Hi,
Please try with I2C speed as 400KHz and sub-address size as 16 bits/2 Bytes in the Tuner connection set-up GUI.
Please check if I2C lines are connected properly. There should be 330 ohms in series with I2C lines and 4.7 kilo ohms(in general) pull-up resistances to I2C lines.
Check if the I2C pins are selected accordingly in PSoC Creator project. Check if baud rate matches with component and tuner.
Please ensure that power supply is selected as external and connect the VDD and ground lines of the board to Miniprog.
Thanks
Ganesh
