Question about Computers & Internet

Monitor goes dark over and over

Here is my solution:
Around the time it happened I did a few things to my computer.
I had been trying NOD, it ran out - so I removed the program. When I did that my McAfee was gone. So, I had to go through their web help to get it back. It didn't want to just download again through their site. I had put in a trial version of Microsoft Office 2007. After I got that all done my java wouldn't work for yahoo games. All this was within a few days of each other, even the darkening of the screen, over and over.
Tonight, I noticed on my newly added McAfee, has a registry cleaner. So I used it. I also went into my program file folders and saw that NOD was still in there - deleted it and a couple of other programs that I had tried once, but, thought they had been removed through the remove programs, in the control panel.
My Monitor screen works fine and I was going to spend 200 on a new monitor. Dell 3153FPC flat screen monitor. The screen turns on at start up then turns either off to a black screen or so dim that you can't see much but the power light stays green. It's connected to a Dell Dimension 2400 desktop to the onboard video. I've updated video drivers, reset every card and piece of hardware possible inside the desktop, switched out monitor connection chords to the power and pc as well. This started happening after getting a new verizon fios wireless modem but issue happens with that hardware disconnected as well. I've ran spybot, avg8 free and hijack this to no avail. This morning, my daughter goes to turn on the dumb thing and it's starting up like normal with a perfect screen. It's the first time in 2 days we've gotten a steady picture though without the monitor blacking out. Any help would be awesome. I'm done with this thing.

    I have a samsung lcd moniter connected to an hp computer, we purchased the moniter and pc two years ago new. just over the past maybe two months or so, my moniter will go black if I leave the pc for awhile, I'll come back and wiggle the mouse and it will come bright again and switch back to black again. does this several times, I've tried turning moniter off and then back on and it will brighten for a few seconds and go dark again. if I click to connect to the internet and then click my browser on sometimes that will trigger it to stay on but it's getting harder to get it to stay not black. this started happening after I recovered my pc back to manufacturer specs. I also have verizon wireless modem but have had that for almost a year now and so it doesn't seem that is what has caused it. not sure how to solve it but I'm looking for info. if I find any solutions I will surely pass them on to you. :)

Try and find the LCD Screen diagram, there is a good chance that your capacitors are failing. The capacitors that will need to be replaced are the ones with either a bubbled top, you will notice these right away once you compare them to the rest. Or the ones where the LCD cable "from the monitor" meet the LCD circuit board. If this sounds to difficult its really not. you will a soldering gun and new capacitors. Radio Shack about .25Cents

Monitor goes blank less than a second after turning on.


Sounds like either there is a bad connection from the computer to the monitor, or the monitor has a faulty power regulator, causing the monitor to overheat prematurely, and shut off.

Monitor goes dark


If the power light turns yellow, there is no signal being received by the monitor from your computer's graphics card. The screen will shut off (go into idle mode), which is a low-power state, that saves energy. Check that the cable on the back of your computer is plugged into the right graphics card (many PCs come with more than one, these days). There may be one built into the computer's mainboard, and another one may be on a separate graphics card located somewhere else on the machine. Only one of these will work on startup. If one doesn't work, try the other.

Monitor Goes black, or flickers on and off


The high pitch sound is coming from the inverter. It is faulty and needs to be repaired or replaced. The inverter supplies high voltage to the CCFL lamp, this lamp gives the backlight to the LCD so you can see the LCD images.

Screen goes pink and green starting with a few pixels


Best thing to do, try a different known working monitor to hook up to the computer. If the screen works and doesn't change colors then you know its the original monitor that is bad.

If you hook up the known working monitor and the same problem happens then you know its the video card that is bad and the video card would have to be replaced.

Comes on for about five seconds and then goes dark


MAKE SURE THE CONNECTION BETWEEN YOUR MONITOR AND YOUR COMPUTER IS PLUGGED IN TIGHTLY AND CORRECTLY, YOU MIGHT NEED A NEW POWER CABLE OR A NEW CABLE THAT CONNECTS FROM YOUR MONITOR TO YOUR COMPUTER, TRY CONNECTING YOUR MONITOR ON ITS OWN PLUG, OR IN ANOTHER SOCKET AROUND THE HOUSE IT MIGHT NOT BE GETTING ENOGH POWER, IF IT IS NOT LCD MONITOR (NOT FLAT) THEN YOUR COMPUTERS BULB MIGHT CIRCUT WRONG
