Why do people say LCD TVs are the worst kinds of TVs because of the back light & once the back light blows out?

Q. Then you will have to buy a brand new TV.

I have an Insignia 32 inch LCD HDTV(Advanced series) and I have a feeling the back light could blow out at any moment,I have had the TV since February 27th,2010

A. >Why do people say LCD TVs are the worst kinds of TVs

Because they say silly things.

>because of the back light & once the back light blows out?

Sometimes they fail that way. With a cheap brand like Insignia it probably wouldn't be worth fixing.

>I have a feeling the back light could blow out at any moment,

Unless there is evidence of impending failure (flickering, off color startup, dim) this is a psychological problem. You have no way of knowing if it will last one day or 5 years. No TV is going to last forever.

Best Buy makes a lot of money selling extended warranties to people who have trouble dealing with uncertainty. People who "self-insure" by not buying extended warranties save money on average, but this is little comfort to the unlucky ones who's TVs die right after the factory warranty expires.

So called LED TVs (they are actually LCD TVs with LED back lights) should be less susceptible to back light failure.

Best thing to do is to stop listening to BS artists, enjoy your TV, and start saving for a new TV. That way when your Insignia finally bites the big one, you can just go out and buy a "LED" TV and a warranty with cash.


whats the best flat screen tv out there?
Q. i have a philips LCD HDTV 1080 regular channels suck.and the color goes dark and bright sometimes on all the channels.my spending limit is 1100.and only a 47" and up.are plasmas good?i heard they get hot.whats the best tv to get?i want clear crisp sharp channels.any suggestions?

A. SD is 4:3 aspect ratio and 720x480 resolution
HD is 16:9 aspect ratio and 1280x720 or 1920x1080 resolution

So there is a discrepancy on 2 fronts. The resolution one being the more significant of the two. It means that if you play SD content to your HDTV, the HDTV is going to up-scale the SD to its native resolution. That process softens the image quite a bit. There is nothing you can do about it. This is just part of the reality of owning an HDTV in a world where SD is still broadcast. HDTV owners just get used to it, sooner or later; and they start gravitating towards more HD content.

Also, broadcast TV, even HD broadcasts, are heavily compressed. So while HD broadcast will look way better than an SD broadcast, it won't look quite as good as BluRay. BluRay just has way more data/information to work with to deliver you a better picture.

Plasma can deliver you some of the best picture quality in HDTVs at superior prices. This is because inherent to the technology is superior motion playback and superior image quality. So you're not having to pay for extra features.

LCDs need 120Hz or 240Hz refresh rates to deal with motion blur problems. LCDs need to offer your LED LCDs in order to improve blacks, contrasts, and colors (and compete with Plasma). But you, the consumer, have to pay for those features. And those features are basically just trying to make an LCD image match the quality of a Plasma. So why pay the extra amount?

Plasmas do run a bit hotter than LCDs. But we're not talking "if you touch it, it will burn you" hot. Its a few degrees. If a pet or child brushed up against it, it wouldn't hurt them in the slightest of ways. Its more of an LCD fanboy misconception than anything else.

If you do go Plasma, I highly recommend you look at Panasonic first and foremost. They are the leader in Plasmas right now. They have one of the strongest reliability reputations in the industry (if not the single strongest reputation). They deliver amazing quality at competitive prices.

As for specific suggestions,

PANASONIC TCP50U2 - 50" 1080p Plasma - $989 @ ABC Warehouse
PANASONIC TCP50S2 - 50" 1080p Plasma - $1169 @ ABC Warehouse
- the S series simply has a bit higher contrast rating than the U series, but otherwise are very similar quality sets

Panasonic VIERA S1 Series TC-P50S1 - 50" 1080p Plasma - $1,030 @ Amazon.com
Panasonic VIERA U1 Series TC-P50U1 - 50" 1080p Plasma - $962 @ Amazon.com
- the S1 and U1 vs S2 and U2 mean that these are the 2009 models and the "2" ones above at ABC Warehouse are the 2010 models. But if you're looking to save a few extra bucks, these are an option to consider

If you are really set on LCD though, for any reason, I would recommend either a Sony or Sharp series. Look for something that is 1080p and 120Hz (or 240Hz). I think you can find a 46" or 47" model with those specs and within your budget.

SONY KDL46EX500 46" 1080p 120Hz - $989 @ ABC Warehouse
Samsung LN46C630K1F 46" 1080p 120Hz - $990 @ Best Buy
Sony KDL46HX701 46" 1080p 240Hz - $1,440 @ Best Buy (I know above your budget, but is a really nice set/series from Sony, so incase you could increase your budget a bit I thought I'd throw it out there)

Oh but, please don't rely solely on my comments, or any one else's. Please do go into a store and bring your eyes into the equation. Stand back from the TVs the same distance you would be at home. Then take a long hard look at content being played on them. You can use spec sheets and opinions/reviews to help your narrow the selection, but at some point, your eyes need to become part of the decision. If you can't see a difference, go with the cheaper choice and save the $.
