good afternoon I have a problem with a TCL 21K8 slim TV that is driving me crazy, at first I thought it was the amp but replace it and nothing, then check that the mute output of the micro always remains in high voltave, also, when I turn on the equipment and food the ADD and when measuring the output impedance they give me both outputs short, but when turning off the AMP they return to normal values ... although in the AMP inputs I have the normal impedances both on and off ... any help would be very useful attached part of the power circuit that is where I think the problem is atte ALQUIMIA PD: attached Power circuit of the applicator with what I have measured. the R845 did not exist and there were two bridges already manufactured ... the equipment has never been touched (until now) circuito.bmp [2.25MB]
