Sounds like the display has aged and is failing.
It looks like there is a version of this clock still being made and sold but branded as La Crosse Technology:
La Crosse Technology WS-8418U-IT Atomic Digital Wall Clock with Moon Phase.

Question edited for clarity. Full 'make model (what it is)'.

Did you put batteries in both units and in the right order, sensor first?

Step 1: Insert 2 fresh AA, batteries into the TX29U-IT sensor according to the polarity marked in the battery compartment.

Step 2: Insert 2 fresh AAA, Alkaline batteries into the wireless thermometer according to the polarity markings. Step 3: After 5 minutes place sensor outside in a shaded location.
