    My almost 2 year old AE100 (500 hours, eco mode) is nearing its waranty expiration and is exhibiting some very minor colour staining at the top left and bottom right of the screen. This is only noticably during some dark/greyscale scenes, for example on black and white films. It is not noticable on any of the service menu test patterns at all. My questions are these:
    1 - What exactly is this?
    2 - Is it likely to get worse?
    3 - Will panasonic consider this a fault and fix under warranty?
    4 - Will it seriously effect the already bad resell value of this machine?

    Any help will be greatfully received.

    Azzo.

    Sounds like a colour uniformity problem. Had the same with mine. Panasonic took it back (postage paid) and fixed it under warranty.

    It has come back again (not as bad). But will get it done under my extended warranty when the problem gates more noticeable. Apparantly it's 'fixed' using some sort of adjustment software, so the engineer told me.

    It's not an uncommon problem with LCD machines.

    Panny service number is 08709 070909.

    Chris, thanx for the reply.
    Is it possible to tell me how bad the problem was and whether you had to 'persuade' panasonic to acknowledge it as problem.
    Also, how long did they take to fix it.
    It seams strange that they could fix it with a software tweak. This looks like it could good be a problem with the lcd panels or prism? (well thats what I'm guessing from reading the forums here?

    I had 2 patches - one on either side of the screen. Panasonic took it ib without any fuss. Took about a week or so to turn it around which I thought was pretty good.

    500hrs in 2 years!!!! I did 3500 on my old ae100 in 11 months. If I add the hours on my ae300 of 2500 that means I've done 6000hrs in the time it took you to do 500!! :D

    Do you only take it out of its box on Bank Holidays!! :D

    Look calibos its the quality of the viewing, not the quantity.
    When I said 500 hrs, is that out of 5000 or 2000. (The 500 is on the options menu)
