Monitor Problems

By robert.litwin ·
Has anyone ran into a similar problem with the monitor. What has been happening is that the monitor will go off every one to two minutes. The only way that we can get the monitor working again is to shut it off and turn it back on. Here are the things that we have done to try and fix the problem. First off we replaced all of the wiring to and from the monitor and PC including network lines. We even changed the surge protector on the machine. We change plugs in the room and moved the furniture around. We even replaced the monitor in the room and the PC itself. We called the electrician in to make sure it was not the electrical settings in the room. to avail all did not work. Does anyone have any suggestions? Thanks.

just do the obvious

by ProjManager In reply to Monitor Problems

This is what happens as a monitor ages. Some of the capacitors and resistors will begin to go bad. When they heat up, they have a problem that will go away when it cools down a little. Your best bet is to get rid of it and replace with a more reliable and less power hungry LCD display.

Check your Power Save Options first in O/S

by Why Me Worry? In reply to Monitor Problems

or if this is a fairly old CRT monitor (10+ years), the picture tube may be on it's way to the junk yard, as I have seen this happen to old CRT TVs' where the picture would cut out after a quick flash in the center of the display and the only way to recover from it would be to wait a few minutes and power the TV back on.

I had a flat panel do that recently

by w2ktechman In reply to Monitor Problems

After it warmed up (10-15 min) it would start flashing like that.
We ended up replacing the unit. The problem was with one of the controller boards inside.

More information after looking at sugestions

After looking through the power settings it is set to the standard settings of 20 for our facility. This is a LCD monitor and not a CRT. the controller boards are not the problem we replaced the system 4 times. the first thing we had in the room was a thin client and then we placed a new Dell System in to see if that corrected the problem.

There is still controller boards inside of a lcd/tft monitor.
One of the boards is malfunctioning, unless the settings are out of range.
If it flashes on multiple systems, replace the monitor and see if that fixes it. If so, the monitor is at fault. If not, then a setting is incorrect.

Try checking the Hz rating, as prolonged use at over 60 Hz can damage the monitor, even if it displays decently.

Ok, it is local to the computer

by w2ktechman In reply to after checking settings

turn off either Windows power management, or PM in the bios
Also, check the video card on that system. If available use another port (some lcd's have vga and dvi)

Exorcism anyone?

by TechExec2 In reply to Monitor Problems

"we replaced the system 4 times."

"when placed on other systems the monitor does not flash."

Your monitor sounds like it is possessed by a demon. Exorcism?

Seriously, if there is no apparent reason why it is not working in the one room (with different computers), but it is working on other systems (I presume you mean in other rooms), perhaps you should just use it there.

Sometimes you just have to make it work even though you don't know why. For example, more than once I've reordered PCI cards to resolve a glitch when reseating them did not work. Shouldn't make any difference but it did. Switching them back made the problem return.
