Fixing VGA Connector
A broken VGA connector could cause no display, color out, intermittent problem and etc. Looking at the connector we thought it could be an easy job to replace with a new VGA connector. If you have experience in changing the connector, it could only takes you about 10 to 15 minutes job but if you are just starting out you might need more than an hour or two to do the job. I found that the best to replace the connector is to first cut off the original VGA connector and take out all the wires inside. They have colors representing different signal. Normally red wire would be red signal and red ground, green wire for green signal and green ground and blue wire for blue signal and blue ground. The horizontal and vertical signal can be in any colors and you need to test it out using ohmmeter. Once you know all the important signal colors your next step is to use a wise to clamp on the new VGA connector. Put a little bit solder on each pin and then finally you can solder back the signal wires accordingly. If you need the schematic you can always visit this website for the signal parameters.
