Does not drive, LED flashes 6 times | In the TECHNICAL MANUAL blink 6x refers to the backlight and/or food of the same | Following colleagues, disconnected the power supply of the main board and activated the same externally to see if backligt it worked. It worked perfectly and even stabilized 12V line. I turned the main plate and defect returned, I started searching 12V line in the main and I found early and short protection. Next to the smaller power supply connector has an escape SMD capacitor. Replaces and the TV has been working again normally. | Olibio Pereira Estudier |
