Re: Sony XBR75X850C no picture backlights on
There can be some secrets as i have seen on my Sony, you know, but it's possible also a failure in the ICs, it's very uncommon that searching for the panel model i don't find anything, searched also S650qf59 OR S550qf59 OR S500qf59 OR S470qf59 but nothing, so i re-ask you is the model number exact? With no datasheets is not possible to proceed i think, as all tcon i have seen started by 12v in, not by a command from mainboard.
