I have a Tektronix TBS-1072B oscilloscope. I don't know how it got into this state, but it's in some sort of boot lock state, if that's the right term. I turn it on by pressing the power switch. Some buttons light up and the display shows up, I see the Tektronix name and logo, and an image pops up showing the model name. Then, the screen goes dark, and the process repeats again...and again. Essentially, it's stuck in some boot sequence on startup and it won't properly initialize. Does anyone know how to perhaps factory reset this oscilloscope? Or perhaps, any one know of a way to perhaps get some sort of start-up log from it as it boots up to see why it's like this (like through a serial port or something)?
