TV is automatically switching off after splash on inverter supply.

virendra saxena  so this does not sound like your TV is the issue. The issue here seems to be your power inverter. You need to let us know the make and model of the inverter and who checked it and how did they check it. You also want to know what you splashed on it. It is possible that you have a damaged control board. Use a multimeter and check the output of your inverter and connect a load on it and see if it continues to work or if it will shut down. I would suggest that you disassemble the inverter after testing and post some good pictures with your question, of what it looks like. That way we can see what you see.
