|
|
so i was just starting to consider getting the latest MP mods (i already have an older version) and Dragan's board maintenance/upgrades when all of a sudden, my 1996 pj developes the following.
about twice an hour, all three tubes softly (over about a 1/4 or 1/2 second) shut off for approximately 1 second and then turn back on TOTALLY out of focus. It refocuses over about 1-1.5seconds and everything works fine. there is no unusual or noticeable crackling, poping etc.
so, what do you guys think it might be? and is there any harm in continuing using it as is or what are the risks?
thanks guys!!

Sounds like the HV is going off, and then coming back on. The same thing happened to me when my 8000 blew the HVPS, it would go out of focus, lose picture, and then come back on with the picture out of focus. First it only happened every once in a while but with time it was happening constantly.

I had the same problem with my 9500 Ultra with MP mods. Turns out the problem was with the modded VIM. I sent the board to Mike as he said he would fix it. He kept making promises that he would fix it and get it back to me but that never happened. After 6 months of unreturned emails/phone calls I was finally able to get Mike to send the board to Curt. Curt fixed it and had it back to me in less than 1 week.
Apparently one of the protection circuits on the VIM was shutting down the HV supply.
Try swapping out the VIM and see if the problem goes away. If it does send it to Curt to be fixed.
Chris.

If at some time you still considering MP mods, keep in mind that they are not yet available. And when they become available, it will be done and handled by Tim and Curt.
And since you have an earlier version of the mods and if they have the potted material that i was once using some time ago, also keep in mind that they may not be upgradable. Or the boards may not be able to be fully upgraded.
Any previous version mods would most likely be done by me, and that's not something that I'm doing for now. I'll announce that later this month.

As Athanasios said, it is most likely your HVPS.
When you mentioned that it comes back in "out of focus," that indicates the HVPS.
That's a lot different from the problem Chris had. His problem was a apparently the video mute section of the VIM. When that circuit activates and deactivate. It will not cause a notable focus problem when the picture comes back.
Also, Chris had a modified board that was subjected to arc or surge damage from a leaky high voltage problem. When that problem exist it can do serious damage to a VIM and sometimes other boards. I made several attempts to fix that problem and the board was sent back once or trice. I was even going to swap it out for an 02 VIM, but did not feel that good about doing that, especially since the problem was so difficult to isolate. And the board was not under my warranty or purchased from me.
So these are two different problems, with one being caused from shock or external damageto the board. Your problem seems to be HVPS.

Incorrect, the problem on my board did cause the image to go out of focas and refocas as the image came back. The image would instantly go black then a few seconds later it would come back, out of focas and over about 1 second the image would refocus.

I'm suggesting you swap the entire VIM with another VIM not just the extra input card. Your problem may not be the same as mine was but it's an easy test to do. If this doesn't work it's likely the HVPS.
Chris.

hahaha. i just wanted to get through 6 episodes of chuck, and 5 heros...all on the TIVO, then i was going to give the theater a rest, pack things up and get some freakin yardwork done!!
if you happen to have the spare parts mentioned above, pm me.
the guy who bought my last house (and marquee 8500) is an old highschool pal, so i can probably ask if i can borrow those parts and swap them out.

Right, you'll have to locate a pot supplier in the US and have them retool to repair Spellman's. You know you want to do it

that's not the problem, it's getting to the crap inside there. I tried digging around in there once on an old 34KV supply and it's more like Archeology and electronics repair.

good luck, even Spellman won't touch these and they made the dam things.

There's so many pot suppliers in the US, how would you know which one to choose? 
Plus, I dont think they could fix your problem but it would be fun to watch.....

I had a letter from a "highvoltage power supply repair shop" just down the road from Curt. Guess he couldn't do any thing with the POT either. Curt said he didn't manage to repair the two Marquee supplies he sent it.
Too bad, he could have been our B.C. Bud

just curious, what does it mean under the "potted material"?
