Hello, today the hero will be a 48 "television in which there were problems with the matrix backlight. The sound from the speakers was, from an angle when looking closely at the screen, it was visible that the image is moving. In the video I showed how I managed to repair it, originally it was planned mounting the tape with LEDs supplied from an external transformer, but during the development and the desire to check them and eventual display for sale, I noticed soldered plugs on the two central joints of the LED strips (probably a manufacturing or construction defect, I do not penetrate) after all solders were corrected, the backlight worked correctly , in addition I installed additional LEDs in case the original ones refused to light again.
Soon it will show the effect and assessment of the repair after testing.
I invite you to watch the whole thing. If I helped you solve the problem or liked the movie, please leave a film rating and comment.
