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 | |
