I have a yellow bar on the bottom of the screen with a splotch of white.


Try taking it in to be fixed if you have a warranty, otherwise, you might need to buy a new tv.

We have a Hitachi 50vf820 LCD television. We have changed the lamp several times since purchase. The picture is dull and not as sharp as it was new. We also have blue/purple splotches around the...


you can fix the dimmed look to the tv by purchasing a new ballast for the DLP bulb.

The spots are non-repairable as they are in the light engine assembly and those are nearly $500-$600 and very labor intense to install.

Hope this helps. Click the hyperlink above to buy the ballast.

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.....

Picture fine for 10min.-then flickers(clicking sound)& then colors gone yellow


Looks like it's a color wheel problem-found a cleaning walkthru online, but it doesn't get rid of the loud hum form the CW motor. Also, it is thermal related-when the colors went out I placed a fan next to the color wheel and everything went back to normal. Several design flaws here and for $3000 these companies should do better-severe problems after a couple years is not acceptable.

Mitsubishi WD-73827 with degrading color


Good Day;

More then likely your 2005 MODEL has a bad "LIGHT ENGINE". Call an Authorized Service Center and have them give you an estimate, then call MIT's and try to get them to give you a "CONCESSION". It's costly. Good Luck, big IRISH.

Purple blotches


Ok, so I'm about to flip a lid with my TV. I am showing purple quater sized blotches all over my screen. I bought it for a discounted price because of this issue, in hopes i could fix it. I took the back panel off the TV. ( about a 6in * 6 in plate) removed the light bulb and cleaned the bulb and lens, where the light bulb faced. I used a dust cleaner and special cloth. NOTHING! I took the entire front screen off cleaned it and then cleaned the mirror and second lens.... NOTHING! Then i heard that dusk sometimes gathers behind the lens and that should be cleaned. Try this, Its 4 screws, just be careful and remember the way you took it out, because it has to be replaced the same way.
