Make sure the connectors on the P board are properly seated. Unplug the TV and disconnect
connector A6(55/60/65inch) / A6A(42/50inch) on the A board. Measure the resistance between
chassis ground and pin 10(STB5V) and pin 5(F15V) of connector A6 / pin 22(STB5V) and pin
3(F15V) of connector A6A on the A board. (See the picture below for connectors’ location.)
