When the background on my laptop is dark, one can notice a tiny red spot on the screen. All I need to know is as follows:
1) Technically what's a red spot?
2) How does a red spot occure?
3) Is a red spot a manufacturing defect?
4) When there is a red spot on the LCD. Do we require the LCD to be replaced immidiately?
My friend's TV was well out of warranty and a Sears (the retailer) tech agreed that the engine needed replacement. They called Hitachi Customer Relations who will send the part to the home at no charge. Sears did not charge for the service call, but will charge $242 for labor to install the parts and adjust the TV.

Re: Red spot on LCD
We had the same problem and the infamous "red cloud" is a light engine defect and Hitachi knows about it. After calling Hitachis Customer Relations Department (not customer service) they referred us to a local Hitachi dealer that diagnosed the problem in less than a minute as a "light engine defect". We called Hitachi back and once they confirmed this with the dealer, they shipped the part to the dealer and the tech came out and installed it...looks like brand new TV. Here's the deal though, when you first call Hitachi, they will act like they've never heard of the problem until you have theTV looked at. They will pay for the part...$1500 but they will ask you to pay the install. Our install was $400...worth it to us on a $3600 TV. Be sure and call the Hitachi customer relations department and not regular customer service...you will get no where with them. The Customer Relations Department # is 800-654-7013. Good Luck!
We followed "varian's" advice and called Hitachi customer relations and scheduled a service appointment with Sears who was the retailer. The tech diagnosed the problem and waived the $105 service fee when Hitachi agreed to send the replacement parts for free. The installation charge will be $242 when the parts arrive. The TV was well out of warranty.
Our Hitachie 50" HCTD had a blue cloud and it is just over 2 years old. We were told by the company where we went to get it looked at that this is a very common problem and it would cost us $1,280 to fix on a $2,500 TV.
Quite a crock

Dead and Stuck Pixels
Pixel defects for an LCD monitor are defined as one of two types: dead or stuck. Technically, both types of pixel defects are stuck pixels but it really deals with the electrical currents and the state of each pixel or sub-pixel.
A dead pixel is defined as a pixel or set of sub-pixels that has failed and is permanently in the off position. This condition means that the pixel will not let any light through. This can be observed as a dark or black spot on a brightly colored or white background.
A stuck pixel is defined as a pixel or sub-pixel that has failed and is permanently in the on position. This can be either with a single or multiple sub-pixels for a given pixel and is best observed on a dark or black background. A white pixel means all three sub-pixels have failed while a green, red or blue pixel means one of the sub-pixels has failed.
Hope this helps, if so do rate the solution
Sounds to me like you have a dead pixel or one that has lost some of it's brightness. The smartest thing you can do is return it.
If you bought it from any retail store...take it directly to them...call the manufacturer and inquire about a faster turn around, be nice but FIRM...for example...you bought the item...then they should foot faster shipping time charges or in your case...since your not happy with it...you should get a brand new one.
If they balk at that...tell them you want a full refund. Keep going up the ladder with "let me talk to your boss/supervisor until you hear what you deserve to hear...and thats good customer service. That's playing hardball but after all you spent the money...you expect that what you buy is perfect until YOU mess it up. :-)
You have to weigh how much you spent on it, with how much you need it, combined with not being able to see it normally...against returning it and being without it. Play your cards right...the company should "make you happy".
Your light engine will need to be replaced as you have a LCD panel failure. Here is the link to the part number for the model 50V500 if you have the 50V500A it has a different part number. http://www.partstore.com/ProductDetail.aspx?ProductSKU=8286849&ProductType=PART&ModelID=374014
