Check and replace its main power regulator board inside. If you are not familiar with electronics, do not attempt to repair. Whether you suffer fatal electric shock. Instead, contact any experienced service technician, or the nearest service center.

Yep, I can help but I am afraid that I won't be able to bring totally good news.

The TV is in forced standby also called "protection". Protection kicks in when an internal fault such as a short (big power draw) or a wrong voltage is detected. The click comes from a relay activated by the protection circuit to force TV to shut down.

All you can do is disconnecting the power cord, checking if there is a fuse built in the power cord, replacing fuse and connecting back after about 30 minutes (that allows power drain). If the TV does not work there are faulty internal parts that need replacement.

If now the TV does not start at all, and not even the standby light is on, then the problem is usually the PSU. The part must be tested and eventually replaced.

Some components are getting heated up most probably in the sound section due to high voltage. Either there is a failure of regulated power supply to that are or the IC or other components in the board are defective. This is a case to be handled by a qualified service technician, as the back cover has to be opened.
