attilaa0 Posted June 7, 2017 Share Posted June 7, 2017 Buna ziua!La acest tv am gasit circuitul de HDMI mux puscat.Nu am avut altul ,l-am scos de pe placa dar tv doar incearca sa porneasca de 3 ori apoi intra in avarie si ledul palpaie de 5 ori. Alimentarea e ok,banuiesc ceva pe placa de baza ,nu am gasit scurturi.Ori soft. Problema e ca nici neoanele nu se aprind pentru nici o secunda.Astept pareri!Va multumesc! Link to comment
Tavi Posted June 7, 2017 Share Posted June 7, 2017 (edited) e eroare de bootare a procesorului deci rutina de start e eronata poate ca verifica activitatea pe magistrale si cand vede ca nu e ok pe HDMI , blocheaza sau poate mai e ceva , o tensiune lipsa cauzata de circuitului defect Edited June 7, 2017 by Tavi Link to comment
stefank Posted June 7, 2017 Share Posted June 7, 2017 in manualul service : Error 5 (PNX85xx doesn’t boot). Indicates that the main processor was not able to read his bootscript. This error will point to a hardware problem around the PNX85xx (supplies not OK, PNX 8535 completely dead, I2C link between PNX and Stand-by Processor broken, etc...). When error 5 occurs it is also possible that I2C2 bus is blocked (NVM) Link to comment
