BF548 EzKit Power_On_Self_Test Touchscreen LCD doesn't work

Using Visual DSP v5.0 Update 7. Have a BF548 EzKit v1.3. Set the board jumpers and switches as per the Readme.txt for the Power_On_Self_Test example. Removed the BF548_EZKIT_REV_1_4 symbol definition from the Project Options and did a Project, Rebuild Project.

 

Flashed the project into the EzKit.

 

Resetting the board w/o holding PB1 cycles the LEDs and the pictures cycle through on the LCD display.

 

If I hold PB1 and reset the board, then I can step through all of the tests UNTIL I get to the Touchscreen LCD test - five is shown on the LEDs, but the LCD remains blank white and nothing that I can do seems to make anything display on the LCD or make the test procede any further.

 

Any quick ideas for what I might be doing wrong ?

 

Thank you,
