|
|
What boards are to be changed to make it less drifting? My blue, but by far my red, is drifting like mad for at least an hour or more. I solve it by quickly realign it when I first fire it up; and then some more times every 15 minutes or so. Bottom line I'm fed up with it. Money is tied up elsewhere but what free advice you got for me? 
Thanks in advance!

Doing the Dragan HD mods will most likely cure it. There's no good answer here, as several boards can affect drifting. Convergence, vertical, astig and H board can all do it.

He's good at that, but it'll have to wait. Sending boards to him would be insanely expensive so I have to do this on my own. Somehow.

Just do the mods yourself.

I want to man, but without a de-soldering iron, it's very difficult to make it right.

Even when he could buy the required tools for about $50

I was thinking an old 280Z with some slicks on the back would be good for drifting.

Not how your suppose to do this.
Fist What I have found is to let pj warm up for an hour with the LC housings loose so they can move with the heat.
Then when the PJ is warmed up try to use a mechanical movement of the LC Chambers/Lenses to align the
grid. Also make sure the Blue and red grids are centered first before moving the housings, then tighten down the LC housings really well. Now do the convergence.
You then just let the PJ warm up for a while before watching. Converging cold is counter productive, you always do a set up with the PJ when the Temp stabilizes. an hour is the best reference point. Color calibration should also be done with this time period.

I agree fully with Nash
Both my marquee and my dwin holds the convergence better if it is done when the set is warmed up first
Main thing is getting the tube toe in right FIRST go into the convergence menu and reset it then do what Nash said and then do the convergence afterwards
It's saved me a lot of trouble in the long run

Im'm interested in that, too. But does anyone know which projector we're talking about?
Mentioning the dragan mods means that it should be a marquee?
Ok, please tell me.

Proper mechanical set up is critical. I introduced an additional step to mechanical set up that helps to ensure optimal alignment which leads to minimal if any drift. Initially the set up guide asks you to center R/B raster and then align the guns at the edges of the green grid. The problem is that once you fully converge the image the R and B raster's are then shifted off center on the tube face. At this point you need to re-center the R/B raster's and then perform another physical alignment of the R/B to G.
Nash is dead on about needing to wait one hour for the PJ to warm up.

Good stuff there, from all of you. I do the normal steps, like described, but haven't had the patience to wait a full hour and than align. It's more like 40 minutes. But I'm sure there are steps that needs some closer attention the next time around, and will do it all over again soon when I got some money to bail out the refurbished blue tube from the post office.
And also, my pj is not to far forward as I mentioned in some other thread. I deducted another 20 points from HTOT and the image fits the screen now. But there are a yellowish tone from top to bottom and a foot wide on the left side still that just wont leave. If it still there, after the blue tube has been changed, I'll post an image to show you. It wasn't there before when I had it set up with long retrace.

Also if you need help after letting the set warm up hit the help button and select guided mechinacal setup and the projector will walk you through the whole process
I used it when I first set up my Ecp but haven't had to use it with my marquee(dwin doesn't have it)

Yes, it's a Marquee, but this involves any projector. I assume Barco or any other brand drifts to a certain degree also. In fact, I'll wait 90 minutes next time and do it all over again from scratch.
