1 Can’t find the t-con on my TCL 55” - 55s423
Where is the t-con located? Matched the model # and ordered the board. It doesn’t go anywhere and the back doesn’t appear to even have the t-con board.

It would make sense that it’s connected to the main. But it’s just connected to the thin board at the bottom. Including a pic of the t-con I ordered. BTW- Austin, Tex here!

Up close of board.

I am having the same problem. Did you manage to repair it?

My 55s425 has the same skinny board..... i just replaced the LED strips and to my surprise it only had two rows of LED strips inside (a total of 4 sections) .... all the newer designs now have twice as many rows and a separate T-Con board ..... but they probably run a LOT cooler as a result.....
