Dell Monitor Repair

Hello,
If this works it would be awesome. Sadly, when I searched and called digikey they need more information about this part. Can you provide more detail about the capacitor?

Thanks!

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.

Hi there, this is a late reply, sorry, but you just need an electrolytic capacitor. Any voltage above 16V should do, but try to make sure you get the right capacitance...

Good luck.

Monitor will not stay on


Hello,

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.

Hello,

You have a failure of the power supply board. The problem is caused by parts called capacitors that have shorted and this causes the backlight circuit to stop working. Here is a link to a page that show how to repair the power supply board and get the monitor back going again.

Power button not working. Stuck in on position. How do I replace it?


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

My viewsonic va1912wb just flat-out died. Won't turn on, no lights, no response. Is there a likely cause, and is there anything user-repairable?


Hello,

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.

Hello,

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 he monitor. If you are good at electronics repair/soldering you can usually fix he 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 have repair questions email me. If you don't want to try the repair yourself we offer a repair service for $35 plus shipping.
