dell 1504fp no input signal

[smd]

I have a dell 1504fp monitor. Once I connect it to a computer and power it on it displays the normal Dell welcome screen message but there is no input signal from the computer. What could be wrong with it? Which components do I check?

Just a little more information please!
When you have the monitor turned with a signal applied what is the power LED doing?
Dose it indicate a signal?
Can you turn the monitor on and off with the front power switch?
We really need to see some pictures of what you're working on.

With a signal applied I turn on the monitor. The power on LED is orange, it then turns green and instead of displaying the input from the computer it displays the normal Dell RGB message.

Try a different VGA cable,If that doesn't work hook up to a different computer.
Also Make sure you have the correct resolution selected.

I found a FET the MTP2955V FET had a dry joint. I resoldered it and lowered the resolution on my PC, the monitor now works fine. I was using a resolution of 1280 by 1024 the 15" screen will only take 1024 by 768.
