I was not aware of these things. I knew of a board or two not working, but not to this extent.
Anyway, I'm not good at charging for things that may be out of warranty, so I've just been repairing what failed.
In your case, I'll take over the warranty on your VIM, neck boards, LVPS, VDM, HDM, and any repairable section of your HVPS. Did I miss a board or two??, Is so, just consider that 9500 you purchased from Paul under warranty by me. And so that you'll know. I only did upgrades to the LVPS, HDM, HVPS and the neck boards and VIM.
So keep your head up, you'll only have to worry about shipping for the next 12 months.

Thanks Mike....so for my current problem with the VIM should I be sending it to you or Curt?

The projector was a mess when I got it from Paul. The LVPS and HVPS were DOA and the vertical board was not working. The neck boards (also modded by you) had never been installed on the LUGs and needed some minor mechanical mods to fit on the tube, the LUGs had not been installed and the blue tube had no glycol in the LC chamber. The green tube had the problem with secondary emmisions and the Vidikron case that it came with was for a Vision 2 not a Vision 1 as it was supposed to be, so it did not fit over the lenses on the front of the case.

I can attest to all of these things. I helped Chris with a couple of them.

I do have a spare (an old 02 VIM) that I used to troubleshoot the problem. I'll package up the broken VIM today and send it to you.
I know this isn't an easy question to answer but what do you estimate the turn around time will be?
Thanks for the help,
Chris.

Not sure, but I'll get right on it. I have a few things to get out in a few days, then I'm chilling from there until I keep the marquee mods back in next month.
So by the time it gets here, it would be perfect for a good turn-around.

The board is shipped, you should receive it next Thursday. I'll PM you the tracking # when I get it later today.

I have a few things on my to-do list, and one of them was to get back to this and do some research on this problem before the board gets here. As I've said, this particular VIM problem seems to be related to tube flashing and high voltage. I've looked through my tech stuff and it appears to be more common on 03 VIM's only.
I knew I had read somewhere that before the tube was sent to VDC, there was some level of testing done. In the link below,
there's some history from this Marquee before the changing of the LUG. It's from another thread, It appears that there were a many hours involved in testing before the tube (LUG) was sent to VDC and no where in that thread is there a mention of the HV going out:
I'm also wondering If it's not a good idea to test the projector pulling one or more of the HV wires from the splitter, or If there's a better way to do it.

I actually never ran it for that 100 hour burn in, I decided to just send it to VCD to be fixed. I had never had the projector running for any extended periods of time until I got the tube back from VDC.
As for testing with pulling one or more leads from the HV splitter, I did that and the problem is still there. I tried disconnecting each of the HV leads from the red, green and blue tubes one at a time.

I'm not trying to d o a finger pointing thing here, I'm trying to get to the bottom of this problem. Which by the way, is not only on your VIM.
Also, I'm still puzzled as to how this problem happen only after you put the green tube in the set, and it was not noticed before. I do recall you also posting that it was directly related to putting the tube in, because this problem was not happening before. I also recall that you had put some time into getting to the bottom of this, but now you're saying you only turned the set on, noticed the problem, removed the tube and sent it to VDC. I'm not remembering things like that. In fact, before you send the tube to VDC, Charley will usually ask you to burn it in first. I know we had a similar problem on the stack setup that we cured ourselves with time and increased contrast.
I'm really puzzled why this "new" problem only surfaced after you put the tube back in..
| nuttall_chris wrote: | So after finally getting my green tube back from VDC to sort out the secondary emissions problems I go to do a full setup and a new problem has shown up. After the projector fully warms up the HV starts "randomly" restarting. Sometimes it goes out and then instantly restores at full voltage, other times it shuts down and can take anywhere from two seconds to a couple minutes before restarting and refocusing. No fault LEDs come on and it seems that if I shut down and then restart the entire projector with the remote, the problem goes away but then comes back in about 15 minutes.
I have tried swapping out the HVPS, the LVPS and the HV splitter but the problem still comes back.
I still plan on swapping out all the boards in the projector but if anyone has any suggestions it would be appreciated.
Is there any way that this could be caused by the green tube?

I guess what I was trying to say is that I don't know if the problem was there before I put the green tube back in the projector after getting it back from VDC. I hadn't run the projector much before sending the tube to Charlie.
I hadn't seen the problem before putting the tube back in so it does look like it may be related.
Is it possible that whatever was causing the secondary emmissions in the tube somehow caused this problem with the VIM?
I need to start keeping a log book when I'm trouble shooting problems as it would have helped in this situation.
Chris.

I want to get to the bottom of this problem. I know what it damages and how, I need to better understand why it happens and what possibly causes it.
It would be very helpful If you did keep a log from now on, considering that I'll be covering most of your board repairs for the next year or so.
I'll do that because I think you paid too much for that projector to be in the state that it was in. I don't think It was Paul's intent to rip you off, or to sell your something that had problems, I think he just overlooked some things as we can all do from time to time when dealing with stuff like this. I know when he purchased that 9500 from a local guy, the guy had also threw in several boards and power supplies that were not in the projector that he had laying on the floor when I went to his house. I think the person that you bought it from may have put a few of the wrong boards in that projector, not knowing which were which, or that the extra boards that came with the projector did not work, or had issues. I don't think he had bad intent, he may have done the best he could with what he understood at the time. And since my mods were associated with the sale, it seemed like the best thing to do.
So your part in this warranty is to keep a log..
