Greetings @Tom941,
Welcome to HP Forums and Thanks for the post.
I understand that you are not getting any display on your printer to select any options. All you get is a blank white screen.
Not to worry, I will be glad to help.
Have you tried any troubleshooting steps on your own?
Request you perform a hard reset on the printer as suggested in Step 4 of this HP Article.
If you are using any surge protector, please disconnect it and connect the printer directly to a wall outlet and check.
Let me know how it goes.
