I bought my first guitar 2 months ago. It is a Epiphone les paul special ii. The D string of my guitar sounds little odd. It has high frequency noise on open D string. The odd sound becomes smaller on 1st fret and it disappears after second fret. The sound only appears on the D string. I hear the high frequency sound when the guitar is unplugged. It sounds to be originated from the bridge.

The soundtrack shows the high frequency noise unplugged

What causes the problem of that sound and how can I fix it?
