Replaced battery on CPU board.
Replaced cracked resistor on blue neck board
Red G2 fully left lines are unaffected.
1) Are the resistors that I cracked one of on the blue, part of a bridge that the red knob adjusts ie) maybe I have a crack in one on the red board.
2) Are the neck boards also referred to as the focus boards?

This may:help
Adjusting the red knob has no effect except at the extreme end of the adjustment fine red lines show.
I'd be happy to post pictures of what I'm seeing but when I try I get a message that that function isn't available unless the pictures are already available elsewhere on the net.
Thanks

Does the red knob work on the green and blue??? If so, you probably have a bad neck board or red tube.

I turned all three G2 little red knobs fully left. Blue and green respond pretty much the same as each other: two distinct levels as the knob is tuned to the right, the raster becomes bright so I turned left full then slowly to the right until the light just comes on looking into the lens. The red also shows response to adjustment in the same way except that fully to the left there is a glow on the face and lines horizontal.
Can I assume these boards are interchangeable.

Other then 1 neck board being mirrored of the other 2 for clearance, they are the same.

The plug is different on the red board. It won't swap with others.

Green has a white plug on the board with a cutout that mates with a feature on the tube also white. Red has no cutout on the plug and the tube has no white locating feature, just the pins.
Point to the instructions for posting a pic will you.
Thanks

Sounds like the white pin holder on the back of the tube came off with the neck board. It should pop out of the socket.

Your pictures maybe to large to post directly to the web site. Try loading your pictures to a host site like Image shack. Then take the image link and post it here.

Ok yes there is reason the boards are different. The green will not fit onto the red tube there's a circuit board in the way. The red board sort of fits onto the green tube if you get your tongue on the right tooth and don't mind it hitting the HVPS.
Still working on the pics
I should just get the red board in the mail to you.
I'm still scratching my head as to why I'm having 2 or 3 boards go south at the same time.

You guy's are driving me frigging mental.
Are you sure you don't have the red cut off?? Try 65[code] which toggles red cut-off and see what happens. Are you sure you don't have a bad connection at the red BNC on the rear.
Another thing that can cause diag lines on the tube face (with a X600 chassis) is incorrect left and right blanking. Those settings would also be lost with a quickie battery swap. Try looking directly into a lens while moving the left and right blanking to see if it effects the lines you see.
Turn on your source and confirm it and the cables between source and projector. Re-seat cables at each end.
I don't know what channel the projector is trying to boot up on but once it is up and running do a 29[code] (clear active channel). Next do a 54[code] to insure the on screen display is active. With the on screen display active you can look into the green or blue while you toggle red cut-off (65[code]) to insure it is on. If the projector will stay running now, with the source on, do a 4[test] (gen-locked test pattern) and look at the tube face. The settings after clearing the active channel should be low and small enough as to not harm the tubes. Cycle through the available test patterns until you get a center cross. While looking into the lens on each tube, raise or lower each individual colors brightness and contrast to 50. then press the static button to put static brightness to 50 and static contrast to 70. then while still looking into each lens set the G-2 knob on each neck board until the raster is just seen behind the test pattern.

I posted this a while back in your thread.
The red neck card is just reversed to the other two have a second look you will see what I mean, I think it fits into the chassis better that way so the tube can swing fully, Chip Scott or Ron would know better.
Make sure it is your neckboards, I had quite a few problems on my 4600 but bearing in mind how old it is and the lack of maintenance by the previous owner I think I got lucky. So far I have changed out the HVPS and the vertical board and two of the three problems I have seem to be sorted out, thanks Macgyver, bear in mind the shipping company dropped my crate from 4 feet according to one of the staff at shipping they were on the verge of telling me it was written off.

You have to toe out the red tube some so that it will fit. Your just doing testing so it doesn't matter that the tube is not projecting correctly. If it wont clear well on the green, try it on the blue. I have swapped them around many times for testing while repairing.
Chip ole boy....  Even if the red was cut off and/or there was no input connection at all, he would still be able to turn the red tube completely off with the G2 adjustment. He claims he can't along with the lines.

You need to verify it's not the tube first. Which I don't think it is, yet.

Heading out to get some silicone, then I'll stick that little piece back onto the red tube..It is kinda loose on there at the moment. Maybe that's related.
Hopefully get to it later today. For clarification: Red turned off by holding button (red) on remote. Green and blue off the same way. Turning red knob on neck board shuts down all glow on face of tubes with the exception of the red that shows lines. No input at RGB board.
