Please check the horizontal output transistor for leak, base-emitter. Change it.If there is any kind of short in the board, the power supply will sense int and will shuts down. Line out put transformer [LOT] may also suspect. On the secondary supply stage from LOT, the secondary power supply section, check all the rectifier diodes, and its filter capacitors for leak. Even a slight leak will effect the proper function of the set. Check it with good qulaity analongue multimeter, with setting it to meg ohms range; check the suspected componets off board. Likewise check the primary rectified DC voltage at SMPS stage. It should be aroung 380V DC accross main filter capacitor. If it is not check the main filter capacitor [usually 330Mfd 450V] for low capacity. and check the four main rectifier diodes.
