Firmware Tcl L40s6500 Better -

If you own the TCL L40S6500, you may have noticed that over time, the TV becomes slower, the Wi-Fi disconnects, or the picture settings don't look quite right. While there is no custom "Magic Firmware" to install without risking damage to the TV, you can drastically improve the performance of your existing firmware by performing a "Clean Install" and tuning the hidden settings.
