It could be the 12 (16)vdc (for sound amplifier) and the 24vdc (for backlight inverter board) power supply is not coming on, that will be the first place to look.

The problem that is happening is due to the shutdown circuit activating, which is an indication of excessive current flow. This may indicate a problem in the High Voltage section or in the power supply feed from the HV section. In any case this problem is best dealt with by a trained professional. I would suggest that you take the TV to a qualified TV repair person and have them check it out. 
I hope this helps 
Thank you,
