Re: Dell Monitor Repair
These models are prone to shorting of the inverter drive transistors, 2sc5707. An in-circuit ohm meter test will reveal which are shorted if any. They should be replaced in pairs even if only one is shorted. Bad solder joints on the transformer can cause them to short so look for bad solder. Monitor Mike

This is a very common symptom of a failure in the power supply board. These boards have parts called filter capacitors that will begin to have problems after a few years of use. When they start to go out the monitor will have problems powering up or it may have a wavy picture. It is easy to repair the power supply board and get the monitor back up and running. To repair the board you just need to replace the capacitors and it should be as good as new. Here is a link to information on which capacitors need to be replaced. The link shows a Dell 1907FP but they both use the same power supply board so the information will be the same. http://www.ccl-la.com/catalog/product_info.php?cPath=21_29&products_id=236
warc619, Maybe the "button" is only thing broken. Maybe the "switch" is broken. Yoyu will need to see if you can view some video clips of monitor disassembly and repair at YOUTUBE first. Then you will need to "teardown" your unit and determine exactly what component(s) have failed and if you can get new exact same size unit from "Digikey" or "Radio Shack" or "Mouser".... WOW! you may even need to learn how to carefully desolder the bad switch and solder in the new one. Good luck with the repair. You didn't tell us what type of monitor you own!! CRT or CCFL back-lit LCD???? 12fixlouie
The power supply in the unit has died. This is a very common problem with this series of monitor after 2-3 years of use. If you can solder then you should be able to do the repair yourself. Check out our step by step repair guide posted on our site at: www.ccl-la.com Our guide gives parts values and location information as well as how to open the unit up. If you don't feel like doing the repair we also offer repair services, see our web site for details.
I hope this helps, if so please rate our solution.
You have monitor with a very common problem, a dead power supply. After 2-3 years many LCD monitor power supplies will fail just like you have described. The problem is caused by parts called capacitors overheating in the tight space of the monitor case. If you can solder then you should be able to do the repair yourself. We will have a repair guide posted 12/29 after about 5:00 central time that should get you back going again. The repair guide will be on our web site at: www.ccl-la.com If you have any questions please let me know at the address below.

It sounds like you have a monitor with a common problem. After a few years some LCD monitors
will blow a power supply. The problem is caused by parts called
capacitors overheating in the confined space of the monitor. If you are
good at electronics repair/soldering you can usually fix the problem. Check out a few pictures on my web site www.ccl-la.com/badcaps.htm You can take the back cover off your monitor and look for the bad parts,replace any that look like the pictures and your monitor should work
fine. The capacitors do need to be installed with the correct + and -
connections, note the stripe on the old one and insert the new one the
same way. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.

Hi, the issue may with the LCD panel. I work in DELL and have been getting lot of issues like this. It's called vertical line defects.. You can connect and external monitor and press Fn and F8 to toggle the display over to the Monitor. If the display is fine, replace the LCD screen. If the system is under wrranty, call Dell tech support and get a replacement or else call 800-288-4410 (out of warranty repair) department to send your laptop for repair. If the display is the same on the monitor, then the video card/Motherboard has to be replaced.
