Purple blotches I notice purple blotches on the the screen with certain colour backgrounds,when I contacted Epson they told me it was dust on the optical head.Does anyone know how to the optical head so I can clean it off?

Anonymous Dec 18, 2007

Same Problem. The blotches are dust on some part that lies pretty deep inside the guts between the light bulb and the last lense that sits right behind the back of the screen. I took most of the tv apart to try to get the part that the dust is sitting on. I cleaned the back of the screen, the mirror and the last lens that sits right behind the screen. Did Not help. Not much help online. Epson will charge you $500 to clean it.

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.

So your final attempt when you took out the lens and cleaned it behind it did this resolve the problem of the purple blotches?You never stated the end result!

Printer will only print purple

on a colour printer, black is mixed with the other colours. Try printing a black and withe photo and you always get a colour cast. If your black cartridge is empty or the nozzles are blocked, you get bad colour and fussy prints.
test all nozzles, like is explained in the manual.
Check, if you know how to do, if nothing fell in the printer, that is now on the print head. Sometimes just dust or paper scraps are picked up by the printhead, making it difficult for the printer to print a normal page.

Screen turns purple and images do not come out

Maryelizabeth,

Unfortunately that sounds like the CCD (screen) is bad/going out. I would contact Kodak via the guided Assistant online repair tool here.

Excel Spreadsheet Chapter 2

Firstly you would need to select all the cells in the worksheet. (Assuming you have the worksheet that needs the change in format already open.)

Click on the rectangle between the row numbers and the column names ( i.e. to the left of the A and above the 1) - Marked as Step 1

Then make sure you have selected the home option on the menu bar you need to click on the bucket like button on the ribbon - Marked as BG Button. This should open the colour drop down thinggy that i added to the right of the image. Select the colour you need in this case for the purple I have marked it as Step 2 the Yellow is step 4.

To select a certain block of cells you need to click on the cell address area ( Step 3) and type the range of cells you need to select i.e. B3:B5 .. in this case its just 3 cells and can be selected manually by just clicking on the first cell and dragging the mouse to the third.

Finally jst as you selected the purple you could select the yellow colour.

Purple or magenta dots on centre of screen ,not noticeable at certain times. EMP-TWDI

My first guess is contamination on the lens or the internal LCD itself.
I would clean the lens first, and if that doesn't solve the issue, open the unit and clean the LCD panel.

I have yellow and purple blotches on screen

I had this same problem on my Mitsubishi rear projection WD52527 model television. The optic engine was changed twice, and the blotches were still there. It turned out that it was the mirror inside the television that was causing the purple blotches. It was filthy and once the repairman took it out and cleaned it the discolorations were gone. Hope this helps
