How To Repair Static in Headphone Port?
Hi. I'm working on a MacBook Pro Core 2 Duo Model 2.33 GHz 15" laptop. There is a lot of crunchy static coming out of the headphone port when I attach a 1/8 stereo cable to run it through 2 Boss powered monitors. I have to turn and twist the cable in the port to eliminate the static and make sure sound is coming from L/R channels. I tried 3 different cables to make sure it wasn't a bad cable, but the problem occurs the same from each cable.
Is it safe to spray a contact cleaner through the port and see if that corrects the distortion issue? Do these ports/jacks normally have to be replaced rather than repaired?
Thanks for any help and advice.
