monitor cable problem

I posted here before about a weird color display on my monitor. I found out that it is the cables problem. When I twist it a certain way, the image is normal. But once I release the cable, the colors are off. Does anyone know where I can bring my monitor to get fixed? My warranty on this monitor expired about a year ago from micronpc. I bought it at Best Buy and they don't even carry this model anymore. Thanks

Are you interested in fixing it yourself?

Sure, I would try to fix it if I knew how. It's attached to the monitor so I would have to open it to fix it and I'm scared. If you know how could you tell me? Thanks

Well, I don't want to get you into trouble, so maybe it is best if you have it repaired by a technician. You would need to have soldering skills, and the equipment of course. Which end of the cable were you twisting when the picture got better, was it at the monitor end or the other end that connects to your computer? If it is at the computer it would be helpful to determine if it's the cable, or possibly the connection in the video port. A heavy dangling cord can sometimes break the solder joints loose on the video card, meaning that it is possible your twisting of the cable is actually causing a connection to make on the video card. You would need to experiment some more and try to determine. The same thing can happen at the monitor, especially if the video cable is removeable from the back of the monitor. I think it would tend to happen less frequently at this end if the cable is not removable from the monitor.

When I twist the cable right at the monitor, it's fine. I know this for a fact because I have to twist it really hard. I think i loosened it a lot. Well I opened up the monitor and the end of the cable is connected directly to a PCB. I'm trying to find a replacement VGA cable for this, but all I see are extension VGA cables. I e-mailed the manufacturer (Micronpc) and now I'm waiting for a response. Thanks Art, for your responses and help.

Ok, The point I was wanting to get across was that twisting the cable can sometimes make or break weak solder joints at the board. The trick is determining if your twisting is making a connection within the cable itself, or at the circuit board connections. Often times it is only a matter of applying a hot soldering iron to the solder joints at the board, and the problem is fixed. It takes a keen eye. If you are certain the problem is in the cable then you can buy a cable with connectors at each end, if that is the easiest/cheapest option, and cut off one of the ends. Your biggest task will be to solder the wires to the board in the correct fashion.
Now, for the best news of all... If the problem is near one end of the cable, then simply shorten this same cable by cutting off the "bad" section. This will shorten the cable by a foot or two, but it may still be plenty long enough. Best of all is that you can be sure of what color wire needs to be soldered in every location by using the short piece as your guide! good luck

Thanks for your quick response, Art. The bad sector of the cable is right at the back of the monitor. I don't think I would want to solder anything to the PCB. The end of the cable that connects to the monitor has a white molex that plugs into the PCB. I think it would be much easier for me to change that then soldering. I hope Micronpc doesn't charge $50 just for a cable otherwise, I'm going to heed your advice and cut and solder the cable. Well, thanks alot.
