    LG 55LE5400 shows half splash screen then blank backlit screen half gray half black

    LG 55LE5400
    when initially turned on it shows the left half of the LG splash screen then fades to a blank (black) backlit screen which then eventually fades to a left-half gray, right half black backlit screen. no image is visible.

    its my friends tv and he said that when it failed "it had sound but no picture"

    i have not been able to switch the inputs in such a way to hear any sound. but as i am feeling around blind, i dont know if i am switching the inputs at all. with many tvs, pressing twice on input will switch you to the next input. but some tv's menu's require you to press other buttons to select the input from the menu which comes up, and then even press some other button to confirm the choice... which can be pretty hard [hard to justify the time spent to $ earned] to figure out when you cant see anything.

    i searched before posting and this tv's model didnt come up in the forum so i figured i'd create a new post and see what the people say.

    if i could actually change the input and hear some audio coming from the tv, as my friend claimed was the case, then i would still only know for sure that it was a problem either with the panel, the tcon, or the mainboard.

    anyway i took some pictures of the splash screen it shows, and the black/gray that it fades to eventually.

    im probly going to open the back and mess with the tcon cables and see what that does but i might not get to that tonight. i would appreciate your educated guesses as to what the problem is, purely from looking at the 2 pictures.
    thank you

    Ohh dear :L I would probably say bad lcd screen here. Seeing a similar issue on a vizo which I think had an Lg screen and it was a failed Lcd screen which is unfixable. You can try reseating the ribbon cables etc to see if anything helps.

      after messing with the tcon, disconnecting one side, then the other, i noticed some horizontal lines on the side which wasnt connected... which to me, can only mean panel damage.

        Sharp TFT-LCD Model No. LQ050Q5DR01 gray screen
        by Mad_Science
        I have a older eddy current tester made by Olympus that uses interchangeable TFT-LCD screens. I have two devices that each take the same removable screens. One is an Olympus NORTEC 200D+ and the other is an Olympus SONIC 1200M EMI. I have searched the internet high and low for service manuals for these units with no luck. Both these units were used extensively by the US military for NDT on airplanes. The detachable screen plugs into the base unit via a weird non standard VGA connector. Buttons on the removable display are used to power the units on. When the power button is pressed the unit makes...

        Samsung UE55JU6800K half screen dark
        by Chrissygizmo
        Hello everyone, I’ve just been given a Samsung UE55JU6800K smart tv as it had white spots on the screen due to the led lenses falling off. After refitting them & putting the tv back together I thought it was a nice easy fix for a free bedroom tv , then I tried it before screwing the back into place. I realised that the right side of the screen was darker than the other side, I removed the screen again as I thought the backlights had failed but they are fine.
        I put the screen back in place & turned it back on . The screen seemed to be ok again but different screens on the same...

        Macbook 2017 with touchbar (A1706) won't turn on after removing the screen
        by Ryan.man
        Hello everybody! Posting this in hopes somebody has some expertise that leads to a clear path of troubleshooting that saves me a lot of time!

        My macbook has the flex cable problem, the one that prevents the screen turning on. Ive been dealing with this for the last 3 years. Last year it went dead and I managed to fix it following youtube tutorials. But my fix wasnt the best, the problem returned a month later. This week, it went dead again. I again tried to fix it.

        This time the original cable broke too close to the screen, it can't be fixed without tearing the screen...

        LG 55UH6150- trouble powering up, then half lit screen (pictures!)
        by valvashon
        The 55" LG has been in the basement for a few months without being used. Turned it on yesterday, set came on as it should and showed a complete screen for about 5 seconds (was on a broadcast channel but no antenna was connected), then the screen went mostly dark with about 1/3 of the screen on the right lighting up with brighter lines in that lit part (sorry, no pictures of that). Power LED was cycling too, preventing the TV from fully powering up.
        Pulled the back off, all boards looked OK. Pulled the LED connector, turned the set on to see if it would power up but I don't belive it...

        TD Systems K50DLG12US half black and half white screen
        by Raulnn
        good night! I have this screen that looks half black and half white. the tcon gives a low vgh value (5-6v). the rest seem fine. I first removed the flex from one half of the panel and then the other. Removing the left, vgh increases it to 25-26v. I think the problem is in that area, but there are not many elements on the integrated controller board. there are no shorted capacitors. could they be a cof? Some help?

        By the way, now the entire screen is black. Maybe some flex was not connected correctly... I have exchanged the flex and there are no variations, I don't think they are the...
