My friend told me a ‘power surge’ could have fried it....IDK...maybe he’s right?
I've had a couple 2nd/3rd tier LCD TVs die within 2 years, and several LCD monitors lasted a bit longer.
I always attempt an autopsy and 80%+ of the time, they have failed capacitors. Back in the CFL backlighting days, a few had heat-stress, failed solder joints on the power board subcircuit for the CFL tube power.
Besides that, if it lasts more than a month but no bad caps, I usually assume a power surge.
Of all LCD TVs or monitors I've had, a Samsung 46" 1080p TV has the most running hours at around 10 years old, but also seems to have higher build quality, weighs a lot more than typical 50" sets sold today, yet barely even has any smart features for the $800 it cost at the time.
That influenced my choice to buy another Samsung a year ago, one of their lower end models for a different room, not to replace the 46". Knock on wood, I hope to get at least 4-5 years out of it. So far, very happy with it. I'm not a TV-spec nerd, am fine with the picture quality. Since I don't use the smart features much (aren't wanting to add apps), I'd rather have the Samsung Tyzen OS after my last Hisense set with Android was buggy for a long time... then eventually died at ~18mos. old. Definitely an android bug problem because once I stopped using it as a smart TV and disconnected internet access, the uptimes between crashes greatly increased. That !@#$ Hinsense would even crash when turned (soft-) OFF, needed wall plug pulled and fresh boot to work again. Newer firmware did not help.
