Thanks for the quick reply.   I found a USB-A drive and it is formatted to FAT-32.  Its size is 4GB.  I copied the two files from the Zip drive again.  Went through the recovery procedure again.  Same results:  I hold the check and X while it’s powered on, the meter lights are on, the setup light is flashing, then after about 3M seconds the main screen flashes, there is a click, and it all goes dark.  The screen is dark but still slightly backlit .  Turning it off the screen goes completely dark.
