The Room fuse powers all gauges except for the speedometer so check that fuses condition.

The cover to the fuse box explains where each fuse goes. Did you lose the cover? There is a pic in the FAQ section for the S4, but the S5 is very similar and the S5 service manual also has a diagram.

you could also use a test light and manually check all fuses takes about 2 mins tops.
