I bought TCL 55: FHD standard LED in 2017. Just 2 yrs and 2 months, its panel got unserviceable. Spent Rs. 10,000 for its repair from authorized 3rd-party service centre of TCL, it worked only for 01 day before becoming useless.
I bought another TCL 32", its panel started showing lines after 4-5 months. Thankfully, i got the panel replaced under warranty.
TCL has a very limited life.
My opinion, display of Haier and Eco-star is far better than TCL.
Bottom line is, go for a brand which offers longest warranty and any life beyond warranty, consider it a bonus.
