It's a gauge problem. TS says that the speedometer is still working and only the odometer and trip meter aren't moving. Since it's analog, it's very likely that it's a broken gear or another mechanical part inside the speedometer gauge.

DIY: The gauge can be taken apart and checked if the broken part(s) can still be repaired. If not, buying surplus is your next best option. Just make sure to copy the odometer reading from the old gauge to the new one.
