NEC 77F CRT monitor - displays alternating black \ white crosses
When the monitor is powered on, it shows two perpendicular white lines that intersect the center of the screen on a black background. After 2 - 3 seconds, it shows black lines on a white background. It alternates from one to the other continuously, and I can't get it to do anything else (OSD controls make no difference.)
NEC has a monitor troubleshooting guide, but I haven't been able to access it.
I'm hoping the CRT is still good and that I can keep the monitor out of the landfill - what do you think's wrong with it?

Parallel lines are lines that go on forever and never cross. In mathematics terms, they have the same slope, but different y-intercepts. For example, y= 3x + 5 and y=3x +7 are parallel lines.
Perpendicular lines are lines that intersect each other at 90 degrees or at right angles. If y=5 and we are looking for a line that intersects it at 90 degrees (or right angles), the line would be x= 4.
Another example would be y = x. The perpendicular line would be y = -x.
To find the perpendicular line, the slope will be the negative reciprocal. For example, y = 3x + 5, the line perpendicular would be y = - 1/3 x + b.
Another way of looking at this is if you take the slopes of the two line and multiply them, you should get -1.
Your lcd screen has gone bad and needs to be replaced. To isolate that it's the screen or the video card borrow a monitor from a relative, neighbor, friend or co-worker and plug it into the laptop. If the borrowed screen displays fine without any problems then your original screen is bad. If the borrowed screen shows the white area with black leakage ink as your old monitor then the video card in the computer is bad.
Plug in an external monitor and see if thedisplay shows up on it. It can be any kind of monitor even the old big fat crtmonitors as long as it has a vga cable to connect to your computer's vgaport. If so that proves your video card is ok. The video will showon most systems when you reboot without you having to do anything. Some systemswill require you to hit the FN (Function key) + F1 thru F12. Hold downthe FN key then hit the correct key for displaying on the monitor (F1 thruF12). The correct key will normally have CRT/LCD on it or it will havethe icon of a display.
From what i can barely see it your photo it looks like your video chip (which is part of the motherboard's chipset) has died. It will be expensive to replace the motherboard.
To recover all your data is easy - just remove the hard disk from the laptop, put it in a case like one of these http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=2010010092%201053807124%201054107131&name=SATA then connect the case to another pc.
If you're referring to the taskbar that's usually on the bottom of the desktop, click on the taskbar and drag it to the bottom. Then right click on the taskbar and check "Lock the taskbar". This should solve your problem. All the best.
Not a solution at all, but I'll post that I have a NEC MultiSync FE700 monitor that I purchased back in 2001, and have I been using the monitor since that time. Lately the monitor has been showing signs of 'acting up'. I read on the Internet that CRT monitors generally have a working life of about six years. It may be, depending on years of use, that the monitors are just reaching the end of their life.
