One of my big-screens is a somewhat older “rear-projection” model — it has a single bright white light, that is used to drive the display. It fades over time, and will last maybe 15,000 hours. It is however replaceable — costs around $200 bucks, but cheaper I think if I shop around.
I’ve bought 3 replacements, so I always have one around, and I’m on my 3rd bulb, so I still have one left. I’d say it lasts about 2 years per bulb, so in another year I’ll probably buy another replacement bulb, and then ditch the TV when I run out because there is better technology coming.

Welcome NOOB
Your stay is highly speculative
Intersting, I have never seen anyone actually doing this. Good to know though. My LCD is getting close to the 4 (or is it 5) year mark and I sometimes feel it is getting dimmer as well.
I might as well check out what my lightbulb would cost me and get some DIY action going.
Insted of just ditching it, sell it on eBay. I’ve done that successfully with two rear projection CRT TVs.
me- 1994 Sony, 20" / 1999 Sharp 25" ... did not even bother to look at the new stuff over the years- until this past Christmas 2011-when i saw price$ drop to more normal rate of 500$ +- range. I am good to go for several more years until the new stuff drops some more. Really, the new stuff isn't that much better for the price/size selection .
My Toshiba went out about 7 years ago..the repairman came out..replaced maybe it was a “tube’ ha. Good to go.
and that TV got moved from Ohio to Fla, back to Ohio, back to Fl and then moved about 7 more times within FL...HA.
Ha. ha.
Wow, you have high standards. The new Freeper is making an anti-Romney post that's actually pretty amusing and is relevant to the thread. How long do new Freepers have to wait before this is acceptable?
More info needed.
Do own a gun?
Do watch network news?
ottbmare...your sign-up date is less than 5 years ago, so I believe that under rule VIII para 3, you are disallowed from questioning NOOB challenges by old-timers.
Also, I note the absence of an about page - I’m estimating a 40+% chance that you’re an Alinskyite plant.
Prepare to meet your ZOT!
(do I have to say just kidding?)
That was precisely the problem with my gorgeous 27 inch Sony Trinitron XBR. One thermistor failed in the 25 years I owned it and it cost only $100 to repair as good as new. I simply got tired of waiting for it to break last year and finally bought a 55 inch Panny. As we near retirement age, I'm hoping to get good life out of our two flat screens as it will become harder to replace them on a fixed "income" (if there is any income at all in this interest rate environment).
Hey, I resemble that!
What are you going to do? Tell on me for making fun of mittbots? Go ahead.
How long the screen display and backlights will last means nothing, if the weak power supplies that manufacturers are using is entered into the equation.
I’ve only had one LCD tv so far, and it didn’t last long.
It was an “LG” 26”, bought new in March 2009. Lasted until December 2011, when one day, it just went “poof” and the screen went dark.
Took it to a local repair shop and had them look at it. Bad power supply/voltage regulator. They kept it for a while, then told me the cost would be about $260 to repair including parts and labor. Not worth it, you can buy a new, larger tv for not much more now.
So we’re back to a 25+ year-old tube tv, looking around for a new model.
I’ve heard of numerous other flat-panel sets going bad due to power supply related problems. My suggestion to the manufacturers/designers would be twofold:
1. How about an EXTERNAL power supply (like found on small electrical devices, a “power block” of some sort)? It would remove a source of heat from inside the case, and, it would be easily replaceable in the event of failure. Couple this with...
2. A “power in” port on tv’s that retain an internal power supply. If the tv experienced a power supply failure, it would be a trivial fix to simply plug in an external source of power and get your tv back, at least temporarily.
The article concludes with the line, “In other words, don’t worry about lifespan.”
2+ years of life from an LCD tv is pitiful, and simply unacceptable.
You’re right! However did you figure out that I’m just a troll from DU? ;-)
And I KNOW no one ever believes it when a Freeper says this, but I was here long before my sign-up date. I got here in 1999 or early 2000, IIRC. But I changed my ID with JimRob’s permission for security reasons.

The voices tell me...;^)
