    No red

    LG 42LC4R -2007 model.
    Came in with no power and 5 bad caps, which I replaced and it came on nicely, except that there is no red colour - very weak picture with a little bit of red if Standard setting is selected.
    On Standard and/or Dynamic is very weak.
    Only under "User 1" and/or 2 I get a bright picture, but no red.

    Re: No red

    Check LVDS cable is fully seated. Try full factory reset. Check Red Gain and Red Offset in the service menu, if available.
    Please do not PM me with questions! Questions via PM will not be answered. Post on the forums instead!
    For service manual, schematic, boardview (board view), datasheet, cad - use our search.

      Re: No red

      Thanks a lot for those suggestions.
      LVDS cable was carefully checked as soon as I noticed the fault and it was firmly plugged in; even shook it a little to make sure. It's not it.
      Also the resetting in the menu doesn't help a thing.
      Since there is a minimal amount of red when on dynamic picture [only gives a dark picture], but noting on User, I'm puzzled.

        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...

        Samsung TV model UE50TU: rebooting, backlight, sound, but no picture
        by TR103
        Hi, I have a Samsung UE50TU with:
        - sound and backlight, but no picture
        - when it arrived, it had a picture for a few seconds
        - it keeps rebooting
        - without ribbon cable between the two panel boards, it does not reboot but I have no picture
        - 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...

        Samsung UN60EH6000F Black Screen, Backlight and Sound Good. Power Cycle Returns Picture
        by Mgiffune
        I have a 60 inch Samsung UN60EH6000F flatscreen TV. The screen went black a few months ago Sound is good, backlight is good, no menu. I replaced the TCon board with a used board purchased from Ebay. It worked fine for a 3-4 months, then the screen started β€˜fading' back. Once again, sound is good, backlight is good, no menu. However, this time the picture looks fine for about 10-15 minutes, then fades back. If I power cycle the TV, the display reappears, for another 10-15 minutes, then fades black again. Repeatable ever time.

        I ordered a supposedly β€˜new' Tcon board this time, and
        ...

        Issue with picture quality of Sony bravia TV
        by CyberPhoenix
        Hello, Last week I bought the 50" Sony X80j tv everything was working fine, untill I plugged the tv in a ups power supply 650va the tv remote control became unresponsive and the TV became laggy after a while the picture quality isn't the same as before the tv seems less brighter and the picture is somehow blurry, people's faces don't look as natural as before, there is a mini orange-pink tint to the edge of people's faces especially in NETFLIX Dolby Vision like in One Piece ep1 Alvida skin tone, my intention was to protect the tv but something went wrong I checked the ups with a multimeter,...
