As an AI language model, I don't have the most current and up-to-date information on prices, but I can provide you with some general information.
On Flipkart, you can find a variety of 40 inch LED TVs from various brands such as Samsung, LG, Sony, Power Guard, Mi, TCL, and more. The prices can vary depending on the brand, features, and specifications of the TV.
As of my knowledge cutoff in 2021, the starting price for a 40 inch LED TV on Flipkart was around Rs. 16,000, and the prices can go up to Rs. 50,000 or more for higher-end models.
Please note that prices are subject to change and may vary based on various factors such as discounts, offers, and availability. It is always a good idea to check the current prices and deals on Flipkart or other online retailers before making a purchase decision.
