I was thrilled when I saw a Reddit comment about this, and it actually worked with my Sony dumb TV + PS5 + Sony RM-VZ320 universal remote.

(I was sad at having to give up my nice PS4 universal remote, and not finding an equivalent for the PS5.)

However, I couldn't find a button on the remote that was the equivalent of pressing a PS5 controller's PS Button, and that's pretty important to the messy PS5 UI. But the TV had menus that could simulate pressing that button. So I upgraded to a Sony RM-VLZ620, which added programmable macro buttons, which I kludged hard to navigate the TV menus. From my notes:

  ### Programming PS Button

  1. SET(Hold 3 seconds, for LED, then keep holding)
  2. middle-circle
  3. (Release SET)
  4. System-Control-1
  5. 9, 8, 1
  6. Options
  7. Up
  8. Down, Down, Down, Down
  9. middle-circle, middle-circle
  10. SET

  Note: The **Up** is a timing NOP, since otherwise
  the TV usually only sees only 3 Down rather than 4.
