I want to protect my LED TV from low and high voltages and also from voltage surges. Required output voltage range 200 - 250 V AC (RMS).
I want to make it simple and effective one. Which one of these two options work best and please recommend other solutions

1. Just use V275LA40BP to protect from high and surge voltages due to lightning
2. Along with option 1. Monitor the input voltage using zmpt101b sensor and a microcontroller and then switch on/off relay based on the input voltage.

A commercially available UPS from a reputable brand would be the best protection for the AC supply.

A close lightning strike will probably just blow any MOV's apart.

Are you in a high lightning area?

The micro and relay simply too slow for lightning protection.

Many resources here (not specifically TV but principles still apply) :
