    I recently acquired a 47″ Vizio that has a manufacture date in 2015. It doesn’t work. When I got it the standby light comes on but pressing the power button does nothing. I believe the power supply board is the problem but am not 100% sure. The power switch tests as good.

    During testing on the power supply, I attempted to jump a fuse and managed to short to a neighboring capacitor. I don’t think the capacitor was killed as it is a 470v capacitor and 120v are at the fuse. In the picture is the area of the PCB in question. the short was between the top capacitors top lead and the top of the fuse. I’m not sure what the component connected to that lead is(it’s the orange and black thing just above the capacitor) that then connects to a couple diodes and then into the 12v transformer). Since the short, the standby light hasn’t even lit.

    Trying to identify the orange and black component as I have no idea what it is or how to test it.

    An entirely new power supply is $80 and I don’t want to spend it as I’m not sure that’s the original problem.

    After half a day on google, I’m 95% sure the component in question is a double ferrite bead inductor.

    I like your way of thinking trying to get it to work and good luck, but there are some really nice deals on Good Friday for TV’s. I saw a 43″ Vizio for only $228
