This problem started a week back. I have a Emachines T3522 PC desktop (2 years old) with Windows XP pro (with latest service pack). When windows boots, the monitor comes on for a few seconds and goes black. The monitor on/off switch still glows blue (which is ON). If I switch the monitor off and on then the screen reappears and then again goes black. If I do this a few times and somehow manage to keep the display stay on then it never goes black again. All along my PC keeps on working fine i.e. I can hear the PC and fan running. Also as I keep on switching the monitor on and off I can see that the windows log in page appears etc. etc. i.e. the PC carries on with its booting job. I have the Intel 910GL Express Chipset display adapter. I updated the driver from Intel site but still the problem remains. Any suggestion will be greatly appreciated. I googled and found no answer and also found that my problem is a bit unique in the sense, once I can manage to keep my display not turn off by switching the monitor on/off then it stays on and the problem goes away.
This PC was sold new day1, in 2009 (a bad year)
and as such had (per your manual) has toxic mercury CCFL background tube lamps at the LCD screen that do just exactly as told so very well.
and PC means Personal Computer
and CPU means central processing unit, a chip a USA invention !
when the screen is black we use the flashlight test (uk torch , burn free, lol.)
point it here.
see data the CCFL? yes, are dead and the do fail intermittent or by hot and cold room. or dead or dim or got yellow for white tinged.
the problem is bad hardware and googling finds endless geeks that do not understand hardware at all, or little (i call em bit flippers)
Too bad all makers of PC and monitors did not put screen test mode button on the PC, that glows the back lamps
in our shop we use HV CCFL tester to find that truth easy.
the monitor is bad on the desktop PC
if you test the monitor on 2nd PC it fails
if you the failing PC with known good monitor the PC passes all test.
now you learn 3 simple tests, of vast.
but in order based on AGE
big clue #2 is monitor newer showed its ERROR NO SIGNAL or NO connection error, so that clue means PC did not die the monitor did.
no signal , no connection, no sync, or over-range errors never seen.
fans normal. blowing. in PC is clue 3 (and all LED you told too)

Have you found a solution yet? I just posted the same problem with my E15T4.

Hi there Eliot.
It does sound like a graphics issue, go here and select "downloads" for all the drivers for that computer .

SOURCE: LCD monitor signs "no signal" on eMachines t3418
E-machines had had a long history of bad power supplies. I've seen many of these machines go bad and when they do they take out the video chip (Nvidea) with it, usually shutting down the whole machine. I've never seen one operable. You might be able to insert a video card.
SOURCE: monitor screen picture won't stay on for longer than a second
I had the same problem with my eMachine t3418. Site advisor Micromend suggested changing the power supply to more wattage. Very much recommend doing that. I did but it didn't fix the problem. Micromend also advised trying a video card. I bought a cheap vid card and installed it. It worked. Apparently MY problem was in the motherboard and the vid card worked around that. Much cheaper than replacing the computer. I'm NOT a tech. Just sharing my experience with what worked for me. I you have a laptop or a friend does, hook your monitor to it to test that it's okay first though.
SOURCE: Black screen on my desktop, and connect pins are broken & bent
You'll get either no signal or missing color(s) if pins are bent or missing.
Carefully bend pins back with small needle-nose pliers. Pin 9 is missing by default - if any other pins are missing or broken, you'll need an expert to wire a new VGA plug.
