    I have several blue spots on my screen and the longer I watch TV the bigger they get

  • jaybird619 May 03, 2008

    Blue spots appearing along bottom of screen and seem to be "blue tinting" the picture above the spots.. sounds like the same problem with a light engine others are having. Second time this would have been replaced for the set.. any opinions or advice?

    About 6 months ago we started to notice a blue spot on the lower right corner of the screen. Then last night the lamp went out so we replaced it. Since putting in the new lamp the blue spot has taken over the entire screen. Please help me fix this problem. This TV is not even 3 years old and so far I am not impressed.

You have a defective light engine and you do not have to be under warranty for Hitachi to replace this part. We just went through this and here's what you need to do. Call Hitachi's customer relations department at 800-654-7013 and tell them that you have a defective light engine. They will act like they've never heard of this problem but they have. They will give you the names of some certified dealers in your area to call. Once a tech comes out and confirms that it's the light engine, call Hitachi back and they will send a brand new light engine to the dealer and Hitachi will cover the cost of the part (cost $1500).

Here is the deal, if you're under warranty, Hitachi will cover the part and the install. If you're not under warranty, all you pay is the install. Our install cost $400. Others on this site have paid $200. Do not let anyone tell you that you have to pay for the light engine part...you do not. Hitachi has not recalled this part but they are replacing it for free. Also, deal only with Hitachi customer realations number that I listed. Good Luck

Blue dot on screen really small but noticable if you know what your looking for wondering if its a problem with the projection or if its a quick fix


If it's a CRT projection TV, it could be a burned spot in the phosphor of the blue crt. If it is a burned spot, I don't beleive there's a fix.

The other stuff is probably the Engine as well. Before going any further, have them replace it again and see if the other problems show up. I am willing to bet they wont. These Engines are mostly refurbished units and if they originally had intermittent problems on the Digital Board that comes mounted on the Engine it would get passed on to you.
I would not wait before having it replaced and I would Call LG first to let them know you got a dud replacement Engine. Let me know how it comes out.

It seems to be a dead pixel, best thing would be to have it replaced from the Seller, else you can get it replaced with a new working lcd panel. This may be an expensive solution.Check whether you have a worldwide warranty from Canon, that will help you on saving costs.

I have a sony kf-42sx3oou, i have just had the lamp replaced, since replacing it a few blue spots appeared in the top right corner but today a yellow line has appeared on bottom left hand corner, could you...


This problem was probably there before, but you only noticed with the new "Brighter" bulb.

This TV will require replacement of the LCD Prism unit.

This Prism blocks and allows colors so that the 3 LCD images may be mixed to produce the final image you see on the screen. When this becomes damaged or defective, it leaks colors (light). This Color Leakage apears as spots on the screens.

Where you see the spots is where the specific spot on the prism that is leaking light, the specific color that is leaking also.

This parts cost alone is normally $500 to $1000 dollars but is usually replaced under warranty. If out of warranty, I suggest living with it or selling it if out of warranty. Turn down the Brightness and it will not be as noticeable. I am sure you only see this with bright images.....like white backgrounds and such

Good luck.....
