Look for arcing in the HV (including the connection to the CRT), focus and yoke sections. Since the noise is synched to the screen I'd guess the source is internal, and probably due to arcing.

I have checked and found no arcing.
If it is internal, how does moving around the leads on the external connections clear it up or make it worse? Would providing a picture of the best/worst of the interference help diagnose? Thanks

Look for any coaxial cable having a broken/intermittent ground at one end.
E.g., a coax RF input cable, or the IF cable from tuner to chassis. I've seen it happen with a pickup mic cable (in a remote set). Last edited by old_coot88; 03-08-2015 at 09:16 PM.

I have check every external cable. I have also checked the two twin lead connections inside the TV. I will check all the cables inside connected to the tuners ( I believe there are three and one jumper).
I am attaching a couple of pics of the static at its worse. I can adjust the external connection orientation to almost eliminate it, but it doesn't completely go away (but pretty close).
