Bought Pana P50X30 (can't really remember the exact model number) back in 2011 when I was staying with my parents. TV is still there, working well, no burn-in. Only the remote spoilt few years ago. Bought a 3rd party replacement from shopee.

Bought Pana P50ST50 when I got married in 2013 but gave it to my in-law in 2016. TV is still there, working perfectly, no burn ins.

Love the deep blacks of plasma though
