    samsung LE46A558P3F weird image quality and vertical lines.

    hi, i have this tv that show exactly same problem as this one on that video:

    https://www.youtube.com/watch?v=MW3x6eGT_Yo

    and also menu popup start to flicker, plus one side get almost all white.

    and like this dude problem too like tv get white on some corner and so on.

    https://www.badcaps.net/forum/showthread.php?t=41381

    board is the usual and well popular: BN41-00974B

    is that problem as-15f related , or are the ribbon cable that connect t-con to tv?

    on that youtube video, someone talk about y axis driver problem... , but as i have no experience with tv, dunno what to do except change as15f

    The problem shown is for a plasma display, so it would be rare for your LCD to show these symptoms, are you sure?
    Or is it more like THIS:

      tnx for reply. yes difect is a bit different. today for example screen become almost all white. i changed now as15f with a new one and problem remain for the first 5-6 second when start tv. after that time tv works very fine

      must be some capacitors related ?

        Sounds like a panel tab bond failure, non repairable and will only get worse... very common on Samsung sets unfortunately.

          looking better, tv seems to start just fine and after 10 seconds , color and quality get worse.

          ill make a video later with an hdmi source.

            here is the video, hope that it's not the lcd but some electronic fail.

                  Unfortunately looks like a defective LCD panel to me...

                    up the lcd, there is a screw, if i touch it i make lcd turn brighter or sometimes that problem get less worst.

                    edit: i did soem other test. that crew is just the bright control so nor problem with that. but i tried disconnect 1 by one t-con cable to lcd and still the same, then on the t-con if i put a finger on one chip thermal pad, i can hear a heavy noise that ir produce. so can it be a bad t-con or that king of problem just lies to a bad lcd panel ?

                    dunno if i got some problem with batteries, but when tv goes almost all white, it become also unresponsive to remote control pushing.

                    can i try this to check better?

                      update: today ive disassembled lcd and even if i touch lcd ribbon cable, nothing happen, so as tom66 said i suppose it's lcd 100% as also t-con make some noise and if i disconnect ribbon from t-con to lcd that noise disappear

                      im going to sell all parts for spare.
                      is t-con ok or it can get damage too because dunno if selling it is ok or not..
