This LCD came in with set coming out of standby and as soon as the sound came up, the set started to trip. Found cap C803 (22uF 50V) in PSU open circuit. Then found 10AMP surface fuse open on the inverter board and the three 680uF 35V caps bulged. On replacing the set worked fine. PS: Before replacing the faulty caps, removing the plug to the inverter board made no difference, set kept on tripping.
