Question about KDS Xtreme XF-7s (Silver, Black) CRT Monitor

2 Answers

KDS xf-7s, vertical lines

I have had vertical lines in the middle of my screen for some time now. Before, they only did this when I shut down the monitor. They would appear and then disappear. Now, they are there all the time and more prominent. I can barely see what is in the middle of my page. My monitor is only about 3-4 years old. How can I fix this? I have tried every fix that is on my monitor and nothing works. Please help. My email address is Thank you.

I am sure you have open the casng of the monitor.
Try to look for cold solder ( dry solder ) pin around the horizontal yoke connector and touch up the solder joints.Or either horizontal yoke coil is open.
Caution: not to touch if don't have knowledge of the circuitry .
Solder it the while power is off.
The input is 240v AC and output at the Anode Cap Appox. 28000 volt for 14 -15" monitor.
Have a try.

Monitor has vertical lines down right side of screen

Check to see if there is dust in the vents on the monitor. Blow them out with canned air or dust them with a brush the best that you can. The lines could be caused by over heating which usually happens when the vents are plugged by dust.

If this does not solve the problem then the monitor has overheated to the point of burning pixels and needs to be replaced. Over time the lines with grow wider and wider until they cover your screen.

When watching movies on my computer, I am getting a weird line through the middle of the screen at times, also, when things are moving on screen faster, more lines seem to show. I guess they don't really...

i think your vertical IC ( if vertical lines are shown) / horizontal IC ( if horizontal lines are shown) of your monitor has damaged. you may contact a mechanic and change the corresponding IC

Kds model 780 monitor no signal, power button does not work

My monitor does the same thing at times and sometimes shows "No Signal" and at other times the screen will maintain the images but the backgound color switches to mustard yellow. In each of these cases I have been able to solve the problem by unplugging the power cord from the electical outlet for about three seconds and plugging it back in. I have a KDS model 780 LCD.

KDS K717s 17" LCD Monitor

The white screen tells me that the display cable (inside your monitor) may be unattached or broken.
The color bands if they are vertical or horizontal lines tell me that your display cable needs to be replaced.

So overall replace your display cable. If this doesn't entirely fix the problem your logic board (inside the monitor) needs to be replaced.

This indicates that your vertical sweep has failed and the auto protection circuit is shutting down the video so you do not permanently burn that line you see into the phosphor coating of the CRT.
At any rate, the vertical sweep circuits need repair before the unit will work again.
Good luck.
