Question about Computers & Internet
SOURCE: won't turn on
My monitor died and wouldn't turn on. Found 3-4 of the electrolytic capacitors had bulging tops and a dead short across them. Removed the caps but the short remained. Found the mbr10100 to220 packaged dual diode rectifier had a short across one side. Replaced the capacitors with Pansonic 10,000 hour
units and the 10 amp mbr10100 with a mbr20150 20 amp rectifier which brought the monitor back to normal operation.

The vga cable is a DB15, 3 ranks with male connector at each end,
(you can use a vga extention and add a little male to male adaptor at the female end to get finaly 2 males connectors)
And, the power cord is in fact an ac/dc adaptor, the replacement part is: 12b27-0428 (12v 5A 60w 4 pins) ...
just type de number 12b27-0428 on internet and you're on ...

The clicking is a sure sign of a bad power supply. Go to our web site and check out the pictures of what blown capacitors look like, www.ccl-la.com/badcaps.htm Now open the back of your monitor again and look at the power supply board. Check the capacitors, the tops should be flat if hey have any bulging at all then they will need to be replaced. If any are damaged then replace them all because the rest will soon pop too. Be sure to use high temp replacements that will be marked 105c. Do not use caps from Radio Shack they are only rated for general purpose not high frequency use. You can order the correct ones from several places on the internet or we can supply them for you. The values you will need to get are going to be marked on the sides of the ones coming out but will be like 220uf, 470uf 1000uf etc. and have a voltage rating. When you insert the new caps in the board be sure to have the polarity stripe going the same direction as the old one goes. If you have any more questions just let me know.
I hope this helps, If so please rate our solution.

Have you turned your power settings down so far that the monitor has no time to produce an image, before it shuts itself down?
That setting is usually on the same page or tab as the Screen Saver settings are. If you set your monitor to save power so much that it will turn itself off in a very short time, you will see this kind of behavior.
Try to get to that tab again, and give your monitor more time to be "awake" for you. Right-click on a blank area of the monitor, then choose properties, and Screen Saver, and go from there.
Also, ensure your cables are plugged into the right jack on the back of your computer. The monitor plug/jack is very similar to a serial jack, and you can ruin your monitor by getting these wrong.
