There's some evidence of green corrosion on the right of the last photo, and a bit of grey fur in other places.

I also note that there ar lots of tantalum bead capacitors all over the board. In other devices they are a 'change on sight' component. Generally though they will be on the power supply rails, and they seem to be at the right voltages so may be something to worry about later.
