No image. audio only. | The traditional backlight defect. however, I lowered the current in that circuit. originally it is 204.5v with 230ma. I added a 1Ω 2w resistor in series with the r816. it looked like this: 198.4v with 176ma. and the change in lighting was imperceptible. | Reducing the back light current avoids feedback and headaches. | Eletrônica R-Tec |

Device without image and with audio. | Back light bars with damaged LEDs. the entire central bar and one of the bottom bar. | Replacing the LEDs. detail: I lowered the circuit current as it was the second repair on the same device. On another occasion I noticed the same defect. I removed the power supply resistors r817 and r820 (both 1r). the measurements go from 67.2v and 101ma to 65.1v and 58ma. I tried to remove the r817 and r816 (1r and 8r2), but the current only dropped to 67.7v and 79ma. and as it was already the 2nd time... I didn't want to risk it. | Eletrônica R-Tec |
