having tried factory and service menu No14 and 65 unsuccesfully cheers to whoever it was that recomended factory 25 and 26 settings
a slight tweak on 26 did it for me
seems your choices are either white or grey vb and you have to settle for something in between
looks like 25 and 26 give you finer adjustments than the others
dont think will ever cure completely but certainly accebtable now
hope this helps others

i hadnt heard about using this..... those are color/tint type adjustments..... did you check things with avia once you were done in case you shifted things?

As far as i can see, the bands literally are bands of different colors, i actually thought they were red and green bands..... but i guess they could be of the same color but different strengths....

glad its better

i changed my no14 setting from a low 76 too about 88 and vb has nearly completely gone.
Buns what are all your factory settings now, i mean the one where 14 is to do with vb, as you seem to have pretty much got the best pq from yours.
if you can list them that would be much appreciated
cheers

press the buttons on the actual projector, i couldn't do it with the remote. I think it is "input" and "select", hold these together at the same time. Then it will come up with service menu, you can scroll down to number 14 and a figure of about 80-90 was meant too lessen vb, be careful though and write down original numbers.use the right and left directions too increase and decrease the value

factory is the input and select, input and menu is service.

Fred,

I havent altered my factory settings, it seemed to alter my other calibrations, besides, the banding isnt easily visible anyhow.

Service is sitting at

61
50
40
0
0
0
530
380
390
171
138
133
83

82

note that this is dvi pc digital and that my contrast settings are well down and brightness well up. Also note that this is a PAL calibration using the german disc.

I could swear there was no VB 'out the box' but now after about 30 hrs use i can see it. Allthough not bad enough to ruin my viewing.. it is visible.

Has this happened to anyone else?

PS. I have only tweaked a couple of settings in the main menu.

Well, certainly I found vb to be less noticeable out of the box. One reason for that, I think, is because vb is more noticeable on a lighter picture so when (if) you umph up the gamma you notice it more. Also, when you first watch I think you tend to focus in on issues of contrast, brightness, sharpness etc leaving vb to become more of a “background” issue.

i too noticed that out of the box the vb was not visible, but after around 25 - 35 hours use it became very very apparent.

a little tweak has done the trick.

i used the pc background via dvi, the light blue seems to show up the vb a treat, you can then use the service menu to adjust them away.

sorry guys have to take back what i said
vb still there!
was using different colour screens on desktop and thought id got rid of it
and seems to be getting worse with more use!
hope a fix comes soon

[buns]

i saw it stated on avs somewhere that sanyo had said panel voltage needed adjusted..... no one will confirm a source though, unsurprising since sanyo i spoke to did their best to deny service existance!

You want my bet..... calibrate as well as you can and forget about it, aint gonna be no fixes

Ineresting you should say this... the lines I see are very light grey in colour. They are static and about an inch or so apart and only visible on large areas of blue/ grey sky for example.

Are we talking aout the same thing?

Cheers,

Chipster.

Well if your bands are grey.... what are the other bands? Saying mine are colors, this is when i look at a grey screen. So by that you could probably say they are grey. However, on close inspection, one set of the bands looks redish, the other blue/greenish.

Buns,
I see no hint of red or grey bands on a white screen. I can only discribe them as faint grey/ whiteish de-focused smeary thin lines only visible on large skyline or landsape scenes.

Have not had a chance to try DVI direct, but component prog scan and VGA to DVI give exactly the same resulting lines, albeit with different colour rendition in the pic itself.

It would be interesting to see how others discribe VB.

Chipster.

[buns]

well mine are def a chroma difference between the bands, not a luminance....
