You might have some swollen capacitors on your power supply board. They will be easy to spot out, because they will not have flat tops like the rest of the capacitors. Replace them with the same rating capacitor. You will need a soldering iron, solder and solder wick for this repair. If you are not comfortable with electronics I would recommend taking it to a authorized service provider.

The red standby light flashes and when the power button is pushed the green light comes on with a clicking soung then it turns back off and the red standby light starts flashing again


One of the boards (module) has a short on it, and or the power supply itself is failing.
The service center will find the fault using the process if elimination. They will replace the bad boards or modules as required to get the set working again.
