    I thought my monitor was completely dead but when I plugged it in today the led power light blinked a few times but the monitor still didn't come on. I make sure it is plugged into a working outlet and it is not plugged into a computer.

    Any ideas?

    I have a Gateway FPD1975W 19-inch. The power light will flicker on when I power it up then the monitor won't come on. The warranty just expired and Gateway won't service the monitor. Any suggestions on how to fix it or get it repaired.

    Usually when the cable is disconnected the led is yellow . Tried to connect to another computer and the result is the same.

    I have 2 X2Gen V19 monitors. One of hte monitors has periodically gone out, but i could fix it by simply unplugging and plugging it back in. Today, it went out and the normal fix doesn't work. However, when i plug the monitor into my other adapter, it works, which suggests an adapter problem, not a monitor problem.

Hi, My picture just collapsed and the power light went out. The mains lead and the surge fuse on the main board are both ok, there are no visual signs of damage but there is a ticking sound which only stops when the mains lead is pulled out no matter which position the on/off switch is in. The CRT cathode heaters are NOT lit, so could this be a Low Tension problem?

Blinking light on 20 inch apple display

Blinking light on Apple cinema display usually indicates insufficient power from the power supply. Test it with another power supply from ANY cinema display (23" and 27" power supplies are ok to test with).

Sudden failure - working fine then next time switched on no apparent power (no indicator light on), no display

You could have a power supply problem in the LCD monitor.
First check the power lead, make sure it is firmly inserted into the mains socket and into the monitor.
Try inserting it into a different main socket that is operating, to see if the power indicator LED lights up.
If you have determined it is the LCD monitor is faulty, then it requires repairing.

if there is no power getting to the monitor ( indicator light ), test the fuse in the power lead first.Ensure it is inserted tightly.
If there is power to the monitor, the green indicator light should be steady, if it is flashing there is a problem with the display

Test the monitor in another computer or laptop.

If t stays black , I'd supect a faulty backlight or more probably a blown power capacitor whih will need checking and replacing

The Dell AS 501 monitor display comes and goes off in seconds. If I switch off and on again, the display comes back and goes off again in less than a second. I repeat this as many times the same monitor...

This sounds like the power inverter is failed.. It's what pumps up the power for the light in the monitor.
You could try unplug the sound bar from the back of monitor if you have the sound bar installed. Just a maybe..
To fix the inverter (replace) is usually better to buy newmonitor unless you do it your self.
The defective LCD Backlight inverter will cause the following symptoms:
  • No Display, but Power Indicate light stay on green (Or Blue).
  • Screen flash on and off and the power indicate light stays on green (or Blue).
  • Dim Display
Go here to start looking if you want to try yourself.

X2 gen 17" lcd monitor, no display

This indicates either a problem with the monitor cable(ie shorted) or the display adapter. Try plugging the monitor into a different computer and if it works you will need to install a new display adapter in your computer. If it doewn't work on the new one either you can try a different monitor cable if yours isn't permanently connected. Hope this helps

No display

if your monitor is not connected to a pc, then it cannot find a vga signal input and therefore go into power saving mode, which is indicated by the orange light, but as soon as you connect to the pc and power on the light will go green and the monitor will power up.
