Question about LG L1930B 19" LCD Monitor

1 Answer

Monitor suddenly goes black

Working on line. Monitor suddenly goes black. The green button is flashing - and nothing else I do works. Have disconnected and reconnected all cables. Yet screen still black and green light still blinking. Pressing the other buttons does nothing. Seems as if it is in permanent sleep mode. I changed nothing. I do not know enough about computers to change things. Working and then - bam ! black screen.

Is this monitor and LCD flat Panel? If so this is due to a bad power supply, an inverter board going bad or LCD backlight bulb blown. When the backlight goes bad it gets just enough power to start up, but when it is on for a long period of time it goes black because the bulb is not stable enough to hold the charge because it is going bad. These bulbs can be changed, but they also can be costly!

Green power light comes on goes off then on again stays solid, moniter says no signal, mouse lights up, and three red lights on key board flash then nothing why?


If the monitor power light is on or flashing, but nothing displays, borrow a monitor from a friend. If that works, your monitor needs replaced.

I have a strong suspicion that you have burned a capacitor or two on the monitor. You will need to bring this in to have it serviced as it will require the monitor to be opened up and new capacitors replaced/resoldered.

The monitor will not turn on. When power button


First--was it working?
Did it suddenly stop?
When you see the LG logo, then it goes away, does the power light turn from green to amber? Sounds like that doesn't happen.
So--if you are getting a signal, you should see something.
If there is no signal, then the power light should change from green to orange.
With no lights at all, I suspect a faulty monitor.
