@andyversluys not necessarily shorted. The PLK marking would make this a Seiko voltage detector. That would also explain what you referred to as a "one part reads like a diode"

Check the datasheet [document|31825]
Let us know what your exact board number is.

@andyversluys The component is reference designator PU9004
[image|3095619]
and it is a S-1000N25-I4T1U voltage detector. I only have the schematic for R1.4 but it should still have what you need [document|31829][document|31830]

I do not know if Acrobat Reader will zoom in far enough for you to read the BV. I use a different viewer and have to o to 2000% zoom to see the smallest components.
