Dear,

To rectify your problem, Perfrom these steps.
Self-Test Feature Check (STFC) Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

1. Turn off both your computer and monitor.
2. Unplug the video cable from the back of the computer. To ensure proper Self-Test operation, remove both Digital (white connector) and the Analog(blue connector) cables from the back of the computer.
3. Turn on the monitor.
4. 
   

After turning on the projector, press "+" and "-" buttons on the control panel

simultaneously for 3 seconds and release the buttons when screen goes blank.

2 Press "+" and "-" buttons again to exit the diagnostic mode.

3While in Self-diagnostic mode, the screen will run a seven-color-cycle test as

following:

Red--> Green--> Blue--> White--> Watchet Blue--> Dark Green--> Yellow.

Ensure that the colors of the test pattern are correct. Contact Dell if the colors are
not displayed correctly.

its showing u monitor self test feature screen issue either with the monitor cable or monitor or the graphic card

there are buttons on the front, usually 1 and 2. press one for VGA INPUT. that should do it

These are the Tests that should be run to determine which board is bad.You should call a good TV Tech if you are not familiar with this TV.
- The DDP1011 on the DMD board has a feature to display internal test patterns.
- DNle, which is an end port in the digital board, has a feature to display internal test patterns.
- The analog board sends signals to ADV7402 on the digital board.
- The analog board is the first output and the digital board is the second one, followed by DMD, which is the final one.
■ Diagnosis By Module
1. Access Service Mode
(In Standby mode, press "Mute", "1", "8", "2" and "Power" to turn the screen on and enter service mode)
2. Check if there is an error in the DMD board
DDP1011 → TEST PATTERN → Press the right arrow key:
Options of FULL WHITE, BLACK, RED, GREEN and BLUE PATTERN are displayed on the screen.
If "Pattern" does not appear, this is a DMD board error.
3. Check if there is an error in the digital board before the DMD.
When the DMD board has been determined to be error free based on the test patterns:
FACTORY MODE → DNIe → TEST PATTERN normal display: no error in the digital board.
If "Pattern" does not appear, it may be from a DMD board or ATI error or there is an analog board malfunction.
4. Check if there is an error in the analog board.
Check for a power signal from the analog to the digital boards

Check that your monitor is connected properly and tightly to the computer. If it is, then the monitor may be bad. Borrow a friend's monitor and try to see if it works, if someone else's monitor works, then replace your monitor.

Your monitor provides a self-test feature that allows you to check whether your monitor is functioning properly. If your monitor and computer are properly connected but the monitor screen remains dark, run the monitor self-test by performing the following steps:

3. Turn on the monitor.

   The floating 'Dell Self-test Feature Check' dialog box should appear on-screen on a black background if the monitor cannot sense a video signal and is working correctly. While in self-test mode, the power LED remains green. Also, depending upon the selected input, one of the dialogs shown below will continuously scroll through the screen.
   

   1. This box also appears during normal system operation if the video cable becomes disconnected or damaged.

   2. Turn off your monitor and reconnect the video cable, then turn on both your computer and the monitor.

   If your monitor screen remains blank after you use the previous procedure, check your video controller and computer system; your monitor is functioning properly.

Here are a couple things to try.

1. try the input select button on the monitor (The minnus button) without pressing the OSD menu button 1st, see if it changes to analog.

http://support.us.dell.com/support/edocs/monitors/1703fps/en/controls.htm

When the DVI self-test screen is up, it is indicating monitor is in DVI mode.

2. If that doesn't work, try a DVI to analog converter on the DVI port on the monitor and connect the analog cable to the converter. See if you get any video that way.

3. If you can access the On-Screen Display (OSD Menu) perform a factory reset.
