Red spot on LCD

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?

    We own the Hitachi 50V500 and bought it about 3 years ago, while the TV was under warrenty the light engine was going bad ( had a red blob in the center of the LCD screen) so we got it fixed. About 4 months ago we started noticing a blue cloud at the top of the screen. This cloud has gotten bigger. I call and talked to a local technician, he said that it would cost $1800.00 to have it fix. Again the problem was the light engine. It would cost more than the TV is worth to get it fixed. I know that I will never buy a Hatachi again.

    I have a large red circle in the middle of my screen. It started off pretty small about a year ago and has slowly grown. It now covers nearly the entire space between the top and bottom of the screen. It is not terribly noticable on anything other than red. I can tell that some of the other colors are wrong, but it's not horrible. Anything that is red looks very blurry. Small red text is unreadable.

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.

Thanks for the posts. He saved $$$$.

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 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

A dark spot in the middle of the LCD display screen.

It can't be removed, unless its a dirt spot and then you can take a paper towel with some glass cleaner on it and then you can wipe off the screen.

Try that anyway and if it doesn't come off then you know the LCD is going bad on you and you'll have to get it replaced eventually.


Screen is dark, can see images in a sunny room.

I see this quite a lot. Sometimes it's a loose connections between the motherboard and the lcd display. Especially if the laptop is 3 or so years old. I'm assuming you did a hard reboot and got the same thing. A lot of time the backlight will give out on olfer laptops and the only thing you can do is replace the lcd display or hook it up to seperate monitor. Two things I can recommend are;
1. Plug the laptop into a crt or lcd external monitor and see if you get the same thing or if you actually get a good image.
2. Press [Function] [F4} and see if switching between exteranl and internal monitors makes a difference.

Red spot on LCD

1) That red spot means that a pixel is stuck, actually it's very common on LCDs.
2 and 3) It usually occurs for a manufacturing issue.
4) The most of the time it doesn't mean that the whole screen is going to fail, but in my case I would take advantage of the warranty if the laptop is brand new and the warranty is still there.
Good Luck!!!

This repair involes an eprom on the optic board. Hope the sheds new light........
