SOURCE: Green Power LED is lit- But no image on the screen

Hi, I have just repaired one of these with the same problem. Turned out to be a 680uf 25v capacitor that had failed. Capacitor was visibly domed. Easy repair with new capacitor. Hope this helps.

SOURCE: syncmaster 225ms LCD monitor is blank

Hello,
It sounds like you have a monitor with a common problem. After a few years some LCD monitorswill blow a power supply. The problem is caused by parts calledcapacitors overheating in the confined space of he monitor. If you aregood at electronics repair/soldering you can usually fix he problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htmYou can take the back cover off your monitor and look for the badparts, replace any that look like the pictues 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 arepair service for $35 plus shipping. I hope this helps, if so pleaserate my solution.

I have a Pelco PMCL542A 42" monitor that power RED led is on but screen is black


Lcd tv's Do that when the backlight bulb is out. There should be a small panel on the back. Order a new bulb and replace it and it should work fine.

What is the best brand of monitor without lot of problem like black screen orange stand by light?


Any known brand, such as Samsung, Dell, Acer etc.

The main thing with monitors these days is to choose one that is LED back lit. LCD's use inverters that are very power hungry and they tend to burn out capacitors after a couple of years of use.

LED how ever are very low energy and don't need an inverter circuit to power the LED's, thus MUCH better life time.

Screen stays black but lit when shut down


If the monitor led is indicating stand by and it seems as if the monitor is still on, could be a sign of an aging monitor. As long as the led changes along with the function of the monitor there's really no way to indicate the monitor still on after shut down especially when the led is amber telling you it's on standby mode.

My Samsung SyncMaster 740N occasionally turns itself off. Timing varies and the condition varies. Usually the screen just goes black - from seconds to hours after it is turned on - the blue LED remains...


This could be because of the 'eco' friendliness of the monitor. Basically a lot of monitors are designed to turn off into a low power state when not in use so to preserve power and life of the monitor. I would return the monitor as the sensors that control this seem to be broken in your monitor.

I have the VE278Q which is connected by display port, every time i turn off my computer and then turn it back on the monitor can't be found, I have to unplug the display port cable, unplug the monitor,...


when you say monitor can't be found did you mean the monitor has no reactions when you turn on your pc?

here are some test you may need to do to know which part is faulty
1. Turn on your computer, did it display the monitor's logo on screen? When it does monitor is good, when only blank screen it could be the vga cable or the video card.
2. See if the led indication lit. When it lit to steady green, it's good signal is coming in from the video card. It should be followed by screen display. If no display it could be the backlight inverter lamp busted or faulty inverter board. When lit green then turns red, no signal coming from the video card. Check vga cable if fix properly to both monitor and video card. Or may need to reseat properly connection of video card from the motherboard. If no led indication lamp, then monitor is dead. Check ac power cord for continuity using multitester. Check power supply section in the monitor, replaced bulged or blown capacitor with exact value, this components were the first to get affected when lcd monitor failed o turn on.
3. When computer was turned on got display and then monitor turns black, go check the vga cable, Fix the connection properly or may need to replace it with new one.
4. When no signal appears or display blank screen after logo, then check video card. First remedy is to disconnect it the reseat properly to the motherboard. If this have no effect change your video card.

go follow these steps and let me know which is closely to your problem so I can give you a good advise.

How do I turn it on


Hello.

To power on the Gateway VX750, press the power button on the front. The power button has 3 sides with a "G" in the middle.

The LED indicates the power status of the monitor.
  • Not lit - The monitor is turned off or does not have power connected.
  • Blinks one time and then goes off - The LED blinks one time when the monitor's power cord is plugged into an AC outlet to indicate that power is detected.
  • Lit solid blue - The monitor is turned on and active.
  • Blinking blue - The monitor is in power saving mode. Before entering power saving mode, a message briefly appears.
Hope this helps.

Black Screen on the monitor


did you drop or hit the laptop recently?
Try using a flashlight. If you can see the images in the screen, the light behind the LED screen is burnt. If you can't, try attaching a full size external computer monitor and see if it works. If it doesn't, then you may have a bigger problem than just your screen
