Question about Daewoo 17N5 17 in.CRT Conventional Monitor
SOURCE: No power in my Daewoo Monitor
Hi, Youo have zeroed in on the problem area. It looks like a power supply problem. More often than not, there is a fuse inside. If you would venture to open the unit up, do a visual check on the fuse. If it is busted: 1. Clean - no burnt/scorching/black marks inside the glass tube, then you can simply replace and hopefully the unit will be operational; 2. Dark smudges - or small burnt metal pellets inside the glass tube, then it is possible that you have other defective components that caused the fuse to blow. Normal components that are known to go bad are the big capacitor and or the power transistor regulator. Most current designs uses a switch mode power supply where your mains AC voltage is converted to DC that powers a circuit that eventually produces a lower DC voltage say 12VDC for use of the monitor. Should you venture a DIY (do-it-yourself), pls remember safety precautions when working with powered electronics. Hope this be of some help/idea. Post back how things are or should you need further information. Good luck and kind regards.

Open it up and check for bad caps in the power supply first, post back what you see so we can guide you further, see example of failed monitors due to bad caps: http://s807.photobucket.com/home/budm/allalbums
