If you do the grounding, make sure ALL OTHER BREAKERS IN THE HOUSE ARE OFF!!
Also this should eliminate a bad ground in the LVPS, but make sure the new ground goes to the mounting screw on the LVPS.
In addition, with everything else turned off you eliminate other potential sources of problems.

Thanks Jim. I have not done the second ground yet. However I have dug up the house ground and the rod is fine and the bonding bolt is tight. The Bare copper wire is also not damaged in any way. I also turned off every other breaker in the house except for GOZER's, this should have eliminated and false grounds or loops or other interference sources, so I think that one is eliminated. The Herringbone remained.

Now that the clips are back on that arcing is completely gone. The Herringbone remains. I have removed all of the wire looms from the Motherboard that go to the Neckboards and cleaned both sides[ MB side, NB side, wirelom sides] and replaced them, no difference. I have not looked at the the copper ground wires on the tubes yet, but I have crimped the wire end that goes to the Neckboards, they are very tight.

I am going to Lowes to buy some grounding eyelets to make new ground wires. I will be drilling the Heatsink out by the outer edges and use a self taping screw there and run the new grounds to the video cable clip screws.

The next question I keep thinking is, what grounds the mother board itself? Could there be a bad ground on it?

I'll check in when I get back.

Heh the loaner parts are here i am going to try the CLM First.

So before I turn GOZER back on It is running without a focusboard. Stig amp wires are off, I'll let you know...

Put the CLM in Herringbone still there. Next I will remove that CLM and replace it with My CLM and change the Neckboards one at a time, starting with the most suspected one first. That is the one on the red tube that is displaying the most Herringbone.

Strangely, tonight dturco will stop posting, and UFO sightings in the Maryland area increase.

Coincidence? I think NOT!

The neckboard being replaced has nearly solved the Herringbone issue, as I always thought it would, this is the first time I have had an Extra [ EDIT NECKBOARD } board to put on in my home. The herringbone is barely noticeable, in fact I think its just regular fuzzy type interference not the big wavy lines I was seeing.

So now do I continue with each neckboard or just do the VIM? The phone cutting off is still there.

Good one Curt

I would do the vim now.

VIM it is.

Ok VIM is in, no change to the picture. The slight distortions are still there and the cell phone still shuts down as soon as the P/J starts and comes back on as soon as it is turned off. Confused

But now at least it doesn't look like the tube is going to explode from the Herringbone wiggling all around on it.

Is it time for a new thread or to call the Motherboard[ship] Wink

Next?

I can't remember for sure, but I think there are ground straps inside the box that you slide the hdm and focus card into. Might not hurt to make sure they're in place and secure. As this is the source of most noise maybe just give it a bend to make a little better connection.

Ok at least we know it was that one VNB, possibly the others also? . Was there any improvement with the Stock VIM or was it the same?

Oh i see what you saw, where he said " the vim it is!" he meant he will check the Vim next, not that it was the vim causing the issue.

I am done with the swapping and all is working well. I was on a ladder swapping the VIM while talking to Mike. It is true and correct that Mike lent me a VIM to swap, I did not have a Neckboard here, we just began running parts to the test mule after the VIM swap trying to find the issue which did not appear on his test mule. I have edited the previous post to say Neckboard as I was not clear about that.

The issue has been resolved. Mike is making another set of boards to give back to me with out the Microns . I am satisfied that will be as much as can be done. I will give him back these boards so he can research them.

If there is anything else it is me or GOZER and I will track it down in... A NEW THREAD Thumbs Up

Sorry, haven't read every thread and post. Did this solve the cell phone issue as well, or just the herringbone?

I'd say leave it for now, make sure that the herringbone is gone for sure.

Then.....

START ANOTHER THREAD! Very Happy
