|
|
Hello,
I just picked up a used Marquee 8000 for cheap. It has been sitting in storage for quite some time.
At first, everything was going fine. According to the hours, it only has 180 total on it. I took of the lenses and the tubes look practically mint.
I put it back together and was going to do a quick set up. I noticed that for some reason, the blue gun had thick horizontal lines, in a pattern in it. The other colors were normal. Before I took the lenses off, the blue was fine. Don't see how taking the lenses off could have caused this.
I went to the projector initialization menu, and scrolled down to reset everything. I didn't press enter when all of a sudden, the pj shut off. There was the H.Fail led lit up. I couldn't get it to shut off, so I unplugged the power cord. When I turned it on, it would power up, then switch to standby, then on, then standby over and over. The crt's never come on during this process.
Now that's all it's doing. On/standby over.
Any ideas?

Ok this could be the classic" been sitting too long and all the boards need cleaning and reseating along with the chips on the CLM problem".
1) remove the HDM and then remove the daughter board on it and clean the contacts, there are also two chips on the daughter board clean those too.
2) then remove the CLM and clean the contacts on that and the contacts on the two Daughter boards(DPB and SWB) .
3) while the two boards are off the CLM get a chip remover tool and remove and clean all contacts on the CLM and the DPB. Use Caig cleaner and protectant available at radioshack. Make sure you do not mix up chips or their orientation in the chip holders.
4) clean the board entire surface with denatured Alcohol and a soft tooth brush.Let dry put it all back together .
5) remove the LVPS and clean the contacs on that as well along witht he HVPS.
Most of this should be done as preventive maintenence, i do it every 6 months along with some vacuming and some compressed air.

Thanks for the quick help.
I will head to Radio Shack and pick up those two items. I'll report back when I do all of that.

Will tv tuner spray work as well as Caig deoxit spray? I got it from Radio Shack. Hope it is okay.
Also, everything seems to be really clean in this projector. I cannot see any signs of corrosion/oxidation at all.
I did everything on the list above, but still having the H.Fail error. PJ goes on to standby over and over still.
Now what do I do?

Sounds like the H board has shorted out somehow. I've got spares..

it didn't, the lenses are not connected to the electronics like on a sony

well that's a f*ck-up, never unplug a locked up marquee.  It's possible you staretd with an intermittent H-board failure and then scrambled the CPU chip when you pulled the plug. For future reference, when a marquee locks-up take a paper clip and push the little recessed "re-set" button on the back.
You can try de-oxing everything, keep in mind that oxidation on a board is not seen by the naked eye, it's not like a corroded car battery. your talking about a very delicate 5 volt signal, .
If that doesn't do it I would send the HDM module and Control module to someone for testing. With tubes that minty it would be really be worth it to have a pro transplant them into a fully serviced 8500. Substantial perfromance and reliability gains to be had that way.

Pull hte H board and also the F board to see if the set will stay powered up. You won't get a pix with the H board pulled, but at least you can narrow down the problem.

Thanks everyone for the information. It never fails to amaze me that a 15 year old piece of electronics still has a bunch of people that care greatly about it. A refreshing change from the throw away society that we live in.
Reset button. Well, now I know.
I'll try to get a can of de-ox today and see if it works.
I like the transplant idea, but it might be out of my budget at this time.
Curt,
I pulled the H board and it still does the same thing. I then pulled the F board as well, and same thing. What does that mean?

Disconnect each neck board one at a time. Don't just remove the board from the CRT socket...it has to be completely disconnected. You can also combine removing the HV to each tube as you test it. Your choice.
Add this $0.02 opinion to the $86K the national debt clock says I owe. What the hell, I'm feeling generous. Make it an even ten cents.

Sorry, but what exactly are the neckboards again? It's been a while since I've owned a crt and I couldn't find it on Curt's site.
I did unplug all of the HV leads without doing the neckboards, but no change.
Do you think a 15 year old pj could have a dead battery? Would that be a possible issue? How do you take the battery off?

The neckboards are inside the metal cages at the end of each tube. You'll need to remove 2 small screws from the top of each cover. Tilt it out and toward the rear of the pj to remove it after removing the screws. Note that each cover has a grounding strap. Make sure the straps are reattached after you've finished testing. Make sure you're working on it with the power cord disconnected and the set has sat for half an hour or so after being de-energized.
I'm not a pro but I'm about 100% sure the battery wouldn't cause your problem. The battery only maintains any user setting changes. As far as I know it wouldn't cause the problem you're seeing. FYI, the battery is soldered on. You can test it with a DMM. I 'think' it's 3.6 volts but it will say on the battery.
I'm waiting for draganm, Mike Parker, or Tim to contribute as I'm curious what the problem is also.

the Marquee projector is still in production, well the 8110/8500/9500 anyway, they quit making the 8000 in 1995. we love these machines because they were designed to be repaired and run for 100k hours. 50k hours is quite common so far based on what people have found.

I'm assuming you mean the control module indicator lights are cycling from green to orange. sounds like a fault on the control module, or possibly the power rail from low voltage power supply is damaged. Hard to tell at this point, it could be a number of things tripping the CLM and keeping it down. What city-state are you in, maybe someone local can help out?

Tv Tuner spray cleaner is nto exactly the same. its more of a lubricant/cleaner for the old style turn knobs, your volume and channel changing. The Caig cleans better and it comes with a second protectant spray. At Radio Shack its not were the other cleaners are, it is usually located with the electronic parts and blank PCB boards. they don,t put it with the other stuff as they don,t want competition for their own cleaners.

I'm in Hawaii, so as always, not to many options locally.
I went back to radio shack and they didn't have Caig spray, but had a radio shack brand of electronics cleaner that removes oxidization. Still no go after cleaning/reseating the chips and boards.

Okay, something different happened. Up to this point I hadn't connected any source to the pj.
Finally I connected my PC to it via a vga to 5 bnc cable. When I did this, the machine doesn't keep going from on to standby. Instead, it instantly goes to H.Fail and stays on.
Next, I unplugged the H Board and powered it up again with the pc plugged in. The pj now stays on with no H.Fail light. Of course no crt's come on either.
I also unplugged the source from the pj and almost instantly it goes back to the on to standby cycle.
So why would plugging in a source affect anything? It sounds like the H board is definitely the problem, but why would plugging in a source make the difference I'm experiencing?
Edit: The pj will still cycle on and standby with the source plugged in sometimes, but after a few times it will stay on. If no source is plugged in, it will cycle endlessly.
Also, I noticed a pattern in the clicks. When it cycles on to standby, it clicks two times with a pause between both clicks. When it stays on, it clicks to times quickly, the after a two second pause or so, a third click happens and the pj then stays on, either with H.Fail with the H board plugged in or no error with the H Board unplugged.

the clicks are relays trying to sync to the scan rate i belive on the HDM, I wonder if its a sync issue? try disconecting the H and V sync cables and make sure that are connected properly and not to the wrong sync, the color codes are not alwast standard on those break out cables for H and V. swap them and try that first then remove them and see if it stays on with an h-fail still showing. if it doesn't stay on with the h and v disconnected it sounds like a H/V sync issue , but the experts would know best.
And also do as Jarmo saiys and test those fuses on the VIM the two green( 0 ohms) and the two 4.7ohms near the connector.

My parts machine was doing the same thing (this is the one DHL speared, dragged, dropped, etc). I replaced the F board and the clicking stopped...but I never did get anything but very faint light from the tubes...and that was with C&B at 100. I only know it was 100 because that's all I could barely see was the sliders for each.
I replaced every single board and PS from my working 8500 and could never get normal operation out of it. The only thing I could think of that I didn't do was try different tubes and/or the motherboard and back plane. But I wasn't about to tear the working one down that far.
