    Backlight Problem

    I just bought a brand new LCD 55" Philips TV (55PFL8008) and the backlight bleeding problem is present. It is a problem in the bottom half of the screen and the top right and it has been getting progressively worse over the last few weeks. The bleeding is patchy but getting worse and keeping the tv on for long periods of time does not resolve the problem. Can anything be done via software to repair or do I have to take it to a service dealer for warranty repair?

    Hello Nickdak,

    Overall this is a issue that is in every panel. Depending on the amout you can get a service in warranty. I suggest you call your service center to check this. Make a clear picture of the backlite bleeding, they will probably ask for it.

    KR,
    Evil

    Evil, thanks for the response.

    The set is only a few months old so I called Philips who picked it up for investigation. However, I currently live and work in Moscow and the customer service that I received is dreadful. They claim that they took it to a service center who undertook tests (they won't tell me what type of testing) and the tests showed that the tv is fine. I pushed back and they said that I have to receive the tv back and then resubmit it again under warranty and they will take it a second/different repair center for investigation.

    I have identified that the bleeding is only evidence when I switch the profile to ISF Day or Night. I have attached some photos showing the bleed.

    Is this normal/acceptable bleed or is it a sign of a fault tv? I would appreciate any feedback as I am at my wit's end and I have hit a wall with Philips Russia.

    Backlight bleed is very common problem on edge-lit lcd tv:s. Most of the manufacturers won't replace your panel, if it isn't _really_ bad. Retailers however often are willing to make a deal that you can swap the product within time x if backlight bleed bothers you, you just have to remember to ask it - but of course that ship has sailed in this case.

    I can't see you attachments because they are still pending approval from the moderators.

    Also, there is the setting "Dynamic Backlight / Contrast" which is enabled on all the other presets except for the ISF-settings. It dims the backlight down on dark scenery, which improves the "blackness" of image, when needed. Also hiding the backlight bleed. I suggest that you try to set it to "standard" setting with the ISF-preset and see how you like it.

    Hi evil and antti-la,

    Many thanks to both of you for responding.

    Evil, hopefully the pictures will be approved by the moderator soon as I would appreciate your feedback.

    Antti-la, I will try adjusting the settings as you suggest and let you know how it goes.

    Thanks again

    No problem. I saw your pictures now. Seems pretty bad as you said though.

    I would suggest that you try these settings, from this topic. 8xx8 series recommended settings thread!

    But with the difference: Dynamic Backlight set to either Standard or Best picture. It just might fix your bleeding issues.

    Hey all,

    This is a thing called clouding. You should send this pictures to your service provider in your country. They can see if this is within specifications of the panel or that this should be send to repair.

    To me it seems a bit too much to be within specs, but im no expert.

    Good luck

    Regards,
    Evil

    Thanks to both of you for your responses. I will try out antti-la's suggested settings and pursue Philips at the same time.

    I will let you know how it goes.
