My TV clicks on, but does not click off, it has no picture & no sound... Upon my visual check there are no swelling of capacitors or dark spot on the board and all of the fuses checked out as good. When I did the voltage check the power board showed correct voltage as listed on the TV,  but the Zsus board was only showing 4 volts to the Ysus board when it should be 18 volts. After some time, i disconnected the Ysus board from the Zsus board and it still shows 4 volts at the connector when it should be 18 volts. My diagnosis is the Zsus board need to be replace or repaired, since I'm not a professional I thought I would ask others who might be able to lead me in the right direction.
