Hey guys, there is a fairly loud ringing sound coming from around the flyback area.  I did not notice it until I started running the machine without a (noisy) HDD.  The ringing sound is directly related to HV, and it gets louder when bright white objects are shown on the screen.  I also noticed that the CRT picture shifts down a little bit whenever the CD drive spins up.

Do you think a recap of the analog board will make that go away?  Has anybody ever recapped one of these analog boards?
