Hi,
Simple advise, there are tons of reviews available on the net which can influence your decision. What you need to do is simple.
Decide on what kind of TV you want to purchase.....remember at some point you may want to connect it to your Home Threatre system or DVD player. Check the connectors. The most important check the setbox you will be using to watch Cable TV / Dish TV.
LED TVs have a shelf life of 3-5 years..the most important thing to look out for is warranty..Toshiba is the only one offering 3 years warranty and I feel this is indeed value for money from a consumer standpoint. Before going for a 3D, HD or 4K TV, ask yourself how many hours will you spend watching this TV considering our busy lives in a week? There are almost 20 channels which are Digital from the Cable Operator..not all channels are watched by everyone uniformly. Go to a Vijay Sales / E Zone and see the TVs on display, look at the quality and sound from different angles and make a proper decision. It is better to put Discovery / NatGEo to see the greens / water hues etc to make a suitable comparision. I did all this and finally went for a Toshiba which is indeed value for money and suits my needs. I did not purchase from Va ijay Sales as I feel they just hype the price, I got it from the local TV shop in the area who gave it much cheaper and with the same 3 year warranty.
