Maybe a problem with Z2

cliocarl · 06-06-2004, 11:31 PM

Hey guys,

just set up me Z2 watched a few clips from a few films to show my m&d then me sis wanted me to put on Save the Last Dance, so I did, shifted the lens as you can, adjusted the keystone and noticed a sort of green blur slightly thick vertical line on about a quarter of the screen height size.

It only occured on certain scenes like one minute you could see it the next minute you couldnt.

Does anyone know what this may be and how I may fix it?

Thanks, Carl

Can you reproduce it reliably by playing those scenes? Or does it just appear randomly?

at work at the moment but will test it again wen i get home with different disc.

However I think it comes on then off within seconds. On the dark scenes its not there, will full check and take pics tonight.

Why what you thinking it could be?

buns · 07-06-2004, 1:25 PM

I wasnt thinking so much at what it is, rather what it isnt..... first trick is trying to find what component the problem lies in. Have you tried the same signal (same output/resolution etc) on an alternative display?

gonna try it all tonight

Check out this picture from a scene on disc one of Band of Brothers, the dotty thing is the side of a warship in the film.

You cant see it by looking at the thumbnail which is like looking at the screen from 2.5m away, but when you get closer - ie open up the attachment into big JPEG you can see next to it it the problem!

Anyone no what this may be?

oh yeah.... looks very weird and i cant say I have seen it before. Did you get a chance to try the source elsewhere or another source on the Z2?

As the previous owner of the Z2, I was obviously horrified when Carl stated what he had experienced. What I can add to this thread though is the experiences I had with the PJ, to help us shorten the potential list of problems.

I usually watched the PJ picture at about 8ft across & only 8ft away......I know, breaks the 1.5x rule. From this distance I used to pick up the screen door effect, so would have definitely seen the green band shown in the picture. I mostly used an ARCAM DV89 via component & neevr experienced this problem.

From this we can deduce it's either a source problem (eg. DVD player) or something has happened to the PJ in transit from when Carl demo'd the PJ at my place to getting it home. Now it was placed in its polysterene packaging & I know Carl would have driven carefully home, so any jolts would have been minor. Carl, it's probably worth mentioning in detail ref keystone change and how it wasn't there before, but was after. Might help others solve the problem.

Is another option to identify problem to keep changing the background colour of PJ screen, with no DVD playing. Anybody any advice on the colour that would show the green band up ? If it doesn't show, then it points to DVD player as problem. If it does show then it points to the PJ. Would others agree ? I actually did this exercise to verify no dead pixels, on top of normal visuals of films etc.

I'll contact previous owners to see if they have any opinions.

It's not just a smudge on the lens is it ? Looks a little like it might be a smear of grease from a finger touching the lens.

I could also point out that the pattern isnt vertical..... not your problem but you might look to adjust how it is sitting.

Just before I start, buns thanks for your kind responses and to everyone else, obviously I am quite scared about this issue as I have just shelled out most of my savings

The image just looks slanted as thats my camera skills

Right,

Tonight I have used the DVI input from my PC and the problem is still there so it definitely is the projector.

So when the problem was on screen I paused the source and then adjusted the keystone correction. The problem moved up and down when adjusting the keystone in different directions. Sometimes the problem is hardly noticable when keystone is in a certain place. So basically this problem is hard to spot as when engrossed in the main picture/film, the problem only occurs with some colours, those colours occur in some scenes (like shown in the picture) and when keystoned is less obvious/more obvious - when fully keystoned to a V shape it is one whole line!!!!!!!

So I am now gutted.

buns · 08-06-2004, 7:03 PM

so can you actually get rid of it with keysone? You make it sound a bit like a processing error

cliocarl · 08-06-2004, 7:06 PM

No you cant get rid of it with keystone, when you adjust the keystone that blur seen above moves up or down depending on keystone direction.

Sometimes it doubles, one below one above, sometimes it tripples 3 in a row vertically, and then when totally to the 'V' shape picture it is a full line!

When in a neatly keystone picture it is rarely noticable and difficult to see from a distance. However noticable when sitting half a metre away.

It probably is worth talking to sanyo themselves now..... the machine must still be under warranty

Carl,

I had a problem with my first Z2 which was a green line appearing in the far left and far right columns. I advised Ivojo and they arranged, with Sanyo, to swap the machine out for a new one. No problems with the second one :-)

I would suggest yourself or Dave(whoever has the recsipt to show proof of purchase) to get back in touch with the supplier and get a new pj shipped out.

Cheers,

Steve
