It sounds as if your printer has gone bad. Try completely removing power from the unit and rebooting it. I doubt that will help, but it is worth a shot. Is it less than a year old? Check on a warranty if so.
You can do most operations from the Windows software. The screen is not needed. Please see the online manual about this: https://files.support.epson.com/docid/cpd4/cpd40876/index.html
Specifically, you do not need the screen to change an ink cartridge and you can check the status of your supplies through Windows.
This printer is listed at $80 retail and on sale for $60. That's probably cheaper than it costs to buy a set of ink cartridges. So, don't waste too much time on this unit. It's unfortunate, but ink jets are designed to fail. They are wasteful, have a finite life (due to dumping ink in the bottom of the printer), and are extremely expensive to operate - a money making racket for the manufacturers.
