    Exclamation Image color tone changes when watching from USB

    I have a 42PFL4208M/08, bought in august last year. Since then I've had a pretty annoying issue when watching videos from USB (I'm actually on USB 3.0 hard drive), the color tone of the image changes/varies with every scene. It goes from too dark to a desaturated image, from greenish tone to a red tone, as if it would adapt to the images playing. I've deactivated every coloring or image optimizing option, and still nothing. FW is updated to the last version (june 2014). Has anyone had this problem? Does anyone know how to solve it?

    Thanks in advance!

    Hi mayte,

    Do you mean that Ambilight colour tone changes or the picture of the TV?

    Please clarify.

    Also, does this only happen on USB source? If yes, does it happen with different file types as well?

    Best regards,

    Hello Ina,

    Thanks for your reply. My TV model doesn't have Ambilight, so it's the picture showing on the TV that's constantly changing color tone with every image, it's subtle most of the times but annoying non the less. It does happen only when playing files from USB, and as I quickly checked through the file I remember I saw this happening, they're all "mp4".
    In fact, when playing .mp4 files, I can see two lines on each border side (one to the left, and the other to the right) that are slightly lighter or darker than the rest of the screen. When the scene changes and the tone changes back to a darker shade these sidelines disappear. I don't see these lines when playing files like .avi or .mkv
    I'm attaching two images, same video, taken a couple of second apart while playing the file.
    Thanks in advance!
