Having a similar problem, maybe its the same?
21 Accord Touring... have had a month... So far, everything working great. Last couple days, Infotainment Screen goes to dark, after exactly 1 minute. I typically have navigation on at the time.
Or if on the radio, screen still goes dark, the radio will still keep playing
If I hit the Home button, the screen stays dark (radio or navigation commands still can be heard ) , But If I select Back, the screen then will reappear, back to whatever was on at the time.
Then will go blank again, after exactly 1 minute. If Im continually selecting choices on the screen, if will stay on. Its only when nothing is being selected, for 1 minutes, that the screen goes dark.
On this model and year, the Developer Options do NOT show under Settings, unless you go in and through a few different selections, add it to the menu. May or may not be related, but soon after I added the Developer Options to the Settings, this started happening.
Since its exactly a 1 minute increment thing, some kind of timer that can be adjusted somewhere?
