Prodigy P2 or P3 ???

I did a search, but did not find the info I was looking for. Over the years, since 1990, I have Tekonsha brake controllers. I started with the voyager, then to the prodigy once I moved to the 5th wheel. Never had any trouble out of them. When I upgraded my 3/4 ton truck, I used the onboard brake control and at first it worked well, then started having trouble. I replaced it with a prodigy P3. I sold that rig in 2014, and got out of camping for a couple of years. I am now back in with a small rig. I installed a prodigy P3 in the current truck. Yesterday while towing trailer to dealer for recall, I noticed the P3 display was not lit. I assume no brakes, but with a lite camper it was not and issue for a short drive. The fuse was not blown. The controller was warm. I looked online and it seems there have been quite a few issues with P3s dying. I think my first prodigy was a P2, and never had any issues with it. Any recommendations or experience similar to this with P3? P2 or P3? It appears they have the same functionality, but the P2 does not the fancy display of the P3. I will try for warranty replacement, but I am not sure if I saved the sales receipt, of course it is in the camper.
