If your wires are unhooked, Usually new monitors wires are colour coded , for example, blue to blue, yellow to yellow etc.
If your wires are not colour coded, There is only one way the wires can go, They won't fit just anywhere. If they fit into one connector, then that will be where it needs to go.

Hope this helps

It may have backlights inverter board problem, check the two surface mounted fuses, also can be bad lamps. Also verify that the AC adapter is putting out correct voltage with load.

It is an audio cable with mini stereo phone plug at both ends that you can get it at Radio Shack.<br /> <img src="http://www.fixya.com/uploads/images/DA9418A.jpg" /> <br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial"><a href="http://s807.photobucket.com/home/budm/allalbums">http://s807.photobucket.com/home/budm/allalbums</a></span><br /> <span style="FONT-SIZE: 10pt; FONT-FAMILY: Arial; mso-fareast-font-family: 'Times New Roman'; mso-ansi-language: EN-US; mso-fareast-language: EN-US; mso-bidi-language: AR-SA"><a href="http://en.wikipedia.org/wiki/Capacitor_plague">http://en.wikipedia.org/wiki/Capacitor_plague</a></span>

I assume you mean the power light is flashing? This means that there is aconnection problem or your video card/chip is faulty. Check both of the VGA cable (monitor & PC) are securely connected and there are no bad twists or bends in it, if so replace it. If both ends are secure and cable is o.k. then it is likely that the video card/chip is faulty and needs replacing. Best of luck. Ian.

replace the logic board, not the power supply board. you can find logic board on ebay as low as $29...

sounds like the power supply inside of the monitor is going bad. did you replace the cable from tv to the wall?

This is the best solution for your problem as a 40 year experience with wires etc. Go to the source of your cable signal connector . Open it and clean the terminals with emery paper , sand the end of the cable shiny clean from corrosion , get a new barrel connectors with gold terminals if possible lengthen the ends of the cable , insert and tighten good, use thick rg-16 or rg 40 cable with good insulation ends crimped professionally with a crimpier or buy ready made , not from dollar store. Get a gold plated professional splitter if you need one or two , it will cost about 15 or more each . Make the cable runs as short as possible, using the thick good cables. If needed get a signal magnifier. From radio shack or the source etc. Connect them good and tight . Ground the splitters . Problem solved , you will get crystal clear channel 2 to 7 including 3 and 4 . Isolate the TV cable from other cables and power wires. Vitally

I got hold of an old vga cable (15 pin), cut off the male end. I then cut the existing cable comming out of the monitor. After soldering the wires together and lots of electrical tape wala - it works.

Now the problems I incured - Don't solder wires together based on color, they probably will not match. Peel back the ends of the cut off connectors and find each pin with a Multimeter. Once you find each wires match solder them carefully and tape. When done test and if good place a short splint on the spliced area and tape. This will keep the wires from breaking from movement. Good luck.

The two vx900 s I have here have more of a rectangular plug for the power. Inside it is three large prongs and on the backside should be 3 wires. Two of which go to a smaller plug that connects to the power board.
The power cord is the same as found in many desktop computers.
If this is what you are referring to. Then the plug should be connected inside and it snaps into place onto the meatl part inside the monitor.
You may have to disassemble the unit to get it back together.
Sorry for delay in reply, I never was notified that you had replied.

Problem solved! The main power thingy (the thing with the big red wire coming out of it) was all black and dusty. There was 'soot' all over the whole insides of the monitor. I concluded that this monitor should be laid to rest, and a new flat-screen monitor erected in its place.
