Anyone know how to fix/technical info on LCD televisions?

[Minnie824]

Ok, 2 whole long weeks ago, we got a new television, and already have a problem with it. Its an LCD screen television and one little pixel is blue all the time. They're going to send someone to evaluate the problem next week, but before they tell me it can't be fixed, or its normal, I wanted to get some information.

We've tried to unplug the tv overnight to reset stuff, but its still there. One person told me its 'warming up' (for 2 weeks!!) and will eventually go away, but there has got to be some way to fix it right?

Anyone have any ideas, or know where I could get info on this? I want to be prepared before they come out. Thanks.

Due to current manufacturing methods of LCD display panels, a certain number of sub-pixel anomalies (a pixel stuck on or off) are acceptable. Because the manufacturing yield of perfect LCD Displays are very low, displays may have some sub-pixels that are either always on or always off. The cost of accepting only perfect displays could nearly double the price of a and LCD Display. This is true of all products using LCD technology, not specific to one manufacturer. If the industry attempted to set a zero standard, the current manufacturing yield would be so low that the cost of an LCD display would be many times higher than it is today. Luckily, most customers and applications are tolerant of a low level of non-performing pixels and prefer the lower cost that the existing standards allow.

Although this is for LCD panels, I would assume it would be the same for Televisions. It doesn't sound like there's anything they can do except replace it. If they won't replace it straight out (which it doesn't sound like they are doing), I would consider just returning it under the store's return policy and just buy another one.

That's the only thing wrong with LCD's some come from the factory with bad pixel's it's the nature of them..


It's not rare for them to have one pixel out of whack... my 20" lcd monitor at home had a bad white pixel.
