No image. audio only. | Repair of LED bars. | To avoid feedback... changing the current of the LED bars. I replaced the r765 (2r2) smd with a 6r8 smd (that's what I had on hand. (the best would be 4r7 or 5r6). The 159v voltage dropped to 139v, and the 270ma bar current dropped to 170ma. TV didn't have the original LEDs but they did have LG LEDs). | Eletrônica R-Tec |

The TV turns off by itself, when it turns off and on it doesn't show the last channel that was recorded, it shows character errors. | The user data memory is 24c04, rewrite it or change it, in our case we took the memory from an sti card of a slightly different model, it no longer turned off, however the defect in the "no signal" character continued, I believe that with An update will resolve this problem if it persists. | Other valid information is that the 25q64 memory is screen memory, the 24c04 memory is the user data memory, the 24c64 memory is the main flash. | EC |
