This is the way how to examine what's wrong with your LCD monitors. After you turned it on and the screen to dark, you have to check that if you still 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,

My Dell monitor is hooked up to my MacBook Pro so I can watch the DVD on the bigger screen ( the Dell ) however the screen lights up but the DVD will not show on the screen


Don't know much about Macs but with Windows based PC's the external connection to ta monitor will not display, unless you change a setting to tell the system to send the video to the external connection. Perhaps in the Mac there is a similar setting you need to change?

Hi! Just want to ask how can I connect my viewsonic monitor from computer to dvd player?


Get an adaptor, you don't say what model of monitor you have so I can't be more specific, You will probably also need speakers from the DVD player to get sound and an amplifier and the correct leads. But why bother? if you want to watch DVDs on your monitor then play them on your computer.

Power light is on ....screen is goes black after a few second of the monitor being turned on


There's a good chance you have failing electrolytic capacitors either in the power section or the inverter section or both.
Any caps in these sections that look bulged at the top, or bulged/leaking at the bottom need to be replaced.
If you repeatedly turn it off and on, eventually it'll probably stay on, but every time you turn it off, the TV will get harder and harder to start up until one day it just won't.
Sometimes you have to do the opposite to start it up and unplug it for some time and then try again.

If you aren't tech savvy, don't worry, read the rest of this solution and watch the videos.

If you are handy with a soldering iron and can identify the power supply and inverter / FM section for the backlights, an inexpensive handful of capacitors will likely fix you right up.
Match the capacitance on the capacitors. Go over voltage if you can, and still have them fit.
IE - it's not a bad idea to replace a 10V cap with a 16V or 25V or even a 50V, but don't replace a 680uF cap with a 500uF or a 1000uF (unless you are positive it's only doing ripple filtering, and even then, you should go OVER, not under the uF rating).

Most of the caps that go are 10V 1000uF or 3300uF.

I found some great videos of the procedure (for many Samsungs with the same issue) on youtube.

As you can see, this issue spans plasma TVs, as well as large and small LCD TVs and monitors.
The parts are cheap, and skill required is minimal.

Open up the Control Panel and double-click on the Power Options applet. Change your current power settings so that the monitor will not turn off after 20 minutes of idle time (set it to Never).

Screen went black


I don't know. I've never actually replaced parts in a monitor. If the bulb is expensive, it might be best to buy a new monitor. They're cheap nowadays. Or you can check if there's warranty on the monitor and it can probably be fixed for free.

Horizontal lines on my monitor


I have a similar problem with a 2 year old Samsung monitor. I have tried to make a screen dump of it, but the horizontal lines do not show up then. This I have read indicates that the problem is in the monitor and not the video card.
