Head upstream to check the PIA..
"For the lamp matrix columns, transistors Q56 to Q63 are 2N6427 transistors which drive the TIP42 column transistors. Sometimes these can fail too. Before the 2N6427 transistors are two 7408 TTL chips at 9F and 10F which drive the whole circuit. These all connect to the 6821 PIA at 11D. Any of these components could fail too."
