My smart TV is a 100% operational Walton group 43-inch TV. Everything in the TV is fine, only WiFi doesn't support, WiFi used to work before, now it's giving trouble. However, it can be run with an Android box. I purchased this TV in 2017. I have used it very carefully. No mechanic's hand has ever touched it, as a result, there are no spots on the TV. I need a smart TV of 55 inch size now so I want to sell this.
