I need a power cable for an LM720a monitor - AOC LM 720 17" Flat Panel LCD Monitor

1. Check the power cable: Make sure the power cable is properly connected to the monitor and to the power source.
2. Check the video cable: Make sure the video cable is properly connected to the computer and to the monitor.
3. Check the computer settings: Make sure the computer is set to the correct display settings for the monitor. You can typically do this by right-clicking on the desktop and selecting "Display settings."
4. Check the power source: Make sure the power source is working and that there is no problem with the outlet or power cord.
5. Check the power button: Make sure the power button on the right side of the monitor is not stuck and is functioning properly.
6. Try a different cable or computer: If possible, try connecting the monitor to a different computer or cable to see if the issue is with the computer or cable.

If none of these steps resolve the issue, it may be a problem with the monitor itself

Is this an external monitor cable? Where the monitor cable that connects to the computer has two USB cables attached at one end?

If so, no. You do not need to plug both ends in. If one is powering the monitor fine and you see no performance problem occurring with the monitor you are OK to plug in just one.

The extra USB end connected to the cable is for additional power supply. If for some reason the machine you are plugging into does not supply enough power to the external monitor you would plug the second end it to the machine and boost the power to the monitor.

Hope that helps.

l have a computer monitor l need a cable for power supply the is it moDer E210250054

I see two things here, but need clarification;

1) Monitor goes to Power Saver Mode, then turns -> OFF?

Sure that monitor didn't go into Standby Mode?

2) Why are you performing a restore back to factory settings?
Pick up a virus?

Primer;
The monitor receives a signal. A video signal. The video signal comes from the computer.

If the monitor is NOT receiving a video signal, then the monitor will state No Signal.
This is for older monitors.

New monitors do not state No Signal anymore.
It's Power Saver Mode, or Sleep Mode.

If the monitor is truly OFF, the Power On button will Not be lit up.
Or the Power On LED light on the monitor.

Monitor power on LED is lit, or Power On button is lit?

Monitor is not receiving a video signal;

Use a monitor cable from a KNOWN to be working monitor, for a temporary test.
OR,
Use a Known to be working monitor, and it's monitor cable.

Need to find out if monitor cable is good.

Monitor cable checks out good?

Then problem is computer.

The two leading issues with desktop computer failure, is;

1) Computer is dirty inside
2) Power Supply inside computer is bad.

if u are changing ur old monitor to new u may face problem ,

press F8 when the system starts and select the safe mode option and login admin mode change video settings resolution(control panel/display properties) into higer like (1020 pix) and if it visible give yes and restart

anthony_salt, If the fuse you replaced is still good, then I would first check the "switch-mode-power-supply" for bad electrolytic filter capacitors. By the way, was the original fuse bad? I also highly recommend you pay a visit to YOUTUBE, search out and view the longer vid clips of lcd monitor disassembly and lcd monitor repair. FYI try a website run by another fixya guy nickname is "buddymc" and the site is www.ccl-la.com/badcaps.htm They refurbish (rebuild) lcd displays of all kinds and all manufacturers. You can also check out these other sites FYI. www.lcdparts.net , www.badcaps.net I hope that this info steers you in correct direction. Good luck guy. 12fixlouie bye

the vga cable u have to buy it from computer/monitor shop..
ask them for cable by telling them the model and spec. of your monitor.

Hi Kiran,
If the power cable matches the power cable of your computer, it's a standard 3 prong power cable and you don't need a specific kind. If it's a small circular type you will need an external AC adapter, the type will depend on the manufacturer and make of your monitor. These can be found on eBay usually. Most monitors use different types of stands, but if your monitor has the standard VESA 75 or 100mm mounting holes on the back, you can find many monitor stands that are compatible with it. The standard VESA mounting holes are usually used for wall mounts but lots of stands connect to the monitor this way. You can tell by a set of 4 holes for screws or bolts on the back that are either 75mm or 100mm apart (vertically and horizontally). Don't forget to get the right kind of bolts for the stand, if it doesn't include them.

try to resolder all lost contact on flyback transformer..............................

Try to connect another monitor to verify the problem is related with your video card or the monitor itself
