Hi Richard,
So now that you have performed the operations I described in the message /g/nanovna-users/message/20945, you have not forgotten to remove the BOOT0-VDD jumper and it will log in white the next time you turn it on.

What you wrote next, I don't understand:
In the message /g/nanovna-users/message/20957, he writes that he wanted to join VNA-QT and could not.
Why would you want to use a program made for another device for this NanoVNA-H ???
Each device starting with NanoVNA uses different firmware and the PC programs created for it do not match.
Here you may need a terminal program to check if your device is accessible via the COM port, even though you log in with a white screen.
Such a terminal program is Tera Term or PuTTY or if you know another one. If you don’t know, choose from the two above.
If you have a problem with the display, you just don't know that the foil connection between the display and the pcb has ever dropped and broken, so a white display is possible.
So telemedicine is difficult because there is always someone to tell His story to help, disrupting the successful error delineation.
So there we are, there is a chance that there is hardware damage if you still see a white screen and there is no information on the screen.
