I use to have Panasonic TC-P42X1 bought 2010 (I think). I replaced it last 2017 for a bigger model, I sent the unit to my parents. It broke around 2020 and the video board needs replacing (the one that controls the hdmi, component etc). Everything is all good (specially the panel) but we can't find parts. It is currently a paperweight in their place.
The reason I replaced it is for bigger size, electric bill and technology (not smart, vision, HDR etc).
The replacement is now broken just few months shy of 5 years. Currently have an OLED that I hope will last longer.
I really wish they can still make tvs as tough as plasmas, again specially the panel.
