First off, are you getting the same pattern exactly, regardless of the program that is being run?
And, can you please describe a little more clearly what you are seeing? Q7 and Q23 are the names of two transistors, which control rows 7 and 23, respectively, starting with row 0 on the top. Is it these two rows that are showing the issue, or are you actually seeing a problem with two of the columns? Is the rest of the board lighting, or are these the only rows/columns that are showing any light?
