My photographs have a purple and green hue instead of a red and gray hue like what it looks like on the laptop screen, any suggestions how to make the printed picture the same as what it looks like on my screen? I have a Epson R340 Stylus Printer and a HP laptop

Your hair is turning green because your missing red when you color your hair. Gray is uncolored hair and to get to a dark chocolate brown you need to add a little red to the color to make up for this. You don't need to strip it out.

Have you heard of people using purple shampoo to neutralize the yellow tones of their blonde? Red will neutralize the green tones, so adding a little red to your color will do this for you.

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.

This will depend on the brand, model, cable connection type and OS of the laptop. Most have a color control which you can adjust.

Hi,
This kind of problem occurs if tv screen got hit by some thing that damage internally and its irreparable, second possible cause is magnetic field nearby screen, please check any speaker or some thing that has magnet inside around tv, remove it from tv to fix purple hue at top of screen.
Unplug tv from AC wall socket for 20-25 minutes, replug back in and turn it On, this will demagnetize screen to cure the problem.

I just purchased a Sony SLV-798hf VCR secondhand. It did not come with a remote or instructions. Thus I'm unable to set time or use the record function. I tried getting a manual online and was unsucessful.

Sorry to tell you but you are describing exactly what an LCD looks like when it has been fractured. Does it work with an external monitor? If so you will need to have it repaired. Call the Fujitsu support number (800)-fuj-itsu and they can tell you where a repair center is in your area. The call is free. Have your serial number handy.

haveyou tried shutting it down and restarting it? it may just be the screen going bad

1)Please verify your model # from back of set......

2)Reduce the color to minimum or tune in a black & white chan.
you should see gray, not yellow hue

3)Remove lower front grill cover & access panel.....locate the
focus / screen control block...turn blue screen control slightly
CW......red,green and blue must mix to equal gray

4) reset color to normal level.......reassemble

I have the same problem. Just spent £50 on a new print head which did sod all. I suggest using an maintenance hammer then buying another printer.
