Hello All,
one of my devices failed. So, I opened it and on the board near the chip that doesn't respond anymore the visual inspection shows something very strange - it's like one of the 4 pins of the crystal oscillator is completely corroded - check the attached picture I made.
Have you seen such thing - I mean what can cause such corrosion (the air where i live is very dry and I've never spilled anything on the board, the rest of the board is indeed in excellent condition - like it has just left the factory)? Does such oscillator can leak something to cause corrosion like on the picture?
Any advice how to proceed? I am not sure that's the fault, but it looks very suspicious and it's on the right place on the PCB, in the region where there is fault. I don't have such part to replace it otherwise I would already have done it.
thanks!
BTW, the part in question is "DMX-26S" - I am attaching PDF datasheet and picture of how it's supposed to look when it's new.
