Norcent LM730 Lcd Monitor Problem

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.

    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.

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

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.

Just bought a reconditioned monitor,a new adapter,and the green light comes on but the screen shows nothing? I checked out the video plus and they are in good. Help?


I would try it with another PC to make sure it is not PC problem. I would not open it up until you ask the person you bought it from to see what they can do for you.
You may have backlight inverter problem or lamp assemblies.

How can I get the Backlights for a Norcent Technologies LCD Monitor Lm730


Lamps: http://www.lcdparts.net

What is the problem with monitor?
Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums
Post back what you see inside so we can guide you further and it will help out other people in the future also.

Monitor picture goes off after start-up


Hello,

It sounds like you have a monitor with a common problem. After a few years some LCD monitors willblow a power supply. The problem is caused by parts called capacitorsoverheating in the confined space of he monitor. If you are good at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm Youcan take the back cover off your monitor and look for the badparts,replace any that look like the pictures and your monitor shouldwork fine. The capacitors do need to be installed with the correct + and-connections, note the stripe on the old one and insert the new onethe same way. If you don't want to try the repair yourself we offer a repairservice for $35 plus shipping. If your problem is not the capacitorsthen it would be the backlights and that is much more difficult toreplace.

I hope this helps, if so please rate my solution.

Monitor shuts off after initial start-up


My 17 inch Norcent LCD was doing the same thing. Then after a couple of weeks the AC adapter failed. I got a new ac adapter now LCD is working.
