Hi guys,
I am trying to identify this surface mounted component on 2 failed 4 number LED display boards. I have examined it under a microscope but cannot see any markings/symbols/text, though it is hard as most of the device is submerged in some sort of conformal coating. I can see tiny wires going from each pin inside the component to the center square and inside the center square there is like a kind of mesh (appears conductive). My thoughts is that it is this component that has failed due to the pins being exposed to the environment (as everything else seems to be either coated or looks fine) - observed in both display boards. Does this look familiar to anybody? Maybe some sort of optical sensor/transmitter?
Cheers,
Dion
