nu am telecomana originala.?Poate gasesc si un dump probat.

Tensiunea de alimentare, UB, este de 105,5V la tuburile de 14 inch si de 115,5V la tuburile de 20-21 inch.

Service mode:

Se porneste tv in Power ON. Se opreste din telecomanda si apoi din butonul de retea. Se apasa de pe telecomanda tasta "text" (se tine apasata cateva secunde in plus dupa aparitia imaginii pana pe ecran apare meniul de service) si se porneste tv de la butonul de retea (Supliment nr.5 Depanatorul). Detalii despre modul service tot in revista Depanatorul nr.22. Spor la treaba!

Eu i-am gasit siguranta arsa.Am inlocuit-o si i-mi pulsa ledul si nu lua nici o comanda.Am scris un dump si acum porneste .I-mi zimteaza imaginea(mai mult pe fundal inchis) si tendinta de a umfla .Alimentarea este de 106v tubul fiind de 19inch,In manualul service alimentarea pt. tuburi mici este 125v iar la cele mari 140v.Nu mai stiu ce sa cred.
