|
|
Hello all,
I am new to this forum as well as new to the crt market. I am excited to get started with the crt. Well here is the deal. I aquired the 9500lc, it is from 1996. I fired it up and onl the red and green crt were on, no blue. I then turned it of and started to tear the projector down to see if I could find any wires disconnected. As I got down to the tubes i noticed the green tube looked different than the red and blue tube. If you look at the pictures you will notice there is more adjustments that can be made by the magnets on th grren and not on the red and blue. Also I did notice that there were no wires unpluged not to allow the blue to light. Also the red crt does not look as bright as the green. If you look at the pics you will also notice that there is no burn in on the crt's. Can they blow out with no indication that they are bad. Is there a way to test them to see if it is the crt. Any help would be greatly appreciated. Thanks

Is this the 9500 with the bad blue that was listed on Ebay?
I would start by swapping neckboards and seeing if the tube lights.

Looks like the red and blue are stock, the green is a p43 so the phosfor is faster (useful for simulations) and may have also been stock in the machine.
Looks like the green also has four pole magnetics while the red and blue have two pole.
None of this looks too out of the ordinary though I would guess that the green is a replacement tube.

This set had 61,000 hours on it. That's a LOT of hours, and that green tube (and possibly the others) is most likely orignal stock. Yes, tubes can indeed die if they are left sitting on with no light output. CHances are your blue tube is completely shot, the red is weak. THe thing to do here as a newbie is transplant the blue tube with the red or the green. If the blue still does not light up, then the tube is bad and needs replacing. I'll bet the red needs changing as well. Again, very common with high hour sets.
Others might want to walk you through swapping wiring, but since you're new, swapping a whole tube assembly will be easier than swapping signal wires on boards that you're not familar with at this point.
Check the tips section of my website, the Marquee area has lots of pix on how the tubes come out. Should take about an hour to swap two tubes, 1/2 hour to swap them back once you know how the set comes apart. You do need to have all three tubes installed and connected, so swap tube locations completely, don't leave anything out and MAKE SURE THE WHITE G2 WIRE IS CONNECTED TO THE CORRECT CRT PIN when you do swap tube sockets.

Hi! Welcome to the forum!

You don't.  I put a limit there so that people won't overload the server with photos downloaded directly from your camera. Your photos in the first post are over 400K each almost 2600x2000 pixels in size. About 4x more than anyone can view on a screen. There's no reason for them to be that large. Use any number of image tools to reduce the image size 10-fold and the resolution by 5-fold and everyone will still understand what the images mean.

Umm, yes they can. If you're running at less than 60Hz, you might see flicker, but for 60/72Hz, they are fine.

The import thing to know about P43 (fast) phosphor tubes is that they cannot be used for movies/home theater.

My first Marquee 9500 had a P43 Green and it looked just fine at 60Hz, with no visible flicker.

And this is one of my pet peeves!!!! Is there any reason why people can't just use thumbnails in their posts and let imageshack or the like host the pics. Everytime I click on Peter's(Cineremax) thread on AVS, I have to wait to download his thousand pics. Other threads are like that as well. I know the screenshot thread will be like that, but do others have to be. Plus, I run 1280x1024 and some of these pics mean you have to do horizontal scrolling. A thumbnail is an easy way to avoid all of that plus put less bandwidth demand on this site.

yes the filament lights up on the blue. I did do what curt said to do and switched the green and blue. Still no output on the blue.

Kal- I think that was posted on avs way back when, but I've talked to Tim and Terry, and we've all used P43s in HT with no issues.
cgraba, you need a new blue tube at least. Probably a red as well. I'd post in the buy/sell section to see if someone has good used ones, but at this point everyone is looking for them. VDC charges $1650 per tube for a new one, you need to send your old one in so they can install the new tube. There's a company called 'tubular outlet' that will sell you a new raw tube for $985 on eBay, and they also sell used ones for $250, but it's a royal PITA to swap those tubes into the Marquee hardware, not something I'd recommend for a newbie (but there are instructions here on the forum somewhere on how to do it).
Before proceeding, I'd check the G2 levels on the green tube, as it's probably on it's last legs as well. If it needs all three tubes, I would not proceed, and I'd part the set out. You can find another 9" set for less than it will cost to retube yours. With the HD10L lenses, you're stuck with a 72" image diagonal at max anyways, and most HT owners want somewhat larger than that as well, so there's more money you need to throw at that unit.

that means nothing. The filament, or heater, will light up but it's the cathode that is stripped. All dead tubes still light up in the neck, just not on the face.
I think we should make this thread a sticky. Call it something like "So your buying your first CRT and it's from off e-bay"? I think it would be helpful for other newby's who know nothing about CRT to understand just how deep in over your head you can get with one of these things. From the Add on E-bay, it made it appear that all you had to do was re-attach some wires and everything is hunky-dory. Well as some of the old timers guessed in an earlier thread, it turns out this thing is a basket case. Even if you spent another $1K and replaced all 3 tubes with used ones, plus new boots and fresh Glycol you still have a chassis with 60K hours on it. You still have to do the P14 mod to the LVPS which this machine really needs, the anamorphic mod to the VDM, plus there are probably 2 dozen electrolytic caps that should be replaced to make the machine stable and perform well. This is also assuming there are no other common glithces which you'll see with this many hours like control module, HDM or Focus board.
Curt's right (as usuall) on this one, it's an Organ donor. If you part it out you might get most of your money back.

OK now you have your pep talk from Dragan are you ready to proceed ?
Don't mind Dragan , he is a motivational speaker who works on Crt's in his spare time so some of his positiveness flows over here on the forum .
He who hasn't purchased a 60'000 HR STANDBY set and defended how these chassis are good for 100,000 Hours and proceeded to sell original tubed projectors CAST THE FIRST STONE.
cgrba
Your odds of Burnt out tubes are 97.65% BUT first read the manuals and learn how to go into the service menus and just check out the G2 settings There is a good chance this set has been fiddled with and the drives are set really low (doubtful but very worth three minutes time )
The fact your blue tube's filament light up with no output means probably a tube with weak emission BUT could still be low drive settings .
| Quote: | Also the red crt does not look as bright as the green.
|
This is Very normal !! Your green outputs more light than red . don't believe me look at all Dragans tubes he has for sale Green is burnt and red isn't .
You bought the projector Knowing the blue would not work so I hope you knew you Knew you might have to put some money into it . It is an older set So you will need to do the VERY SIMPLE and CHEAP filament voltage mod .
WORST case scenario And ALL the tubes have weak emissions and need replaced then you Can buy some pretty good LUGS from Tubular Outlet
Not perfect!! But for $750 you could re-tube your 9" projector, throw in some coloured C elements and a flush and around two Grand you have a pretty Good 1080p CRT projector .
Bruce
PS Just Razzing Dragan, he is a pretty good guy and will help you out .

Yes these machines will easilly run for 100K hours but nopt on the original set of tubes with P14 over-voltage. The chassis requires work and maintenace along the way as well and why Curt and others are the in business of doing that. I mean why lie to the guy now, that thing needs some major work done and everyone in this thread understood that.

Too bad the OP only found the forum after he blew $1k + freight but its' time to accpet that the fact that it's got dead tubes. Swapping them around and checking G2's won't help here.

You mean those LC tubes in the for sale section, theyre clearly labeled as "needing a new green for correct color balance". Unlike the OP's tubes though all 3 of those have normal light output. Here Bruce, put on your thinking cap and read it for yourself

you know that for a fact huh? How many 60k hour marquee's have you worked on I wonder? At 40K hours so many of the electrolytics are shot that it can actually damage the VNB's, cause poor focus, video streaking, and constant convergence drift. Control Modules also become flaky at well below this hour mark and should be replaced with a newer one. I think it's irresposible to tell the guy to dump another $1k in used tubes when you know nothing about the condition of the rest of the chassis.

gee thanks,hugs and kisses to you too. Curt and I have already given him the best advice possible, part it out and recoup as much money as you can.
