Firmware Tcl 50ep660 Upd -

It was a typical Sunday evening for John. He had just finished a long week of work and was looking forward to unwinding by watching his favorite series on his TCL 50EP660 TV. However, as he turned on the TV, he noticed that the picture quality wasn't as crisp and vibrant as he remembered. He tried adjusting the settings, but nothing seemed to make a significant difference.
