My monitor has suddenly been acting strange! When I turn the power on, I get the green power light however the screen (my desktop) flashes on for about a second, then goes black. If I look really close I can see images almost like functioning shadows of my destop I've tried replacing the 15 pin male cord, but to no avail. (my old cord has been tested on other machines and works fine) As well, I have tried switching ends, didn't work either. I cannot see the desktop long enough to adjust the menu on the monitor itself. Anyone else have this problem? Or is my monitor done? Any suggestions will help. Thanks.
Mine was doing the same had to keep turning it on and off to get it to work then it would not turn on at all green light flashed on and off on front of monitor. I unplugged monitor and green light on ac adapter kept pulsating on and off like a capacitor. I just replaced the ac adapter and am back in business with the monitor running good for tonight.
I guess these ac adapters go bad eventually.
Thanks From Tom

You need to change the capacitor
Hi, I faced the same problem in Sun. Can you please reboot your system and check. When I rebooted the display came. Bt again the same problem I found after 2 hours. Dont know what is happening Partha
Hi gogetemgirl, Based on your description/post, I'm afraid that it's your LCD monitor, to be more exact the backlight of your display. Inside your LCD is a thin florescent lamp (CCF) that provides the background illumination. This is powered by an inverter circuitry also inside the monitor. Though I would think that it is still economically reasonable to repair it, you would have to be familiar with component level repair, possibly the use of a VOM and a soldering iron as well as hand tools to be able to do a do-it-yourself. Should you seek the services of a qualified service professional, then it should be a quick turnaround (depends of course the availability of the replacement part). Hope this be of some help to you. Good luck and kind regards. PS. Since it partially work (albeit very quick only), it is also possible that there is only a cold solder somewhere inside the monitor. Still you have to open it up. Cheers.

same exact issue. that is of course, after a couple good years of use. tried the same things, the only way i can get it to work is turn it on and off 50-100 times and eventually if not at all it will work.
same problem here!! sometimes it will come on and most times rebooting does not work! would be nice to know if i have to replace the whole monitor or if it can be fixed inexpensively!!
My LM730 has been running fine for over a year. Recently, however, when starting from a power "off" condition (cord unplugged). the monitor will light up briefly (way under a second) and then show some faint picture. If, after much bad language and rebooting, it does restart - then it works fine until another power down situation. I don't have a repair manual for the beast and have not yet attacked it with malice aforethought.
I have the exact same thing happening. I can faintly see the menu and sometimes it has worked but I have been getting nothing for the past 24 hours.
