Here are all 3.

The two PJ's are different Tube size's so you can not swap tubes or lenses. However every other board will switch over with the exception of possible the tube neck card or video amps as we call them VNB's ( video neck Board) .

These are very easy to work on and and also easy to trouble shoot. id keep them both for parts and try to get the 9 inch unit working.

First thing you need to go buy is some Electronics contact cleaner or better yet DeOxit from radio shack. While there grab an ic chip puller so you can remove and clean some chips on the control board. we will get to that later.

First thing to try is to re seat all the boards in the PJ.

here is the layout fro the Marquee and clones. Curt used an 8500 not the 9500 fort he pics but they are the same PJ in essence.

So now when firing up the 9500LC( 9 inch set) are there any error lights lit up on the Control board
in the rear of the PJ and look for any error lights up front with the lower power supply cover removed
on the Low Voltage Power supply(LVPS). it is locate on the bottom left front.

we'll go from there.

I agree, it's not the best idea to get a newbie with no projector or electronics experience to pull chips and fill the chassis with contact cleaner.

Oh, and since nobody's mentioned it... Since you're carting these things around in a van, the one with the metal lenses that you just picked up... Keep that bad boy out of the sun. If sunlight enters the lenses, it will damage the C-elements (lenses) attached to the tube mounts. They're a pain in the ass to replace. Just make sure you throw a blanket or something over the machine if it's anywhere sun might shine directly into the lenses.

Well i guess i have too much trust in peoples abilities. Its not hard to do. You never learn if you don't try.

Imagine if I listened, back in 2005, to Mac and Chip when i had a LVPS issue. Id never have touched anything electronic again.
I knew nothing at all , But i was determined and taught myself. I'm glad I did. TSE encouraged me to ignore everyone and give it a shot. That was a pivotal moment in my life. Now i am not afraid to try and fix anything .

Jsepps -

Just want to chime in here -- you are a) one lucky duck and b) don't feel overwhelmed -- Tim, Nash, Dragan, Curt, and others will see you through this! Wink

Even something like the high voltage power supply (HVPS) swap (IF it turns out to be bad) won't seem crazy after you've done it!

Matt, who is wondering who takes these to a goodwill...there is a guy with awesome toys!

OK, I'll start from scratch. Here's what I recommend:

Pull the lenses off both projectors. One bolt in each corner at the 2, 4, 8 and 10 oclock positions will take the lenses off. Post a pix of each set of tube faces. If you can see wear through the lenses, it will look worse with the lenses off. That's a starting point. Then, rather than jumping into messing with stuff at the chip level, let's see if we can't get the Vision 1 running.

Do not take any other screws out other than the ones that hold the lenses on.

Don't laugh, I had a guy do that once to a first generation BGW electronic crossover. It was one where you changed resistor modules to change the crossover frequency. He dumped literally 3/4 of a can of contact cleaner into the DIP socket, and the whole unit was swimming in the stuff. Of course he had problems elsewhere in the sound system....

I don't exactly know where the OP is on this, since this topic seems to be a bit all over here, but if the OP is still trying to hook up a PS3 (assuming its a PS3) then there should be (at least there is with the Xbox 360) a VGA Cable option for the PS3. Otherwise, You could always go from the PS3 with HDMI to DVI cable and get a Female DVI to female VGA adapter, and finally use a VGA to BNC cable and voila - PS3 in HD goodness Very Happy

Lot of converting but it should work since the HDMI signal is the same that would be output with a computer video card that has HDMI.

Just my 2 cents, hopefully you wont need much more Razz

RayN999 · Posted: Mon Apr 23, 2012 5:23 pm Post subject:

Jeremy, the HDMI doesn't carry analog signals, so the last step of DVI to VGA and then to BNC won't work. There are Component video cables for the PS3 which could be used with an external moome (or similar) to then transcode to VGA. That would probably be best bet for maintaining any kind of HD quality throughout the chain. Or if going with a Moome box, could use DVI or HDMI to get HDCP handshaked VGA out of the deal.

I might be wrong....

Yeah, I'm pretty good a electronics tinkering but I don't think I want to go spraying Ito the unit at this point. I think for the time being I'll just worry about the one that works. Under the diagnostics on the non working unit I'm not getting any errors. It only flashes under "C" when any button on the remote is pushed. Same as the working unit. Neither flash any errors.

Did OP ever post where he was from?
