I think LG televisions look very good, but I struggle with how often I hear complaints, both second-hand and first-had, of issues with their electronics. I feel rather strongly that if someone wants a LG TV to last them for 5 years, then they better have a 5 year warranty on the display.
This is not something I see or feel with Sony, Samsung, and Sharp displays. Even Vizio, from what I continue to read online, has a better track record for reliability than LG does. Mostly, it seems, due to under-performing capacitors and power supply boards, but also lines which go out in their displays.
I am hopeful with their $3,500 price tag on the OLED models that perhaps they offer a bit better overall build quality, but based on their track record, I am dubious.
It is nice that after half a decade of OLED promises that it looks like we may have some actual product coming to market, but I'm not thrilled about LG being the one to 'lead the pack'.
