Pictures attached. Service menu is shown as I was also looking at how many hours on the TV (862). Service menu was sometimes affected and sometimes not even while the main video was being affected.
Video is being fed by my Denon receiver via HDMI however the snow persists to a non-HDMI input as well (tested PC and an analog input with nothing attached).
I've read reports on the forums of similar issues on LG sets but hadn't seen other Panasonic owners complaining. Anyone else seen similar issues? Anything to try before calling Panasonic/service tech?
