Many times when the "backlight burns out" on a computer monitor it is not the backlight at
all, but rather the switching supply for the backlight that's failed. I've fixed a couple
of these.

That would depend if the backlight is LED or cold cathode. I service equipment with
LCD displays with both types of backlights and burnout is very very rare. on small
screens like the P3 the light is not being pushed hard and should last a long long time.
As for burn in. One of our machines with a 14 inch LCD display does in fact burn
in. It takes a many months of displaying the same image 24/7. The customer never
sees the burn as that part of the screen never changes. but with the different screens
I use in diagnostics I can see it. If I leave it on a full white screen over night
it disapears and doesnt seem to come back for another several months so the burn in
seems to not be permanent. on the P3 I doubt this will ever be an issue.

No. The only possible issue is backlight failure, just like your computer or
TV screen.
Tnx, Ron, just what I was hoping to hear.
I usually turn the radio on in the morning, and off in the evening, longer
periods only in a contest.
Should I be concerned about the backlight? I've only had two burn out, one
in a laptop (NEC) and one on a desktop monitor (Dell).
I would suppose that the entire display module would have to be replaced.
