My mother-in-law is coming to stay with us for the winter (her dear husband passed recently). We are turning our living room into her "apartment" because it is at the other end of the house, and will give her some privacy, if she wants it. Currently, she leaves her TV on all day and night, because she has trouble sleeping. Hers is an old heavy, deep style, and too hard to move, so we are going to buy a new one for her room, but we have heard that the newer TV's cannot be left on all day and night. One salesman told us that the average LCD is designed to be used for five or six hours a day maximum, in order for it to last about five years. If Mom leaves it on all day, it will only last a year, at best. Is this true? Are LED TVs the same? Are there any sets out there that I can buy that Mom can leave on? I want her to be as comfortable as possible under the circumstances, and if the constant noise of the TV helps her, then so be it. Please help! I want everything ready when she comes in two weeks.
The lifespan of an LCD television depends on the life of its backlighting bulb. These bulbs are often rated to above 60,000 hours in regular fluorescent-lit LCD panels, whereas new LED-backlit televisions have expected lifespan of over 100,000 hours.............
So do the math and you'll figure out how long your LCD or LED TV will last if left on 24/7.........
And that's MY opinion, what's yours???
Thank you! That makes more sense! I couldn't imagine spending $700 to $1000, to have the TV last only a year. I wonder why stores don't educate their salesmen, so that they can educate us? But as long as we have people on this forum willing to help, we'll manage! Thanks again!
The only issue that might cause trouble would be overheating. You'll want to be sure to keep the air vents on the back of the HDTV open and leave the TV where air can flow freely around it. They don't get terribly hot, but without some cool-down time from time to time the heat could build up to a level where it could compromise the functioning of the set.
Fly! Eagles! Fly!
Thanks. We planned on putting it on a cabinet (no hutch, just storage under) not mounted on the wall. So we can leave about 6-8 inches of space behind it. Will that be sufficient? And should the cool-down time be daily? A couple of times a day? Once a week? I know I sound dumb, but the information on newer TVs only pushes their great picture quality, etc. No one ever addresses the mundane stuff, but I don't want to ruin the set because of something I should have known. Thanks!
My mother also leaves her TV on all the time. I think 8" would be sufficient for air circulation.
The only thing I have noticed, is that with her LCD is that when she tends to leave it on a particular channel for hours...the logos from that channel will get "burned" into the screen (it is noticeable when she changes channels). I do not think that would happen with an LED, but I am not sure...
Perhaps a white noise machine would help.
If you have a new set, of course you can leave it on 24/7. I might suggest you put in on a timer though for auto shutoff - even insomniacs could have the TV off from 4 to 7 am. or so LOL.
Smurfette- When you say that the logos get "burned in" is that permanent? Or does it fade after changing channels? I'm afraid that Mom probably leaves it on one channel for long stretches. She doesn't really watch it that much, except in the evening. I think she uses it mostly to have another voice in the room, to ease her loneliness. But maybe after she gets used to staying here, she won't need it so much. There's always something going on in our house!
The DLP, and I think LCD technologies DO NOT HAVE BURN IN. Plasma was the culprit with most TV sets that had burn-in. I've heard it said that the newer models do not burn-in, but I've also read "reviews" from owners of the newer Plasma TV sets that say theirs has burn-in, so I really do not know.
We have 1 LCD and 2 DLP TV sets(1 of which is a front projector), and I can tell you with 100 percent accuracy that a DLP DOES NOT suffer any burn-in not matter how many logos are on at the same time, and for any loooong length of time. It is impossible with DLP technology.

LCD's aren't as prone to burn-in as older plasmas, but it's still at least a potential issue with them. To quote the manual from my new Samsung LCD: "Do not watch in 4:3 format for a long time, traces of borders displayed on the left, right and center of the screen may cause image retention(screen burn) which are not covered by the warranty."
I didn't think it was an issue at all and who knows what qualifies as a "long time," but apparently there is some potential for image retention from LCD's including the newer models. I haven't noticed any issue with mine and I tend to watch a fair amount of programming in the older 4:3 format but I've only had it three months. If you kept it on 24/7 on 4:3 programming you might be pushing your luck a tad.
Fly! Eagles! Fly!
I have no idea how long they'll last, but my Mother's has been running for 3 years on. I think it's a Samsung. I'd go for a LED too, they don't put out near the heat.
Cheese with that whine?
Thank you all so much!! "Picking your brains" has probably saved me from a costly mistake! I must admit that I was a bit intimidated by the choices when I went to the electronics department and saw row after row of TVs, and felt that the salesman was only interested in moving the "slow models" and not really trying to help me find what I needed. Now I have a much better idea of what to look for, thanks to all of you!
Thanks again to all! Mom has moved in, and so far, everything is great! We ended up getting her a Sharp Aquos 32". There were some that were a little cheaper, but this one had a terrific picture and a remote that seemed easy for her to use. And we have agreed on turning it off each morning, during breakfast. Thanks again!
