SOURCE: F-17 neovo monitor stopped working. power light is flashing yellow

The flashing light indicates a diagnostic state called protection.
When the Monitor goes on protection there are only two possible causes.

1 The internal circuits are jammed because of electrostatic charges accumulating on capacitors, or because of a wrong voltage read by the main chip on your monitor controller board. this started the protection circuit.

2 The protection circuit detected a wrong voltage or a broken contact, identified an internal fault and kicked in , starting the flashing light.


If you are in situation one, then the monitor will reset just unplugging power cord for one or two hours, sometimes even minutes.

If you are in situation 2 , then there is an internal fault.

Common faults that can occurr suddenly are a blown capacitor on power board, the inverter board powering up backlight lamp has blown, or a fault on main lcd controller board.
check also the video cable, if the cable is shorting, or the connector is bad, you can get same flashing state because of the video cable.

Check connectors, try moving the video cable, and if the cable is not built in, then also try a replacement cable.

SOURCE: Samsung monitor blue flashing light, black screen

Hello,

The picture board of your monitor has developed fault. That is why the screen is black.

The best thing for you to do now is to take the monitor to a local repairer within your vicinity, because the fault is not something you can fix in other not to complicate issues..

The repairer will help diagnose and replace the faulty picture board and your monitor is back and better.

Take care.

Hyundai U220WD LCD monitor displays OFF MODE (on a black backgroung). How do I restore the display? What does the MWE button do?


Hi
If the screen is connected to a computer usually its a video card/ video cable problem and not the LCD monitor. Try to check the video cable look for loose connection or bent pins, if none try using a different video cable or checked the video card component of the computer too see if its still working,. Your monitor is dependent to your video card signal inside the computer. Without the signal monitor will not work.
thanks for using Fixya

Be sure computer is actually starting. Power off then on computer you should see the boot sequence and then windows screen on monitor. If you do not see startup sequence monitor is not sleeping either the monitor has failed or the video card has failed. Try another monitor first.

Hp pavilion f1703 blue monitor power button flashesw/ dark screen


Have you tried connecting this monitor to another computer, even a laptop. This would tell you whether the display is bad or the video card is the culprit. I suspect the monitor's power supply is dying. Taking it to a pro for repair should cost @55.00. Buying a new monitor @ $100 - $125.

LiquidVideo L17LCD2 17 in. Flat Panel LCD Monitor - Power Issues


firstly stop turning it off and on because you will blow something else like a power board then it will be a big paper weight.
next get a torch and when it is powered on and supposed to be showing images, shine the torch at the screen.
if you can see everything then you have a broken backlight or problem with your backlight and connections.
they cost approx £15 and a little labour, its not a big job. you may be able to do it yourself if you can get hold of a service manual.

Flashes on then goes black


The green light only lets you know there is a valid video signal reaching the monitor. If the green light was not "on" your problems would possibly be within the pc itself. Something is not holding the circuit for the backlight "on" thus going black. Suggestions are: 1. Take it to get it repaired (if not under warranty) Hyundai carries a 3 yr warranty on this monitor. Website provided. 2. Buy a new monitor http://www.hyundaiq.com/Eng/Customer/CusSvc/Csvc.asp
