How do I fix this 128?

I’m looking to sell my old device and upgrade to a newer model. But I want to make sure that it leaves me in the best possible quality. How can I fix this row ? The lights turn in but button presses don’t register. Please help. I may keep it if I can fix it. But it’s been bugging me for a couple weeks. Preformatted text.

that has a blown hc165 chip. SMD but easy to replace. e-mail info@monome.org and we can get it sorted-- take it apart and send a photo of the PCB
