On some TCL Roku TV remotes, pressing Volume Up un-mutes the TV. Pressing Volume Down enough times will mute the TV. (A few models have a physical Mute button on the side of the TV.) If the TV speakers have been disabled, you'll need to go through the Settings or Options menu instead. (If the unit was used with a sound system, that would be common.)
For more specific information, please add a comment with the TV model. Usually the remote instructions are in the TV documentation. I can't find any TCL TV documentation that lists the 55R512 remote.
Call TCL for a firmware update, which will fix the problem. They will send it out for free, along with a serial cable. You will need a PC or laptop with a serial (RS-232) port to perform the update. The issue is that WIN, GO and GEM are broadcast on a frequency off-set by 125kHz from normal. TCL TVs cannot tune to xxx125kHZ, only multiples of 500kHz.
