Also i should mention, in the pics you only see the brightest lines in the middle of the tube, they go all the way across edge to edge of the internal pattern, but are brightest in the center. it does sound like the jail bar tech bulliten but that was for the 8000-9000 PJ's way back in the 90's this is a 2004 build.

This is starting to sound like the Gozer thread Wink

Ok new discovery, on the vertical lines in the horizontal bands caused from the Astig board. If i disconnect one astig coil connector, doesn't matter which one the squiggles go away , well they are are barely visible and will not show up on screen as soon as I plug in the not connected coil connector they come back.

Try altering your porch settings.

Chip, this is with internal patters and its on all internal frequencies. But thanks.

Did you try a different neck board yet?

Ya know. Normally I wouldn't even think this would be a neck board issue since its on all 3 tubes but since this is a new device you have to account for build anomalies.

Alright, I just thought of some thing. If the neck board doesn't yield any results. Do the lines show up at low resolution? Like 480p?

Hi Ron, ok same with new VNB on Red. I tried all internal resolutions and the lowest one in the marquee has to be close to that.
Now remember i have all external sources disconnected while testing.

Since i first hooked these up I thought it was a Tv-one issue, so i never pursued investigating till i started to look more in depth to the blend zone lines I had.
I always thought those jail bars were part of the Tv-ones. So i started this thread once i took the tv-ones off the video chain and went to my Lumagen and now No sources.

Wish I would have noticed it was a PJ issue and not the Tv-ones earlier as I would have not mounted them to ceiling yet, servicing these above your head sucks !!! Wink

Ok I feel better after the rant.

All thats left is the VDM, but i have no Ultra VDM/CVA rear panel. I know I can modify a non ultra to become one. i have one loose I could do that to, or will I be able to just use the stock board for now while testing? i wont need all the extra convergence and keystone crap for now.

Well my next thought was that since you also have an issue with your astig then maybe thats whats causing this. Believe me I'm going out on a limb here but I think we are already out there. If you can run the resolution down to 480p then you should be able to run a tube without the astig coil. Maybe the coil is causing the problem. It should still focus well without the coil. Remember, astig was never used on early, low res devices. It wasn't until higher res with mass amounts of electron flow that astis was required.

If your not comfortable with that then try a different coil.

I dont need to run the astig as I can get the dots nice and round with the CPC magnets, and the astig coils are built into the focus coils. The squiggles don't bother me as much, its the jail bars that are very noticeable on screen. And that has not gone away with any testing and swapping and changing. I could try the LVPS and HVPS but I don't see how it could be those. Only other thing is the way they route the wires? On theses there all tucked nicely away between everything On all other PJ's there just everywhere. But even that might not be it, I have a different HDM and those wires are just hanging.

Ok your on to something here, when I used the SIZE control the bars move, they either expand or contact.

Now using phase they stay in the same location, so seems that Phase does not affect them but SIZE does.

Also i changed the internal resolutions and the higher i go the other lines in the blown up pic become larger in vertical size and more defined.
At the lowest frequency its barely noticeable.

I need to read the service manual to see what H phase comes from and to what board, most likely the convergence board.

Maybe you should try swapping the power supplies.

Do these Marquee's still use those mini RCA connectors for the coax?
