Monitor not activating

A computer monitor has a front-mounted LED that displays its current status and flashes in the event of an error. When an error occurs, the flashing may be accompanied by an error message on the screen. If the screen does not display an error message, the problem most likely falls into one of four common categories.

Unsupported Display Mode A video card has the ability to send output to the monitor at many display resolutions and refresh rates. However, no single monitor is capable of supporting every possible display mode. When the video card sends an unsupported display mode to the monitor, the monitor shuts off to prevent damage and blinks, or displays an error message. Standby Mode b> When a monitor detects no video signal from the computer, it assumes that you have turned the computer off and enters standby mode to reduce power consumption. Dell and HP monitors display an amber light when in standby mode. The status light on an Apple monitor blinks slowly. Incorrect Power Supply Some monitors such as certain Apple Cinema and Studio displays use external power adapters. Because different power adapters may have similar connectors, these monitors are designed to detect when an incorrect power supply is connected and blink the status LED rather than attempting to turn on. In the case of an Apple display, the LED blinks in an alternating short and long pattern. b> Backlight Failure b> A flat panel LCD display has an LED or fluorescent backlight that illuminates the pixels and makes it possible to see the contents of the screen. If the backlight fails and requires replacement, the monitor is unable to display any information. In some cases, you may be able to resolve this issue by turning the monitor and computer off, disconnecting and reseating all cables. If the monitor still has a backlight issue, it requires professional service.

a HP monitor. as old as 2006... (o0ps)
read the manual yet? on "power saver modes" turn off them?
i bet you dont know spec, on caps. it's not published by HP ever.
most are +80% - 20% for filters. (ever seen that?)
so a 100uf can read 180uF, or 80uf and is IN SPEC.
but no caps stated, by you, lots there are...
my guess you are
looking for the caps used in china long ago that all failed, every one.
first off you never fully stated whats wrong, in DETAILS.
first have good running pc , with live VGA output (using VGA are you)>? unstated...
the MON, will now live sync, now , Horz and vert, on both pins
the OSD screen now works, if not the monitor is bad.?
or see No/syn, no sig, out of range or no input errors.
Monitor Going to Sleep
see page 34? in your manual yet?
and page 31, turn of power saver ?
if OSD is dead, say so first.




OSD can be locked. push mon menu button for 10sec, now unlocked
then go to OSD screen

Power-Saver Feature
When the monitor is in normal operating mode, the Power li
ght is aqua-white or green (depending on model) and the
monitor uses the normal watts of power. For power us
age, refer to "Technical Specifications" (Appendix B).
The monitor also supports a power-saver mode that is
controlled by the computer. When the monitor is in the
reduced-power state, the monitor screen is
blank, the backlight is off, and the
Power light is amber. The monitor uses
minimum power. When the monitor is "awakened," a brief
warm-up period occurs before the monitor returns to
normal operating mode. The energy-saving reduced power stat
e activates if the monitor does not detect either the
horizontal sync signal or the vertical sync signal. The powe
r-saver feature must be activated on your computer for this
feature to work, << read that carefully?



turn this off ? first?
the early models of the monitor
had CCFL back lamps, and the 2 inverters are on the main power board. left side here

cable connection issue between computer and the display? Adjusted the cable? Tried another monitor? Safe mode works? If safe mode works, you can try to update the driver of the graphic card.

Power saving mode

Ok if it the monitor works fine on another unit discount it out of the equation as a monitor problem.
I would suspect the driver on the PC that delivers the problem, especially the video card.
. Check that the cable is also on tightly. remove it and even clean the pins and replug it .the plug on that PC may be dirty

You May need to replace the video card as the communication to the monitor is intermittent and that is why you get the amber light.
Open the box with power off. clean the card if it has a lot of dust on it ( most do and its always a shock) wipe it over ( BOTH SIDES) and then try to start it up as usual with the monitor connected to see if that fixed it ( sometimes works) if not get another card and replace it. Best I can offer without being there to help on the spot.
A new card should allow you access to install and configure it and these days they are pretty cheap to buy

Please rate this help to keep the service online

make sure that all the cables are connected FULLY.
blinking light means that there is no signal.

Your computer may be in screen saver mode, it has instructed the monitor to go to power saving mode, or the the monitor's video cable is not properly connected to the computer. Another possible cause of this is a locked-up or in-operative computer since the computer is what supplies the monitor with all the display data or information. Move the mouse or press a key to de-activate the screen saver or power saving mode. Check the monitor's video cable and make sure it is snugly connected to the computer. To see if the computer is operating properly, press the CAPS LOCK key on the keyboard repeatedly while checking the CAPS LOCK light. If the light is not turning ON & OFF, the computer is non-functional. Contact your computer manufacturer for help.

I think it maybe time to buy a new monitor

What kind of computer it is?
Dell /HP ??
Model?

Your monitor goes to Power Saving Mode when the signal it is receiving is not correct. In all probability this is not a problem of the monitor itself, rather you should check the connections and the computer the monitor it's connected to. For example you could try a different RGB cable and try it in a different computer.
