Elias traced the path on the physical board with his probe. The 17ips72 was notorious in the repair community. It was a 17-inch panel, but the interface was a nightmare of proprietary nonsense. If he guessed the voltage wrong on the input pins, the delicate thin-film transistors would pop like bubble wrap.
