Black (non-usable) screen on 1/3 of entire computer screen

They are caused by a component in the toner cartridge.

Originally the cleaning roller was a plain roller, but at some time the 'bean counters' decided they could save a tiny bit of money on each cartridge by using a spiral foam roller instead. The foam also seems to be of a different type, and doesn't age well.

There are two solutions.

1. Replace the cartridge that is producing the coloured squiggle/


2, dismantle an OLD cartridge and if it has a plain (non-spiral) foam roller, swap that (along with it's supports - the new type are a different size).

Either of the above will cure the problem, but a new replacement cartridge may also show the problem in time, as it WILL have the spiral cleaning roller.

It's possible that the Cyan toner is low or depleted. If so, the printer will print the blue areas in black. This is a possible way to check:

1. Open your Applications folder and double click on "System Preferences."
2. When it opens, click on the printer icon with "Print & Scan" underneath it.
3. Click on the HP2600 printer on the left, then click "Options & Supplies"
4. Click on "Supply Levels." Check the Cyan toner cartridge. If it's low, then you'll have to buy and install a new one.

Here is a link to the HP cartridge page.

You'll have to consult the information that came with the printer on how to replace the cartridge.

Liquid Crystal Display - LCD
There is a Flo recent light that shines behind the screen. This light is what passes through the window or LCD when the shades are open or partly opened.
Think of each colored individual LCD (pixel) as a Window Shade. You have pixels that are made up of 1-red, 1- green and 1-blue light shade.
Your main control board will tell each light shade how much/far to open each colored light shade so it will make the color it needs to.
If the shades are closed (black) if the shades are all open (white)
Hope this helps.

Setting the font type color in a Microsoft Office Word document to black will ensure that the document prints the text in black. However, if there are images, graphics or photographs within the document, they will more than likely print in color or hued colors similar to black. To ensure that the entire document prints solely in black ink, you must set the color settings on your individual printer to black-and-white

Instructions:
1.Click "File" and then "Print." To open the print dialogue box using keyboard commands, press "CTRL" and "P" simultaneously.
2.Select the printer you are using at the top of the dialogue box under "Printer" and "Name."
3.Click the "Properties" button next to the selected printer. The dialogue box that appears is different for all users, as it depends on the type of printer being used.
4.Click on a tab, button or selection box indicating "Color." Most options include high-quality color, grayscale and black cartridge only. Choosing grayscale will print the document using various shades of gray and other tones such as blue or green that match the actual hues in the document visible on the screen. A photo or picture that may look black or gray could actually have blue undertones. To print purely in black and white with no undertones, you must select either "black cartridge" or "black and white only."
5.Select "OK" to return to the Microsoft Word printer dialogue box. Press the "Print" button to print the black-and-white document.

I hope you find it very helpful. Thanks.

Hello,

It is the picture picture board on your monitor that is malfunctioning, since the power led or button is on, but blue shaded screen, it means the picture board of your monitor has developed fault.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity or any service center to help with the replacement of the picture board because the fault is not something you can fix yourself, in order not to complicate issues.

Take care.

HI, Check the menu set up of the TV. There should be an alignment feature that aligns the blue, red, and green colour projectors. If the blue is out of alignment that is likely why you can see it on the dark backgrounds. The set up normally puts a white cross on the screen and you select each of these colours and then move the cross over the white on with the arrows on your remote. Once all are aligned correctly you shouldn't be able to distinguish between different colours and hopefully this should get rid of your blue shade.

Yaps those are because of magnetic feilds around the monitors and TVs, try moving it to a safer place.

THE CABLE INPUT IS SERVED ON 22" VIZIO HOW AND WERE CAN I GO TO FIX THIS PROBLEM IN ATLANTA

from what your saying, it may be that your monitor may be going bad and may need to be replaced.

I suggest calling dell and try to get your monitor fixed,
or you may buy a seperate monitor, just make sure it has a VGA port so that you may use the monitor.

if the tv has a portal on the side open it up and make sure the screen is not out of it's track, don't set anything on top of the set it could make it happen also
