Good day everyone, i have a sony home theater thats dead, totally no output voltages at all. Im not able to post the service manual here as it says size too big. So i attached a capture of the schematic and the photos here.
VCC missing on STRF6168. VCC on STRV153 is fluctuating from 12v to 15v. I have replaced D923 (10V), D924 (24V), D925 (5.1V) and D926 (10V). If i remove D923, the voltage is stable at 13v. Am i missing something here? Something is not right somewhere. I have measured multiple times all the components on the board both SMD and through hole components. All seems to be ok and working fine.
