    Hi Betty,

    You need to follow the 947 init sequence on datasheet first and then init 948.

    The 948 should also be powered up after a compatible Serializer has started sending valid video data. If this condition is not satisfied, then a digital (software) reset or hard reset (toggling PDB pin) is required after receiving the input data. 

    Best Regards,
