    Hi tantong, I don't think that any lamp is broken becuase while i'm pushin the power bottom every thing are displayed well as they were displayed before this problem arose.

    If I don't push the bottom it is completely off and i can't see anything.

    What is inverter board?
    Thanks a lot

Hi this is the way how to examine what's wrong with your LCD monitors. After you turned it on and the screen blacked out, you have to check that if you can see the image on the screen or not by shining a flashlight into the screen, not directly but find the best angle to the screen and take a look very closely. If you can see the icons or any image, there will be a minor problem. This is because of the lamps inside screen. Some of them were broken and it is very easy to replace. If you cannot see anything on the screen, there'll be some problems with inverter board. Hope this help!! If anything I can help you with, feel free to let me know.
Thank you,

Hi atieh, How long does your monitor stay on after you push the screen-power button? And after it turned off by itself, you go check the image on screen without pushing any button by using my method above (USING FLASHLIGHT). The inverter board is the circuit board inside the monitor. This board controls monitor power, signal input and output from VGA card. If there is something wrong with CCFL lamps, it will shut down by itself because of circuit safety. As I mentioned last time, it is not too difficult to change the lamps. Could you tell me the specification or data sheet of your monitor?
Thank you,
Tantong

Aux power led light is amber on dimension E521


I think your problem is your memory or video card.

Below are some steps that I recommend.

When you plug in the power cord is there any lights whatsoever on the computer?

When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.

Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).

Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.

Maybe you have a Static Charge Buildup. Remove the Power Cord, then Press and Hold the power button for 30 seconds. After 30 seconds plug the power cord back in and hit the power button to see if it boots.

Maybe your memory is bad or the memory slot is bad.

Remove the Power Cord, Open the Case and remove one of the memory chips. Set the chip aside then try rebooting the computer. If it boots, then you know the memory chip you set aside is bad so mark an x on it with an ink pen. If it fails to boot then move the chip to the next memory slot and try rebooting. If it fails take the chip out and set it aside, then put the other chip in and try booting it in both slots. If it boots, just to verify that the chip set aside is bad, mark an x on it and put it into the open memory chip slot and try booting.

Maybe your power supply is bad. Sometimes there is enough power to make the power light or some other lights come on but not enough power to make the fan turn on or hard drive spin.


Below are links and info I found from Dell's Website based on your model.

Dell 4500 won't turn on,power light amber/green


Is the light more amber or more green? If you push the button and it goes amber, then you probably have a bad power supply. Try getting another power supply to test. If that doesn't solve the problem, then you probably have a bad motherboard.

Its not booting and the Leds VRM and NMI are with amber color


VRM and NMI lights lit usually indicate an issue with CPU #2's VRM which can be replaced. Also check 5 lights on back middle of system. If VRM light is lit here remove CPU 2 and VRM and reboot system. If system boots, this was the issue...

Computer Won't Power Up


If the blinking amber LED is on the computer itself and not the monitor, this is most likely a power supply issue. First thing to try would be replace the power supply. If the blinking led is on the monitor, it probably has bad capacitors and needs to be replaced. (or repaired)

Stuck in power saver


Try the unlock procedure: With the monitor on press and hold the "MENU button for abot five seconds and see if it resets. If that doesn't work tell me a bit more about the screen - is there any OSD (on screen display) or error messages? Is the power indicator light on? If so, what color is it? Blue indicates that that you may need to turn the brightness and contrast up...\ If it is actually in power save the indicator light will be amber. What color is it? If the light is amber and all the connections to the computer are correct and it still won't come-up then it's an internal problem and the protect circuit may be keeping the screen from lighting. Good luck... And let me know. Bill
