In researching G2 adjustment techniques, I found that if the PJ displays a spot on the screen for a split second after you turn it off, there is a problem.


My 1031Q seems to exhibit this behavior. When I turn it off, it goes black and then a little less than a second later it displays a big round spot (it's about 1 1/2 to 2 feet in diameter on an 85" wide screen) in the center of the screen for a fraction of a second. The flash isn't horrendously bright - about the same brightness as the windows desktop.


It's been doing this since I got it 1 1/2 weeks ago, but I didn't think anything of it until I saw it mentioned in a post on this forum.


- Is this a real problem?

- If so what is the cause and how can I fix it?


If it's a component going bad I should be able to get a replacement from Hammerhead since I just got the projector from them.


Thanks,


Larry

The reason can be that someone that sold you that PJ wanted to get out more brightness and contrast , so the voltage on crt guns are set to high.

That's odd. When I first got mine going a month or so ago, I think it was Curt who said that was normal for a 1031Q.


Not to dis anyone, but from what I've been told, they all do it briefly at shut down.

HELLO!


Thats perfectly normal with this model projector!!


If you however get a VPR722 controler it will turn off more "softly" Mine is in perfect working order and it did the exact same thing at shut down with out the controler. In Fact if you turn off the pJ with the front switch still powered on and keep the 120 volt outlet hot and turn off the unit with the rear power switch I think it will turn off softer as well. I used to leave my units switches on and turn it on and off with my racks power conditioner simply but killing the power feeding the unit. I would flash a huge white round circle. There would be no after spots or little dot on the screen THIS is whats the BAD THING. If you turn off your projector and it looks like grandmas old a TV when it turns off. You know the little white dot that fades off, that will eventually burn in the tube if your unit does that.


What you describe is normal operation with out the VRP 722. I however grabbed a VPR 722 and 14 pin control cable and it makes a huge differance in shut down and how well the unit stays converged. It seems thr convergence drift is very minimal now with the softer shut down as well.


I hate to say it but it may be best to turn off these units with the rear switch rather then a "remote" power switch other then the SONY controlers. It may be possible to change the rear switch to a 12V realy and remotely control it from the switched outlet on a receiver or preamp.

That would make a good project:)

Vic's right,


The spot kill on these thing's are a little sloppy. You really should be turning it off from the rear power switch though. Killing power to ANY CRT PJ is awfully hard on it and should be avoided if possible.

Great! I'm glad to hear it's normal on the 1031. After wrestling with the ghosting issue so intensely for the last week, I really wasn't in the mood for another problem.


Thanks,

What is the purpose of the PVR722, and how does it help the unit stay converged?
