I painted light gray that now looks lavender on the wall...I am pretty sure it is the lighting in the room (CFL bulbs) as when I take the roller into another room with natural light or fluorescent lighting...


I painted for many years. And now work with photoshop each day.
The selected grey was probably in the blue family instead of yellow family. Most interior colors look better if they come from the warm yellow family, including greys.
There are greys for every color in the spectrum ... from yellow to red to blue. If you pick a grey with bit of red, it will start to look mauve. Orange and it will look brown. Blues inside the grey will turn purple real quick.
Moreover, all colors and finishes are contextual and pick up surrounding colors. Especially satin-or-shiny finishes, because they pick up local colors that change intended hue. For example blue drapes will turn white room bluish. If the house next door is red, and the light comes in window, it will turn white room into pink. Green leaves, and the light from window turn white room green. So when you pick a grey that has bit of blue, the color can change for many reasons beside light bulb. Each room is totally different.
Most folks pick colors by looking at color chip in the store, instead of painting a section of wall inside home. And most folks do not ask the paint store clerk which tints are in that particular color. Sometimes the black tint will turn some bases into a bluish hue.
Go back to paint store and get another grey color from the yellow spectrum.

Color changed suddenly, no red, just green/yellow/blue


Sounds like the color wheel has gone bad and needs to be replaced. This is located behind the back panel.

Blue haze spot-yellow tint


I have the same problem with blue haze that just spread out on model 55VS69A ,
tv is almost 2 years old. i called hitachi and they advised to call a local repair center to check the tv...they confirmed Optical Block (light engine ) replacement light engine cost $1400 and labour $400, so i called back hitachi and they said they will provide light engine and will have to pay labour!....this is not right paying out of pocket for a tv less than 2 years old....I am not sure if the issue will resurface again...more likely ....Hitachi is supposed to issue a recall or atleast like sony did to cover all cost for there defective TV's....I will NEVER buy hitach again.

Hitach SUCKS.

Yellow spot


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.

Take time to get used to the settings, you may think the screen looks dull at first. The truth is most people have way too much contrast on their TVs.
These settings will also work for Cable or Dish hookups, in which case you may change the Noise Reduction option to Medium to reduce signal noise.
