Another ebay horror story.


Picked up a 1031Q cheap on ebay. photo showed it working... unpacked it and plugged it in. No go. The fans spin the convegence board lights up. But nothing from the tubes. When you click the power on and off they momentarilly illuminate. But I can't get them to project the test image.


Any ideas?

If it doesn't project the test image (convergence grid) then i don't think it'll work at all...

Try connecting up a composite source and switching it to LINE at the back.


My sympathies.

 

[eschlene]

yeah... tried that. sent a composite video signal into it and switched it to line but no joy.


the tubes crackle when they power up, but no image.


I don't get it. Thing is they look good, too. I checked 'em out putting a flashlight to the tube and I don't see any burns or wear.


oh well. Anyone else have any suggestions... I'd love not to own an anchor.

Eric ,

-- you need to check all the connections inside the unit after leaving it UNPLUGGED for a couple days [ these units have LETHAL current flowing through them ] . It is possible that something was Jolted lose during shipping . The tubes are probably fine as a bad tube will not cause the other tubes to not light up and the odds of all 3 tubes being shot are Slim . Keep Positive and you'll get it going .

Have you checked that the three RGB switches on the convergence board are turned on? They are right in front of the convergence pots if you face the tubes from the back of the unit. Worth a shot. Once I was converging and switched them all off and put the cover on before switching them all back on. I was stumpted for about 10 minutes.

Great. I'm feeling better about this once I hear from some of you that these things get 'loose' in transit.


Is there an easy diagram or explanation to the fastest way to break one of these down? I've taken the cover off and the arched bracket assembly that the front grill and speakers are attached to. It looks like there are hinges on the top to offer access to the cards below.


If any of you can put it into words or have an illustration on how it disassembles most easily. It would be great!


Back when I tore down my Jeep and rebuilt it...

I spent more time on learning curve stuff, figuring out what disassembles and where, than I did on actually fixing what was wrong!


Thanks all!!!

If worst comes to worst you might be able to get some of your money back by selling the CRT's and lense assemblys.


Let us know what happens. If the CRT DIP switches are turned off If I dont think the tubes will "flash" when you turn off the power.


That, so you know is fine when you turn off the unit without the VPR722 controler the tubes will flash and project a huge white circle on the screen.

I got an incredible deal on a unit just like yours- with the exact same problem! It eventually quit powering up altogether. I bought another 1031q that works well for less than I figured it would cost to fix the first, but the tubes and lenses aren't quite as nice as on the dead one. I'm going to swap lenses and the blue tube. Then I figure I have a green and a red waiting when these go (which, eventually they will) plus plenty of backup parts!! In other words, if you can afford to spend some more money you might be well-off to keep the spare pj for parts, especially if the tubes are good!

I AM SO PUMPED RIGHT NOW!!! Check it out!!!!

woo woo! Been talking with several of you, especially Curt Palme. (Big thanks for your help, Curt!)


Anyway, I'm not snarfing popcorn on the couch, but the boat anchor has a new heartbeat. As I worked my way through the projector under Curt's tutilage, I discovered the tubes started to flash when I touched certain parts of the convergence board. The more I tweeked around, the closer I got to being able to keep em on. It turns out the 'lip' on the back of the aluminium 'lid' was bent in just a hair, causing contact somewhere on the board. this thing...

So I bent it out a bit and the tubes are on like there were never a problem.


Now it's down to me putting the lenses back in tomorrow and getting the image converged.


I'm sure I'll have more questions. For example, she runs fine without the fans. Can I leave them off safely? I know some of you prefer to not have the extra noise. I'd rather not hear the fans myself.


I can't say enough how much I appreciate you all for helping me get started in this hobby.


I thought you might like to see what the tubes looked like "off" here's a pix.

The photo shows more reflection off the glass than anything else. When you look close, there's a very faint wear mark on the blue tube. But other than that, I can't see any other wear or burns. What do y'all think? These tubes have a decent amount of time left on them?


Of course, the exterior covers were all pretty much toast. The tube 'grill' is all busted up. If anyone has any spare case parts, please let me know. I'm debating whether I want to find new cover parts or just build a custom cabinet for it out of oak once I get it set up and working.


Thanks again to everyone. I've found a set up guide online at projectorspecs. I think that will see me through basic convergence. I bet I'm going to have more questions for 'ye masters' tho.

sorry about those urls. you'll have to copy and paste them into your address bar. tripod wants to dork with them if you right-click and open into a new window.


sorry -e

Great! Welcome to the club! The 1031Q is a sweet pj! Happy converging!
