LED flashes. Va vs voltages appear and fall | Turn on the TV without the buffer board, if the voltages stabilize, just change it | Measure the 47r resistors in the bμFfer, if you have opened the ci it is bad. measure on the x10k scale by taking the board's ground and the positive tip sliding onto the contacts wsound the screen's flat cables go. all pins of the 6 connectors give the same measurement, if any of the pins give a different measurement, the bμFfer is bad | |

Burning led due to high voltage | After changing the LEDs, lower the power supply voltage, in the driver between pins 2 and 15, tsound are 2 resistors in parallel (r608 and r609) of 91k and 39k, regardless of wsound they are, remove the 39k one. leaving only the 91k, in my case the voltage dropped to 76v | Remove the 39k resistor | System Eletronica |
