Okay we need help here. We bought this computer used and we know the monitor worked when we were looking at it. Brought it home and nothing, no picture, no green light to show the monitor is on. Connection are correct and tighten. Any suggestions? Pls help

call ibuypower technical support. if you brought it from them
if it's under warranty call the company you brought it from.
if you try to fix it yourself, the may not take it back. and keep your money.
that being said make sure your monitor is plug in the right port from the picture I saw on newegg, they have two ports that it can plug into a blue vga port or a white dvi. you want to plug into the one on video card.
Are you asking about this LCD Daewoo (F227B) monitor? LCD monitors do not use Vertical/Horizontal IC like the CRT type for the H/V Yoke.
What is the problem with the monitor?
Common problem with LCD monitor: Most common failures in the LCD monitors are bad capacitors (bulging top/seal or leaking) in the power supply, blown fuses, failed inverter circuits (blown fuse, shorted transistors, shorted/open transformers), bad lamps (poor solder connections or worn out lamps). You will need to open it up and inspect the inside, see example of failed monitors to get some ideas what to look for: http://s807.photobucket.com/home/budm/allalbums Post back what you see inside so we can guide you further and it will help out other people in the future also. http://en.wikipedia.org/wiki/Capacitor_plague http://www.badcaps.net
Make sure you have connected into the correct video port. DVI should be used for LCD monitors and VGA should be used for CRT monitors. Since both ports look the same people often get confused. Try it and let me know.
Maybe they put more volts on it, because of the cable length. About putting the manual on Fixya. I do not know how you would do that. I know that you can have a little more volts and be okay but not enough is bad. Are you sure it is the correct cord?
You need to get your computer in the correct resolution and refresh rate to make the monitor work. It looks like the correct numbers for your monitor are:
Resolution: 1024x768 pixels Refresh Rate: 60 hz
You can change these settings in the display tab or display properties (In XP - right click desktop, click properties, under settings tab adjust resolution and then click advanced, the monitor tab, and make sure refresh rate is set to 60 hz)
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.
