Hello, I have NEC MultiSync LCD195VXM+ and when I turn it ON, there is just white shining LCD and nothing else. When plugged in power it came shining ON and after about five seconds its go into sleep mode (turned tubes off and power diode light orange). When pushed menu button, it came ON again. It will goes on even when you connect vga cable, so it knows that there is some signal. It even reacts normally on power button (turning on and off). As I see it that means that firmwareboard is OK. Powerboard should be OK too, if tubes are working normally. I even tried to disconnect all cables and reconnect - with no difference. From what I can see there is no damage to circuitboards.. no damaged capacitators and none capacitor plague.. Any ideas what can be wrong?

I have no idea, why is my question at Motheboards section. I selected Computer Components.

@ Solutions58:
Thanks for your solution, but thats not it. Graphic card is ATI 6970 and there is no point if the monitor connected or not. It is still clearly white. I have tried two computers and I can say for sure, that there is something wrong with the monitor.

I will add this information to my question and try to post it again under Computer Components. Hopefully it will be placed there. I have no idea, why is my question at Motheboards section.

I must have misread your statement. I was sure from what I read it was a video card issue.
If this is the LCD then is possibly the lcd controller (internal to the LCD monitor). You clearly have luminous to the screen so therefore the LCD controller and other components are failing or have failed. Usually these are electrolytic capacitors in the main board of the the Monitor and they have to be replaced. Also you could have diode and resistance that have failed at the vga connecting point on the LCD. I must have misread your statement. I was sure from what I read it was a video card issue.
