greetings, help with diagram, I have searched the web but it does not match the integrated jungle LA7674, I have problems with a resistance leads the position R591, connect the TV turns on alone, that is without pressing power, and that resistance is put on red lived, I changed it but it remains the same, on the screen a vertical line is observed, but I already checked the voltages of the ice veritical and it's ok, the + b is 112v, there is no audio either, my suspicion is focused on the jungle but I want Be sure before changing it, thanks.
