i still have my LG 32in since March 2007 bought for 60K.. and we've been very hard on it back in the day.
using its analog RF for TV viewing ever since, it went blank and white in late 2012. but its lone HDMI input using either a BD player or the xTreamer MK1 is still in very pristine condition. we had it checked by LG back then and they were even surprised of its condition why only the RF input is black & white while the rest has PQ still like new.
anyway, I had it installed on our spare bedroom after buying a new 3D Smart 42in LED LG on Jan2013. the 32in LG LCD only being used very very seldom nowadays just for movie viewing. at 9years, it's PQ via HDMI is still very very good... no issue encountered at all even its sound, buttons, everything okay except for the back&white on TV mode.
BTW, we've only plug it in generic brand surge suppressor...
