DIY CIRCUITS ELECTRONICS

  new type lg tv led bars - repair - comparison with older ones. in this video im sharing a new kind-type of led bars i found in a tv set brought for repair. the reason for posting this video is that its the first time i see led bars-arrays with large oval diffusers instead of the commonly cyclic. also the new ones (original) had bigger aluminum pcb obviously for better heat dissipation. in this case the symptoms were: blue spots in various areas of the screen , and in some other cases completely blue-purple picture. ------------------------------------------------------------------- if you liked this video and helped you consider making a donation (any amount) to help the channel grow. https://paypal.me/e4all?locale.x=en_US

in this video you can see how to replace a dead led from a led array bar of a led tv keep in mind that you should replace all led arrays with new but if the tv set has many led arrays and they are expensive to replace them all then this is the only way. just remember at the end to lower the setting for the backlight from the tv so the leds dont stress to much.
