    There is power to the monitor as the pwer light is ON on the monitor but there is no image on screen. If I press power button OFF on monitor and then press power button back ON I see the monitor and image on screen for just a sec and then monitor screen goes black.

    my monitor does the same thing. I power it on and sometimes you get a image and sometimes you do not. After turning it on and off a couple of times you get an image, but if you have to re-boot for any reason, again no image.

    Sometimes after the monitor has been on the picture goes completely blank and I have to turn it off then on again to get the picture back. What is the problem?

Do you have Schematic for my monitor


Hi
Dont think they are available any more. It's becoming a throw away world.
I used to fix them.... without a schematic. Your local TV technician can often assist with repairing an older style monitor. e.g. CRT tube type.
Modern monitors are LCD & digital electronics. Although they still blow fuses & have switch mode power supplies with leaky electrolytic capacitors that stop the power supply from working.
If your knowledgable in this field then I would start with a visual of the power supply. Be careful of the shock hazards.

Good Luck

The monitor goes dark within a few seconds of turning it on. Is this something that can be fixed or do I need to replace?


Try replacing the power cable. (assuming that the monitor has not lights when it turns off) After replacing the power cable if that doesnt work try a different outlet.
If there are lights try seeing if you can replace the data cable from the monitor to the computer. If that doesnt work then you will want to look into getting a replacement.

The hp mx 705 monitor was working,then it just went blank and black. the power button light, just blinks green.


If the computer is attached properly and you get the flashing lights it is due to switch mode power supply being faulty, too expensive to fix I think you will find, never seems to be anything like just a fuse I'm afraid, modern worlds tells you its time for you next monitor..... do try to ensure it aint the pc by hooking laptop or something else to this unit, or hooking another monitor to your pc to be sure but I find power supply failure is normally how monitors leave this world...

LCD monitor stopped working on my CPU but works on my Brother's


Definitely some electrolytic capacitors are blown inside the monitor in power supply module. Open it and observe any of them rounded on top, replace with proper ones.
You see, controller operations with VGA and DVI inputs takes different current from the supply, that's why it may take different time until PWM chip in the power supply will decide it is time to shut down before getting smoked.
Replace capacitors.

My Envision 7100 Stop Working


These are all some component failure problem in the monitor circuits. This may have been caused by faulty components or overheating of the components causing intermittent or permanent failure of some components in the circuits.This causes the feedback circuits to sense incorrect voltages or currents in the circuits and turn on the protection circuit. It may also cause total failure of the power supply circuit and a loss of power to the monitor. These units should be returned to dealers for servicing. Hope this helps you .

Ds-1107a inverter/power supply no power or comes on &LCDflickers


Classic sign of bad inverter. Since it is inside the LCD not something you can fix yourself unless you work with electronics. Needs to go to the repair shop.

Won't turn on


This is a problem with either the power supply or or logic circuit. It could also be caused by a failure in the back light circuits. One of these problems has caused the power supply to go into protection mode and will not turn on due to bad voltages sensed in the feedback circuits. Return to dealer for service. Hope this helps you .

Stopped working suddenly after 18 months daily use


It appears either the inverter supply board or the main video board have failed. First replace the inverter board, if not fixed, replace the video board. Mike
