Don't look at me. I bought one of the first 747i availables on release (March of '07) and, though a little too 'banded' for my taste now, it's still going strong. I'm not getting rid of mine until it croaks or puts out such a s***ty picture I don't even want to look at it. That's the reason I kept my 27" 2004 Sony Wega CRT when I got the Olevia back in '07. No sense to get rid of the last of the great tube TV's if you plan to watch lots of SD in one sitting (even though the 747i's Realta is more than up to the task of rendering good SD on an LCD screen) to help the 747i rest a little and last a few extra months/years. Having a CRT and HDTV on the same room helps me keep them both lasting longer than one of them would last on their own given the amount of watching (both in HD and SD) I do on a daily basis.
Realistically though, most HDTV's in the market today (including the 747i) didn't have poured into them the technology, know-how and/or production quality that went into the making of those old CRT beasts back in the day. Those things were made to last, but nowdays some of them are made to last only long-enough for a person to feel they got their money's worth but then get another one cheap. Sony LCD HDTV's are as susceptible to failure as the Olevia's (maybe a little bit less since Sony is a big-enough electronics giant to put some real coin into its manufacturing/assembly of goods in third-world countries) because, sadly, globalization and the pursuit of profits have contributed to electronic manufacturers settling for 'good enough' versus 'is this as good as we can possibly make it?' And that's how prices of HDTV have fallen as low as they have (quality has to come down on the manufacturing in order for us to be able to get below-$1,000 50" HDTV's from top-tier manufacturers reduced to develop budget models to compete with Vizio for the attention of the budget shopper. Which is weird because, even though it started life as a deluxe TV brand in '07, the Olevia 747i HDTV's only found success when they were liquidated by online retailers for as little as $1,200 (or lower) in 2008. Which Olevia achieved by lowering the quality of inner components of the 747i with cheaper material that, a couple of years later, is contributing to these models' early demise. Capitalism baby, gotta hate it but we can't because it's the worse form of life except for every other one (communism, facism, etc.) that's ever been attempted.
