Turns on with sound and image. Turns off in minutes, leaving the audio. | Disassembling the TV, tsound were several LEDs with problems. I acquired the new bars, these come with 60 LEDs in each bar, being a little smaller than the original. When installing the set on the support, do not leave space between the bars. Carefully remove them from the ends of the acrylic plate with the help of a saw enough to make a perfect fit between the bars. It's perfect. | gesuino | |
