These bulbs are very sensitive to contamination. When installing a bulb, do not touch it with your fingers, as this will leave your natural oils on it and that will become a hot spot and burn out the lamp.
Use a clean piece of toilet tissue when installing the new lamp to eliminate the above.
Good luck!

1,white spots appeared on screen,means the DMD is broken,you need a new DMD.
2,the projector running off after only a few minutes,means the Inductor (Sensing element),near the Color Wheel. Use a cotton swab moistened with alcohol to wipe the Inductor.

hi, you have a issue with something called a optical block, its basically where the image is colored, that piece needs to be replaced

Bad Light Engine. If still under warranty Get it Fix Now if not call UED for rebuilt one ,you can also CK on E-Bay in Parts Electronics. 1-800-648-6657 This part is not Cheap!

if it is a panasonic pt-50lc14 then you will need a new bulb. you can find them online, do a yahoo or nextag search for the ty-la 1000 bulb and you can find them for around $100...

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.....

it's the light polarizer on the blue lcd panel. it's fried due to excessive dust and heat. unfortunately you'll have to replace the optical engine.
