I just found a remote code for my TCL L40FHDM11 tv: 651. It works, but I still have to use the remote that came with the tv to turn it on & off and for volume.
Not sure a out your model but try codes for RCA. I have a 24" TCL tv and the code that worked for Direct GV was 11447. Good Luck
I've read elsewhere that Logitech Harmony universal remotes will work using RCA codes, they suggested L32HD31 as your TV to get it to control the TCL tv and comcast. I have used 10047 and 11781 as the remote code for a TCL LCD TV on my Comcast digital adapter remote. They are each RCACodes, that work perfectly on TCL , as RCA is owned by TCL.
To program a Cox cable remote to a Sony Bravia TV, you can try using the code "10000" or "10178." If these codes do not work, you can use the remote's code search function by holding down the "TV" button and pressing "Setup" until the TV button blinks, then enter "999" to search for the correct code. Once you find the code, make sure to save it by pressing the "Enter" button.
To program a Time Warner Synergy V model remote for a TCL TV, you can typically use the TV code 401 or 402. For programming, turn on your TCL TV, then press and hold the "TV" button on the remote until it lights up, followed by entering the code. If the light turns off, the code has been accepted; if it blinks, try the next code. Always refer to the remote's manual for a complete list of codes and further instructions.
It appears the TCL 55" uses RCA codes. Give RCA codes a try because they worked for me -- in my case, code 333 worked for my Avex R6 (URC-RC) Universal remote control. Maybe the other TCL TVs use the same RCA codes.
