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!

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

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)
