Re: i want to become a motherboard analizer
Sounds like an inverter problem. If the power supply is internal replace the capacitors coming out of the voltage regulators. These are usually 1000mf and/or 470mf. If that doesn't do the trick look up the numbers on the 8-pin chips that drive the secondary transformers on the inverter to see if they are getting the right voltages. Good Luck!

You MUST calibrate the BEFORE use..
See the user guide . 'stride length'
If the initial settings are not correct, the measurement results may not be accurate

You must set it to miles instead of Kilometres. See manual
These units are known for having issues with the internal power supply board. There are parts called capacitors that fail due to heat buildup in the monitor case. When they die the power supply stops working and you get a dead monitor just like you have. If you can solder then you should be able to repair your unit. We have a free step by step repair guide posted on our web site at: http://www.ccl-la.com/blog/index.php/dell-e172fpc-e173fpc-repair/ The repair should take less than 20 minutes to do and cost less than $15 for parts.
I hope this helps, if so please rate our solution.
Check our web site at: www.ccl-la.com We have repair and disassembly guides for many Dell and other brands of LCD monitors. We don't have that exact model Dell but the others should give you an idea on how to open your. We have pictures, step by step repair guides, etc.

If the screen is completely black, your screen may indeed be dead. There are a few solutions you can try before throwing in the towel though.
1) Test the monitor on another PC if you can. 2) Make sure the contrast, and brightness aren't turned all the way down. 3) Make sure the graphics card in your PC is functional. You can easily test this by connecting a known working monitor to your computer.
If these steps do not resolve the issue, and your graphics card is in good working order, you indeed have a dead monitor on your hands. It may be cheaper to buy a new monitor, than to have that one serviced.
Your actually thinking about it the wrong way.
Replacing the screen in LCD's is more expensive then replacing the monitor. Stupid I know, but that is how they ensure you have to keep upgrading. Same thing applies to a laptop motherboard for the same reason.
You do still have one small light at the end of the tunnel though.
Check around on eBay or similar and you maybe able to find a complete monitor with a dead power board that you can salvage the screen from. Do a search for words like Faulty, broiken, not working in the computer section.
May I suggest working on the monitor itself before tackling the video card.
To my understanding, your monitor came with an installation CD that contain drivers/software for your OS to recognize the LCD correctly. Should you need a downloadable copy, its filename is 20050615115516359_SM740N.exe.
If you have already installed the monitor's drivers and updated your video card's driver as well, and problem persist, you may need to work on the AGP or PCI-E of the motherboard itself. Pls post back motherboard or PC's brand and model.
Hope this be of help. Pls post back as requested, how things turned up or should you need additional information.
Usually, this is due to a bad connection on one or more of the wires in the monitor data cable. Either the pins aren't making a good connection to the port on your computer, or there's a short in the cable somewhere.
If hitting the monitor solves it, it's probably a bad connection between the cable and the monitor, where the wires are soldered into place. If this is the case, I would suggest against trying to repair it. CRT monitors store large amounts of electricity, and a discharge while you are working on it can be deadly. Never open up a monitor case.
Try wiggling the connection on the back of the computer next time and see if that fixes it. If it does, remove the cable and check for any loose pins, or bent pins. If there are any, the cable could be repaired, though 15" CRT monitors are so cheap you're probably better off replacing it. Look on craigslist.org for your city. If it has a cite for your city, it's likely you can get a cheap used monitor there.
