    On pretty old sets--especially from a smokers house--the backlight and diffuser becomes dull and yellow/faded.
    --The tubes themselves also start to show more yellow light when very old....

    Ive seen a couple of LCD like this, and changed the backlight on one--the difference is staggering!

      Hi Alastair,

      Thanks for the reply. As I remember it turned yellow in just a day. It is working fine on the previous night and the next day when i turn on...the picture becomes yellowish/dark.
      So is the culprit is the backlight module?

      BTW, no smoker here..hehehe..

      Thanks.

        Philips 37pfl560: Yellow picture
        by madyoyo
        HI.

        I have a weird problem with an old Philips 37pfl560 TV i put out of storage: the picture have a noticeable yellow hue, and its not caused by the settings (did a factory reset). I've never seen this before. I will try to get a photo with a real camera, with my phone its hard to see because of automatic white balance, but in real live the whites are really yellow.

        Anyone have an idea of what can cause this? Can CCFL tubes get "warmer" with time? This tv have several analog inputs,so its nice for retrogaming....

        T-con suspect issue. Both ribbon cables no picture. One ribbon cable ok. (58pus8545)
        by Tr0ll
        Hi guys! I realized you have a lot of knowledge here so i am hoping you could point me in right direction with my odd issue.

        The Tv is a Philips 58PUS8545/12, it had no picture but working backlights.

        Original T-con:
        Opened the Tv and tested to unplug one ribbon cable at a time. With this test i could see that i got fine picture on both halves as long as there was only one ribbon cable connected, with two connected picture were gone.

        First replacement T-con:

        I thought it might be t-con and ordered new t-con from china(supposedly tested)...

        SAMSUNG UN55KS9000F picture fades then distorts into vertical lines after 20 seconds
        by JJAAMM
        This was my main TV for the last 6 years. I'm not inclined to throw out a $2600 TV so quickly so I'm trying to investigate the issue.

        Problem
        TV was disconnected from power for 6 months during construction. When I plugged it yesterday picture was fine, after 30 seconds it dimmed then started developing horizontal lines, picture then starts to ghost vertically until it degrades into vertical streaks. TV always displays a perfect picture when cold. I can unplug TV for 5 minutes and plug it back in and picture is restored for 20 seconds. I can also keep it in standby mode...

        LG 43UK6200PLA - yellowish picture
        by tomislav4545
        Hi everyone. I have LG 43UK6200PLA which stopped showing picture a while ago. The main board is model EAX67872805. It has sound and backlight. I tested the two ribbon cables on the tcon board and concluded that one of them is faulty. I taped pins 1-12 and now the picture is there and there are no glitchy lines. The problem is it switches from normal color to yellowish color repeatedly. In the attached photos the first one is normal color and the second one is changed color. Any suggestion is welcome.

        Thank you all....

        Hi, I have a Samsung UE50TU with:

        - when it arrived, it had a picture for a few seconds
        - it keeps rebooting

        - without cable between mainboard and lcd panel, it does not reboot (but obviously i have no picture)
        - when i try a tape fix, its keeps rebooting, unless I tape off pin 1 (the innermost pin). In that case it does not reboot but I have no picture.

        - without cable between mainboard and lcd panel and with a jumpered...
