I tested it on the floor for a few days with no issues like this at all. I should have put more hours on it first but it seemed okay so I went ahead with the tube swap and now this. Hammerhead has the system board for $225 and I think the oscillator board for $85. I really hate to pull this thing down again and change tubes out. If not for this issue I think this 852 would look better in the long run. I already had it setup better than the 110.

No but last I read he only had stock of bad boards but I will ask. Thanks for the suggestion.

Did it start once you ceiling mounted it?
Have you reseated the boards and checked the cables?

Yep, it started once mounted. I have only removed and reseated the system and oscillator board. Cables? The RGBHV cables I have checked at both ends. Verified H and V cable connection, removed, reconnected.

Does a 852 have component input?

Yeah, it accepts component but I think I would need some BNC to RCA adapters (couple bucks at Ratshack I think).

Could the previous owner been using component? Sorry just grasping...I don't know anything about the XGXXX2 series...Just thinking out loud.

I did see a signal entry called component in the list but the previous owner was using an RGBHV cable just like me. There are tons of entries in this thing.

Hope Doug will chime in. I'm not telling you todo this but I actually filled up all my lines from 50 up trying different res/and refresh rates. (an HTPC will do that to you) I went through and deleted all of them except 50 I think. Then started from scratch, Doug said don't delete anything though..so I would just wait for him.
Mike

Doug has helped me a lot but he is out of pocket for a few days so I will hang tight and also look for boards. Thanks for the suggestions and I will try anything at this point.

still doing the same thing. will only lock onto a signal from my old DVD player and then it calls it PAL. It sees it as a new signal every time too. My 1080i signal is trying to come through, flashes off and on for about a minute and then locks onto a scrambled image with unreadable menus.

If you didn't see ANYTHING like this at all while on the floor, and the previous owner had NO issues with it, you need to check your power for voltage on the neutral to see if your house wiring is CAUSING this to happen. From the threads about this terrible problem at AVS, the common theme has been voltage on the neutral of the power going to the damaged projectors...
You'd hate to think it was the case, but maybe it was a perfectly good machine, and has been damaged in the short time you've had it running .... Discovering this wouldn't fix the 852, but it might spare another...(or a new system board...).

Assuming the XG1100 was using the same power it may not be it but the earth ground to neutral should be under 1VAC best at 0 but you will have some depending what is on that phase and is shared with that neutral.
With system board problems there is a chance deleting anything that is stored before that allows the projector to run can have risks esp if there are no problems. The bug a boo is it wont show up until you try to enter a new signal or try to run under a no signal condition. If you didnt use a signal to check the projector then it should have had scrambled menus if you brought up a menu (90% of the time)
Its hard to get a handle on this via posts and not seeing how everything is laid out in the settings or if the signal being sent isnt the same.
If the XG1100 is up and running then use that to check the RGB signals first. Video is pretty straight up if you have it entered right for the connection. Alot isnt being answered so Im assuming the first video input in the entry list is NTSC and not PAL and set to auto with no source lock turned on.
If the XG1100 is working ok (on everything) then you should be able to see how the settings are set in the Info menu and also the settings menu.
Dont confuse component with comp in the sync properties because it can mean composite H/V combined sync where separate will say sep for 5 wire.
Go over all this again and try to verify with the XG1100. If all else fails and it still does it then you can replace one or both boards. There is one other option but hate to think about doing it then you be stuck with a machine that wont take a new signal.
Right now it does sound like a system board or osc but check the earth to neutral voltage. Remove power before re-seating the boards. Might try that again. Doug

Okay Doug, I have a list of things to check when I get home and I'm going to do my best to document exactly what is happening and report back. The XG1100 is missing the tube now but I suppose I could reinstall it for testing purposes. The 1100 never hesitated for a second to lock onto these same signals I'm feeding the 852 and nothing in my video chain has changed save the projector. It's been a rough couple of weeks for me and the wife with me getting in a car accident last week and her mother having complications during a surgery and we are not sure she is going to pull through. So, I have not really had the patience or time to devote to fixing this problem with the projector but I plan to get back at it. A small personal victory would be awesome right about now...

Your not just checking the signals you want the settings and Info menu settings of the 1100 to double check the XG852. If you have a camera take a photo of each page to compare as well as the input list. More so to see if your missing or over looked something. This part doesnt cost anything.
What did the default data menu information say on the 852?

Is this the area that is sectioned off in blocks and has the ranges for Hz and Khz listed? I took a look at that but don't recall from memory what exactly was there. I know that there were like 7 sections, 4 on the left and 3 on the right. After the list on the right there were some blanks that I thinks said "NONE". If I'm not mistaken, section 2 would be the range for my preferred 1080i signals. I'm not exactly sure what this menu does so I left it alone for now. This is just a guess but when the picture flashes up on screen briefly and then goes away, is the projector hitting each input line looking for a matching signal and then moving on to the next one?

I tried a different receptacle and no change. Removed the boards and reseated them and no change.

While I am waiting for someone, somewhere to offer up a system and or oscillator board for sale I thought I would take a few pics of what I'm seeing today. This machine is VERY angry and it's really starting to piss me off. I was quoted $350 for a system board which I really can't justify putting into this machine not knowing for sure that this is the problem. I'm about 5 minutes away from dragging it all out to the curb and buying a plug and play digital. Yeah, I would have to buy a bulb every 3 years or so but so what, for what I will probably have to spend to get this thing up and running it might be worth it. I really want stick with CRT but it's really tough to justify the work I'm having to put into it. This is supposed to be fun. I want to have family and friends over to watch a movie or play games. This feels more like a labor of love at this point and I don't have the patience or the knowledge apparently to make this thing work. I might even consider another brand of CRT before jumping ship to digital but I just don't know right now. I should have known this would happen if I pulled down the 110. I should have left well enough alone but noooo, I thought I could make it better. Now it's all *%!#ed to hell and I have a 150lb paperweight on my ceiling that is loud and pumps enough hot air into the room to cook a turkey. I hate to complain like this but it just sucks when I know how nice this projector could look if it were working. Anyhow, here are the pictures if anyone is interested.

Was $350 for the system board from Curt?
