Hi alonzot,

Here are some basic steps that will help you fixing the problem.

I'm assuming that your unit is dead set without an standby LED light and your outlet is live.1.Power cord - check the cord it might be opened (no continuity).This is due to frequent bending,pulling. 2. Power switch - check for dry joints, open contact. 3.Check the internal fuse- sometimes the fuse fail because of the power surge, replacing with new one will cure the problem, If this is the case I would advice you to use surge protector/AVR (Automatic Voltage Regulator). However if the fuse blew again this is an indication that you have a shorted parts in the power supply, you may visit the linkhttp://www.fixya.com/support/r8053361-fuse_keeps_blowing for more info. If no reaction and still the unit didn't power up then you have an open parts on the power supply.

4.If you see that the fuse is intact , don't attempt to touch anything because there some fatalcomponents stored electricity enough to hurt you with a simple mistake only. I would advice you to look for a professional to troubleshoot the power supply. If you want to repair it yourself make sure that you have necessary tools and test instrument. First check bad solder joints(re-solder all cold solder), leaky electrolytic capacitor(sometimes it has bulged at the top but not all, you better have a capacitor checker), open/shorted regulator transistor/IC(mounted in heat sink), open fusible resistor (caused by shorted regulator Transistor/IC), shorted zener diode.

You may also replace the power supply board, try online like ebay.com and shojimmy.com.

Also check if your unit is under warranty before opening the back panel, it will void the warranty. Avail it because the manufacturer of your unit will fix it for free or a little charge only.

Hope I helped you.

Have a nice day!

Thanks for using fixya.

mohanjith, First thing to investigate is the lcd monitor internal power supply for failed electrolytic filter capacitors on the power supply circuit board. If swollen and leaky, then you might try to replace the bad ones with new ones. Visit YOUTUBE for video clips to see if you can do the investigation/repair. Search YOUTUBE using "lcd monitor disassembly" and "lcd monitor repair"!!! Lots ov video clips to learn how to do DIY repair. 12fixlouie

Check connections are good. Check pins in plug. Check with another monitor. Check with another cable.
If all tests are satisfactory then replace faulty monitor. End of life!

nyounger4242, Very common problem!! learn to do flashlight test to evaluate "switch-mode-power-supply" status. Read my FIXYA profile to find out all you need to know about Black, or Black and Blank lcd screen fixes and the options you have. Your monitor NO DIFFERENT than any other CCFL Back-lit LCD monitor in it's basic design and operation!! Good luck with repair. Use warranty if possible. Read, Read, Read, before you do anything!!!! 12fixlouie

Check with cables2go.com. They sell just about all replacement power supplies and any cables you might ever need. Hope this helps.

does your monitor have an external transformer as the psu ?
If so, try disconnecting at mains for about 5 seconds and re-connect. failing that we'll need to dig deeper.
