I bought my P10 this last summer, and one morning recently the screen starting having a bright band that scrolls from the bottom to the top. It is pretty fast between 1/2 to 1 second for the bright band to move from bottom to top. The best way to describe it if someone tried to video record a old CRT monitor, it would show a scrolling line moving up or down.
I have changed the brightness to as dim as possible to make it less visible. It appears everything still work for outlets and the effectiveness of the P10 has not been harmed. I have tried a hard reset, but that did not seem to affect the issue.
The only other bit of information I can recall is earlier that week before the screen issue, there was a power bump (lost power for a few seconds in the middle of the night). I specifically remember this because there was not a thunderstorm/rain nor windy and was completely unexpected. Any helpful advice would help.
