Yeah, look at them real hard.
Or use a TEST meter as LOOKING will not tell you anything most of the time.

mains fail. check the fuse in the fuse spur. theres also a mains fuse in the panel may need checking. be careful as u need to isolate te power on the box to avoid electric shock. check all fuses
