Possible power supply (http://www.lcdrepair.us/2405fp-power.html) failure due to bad caps (leaking/bulging tops) and not supplying power to the inverter bd (http://www.lcdrepair.us/2405fp-inverter.html)

Worst case will be lamp assemblies failure. It will expensive gambling to DIY repair unless you have Inverter tester and lamp tester to verify which assemblies went out..

Have emachines monitor which is not coming on power button fast flicker


Which power button is flickering (your computer, or your monitor).
Here's some tricks I would try...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your display on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

I have a dell studio 540 desktop, I need to restore to factory settings but my monitor will not stay open. It opens for a few seconds then immediately goes into power saver mode and turns off, how can


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.

Please post back in a Comment.

My acer monitor come on and screen go blank


Step 1:
WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Causes a Computer Monitor to Go Blank b> While a blank screen may be caused by a general power outage, more often it's a problem with the screen itself. It could be a loose video or power cable going to the monitor. If that's the case, you can get the screen working again and be back in business in a few minutes. b> Power Problems All the power might be off due to a bad outlet, switch, fuse, or circuit breaker. If you hear no sound coming from the computer and its power light is off, check the power connection and breaker or fuse. Video Cable Many times the cause of monitor blackouts is a loose video cable connection. This might happen if you move the monitor or the cable. The video cable runs from the back of the computer to the monitor. It has a multi-pin connector on each end and both of them screw down securely. If the screws aren't tight, either connector could become loose. If that happens, the video signal could stop suddenly and make the picture go blank. Check both ends of the connector to make sure they're firmly seated and the screws are tight. The cable itself might be bad.This is unlikely, but possible. b> Display Power The monitor must have power. If the power light isn't lit on the monitor, it may have been turned off or become unplugged. Press the power button to make sure it wasn't accidentally turned off. Make sure the monitor is plugged in. If it's connected to a power strip, check that the power strip is on. If that checks out, unplug the monitor and try a different outlet. Power strip sockets can sometimes fail. Flat-screen monitors may have a power-brick-style adapter. It, too, has connectors. Follow the power cable from the monitor's power plug back to the monitor. About halfway up you'll find a thick rectangular plastic brick. The power goes into a modular-style equipment socket. This can become loose. Follow the wire the rest of the way to the monitor. It connects to the back of the screen with a small round plug. Check that it's firmly plugged in. If everything's plugged in right and the power light on the monitor's still off, the power brick might be bad. b> Video Card Some computers have a separate video card inside. It may come loose and cause a blank screen. If this is the case, open the computer and inspect the video card. Sometimes removing and reseating the card will fix the problem. If it has to be replaced, most video cards are not expensive.

If its a flat screen monitor ?

eMachines flat-screen monitors offer high quality at low cost. eMachines flat-screen monitors are compatible with most brands of PCs. Issues with eMachines flat-screen monitors can arise from faulty power sources, cable problems and incompatible settings. These issues can be resolved by testing step-by-step each possible cause.

Check the LEDs on the front of the computer case to confirm that the computer receives power. Plug the eMachines monitor's power cable into a working AC outlet. Press the monitor's power button. Check the LEDs on the front bezel or power button of the eMachines monitor to confirm that the monitor receives power. Orange or blinking LEDs indicate low power or no signal. Green LEDs denote a working connection.. Perform a monitor self-test. Switch off the monitor. Unplug the video cable from the monitor. Press the eMachines monitor's power button. An eMachines logo, Windows logo or "no signal" message indicates that the monitor is working properly. Plug the eMachines monitor's video cable into the video port on the computer. Attach the monitor's included DVI-to-VGA adapter to the monitor's VGA cable if your computer has a DVI port (15 or 25 pin-slots with 1 side slot) in place of a VGA port (15 pin-slots, no side slot). Press the eMachines monitor's input button to change the monitor's setting to match the computer port used. Set your monitor to DVI if connected to your computer's DVI port. Set your monitor to VGA if connected to your computer's VGA port. Connect the eMachines monitor to a known working computer with a known working video cable if the problem persists. Contact Gateway, eMachines manufacturer, if the monitor issue is not resolved. Hope this helps.

Check video cable on computer


On the monitor unplug the power and video cable. Plug the power cable in, and then the monitor cable. Power off your computer, then turn on the monitor. After you power on the monitor, turn the computer on.
