    LG RZ-26LZ50 green lines problem

    Hello all,

    I've been searching the net for a possible solution to a problem with an LCD tv my dad picked up. I didn't find the solution, but i found the exact same case in some youtube videos. I'm hoping someone here can take a quick look-see and instantly figure out what it's all about :P the make and model is LG RZ-26LZ50.

    this tv in the video probably has some signal trouble (which mine doesn't) as well as the green lines thing. basically, on my TV, the image is ok but after a while the green lines appear as they do in this video. i tried asking on two youtube videos if they managed to fix the TVs, but i got no response.. also i tried searching this forum and several others for the same model, but i got no results.

    here is another issue i have with the same TV. when it's working ok, the picture has some light jitter. i also tried searching for this symptom but no luck so far. here on this next youtube video dealing with the same TV, the blue rectangle also has the same jitter.

    maybe someone has seen stuff like this already on another TV set? it would be really swell if you'd share your experience my dad would appreciate it very much.

    ps. maybe it's important to note that when my dad got the tv, the picture was really messed up. totally distorted and jumping around, like a scrambled TV channel. He managed to fix it by changing one capacitor and it was working ok until the green lines start showing. i'm not sure, but i think that sometimes it works more than an hour totally normal until the lines appear.

    Solution is to replace two 47 uF SMD capacitors just above center the center of main PCB near 1.8 V stabilizer, I don't know position number, but two above each other

      This is old post, but just minutes ago have repaired LG 30LZ50 LCD TV.

        Old post, yes! But just want to thank rjndebruyn and lin4sm for these posts above. With instructions I fixed LG-RZ26LZ50, which had green lines and wobbly picture at start. Fixing is just replacing those two capacitors (C566 and C503) from mainboard. Here's a quick video or more or less it is a slideshow...
