Hope this helps????
The plug I'm suspecting is hiding behind the 3 wires to the neck boards and is centered between the 3 ICs with the blue stickers

Well first off in your image of the Horz control board which is a little blurry, it appears as tho that wire is connected to TP5 which is Horz. feedback. Never seen that wire before. But then when you look at the connector of that wire it was actually an RGB wire that someone used for what ever reason they had to install that wire. I could guess all day as to why that wire may have been installed but without a whole lot of other info, it would be a guess. Unless someone else chimes in that has that wire in their projector further investigation would be required.

Here's where the wire comes from on the horizontal board.


And here's where I'm hoping it goes.[img]

Well it's not connected to TP5 and it's still hard to tell exactly where they are connected to on that board. So still no guess here. Are both wires in that black wire connected to something on that horz board?

Once upon a time I would have been able to tell. Now.... Oh well I'll buy a magnifier next trip into town and get back to you. I'm encouraged anyway: It's gotta be a mod from what I'm hearing and the wire position and length make sense. Otherwise there would be 2 things out of place and since there's only 1 at each end well it makes sense that's where it goes.

Both conductors are soldered together at the board side of the plug and connected to the top of the little orange cylinder
(I don't recognize what the orange cylinder is) so that would be one conductor.

Well it appears as tho the wire is connected to TP19 on the RGB board which is Horz sync. If we then go back to the horz control board your pic is to blurry to be sure but it appears to be connected to TP17 which is Horz sync.

So if all the "appears" are correct then it would probably connect there.

There must have been a problem somewhere because that wire should not be needed. It should be able to pick up the horz sync through the regular board circuitry.

Sorry about the blurry pics; all I have for a camera is my work phone.
Anyway I'll plug it in and say thank you very much . I'll let you know how it turns out.

Plugged it.
Powered it up.
No smoke or funny smells.
No nothing from any tubes (tubes all turned off) So I think my red glow with red off has gone away. If it comes back I'll check the blanking first.
It would be nice if there was a way to initialize the settings before turning on the tubes but I haven't run across that. I think I'll just check all the settings after I adjust G2.
So far its been a good day so maybe continue later in the week.

Thanks again

Turned up G2 green until tube face glows then turned down.
Turned up G2 blue until tube face glows then turned down.
Turned up G2 red and nothing happened ... no glow.
Any thoughts on what I might have screwed up or where to start checking.?

Once I got the new red tube in and connected I started with your instructions for G2 adjustment then the sub-brightness. This seems like a real good good starting point.
Anyway I haven't connected an input or tried to do anything but set the G2 knobs.
I'm stuck in a rut where each thing I try I get further from watching and enjoying.
Battery died. Replaced battery.
Blue neck board died. Got neck board fixed. Red won't shut down broke pin on red tube.
Replaced red tube now red tube won't light up.
Enough of my complaining.
Sorry all I've tried to do is set G2 adjustment.
Thanks

Test 1 on remote
Turned up red G2 knob slowly. Red tube glowed for about 1/4 of a second, just a flash. Not enough time to see if a pattern was being displayed. I can't get any glow from the red tube now no matter how far I turn the red G2 knob. Turned power off. I'll try again from cold in an hour?

Could the bent pin on the red tube have damaged the red neck board?

Forget about the glow for now. Make sure all 3 tubes are turned on. Go into sub contrast and set all at @ 70. Go into sub brightness and set all to 50. Main contrast at @ 70 and main brightness at @ 60. Turn the red G2 up to @ 3/4.

Bring up a test pattern. Do all 3 colors have a grid?

Blue and green respond to adjusting to the settings you advised but rather than test pattern mostly glow with lines.
Red responds almost like a switch is being turned on at about 2/3 adjustment on G2. This response is so abrupt that as a reflex I turned it back down. Then turning the G2 knob back up results in no response as before setting the bright and sub-bright, contrast and sub-contrast.
I hit test 1 which should be crosshatch but looking into green I don't see a test pattern only a green rectangle . I took a picture of it, It hasn't come through to my email yet, not that there's much to see except a green rectangle.

Same thing on blue.
Except for the brief flash while turning up the red G2 nothing on red.
