I have a CTC169PGA chassis that died suddenly. I replaced the chopper transistor (Q4101) and regulator IC (U4101). When in standby, I am getting 14-15 volts on CR4118 but nothing on CR4116 (B+). Does this mean the supply is working and there is a short on this line (HV splitter maybe or CR4116 bad)? Or could this still be a power supply issue?
