Replacing a monitor's vga connector (the cable's end) ?

[KrakenHelper]

Hello everyone ,

since 2012 i bought a new monitor for my computer , but after some trouble of chaging my graphic card the monitor cable no longer works bcs i plugged it in and off lots of times , sometimes if i move it left and right i can get a yellow or a red screen (it's very hard to get if my hand loose the cable the screen disappears) , the thing i want to do is to cut off the damaged part and replace it by another vga connector , i'll use my old monitor vga cable to cut it's end (my old monitor doesn't works "internal damage") and solder every wire according to the colors , what i'm afraid of is getting some different colors , solution : a friend suggest me to use an ohm-meter to Solder each wire to the correct one , here's my problem , i don't know how to use my multimeter(set at ohm detection) to measure the resistance of each wire , and i'm wondering what to do if i get the same resistance at some different wires.

I need your help , i'll appreciate every replie and thanks for help 😉


PS : here's a pic containing my plan to fix the cable , it will help you to understand the problem

I think your friend meant to use the multimeter to check it from the plugs, so each wire/pin on the plug connects to the corresponding wire/pin at the other end. Basically you should get very low ohm reading (and a beep) from the wires/pins that connect to each other and very high reading to anything else.

Distorted colors while wiggling the VGA cord is normal. Make sure it's plugged in all the way and use the thumbscrews to keep it in position. If the VGA cord is damaged, just buy a new one, they're like $5 at local electronic stores. And if you have a working VGA cable that is going to be used to fix the broken one, why not just that one instead?

Kari : I didn't understand this solution ,if i buy another connector ( the thing with pins ) instead of an entire cable how can i use the multimeter to accord each wire to it's pin , i've found some pics for the vga pinout but they rae different

modernwar99 : i can't plugg the other vga cable bcs the damaged is soldred from the inside it can't be blugged off

oh right, both cables are hardwired to the monitors that will complicate things...hmm i dont think you can use the multimeter to measure towards the monitors end and since the 'to-be-replaced' plug is somewhat broken measuring it might give irrational results as well... You might need to cut open the broken plug so much that you can see which pins the wires connect to and then use the multimeter to find out the corresponding wire coming from the donor plug, but if there are multiple wires with the same color coding in the broken cable I dont know how you could determine which is which...

Well , cutting the damaged cable ends to discover the correct pin to each wire is a perfect idea i'll try it thanks for this , but if you saw the image on this link : http://postimg.org/image/e7n19q5yh/ , you'll notice that i'll cut off the entire damaged part of the broken cable and cut the same part from the new cable before measuring , then i will solder the wires , check the pic i'll measure exactly at "soldering wires" sequence , let me know if this is a bad maneuver before trying to open the connector.
