About LCD durability... just 50k hours for the backlights and the LCD panel is subject to aging, some are showing dead pixels or lines or a sort of cataract after a few years,

The high voltage inverters used to power the backlights are prone to failure and are virtually impossible to repair, you will need to get a new one,then you'll likely find out that you can't get a new inverter for your 5 yrs old LCD and you need to scrap the whole thing.

I don't think anyone coluld even dream about fixing a bad LCD signal board...

That's the digital revolution for you... it's all about crappy disposable miniaturized SMD cards, flimsy flat wires, junky chinese chipsets, brittle silver painted plastic cabinets and so on... nothing that fits in my home...

The "digital revolution"

While countries like the USA and Germany are still far behind their original schedules for full implementation of digital TV, the brazilian government, led by the drunk-in-charge Mister Lula da Silva seems to be in a very strange hurry to make Brazil jump quicly in the digital bandwagon. Digital transmissions will begin in December, but it seems that very few people will be able to receive the signals. The gang called "brazilian government" set a few years ago a completely irrealistic goal of having digital converters for sale for US$ 100.00 by the time of the beggining of the transmissions. Now it's clear that, at least on the beggining, those converters will not cost less than US$ 800.00 . The answer of the idiots that run this country is simple: the brazilian industry must be "punished" for it's "incompetence" , and the way to "punish" the industry is by massive imports of converters ... made in China.

I hate to have to say it about my own country, but, it seems that Charles De Gaulle once said: "Brazil is not a serious country" , and I have to agree. The government told us that the brazilian standard of digital TV was unique in the world, so how the hell the chinese have the know-how to produce millions of converters on that standard? I thought that this information was very well kept under secrecy by the government and the brazilian industry. If this were a serious country, a press and congressional investigation would be under way to find out how the chinese know something that only the brazilians and the japanese ( who helped us creating that standard ) were supposed to know.

Today the chinese will produce converters, tomorrow...they will produce TV sets on that standard, and that will be the end of the almost 70-year History of the brazilian electronic industry. We will disappear in the same way the american electronic industry disapeared - crushed by cheap, low quality Asian imports.

Welcome to the 21ist Century.

Hi Pete, I was not complaining about the price for the ATSC TV, just the fact that they advertise that all the Florida stores will have plenty of stock by the begining of June and you see that not one store in the South Florida area has one. I am going to keep the four sets I have until after the analog cutoff then get my one "free" converter from Comcast for the large Mitsu CRT rear projection that still has an excellent picture after 9 years with no service, no several hundred dollar replacement lamp, no color wheel motor, no "wobbulation" to make the micro-mirrors act like they are pointing in two places at once, no micro-mirrors, no cold cathode light tubes. When it dies then I will buy a "modern large scren. Yeah I am old fashioned and I like it! I know I am beating a dead format but when color came around it was backward compatible with monochrome
sets and I feel that should apply to digital and HD. BAH, HUMBUG.
Richard

I do NOT like empty cabinets (Why mister Harry Poster kills his TVs?)
Actually, your idea for the CTC19 is good; in my opinion my Irradio set ("Per tritwi") has an ideal cabinet for an "Apple" Philco TV set (or "proto Apple TV") from the 50s (except for 70 degrees deflection).
My Irradio TV will never be cannibalized until my death, of course.

Laptop computers usually have just one lamp, monitors and TVs usually have two.

LED backlights are used only in smaller LCD screens such as cellphones or digital cameras

Nonlosapeeeeeeeeevoooooooooo!
Thank you!
Do you like my recent posts in "Per tritwi", Francesco?
What TVs have you picked up with tritwi in Florence, as you wrote to me in your e-mail?

Yes, i enjoyed reading your posts, nice to know another Italian TV nut

Tritwi's TVs were a 26" 1976 Philco Magicolor w/delta CRT, a 23" 1963 Emerson tube B/W set and a 26" 1992 Philips "Match Line" W/built in subwoofer.

We will disappear in the same way the american electronic industry disapeared - crushed by cheap, low quality Asian imports.

Welcome to the 21ist Century.

I remember George Carlin said that the "two most common elements in the universe are hydrogen and stupidity." Stupid is as stupid does, stupidy is a common trait, it is not unique to the United States or Brazil. I still watch a "made in USA" TV set as my main one but it was made in 1982 by Zenith when it was still known as "Zenith Radio Corporation" at the Chicago plant. It's been our daily watcher since we bought it new in early 1983, just think, I'll be 41 on Sunday (July 8th) and I'm watching the same TV I did when I was 16 years old in high school.

I'm getting a little OT on this one, but it seems like Red China will dominate the world with consumer items and otherwise, they already dominate here in the US and it seems like they are going to do the same for Brazil. Along with stupidity, I thin politicians do have two chips in their minds, a stupidity chip and a "sellout to the highest bidder" chip. They don't really care if they serve the interests of Brazil, the U.S. or wherever they come from and should serve the people therof but they worship the "almighty Dollar" instead. It seems like your politicians need the same "wake up call" as ours do.

I have a cartoon somewhere that was made in 1953 on how the Red Chinese will dominate the US and later the world, it seems like it is coming true.

BTW, getting back to the subject, which standard will Brazil use, ATSC or some other standard? I'm not a big fan on how they are ramming HDTV down our throats but it would make a good opportunity for have a one world standard although from what I hear, Europe will be different from us. Looks like we got another "Tower of Babel" on our hands.

It's a hybrid system, half japanese and half local, a system specifically created for the peculiar characteristics of the brazilian TV market - a market in which the vast majority still don't have cable or other types of subscription-TV and on which the very complicated topography of the country makes TV transmission tricky. They say this system will allow for a greater number of TV channels and for mobile reception. I am no expert on digital TV, so I will have to wait for the beggining of the transmissions ( in my part of the country it will only happen in 2009 ) to see if it is really the wonder they are trying to convince us. What really irritates me is the sellout behavior of the politicians toward the chinese interests.

Hi horseman!
Actually, in my opinion, LCDs are good devices for computers, but LCD in my Compaq Presario laptop from 2004 is not so bright than a new one...

But...
Is there an high voltage device in it?
There are only some LEDs, i think.
