help identifying diode in a switch mode power supply board (for LED TV)

[electron_jj]

Hi everyone, I am new to this forum. I would like to seek help on identifying a tiny diode in a switch mode power supply board in a Panasonic LED TV. The diode (D407 on the circuit board) has been circled in yellow in the attached photo. I have also attached the portion of the schematic with D407 diode highlighted in green. Unfortunately, this schematic diagram which I have found on the web does not provide any details on the components. The diagram only shows the circuits with no values stated for the components.

I have desoldered the diode out of the circuit and measured it with DMM using diode mode and the voltage value is around 0.173 which I think it unusually low and may be defective. The reverse reads OL. The markings on the diode is IK4 6A. Many thanks for your help!

But 0.17 Vf is not "unusually low" for a Schottky diode, and as it reads open in the other direction I would definitely say it is not defective.

Great, thanks!
