Welcome to the Raymarine Forum Andy,

What model of ST290 display are your referring to. Should the ST290 display be a Graphic or Data, then please indicate whether these displays are properly displaying other data from the system. If so, then it is recommended that the speed transducer insert be removed and inspected to ensure that it is free of marine growth and that its paddle wheel rotates freely. If so, the speed transducer should be tested. Should no fault be found with the speed transducer, the it would appear that the speed transducer pod may have suffered a failure. ST290 / ST70 Depth, Speed, and Wind pods can no longer be serviced and have not been available for some time and have collectively been replaced with Raymarine's iTC-5 Analog Instrument Converter. The latter may be interfaced to a spur socket within the ST290 backbone via an A06048 / 15.7in (0.4m) SeaTalkng to SeaTalk2 Adapter Cable.
