When pc is booted up, monitor light goes from amber to green, but screen gets no display, until monitor is manually switched off and then back on. sometimes monitor green light will switch off automatically and must be switched on manually to get a display on the screen. this only happens when computer is started from off. It doesn't happen when the computer is re-started. it takes several attempts to manually switch monitor on and off. PC is pentium(R) 4, 2.6 Ghz w/ 1.0G Ram

Pentium 4, you can get newer PC for $20 at Goodwill stores..
far newer.
why operate such old hardware, that being said.
no OS stated, we cant help unless you tell
what operating system there, Windows 2000,. NT, XP, Vista ? what?
what PC, the PC has service tag, HP tag, with a full model on the tag, telling again what you have allows the helper to help 10x better.
first off simple logic works here, its 2 pieces, 2 boxes.
one is monitor other is PC desktop (one is bad, for sure or cable)
the monitor is a relic of the past with a glass cathode RAY TUBE
in the year 2017, (fixed many back then/....) the carbondate is 2000
so its 17 years, old.
you can test in on any pc to see if it works but many CRT are not supported now on new machines,
any PC with a VIDEO jack called VGA.
warning, back in year 2000 the PnP system is fauilty or uses and old method not used now, so mixing old with new is not wise. or
not a valid test, and the sleep mode rules changed 2000
the "VESA" spec evolved.

the monitor has an OSD, if the OSD is dead , at any time
the Monitor is no good. it has push button on the front
called select. or menu,, On Screen Display, OSD,
it makes its own special menu there, even PC turned off.
monitor on.
with PC off
You can also plug in any working VGA monitor in to this unstated
Pentium box. and see if that BOX works in 5min work.

here is test 1,
turn on the monitor
and push the menu buttons on the the front of monitor
you must get this, or the MONITOR IS BAD.
sure power cord good. powered on, and power at the wall jack good.

i just googled you manual and read it, in 16sec flat.
and here is mr OSD,

when pc is booted up, monitor light goes from - 75-hxtzib5ixwoiaxej5xouicye-3-0.jpgblack screens happen
here is all ways from sunday black screens of Deathh

"monitor green light will switch off "
out means lost power. or the MX75 intenal power supply is dead, or line power is dead. AC 120vac, lost power.
yell means sleep.
if out means blank, (not green/yellow)
that means the monitor is BAD.
time to get a new one.
walfart has em on sale.
for a whopping 40 bucks, the price of 2 potted plants.

    rtm here, read how it works
    how to get menu.
    page 6 tells you yellow power led is sleep mode
    if the cable is pulled it goes to sleep.
    if the PC goes to sleep mode, the monitor goes to sleep (black screen)
    but the OSD alway always works.

    page 9 teaches the SELECT button use
    push it and OSD pops to the screen.
    do so and report. this is first, always.
    if OSD is dead, so is monitor.

  • Anonymous Jun 03, 2017

    OSD works" check
    Monitor works on other PC, check
    means what, the PC has problems. As geeks say "has issues" (the PC box)
    PC can fail in vast ways, i can list 3million
    but is what?(macro mode. the modular view)
    1: PSU dead.
    2: mobo dead.
    3: VGA card dead, or cant handle CRT relics. (vast )
    4: wires fell off or bad.
    5: windows (not stated) stuck in sleep mode or hibernate mode or virus infected, or drivers wrong.for VGA. GPU chip there.

    we have tests for each,
    many just guess, (swap parts)

    id bet its infected, never seen XP or older not fully infected with virus. ever.

SOURCE: blank HP w1907

If the power light does not turn color and stay's green on startup, it is not a power problem. It is most likely the inverter. If the unit is in warranty, send it out ASAP. Contact HP customer care by email and have the issue logged in.
If in warranty, they will send you a box by FedX second day and have repaired.
This is a 19" monitor and will not be worth paying for repairs if not in warranty.

SOURCE: Monitor turns off: Light goes from green to yellow

The first response was my first thought. However I dont think you need a new monitor, check to make sure your computer is not set on some kind of power saving option. :)

SOURCE: Going to Sleep

Due to the power surge, it is highly possible that the monitor was given a boot by your computer on it's way out.

This will short out a very small transistor inside the monitor on the video board and in turn, then monitor cannot see that there is a signal so goes to sleep.

If you get brave enough to venture inside the screen, then check near the cable input. The transistors are only around 3mm and have 3 legs (two one side and one in the middle on the other).

If you find anything like that burnt (get a magnifying glass) then replacing the board is the easiest option. Just don't be tempted to wipe the board before you look at everything very closely, you may wipe away the tiny bit of evidence you are looking for.

Hope it helps =)

SOURCE: Monitor goes standby after boot

Look the problem it may not your monitor it's your windows XP. Let me guess you have a VGA/Svideo card. From prior experience I can tell you that dual output Nvidia cards will default to Svideo first, and then "adjust" your windows settings to do so every time even if a VGA monitor is re-connected (HIGHLY ANNOYING). So if the last thing you see before nothing is the Windows XP boot screen, here's how to fix it. Boot to safe mode uninstall your video driver, reboot then reinstall. You can substitute a system restore for uninstalling your drivers if you can remember when the monitor was last working. This really really pissed me off when it happened to me.

My GX520 pwr light is green, on the board is an amber Led, the somputer boots up, it goes the full process, until the arrow appears on the monitor. no Iconn are displayed on the desktop

If your computer gets to that stage, then I would guess you have an OS ( Operating System ) problem. Try booting from your XP installation CD. If that works then you may have to re-install Windows.

My flatron L1710S flat screen will not come out of power saving mode. When I turn on the monitor the power button/light is green for a few seconds, the screen indicated "power saving mode", then...

I switch on my PC, ensuring that all cables, leads and power supplies are connected properly. The tower powers up no problems at all. I switch the screen on, the green led lights up, the screen is completely black. A blue box appears centrally on the screen with the text 'power saving mode'. The green led light turns amber and then the screen just goes black.

Please don't suggest going to control panel, as I can't get that far.

No sign of life from the display half but the bottom reads life.


If you have already checked the connections from the screen to the PC, check that you have a power light on the screen. (Green or Amber). If no light, check power to screen. If it is amber, then the screen is not getting a signal from the PC - recheck connections. I would suggest you try and connect the pc to a different monitor to check whether it is the screen or the PC.

If it is the same on another Monitor or if the power button is green on the screen, then the pc is not sending information properly. Turn the pc off manually by holding the power button on the bottom half for about 10 seconds. All lights should go off from it. Now turn it back on again and see what happens.

If you see loading windows and then goes black, do the following:

Turn off the pc (bottom half). Turn back on and as soon as you pressed the button to turn on, start tapping the F8 key until you come to "Windows Advanced options" screen. use the arrow keys and go to Enable VGA mode. Press the return key twice. If it loads to windows, then fine. If not, then you may have a problem with the display adapter.

Hope that helps

Dell dimension 5150 blinking amber lights

I have similar problem these days. After normal shutting down the PC, it can not be powered up again, the amber light blinks. A temp solution for my case is by doing these steps:

1. leave all monitor, network, keyboard and mouse etc. connected
2. disconnect the power, wait until green light and amber light dim.
3. pop up the CMOS battery, then put back in (better to check its remaining voltage, if not good, change a new one)
4. power amber light flash shorter and lighter
5. disconnect any USB connections like keyboard and mouse,
6. immediately connect keyboard and mouse back into USB ports
7. my pc powers up at this point, all green lights shining. Except it displays CMOS setup warnings, give me options to click either F1 or F2
8. I click F1, it goes into normal login XP

The only problem is I could not shutdown PC again, if I do, then I have to repeat 1-8. I have to use "Standby" instead, which I usually do.

Monitor Acer Problem

I agree it isn?t the monitor but I would suspect the video card you are connecting it to or the PC itself. Generally if a monitor doesn?t detect a video signal it will go into hibernation mode, typically displaying a no signal warning and changing the LED color from green to amber. When you start the computer is anything displaying at all? Are you sure the PC is powering up and booting?
