Hi , it seems you are experimenting a light engine problem.Here's how your tv works: http://www.youtube.com/watch?v=ZLLHnQ4y-wo Basically there's 3 LCD chips that create the colors and image by blending together.When these chips start to melt you will get those blue spots, pixilation even vertical lines.You will need to replace the light engine replacing the bulb will not solve your issue. Have a blessed one!
Hi,that's an issue with the light engine.Basically there's 3 chips blue,green and red they create the image on the tv ,when they start to fail you'll get those spots all over, mostly in the corners.God bless you!
Unfortunately, this sounds like a problem with your TV's lamp. They are not cheap to fix. Search Ebay for a new lamp and get someone to install it for you. These Mitsubishis have a design flaw that make the lamps burn out quickly. One thing that will PREVENT this problem is making sure that the TV's vents are clean.
the problem is in the light path starting with the blue input polarizer then the blue lcd hopefully its just the input polarizer. worst case you will have to replace the LCD block witch is expensive to do. the polarizer ia a speacialy tinted glass designed to help with the LCD's temp.
As I'm sure you will notice that you rub your finger accross the lcd panel when it is on and you will see a blue trail as you cross the screen. I would simply try to wipe the spot with a soft dry cloth while the unit is on and see if that corrects the problem. If not I'm sorry to say that the lcd panel has been damaged.
