The standby LED flashes, the va/vs/vsc voltages reach their peak and the power supply is tripped.Short in the smd transistors at the power supply. It is a line of 4 transistors. The correct thing is to change them all. positions q4002, q4003, q4004 and q4005I may be wrong with the positions, but if you measure the transistors you will find a shortPL ELETRÔNICA
