    A Cost Efficient Upgrade

    Our old Toshiba TV 50" (lasted 10 years and was not a Smart TV) started to have brightness issues with one of the main LED panels. Found this as a replacement and when comparing the price and the specs to other options, this was what I felt was the best deal to replace our other TV. So far it's been a sound upgrade. No issues with watching TV or playing games (PS5). We did need to order a new mounting screw set to convert this TV to what we were previously using with our older Toshiba model.

    Toshiba Quality is BACK!!!

    This TV is excellent in both picture quality and sound. No need for sound bar unless you want surround sound. I have purchased an LG and Samsung which only lasted 2 years respectively. Neither had the picture and sound quality of the Toshiba. I highly recommend this TV.
