Thanks. Sounds like an idea... But ordering De Natured Alcohol will a be debate. Thanks none the less.
Unless I make it myself ..

So I've been cleaning the hell out off CLM and LVPS today and in an hour I'll fire it up again. Hopefully it wont turn into a nice cosy fire. I accidentally snatched a cable from its socket and had to solder a little but think I got working again.
Oh.. and Mike, I apologize, but your board has nothing to do with the noise I'm seeing inside the lens when picture is muted. I tried my old board the other night and sure enough it was the same, I must have remembered it incorrectly. It takes like 5 seconds and then starts to be noisy. That part probably differs a lot also, but something I noticed last time. But doing that got the bad connection back on again, but got it sorted in like 30 minutes this time. If all six red dots on moome lits up, then I know it wont fire up and I just turn it off and reinsert the board until only 4 lits up, and then secure it that location. It works.
I didn't have to buy the stuff needed for the P14 mod as I set it back to 6,34 V the way it is. Will keep an eye on that and see if it drifts.
EDIT: Changing the mini RCA jacks did not change the green noise.

Back to the drawing board, the cleaning did nothing at all with the ghost pattern. There are more boards left, I know, but left those alone as they look brand new, except the one on the far right (seen from the back) that has very faint green outlay and just looks old. But fresh and clean at the same time. Looks if it comes from a different batch. Will clean those during the weekend.
EDIT: A couple of days I removed the chips and just cleaned them with my hand, that caused the grid pattern to spread and almost filled 2/3 of the image. Now with having cleaned CLM it's back to basic size of ghost pattern in my drawing. May be CLM after all..

the extra grid section you drew is the marquee menu overlay. There was a big thread about it, basically the built in video on the CLM never turns off, the PJ just tries to overlay active video over it. There's no fix, you need to turn brightness down to hide it.
For the broken width coil, hold it up straight and cover it with hot glue.
If your P14 voltage is really 8 volts then your lucky if any light is coming out of the tubes at all and that all 3 cathodes aren't completely stripped.

this can't be adjusted, the tim pot, "adjuster", is bad, probably say's MEXICO on top

Its the CLM a bad Pixel generator. When I tried to do the mod where you shut off the Pixel generator , I had a switch in series and for some reason I got that same brighter area. I had to remove the switch and go back to stock and repair the trace I cut. Then it did not go away completely. And no amount of lowering the brightness or contrast fixed it. So I'd look for a new CLM.

I had a feeling it wouldn't be solved that easy.
But the tubes are putting off good light. If you need me to I'll prove to you.. looks good. But wasted a whole good year with high voltage. Can post up grades on the matter. But like you say.. I have to set brightness back to get rid of the "overlay".. you are right about that. And I always felt that since the very beginning...
Btw, let me tell you a story.. I almost ruined the pj the other day..
I was to believe there was a trim pot "on the west side to trim, trough the grill bars" and while I was opening up the damn thing.. I only found one, but only on the north side (looking on it from the front side) "Yeah, there it is." Vaccumed it, (all I could do at the time) put it back together and started to fiddle with it 3x360 degrees turns each side.
Well, nothing happen.. stayed at 7,68 ish all time. Put it back together... and then realised I had screwed with wrong trim pot on the north side, saying 85 V,.. Put it back to where it was. Took notes where I was. Unbelievable I turned it 3 times counter-clockwise and 3 time clock-wise and not ruined the pj. LUCKY I guess. Stupid some say.
I then lit light from the side and saw the "real" trim pot from the west side as it should. Fiddle with it.. and was 6.38 almost immediately. It's at 6,33 now.

oh I believe you, at 8 volts the tubes will be very bright, like burning a candle at both ends

If it was my machine, I would either do the modification, buy a new LVPS with the modification done to it, or check it before watching a movie every time. It's that important

This is extremely difficult and not something a hobbyist can do themselves. AAMOF, I don't think it's available anymore

Will indeed check the voltage every time before a movie. As long as it stays at 6,35 ish it should be ok.

Try replacing the caps on that CLM. That usually solves the problem with VERY noisy CLM's

I could probably do that sort of thing. The only caps I see are the C49 and C50. Into what?

There are 8 tants on there that should be changed. The four at the connector should be replaced with electrolytics, the remaining 6 can or would make more sense to use tants.
For the electrolytic I would use anything in this value range, 50 to 220uf - 25vdc - for the other 6: 22 to 33uf 16vdc
Most of the tants on any CLM with high standby hours on it, should be replaced.

That's probably way over my head so I'm going to buy a fresher CLM and see what happens.
And Dragan, you were right, that P14 has to go because it drifts like hell. Started up at 6,39 and within seconds it was 6,43-6,44 where it stayed. Hopefully I will pull that mod off. But that's weeks from now because I'm all out of money.

Oh.. that would be LVPS P14 mod. It's like 40 $ in parts and shipping from England. I could do that I suppose.

If you're talking about the filament pot. I have them and can send you one for the shipping cost. because your LVPS is way too unstable
