evening fella's i've had this samsung le40b551a6w in standby light flashing no start up, disconnected the buttons thinking this was the cause, but still the same, if i disconnect the tcon it stays on i have replaced the tcon but still the same fault, the power board is a bn44-00264a , head scratching at the minute any thought would be great, thanks for your time
