When I indulged in my OLED in 2016, I told myself I would not go cheap for one time in my life, but if this thing dies before I'm actually ready for a new TV, my next ones from here on out will be budget TVs.
I've been reading your journey with great interest, and I admire your loyalty to your plasma. I have to say it doesn't sound optimistic, but I'll continue to cross my fingers for you.
BTW, I went from a plasma to an OLED and found the experience very pleasurable.
