Z3 - light bands on top & bottom of screen

[Plamff]

Hello all,

I have had a Sanyo Z3 for a month or so now.

I'm very pleased with it - but have noticed a strange thing. At the top and bottom of the picture there is a band 4-5 pixels wide that is a bit lighter than the rest of the image. I initially suspected a panel alignment problem, but the R G and B panels seem to be well aligned.

It disappears on darker images but is worst on light coloured / panning views.
It's not the end of the world.....but you know how it is...once you notice these damn things.

Any advice appreciated

It may be "hidden" extra info eg subtitles / closed captions etc transgressing onto the visible pic. Is there an overscan option on the Z3 which will allow you to "nip it off"...PJ

Not sure. Will check it out if I can do this.

Many thanks

Possibly rear mirrow alignment, try inputting a white signal, you should be able to check for uniformity, if still have shading, get it fixed under warranty

Many thanks, will try that

I tried inputting a white signal and cannot see the lightening.

Also, I tried red, green and blue signals and they all seem OK.

After extensive scrutiny -
You can't see it on v. dark or v. light images, only medium images (blue skies for instance).

The topmost and bottommost 2-3 rows of pixels are lighter than they should be and the next 2-3 rows pixels inside are slightly darker.

This happens on every screen mode - full / widescreen etc.

I phoned Sanyo technical helpline - the chap told me it was dust on the panels and suggested I clean them with the puffer. Didn't have a lot of confidence in that advice but did it anyway - no change.

Amusingly, I was getting obsessed with the mild VB until I saw the light bands at the top and bottom of the picture. Now I don't notice the VB.

Perhaps, I've got a compulsive/obsessive personality

I think its only natural to notice every fault when you first buy something - especially if you read this forum

I'm just getting on with enjoying mine now - even the dead pixel isn't bothering me at all - use it, enjoy it, then upgrade a year later - job done!

good advice.
