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

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.
