Attention no signal


Check this out with another PC to confirm the case before you can suspect the monitor. If so it can be due to failure of the signal processor within the monitor and so a hardware service is required for replacement of the IC.

Black display


You say black display. Not sure what you mean. Either the monitor is working or it is not. If you see nothing on the monitor and the power light is yellow, then it is not getting a signal.
If the power light is green and you see nothing, look really closely. You might even shine a flashlight at the monitor to see if there is actually a dim display. If so, the backlight has gone out and needs to be replaced.
I'm assuming that you have tried to brighten the display with the monitor controls.

My monitor screen is black. The green light is on but black screen


The green light usually indicates that the monitor is getting a signal.
The lack of a picture is an indication that the monitor itself is having a problem. I would test the signal with another monitor if you can get one.
I suspect that the monitor backlight has gone bad (if so, you can see the screen very faintly if you shine a light on it).
Or, the screen circuitry has gone bad.

Have signal, but no light, just one second screen can see and shut off.


Please clarify by shut off you mean power light turn off or just screen gone blank but power light remain on!

Mostly inverter(power supply) needs attention in such cases.

Display will not come up, screen remains black, blue light on front of monitor flashes on and off


Check that the monitor is still receiving a signal it could have gone into standby mode.
If not you either have a faulty inverter or the back light has gone, to test this when your computer is on is to check you can still see a faint image on the screen that means the backlight has gone, if not its the inverter.

Monitor starts then goes off, no signal


I would check the LCD against another monitor. It does not have to be a LCD, a regular monitor will do.
This will tell you 2 things, 1. The Video card is good or bad, 2. The Cable is sendinf a good signal.
If when you startup the monitor, you see a display and then after a few seconds it display's a no signal message, this is consistant with a Bad cable or cable ends. or Bad VGA card from computer.
Hope this helps. Good luck..
P.S. If you have move the PC, you may want to open the unit, and re-seat the Card. If the card is not making a solid connect on the board, it will display these syptoms.

Monitor turns green


This sounds like a problem with the cable. Monitors have Red, Green, and Blue signals. I have seen it where the cable has a short, or the plug has a bent or loose pin, and this causes the monitor to turn green.
It is also possible, but doubtful, that the video card is trying to run it as a Black and White monitor. B&W signal is sent over the green channel.

No picture on the screen


Hi,

I have this Panasonic PanaSync SL70 17'' monitor, I don't use it often. It is still in very great shape. However, I tried to turn it on yesterday, I got a black screen. The power LED is on and I can hear the relay is clicking when signal received. I tried to remove the signal cable, I can see it turns to power saving mode. It seems that everything works fine except no picture. I am if the transformer is gone, but not sure. I am wondering if you can help?
