Loose power jack

My AC Adapter Connector (where the AC cord plugs into the computer) is loose and causes the screen to pulse, as if between battery source and AC source. I just got the Jack replaced in Dec, because it burned out. it was still loose after that and before I bought it in. I have to play around with it and pull the plug to the side so it makes connection. It doesn't make connection when the plug is in straight. Can it be fixed?

Hello,

You are describing the symptoms of a loose power jack. Whoever repaired it did not do a good job. There are places that specialize in this type of repair. The best thing to do is visit this page about power jack repair. They can repair the jack so it is better than new and your problems will be cured. I would ask the other company for a refund. Without the proper tools and experience it will not be properly fixed.
