It can be bad solder joints, shorted transistors, bad fuse in the inverter circuits, bad caps, worst case will be the lamp assemblies.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/albums/yy352/budm/ Post back what you see inside so we can guide you further and it will help out other people in the future also.

Check the cable (VGA cable) to the computer and see that it is fully secure and that on the cable male end, there are no bent, broken or damaged pins. Check the end that fits into the monitor and look for the same, bent pins mean that the signal is not getting through and this will result in a problem such as you describe.

Try also changing the VGA lead and seeing if that helps, also test the monitor on another computer.

If that fails, the monitor is probably ready for replacing or at least a check to see if it can be repaired

Ity sounds like it has bad connection at the T-CON board on the back of the monitor.

http://s807.photobucket.com/albums/yy352/budm/DELL/Dell%202408WFP%20Rev%20A02/

That will be the first place to check. Check the DC voltage on the surface mounted fuse on the T-CON board.

There are more than two versions of this model.
As you can see in my pictures, it may have bad solder joints, transistors, capacitors. Those are the things you need to check if you are going to DIY repair.
You should also read my guides to understand how LCD monitor works.

Try to reconnect all cable of your pc then your ram then bring it back make it sure it is set up ..then then try to turn it on or wait for 30minutes

Hi,

Welcome to Fixya. Indeed this is a problem with the monitor. You have an option to fix it by yourself if you have knowledge with electronics or you can have it fix by a trained professional. The problem can be a problem with the hardware part of the monitor it can be a fuse, capacitor, transistor or any part of the mainboard of the monitor. I've provided a service manual for your E173FP so that incase you want to fix it by yourself.

E173FP Service Manual

If you have questions please let me know. Thanks for using Fixya.

Most Dell LCDs have multiple inputs and they will go into "standby" while waiting for a signal from your PC. This happens when your PC goes into "sleep" mode or if you are sure your PC is not in "sleep" mode then usually the LCD is not in the correct input selection. Check the input selection for the appropriate input. As always, make sure the cables are securely connected. Hope this helps.

* check cable connection
* check settings of the monitor (select/menu button on the monitor) in the On Screen Display.
* if everything is set up OK get in contact with the supplier

More likely to have shorted out transistors, also need to check the fuse as shown in the pictures:

Also inpsect the solder joints and caps.

Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply (they should be replaced in a set), blown fuses; poor solder joints, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps).

See my tip here: http://www.fixya.com/support/r9423506-flickering_lcd_crt_monitor_screen_or

The blinking LED mean that the display will not be shown to you and this problem belongs to short circuiting of transistor that are being connected with the mini transformers. The transformers boosts up the voltages for the LCD screen.
IF you are a technical person then handle the situation as i am going to describe. Otherwise, get it done by an expert in this field.

1. Open the back stand that holds the monitor by opening the 4 nos. of philip screws behind it as shown

2.After the stand is removed you will need to pry the back of the case off as illustrated in the pictures below. Use a small flat bladed screwdriver start at one of the release openings on the bottom as shown. Once you have a little gap in the case just pull the 2 halves apart and work your way around the screen.


3.
After the screen unit is removed from the plastic case we can get down to the repair. We need to remove the power supply unit. You will need to unplug the 4 back-light connections (connectors with pink and white leads, circled in red) and the control panel cable the flat signal cable. Then remove the 2 screws from each end, then undo the 2 small nuts holding the vga connector to the case (circled in yellow).

4.
Before you fully remove the shield and board assembly be sure to unplug the LCD signal cable that is under the boards as seen in the picture to the right. Now turn the assembly over and remove the 5 screws and the 2 plastic standoff clips as marked by the yellow circles below. Now with the board removed you will need to replaced the components that are circled. The parts are as follows:
3 Amp Fuse (yellow)
Q759, Q760, Q734 & Q740 - C5707 transistors (red)
Q743 & Q751 - MOSFET Transistors (blue)
The location number are for a E173FPb but the E172FPb boards have the components in the same locations.






I hope it is an understandable thing to do. Get it done yourself or an expert and get back your view...

good luck

Sounds like the adjust and menu buttons on you monitor are faulty. To fix you will need to remove the bezel and check the switches on the little keypad.

no signal coming from the cpu just fix the vga cable at the back or if you have a vido card put it in their not on the onboard video output

if your LCD is still under warranty, call dell technical support so that they can replace your LCD panel

First check your monitor light is blinking or not. If it is then--

Check your monitor cable which is connected your CPU. If it is ok then
Open your CPU and unplug *********** board power cable and re-install it.
And also remove RAM and clean with a brush softly and re-install it.

Best of Luck

Look for shorted transistors (c5707) in the power supply/inverter board.
