Many many Yellowish and Dim LCD TVs...

[SingSing]

We most likely are tried to pretend that we did not see those Yellowish and Dim LCD TVs and Monitors on store shelves and in our homes. LCD displays depend on Cold Cathode Fluorescent Lamps to light up the screen. These lamps age within two years after heavy usage.

There are online stores sell Cold Cathode Fluorescent Lamps replacemnt kits for laptops, but replacing large LCD TVs backlite is going to be chanllanging.

So, should buyers beware ?

Maybe replacing lamps in DLP TV is easier than replacing backlighting in LCD TV ?

Maybe CRT back projection TVs still has a viable customer base ?

I purchased a used 17" LCD monitor recently for a friend. It does have a distinctive yellow cast and somewhat uneven lighting of the screen. But it's over 6 years old, so not unexpected. It's used for office work, so I was able to change the color temp to a somewhat bluer shade and it works fine. The cost and time to replace the florescent tube wouldn't be worth it.

I see some LCD devices are now using LEDs for back light. That should cure the back light aging problem for future displays.

WTH kind of post is this? Sounds like a foreign poster that works in an assembly plant trying to make a native english speaker type of post. Reminds me of the posts I see on Yahoo movies sometimes... egads those are full of blatant nonsense.

To the issue in question, I've use my Dell2405 display what I would term "heavily" over the last 3+ years with no sense of any yellowing.

Perhaps we shouldn't expect our new TVs to last for decades, but such is life in the technology world.

The point is that once your LCD tv is out of warrentee you can pretty much forget about it. There is no way to change those tens of thousands of transitors.
