I have a TV where the relay on the power board repeatedly clicks on and off when AC power cord plugged into outlet. I need the main board connected to the power board to see if the low voltage (3.3 or 5V) to the relay is constant. With all other boards disconnected and with the main board (BN94-02855F) connected to power supply board, the relay constantly clicks on and off. I inspected all other boards and no signs of bulging capacitor issues on any of the boards. There is another forum for the Samsung 50" plasma PN50A550 where they identified a tantalum capacitor C102 on the main board that fixed many clicking on and off TVs but have not come across anything online regarding a fix for this model. The main board on this model is different for the PN50A550 main board. Anyone out there with similar issue? Any information appreciated. Thank you!
