Re: monitor takes 1/2 hour to warm up

You need to check the fly back of your monitor maybe experience over heat. It is possible need for replacement but not the whole monitor only the fly back.

Hope you like my solution please rate me solved.

Samsung 793S (Black) 17

On these older CRT monitors when you have that type of problem it indicated that the high voltage power supply is not putting out the right voltage to charge the picture tube. As the power supply gets weaker the time to show a picture will take longer and longer. It is not worth repairing the unit because parts will run much more than a replacement monitor.

Please restart your computer and tap the F8 key as soon as you see something on the screen. You should get the advanced boot menu. Select Safe Mode from the list.

Let me know if you were able to boot to safe mode.

No picture, monitor won't show anything black screen. Monitor was working fine put it on another computer and it won't show images. Could it be part of the power saving system? Is there a reset button?

Does the monitor show absolutely nothing, not even when first turned on? In that case maybe the cable could be defective or connected improperly, or the new computer might not be compatible (or set to output to, say, digital port, while you've got a SVGA monitor). In that case you'll need to connect a working monitor for the time required to reconfigure the computer.

If the image does appears at boot, or resetting the computer, and then disappears, it could be that the new computer is set to a resolution which is too high for the monitor, which goes in protection mode and effectively turns off. Again you'll have to gain access to the computer (maybe booting in Safe Mode) and lower its video resolution to something the monitor can handle.

Hope this helps, have a nice day

You have capacitors on the monitors power supply that have changed value. Soon they will keep the monitor from turning on at all. Send it to a company like mine or take it to a local repair person.

Monitor image comes up, then blacks out, power still on

Hello David,

This is very common problem and is heat/age related, but It can happen to monitors that are no more than a year old. It is usually bad capacitors on on power inverter board. I just fixed two monitors with this problem. This problem is common across all brands. Look for several radial capacitors in a cluster on the power inverter board. If some are bulging or have a slightly domed top, they are the ones that are bad. I usually replace all the capacitors in this small cluster because some may be marginal. This is easy to do if you have a bit of electronics skill.

Image appears for 2-3 seconds then screen goes black

The following steps are how to examine what's wrong with your LCD monitors. After you turned it on and the screen went black, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. If you have soldering tool and want to fix it by yourself, check the caps first. It may cause this problem. Some caps might show leaking or burn spot on the board because of too high temp. If you don't have soldering tool, you better go get a technician to do so. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

Screen not appearing straight away

It could be your LCD backlight giving you problems till it warms up. Turn you computer on and while the monitor is displaying black and the power LED is green shine a flashlight in the lower left hand corner of your screen. Look for the ?Start? button, if your backlight is not working you?ll see a faint ?start? button if you look closely. A 15" LCD monitor is probably not an economically repairable problem unless you have access to really cheap parts and have the skills and tools to do the repair yourself.

Dimension of image change when displaying clear or dark image

Same problem Picked up this monitor about half a year ago, a Viewsonic A91f+, and have been having some issues for a while now concerning what appears to be shifting in the monitor image, but that is about the best I can describe it as. It is most noticable when a large dark area meets a light area, like text or window edges. This "shifting" only occurs on the right side of objects and seems to show most often after I switch resolutions more than a few times, usualy due to gaming. Ive also noticed it happening from running random programs that dont require resolution changing/flickers but this happens FAR less often. -photograph of the effect- As you can see, its pretty subtle on a darker background, but Ive had no luck carturing it on a light one. Anyone have any idea as to what is occuring on this monitor and how it could possibly be fixed? Possibly an issue with magnets? For a while, I did have a small headset hanging off the the monitor on the side that the images "shift" towards, but even taking those off and away havent fixed it. Currently the only fix I have found for this is to shut my monitor off for 5-30 minutes, depending on how bad the "shifting" is when I find a time break long enough to fix it.
