Question about NEC MultiSync 77F 17 in.CRT Conventional Monitor

1 Answer

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?

    I didn't think any of the buttons were stuck, but I pushed all of the buttons on and off (with the monitor turned off), and I connected the monitor to a dual-monitor setup. I was thinking that maybe I could get the monitor unstuck if I could change the resolution (or something like that.)

    The monitor worked perfectly as soon as it was powered on, so maybe it was one of the buttons. Thanks for the suggestion AKAShadow, it seems to have worked.

Sounds like its stuck in test mode. Make sure that none of the buttons are stuck in place and does it make any noise while its turned on?

What is the meaning of perpendicular lines


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.

Let me know if you have any questions.

Good luck.

Check the cable going into the back of your monitor and the cable from your monitor into your computer, one of them is most likely loose.

HP pavillion dv9000 has black horizontal lines across screen and looks like a snowy background


Sounds like the screen is going bad. Isolate the problem by plugging an external monitor to the laptop. Borrow a monitor from a neighbor, friend, relative or co-worker to plug to the laptop. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If the Borrowed monitor does not show the black lines and snowy background, that proves your video card is ok and the problem is your lcd screen. If the borrowed monitor shows the same black lines ans snowy background it means your video card inside the computer has the issue.

The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

No true black appears to be available


Try this:

Turn the monitor on. Make a background picture of a black and white checkerboard pattern.

Press and hold the 1, up and down buttons. A small icon will eventually show on the display and the monitor will do a white ballance.

It can be hard to get the monitor to do this sometimes. Just keep trying until it works.

Note, you should open the monitor and look at the caps in the power circuit. They may need to be replaced. Better now than later.

Blue out of focus; casting blue "glow"


Try changing the coolant in the blue tube. Contaminated coolant will give a halo look to the affected tube and you will experience difficulty focusing that color.Phillips/magnavox's blue is the tube most often affected with the contaminated coolant issues.

Squiggly lines in the center of the monitor


sounds like you have what are called dead pixels. This typically happens in monitors that are about 2+ years old. If you are still within warranty i would contact hp about getting it serviced.
