    KUBO K1249VTSTUHD (49" ultra 4K Smart TV): Screen Problem

    Hello,

    I need help to dispel some doubts and try to reach the correct solution (if there is any...) to the malfunction.

    the screen has red blinking shadows/outlines, duplicates images, characters. this anomaly crosses all image sources: HDMI, SCART, VGA, channel tuning...

    I can't find technical information about it. This is a white brand, I think it is produced by Vestel (Turkey).

    I can perform multimeter measurements (to dispel some doubts), but I don't have an oscilloscope, and I don't have technical skills to perform component exchange/soldering. There is also no store to perform this kind of service nearby.

    SO, which PCB do i need to change? (if it's worth it).

    where can i find the replacement parts in Europe?

    Here are the references found inside:

    PSU:
    VESTEL 17IPS72
    Part Number (SKU) 23332051
    PCB corner 190216R3A

    other info in white label: 23342328, 23333030

    COF IC & PCB:

    info in metal Back Panel chassis

      Pictures of the problem would help.
      I assume no responsibility for any stupid suggestions I might post.

          Hi,

          I have already added two winrar files with the problem videos. can't you open it?

          anyway i have now added a picture of the problem "tunning menu". however, the picture does not elucidate the real problem, as it is not a static problem.

          thanks

              Looks like timing problem. You've cleaned and reseated lvds cable?

                  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...

                  Macbook Air M2 A2681 Kernel panics after screen replacement
                  by reformatt
                  Just had a customer bring in a M2 MBA A2681 that had had a screen replacement in April at another repairer. Since then, she has been getting intermittent kernel panics. It's an aftermarket screen, and of course it fails in diagnostics as the calibration hasn't been done. The error in the panic log is "No device added after powering on the rails".

                  It seems the original repairer has swapped the board and the screen to other MAC's, and said that it isn't a screen issue. From what I understand, by doing a quick search on Google, this is in fact a screen issue. The panic relates...

                  iphone XS turns off when press on screen.
                  by smic717394
                  Hi,

                  I have a iphone XS that came in for a screen replacement, the screen was badly cracked, and inside missing scues, on the back of the screen still the blue protector, the screen was a LCD. So we replaced the screen and all good, installed the screen and we noticed that pressing the screen with a bit of force but not excessive, the phone dies. After plugging the charger it turns back on, but again if you press it it dies. I open the phone again, and I can't see anything major, with the phone open, if I press on the logic board, battery, charging board, or even putting pressure on...

                  Vizio TV M50-C1 reboot cycle and static on screen
                  by spice_disc
                  I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

                  The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...
