Read the first review by Madqueen...she should write a manual for TCL. I have the model she got, yours is the newer version...not a lot of difference. I have had mine for almost 7 months, and had a 32" for a year before that. Great tvs. I use Cinema (not the format pic size function, in the menu color quality setting) and it is CALIBRATED fine! I used the codes and both DirecTv and Dish remotes work with this tv.
DirecTV: 11447 Comcast: 11447 Dish Network: 503 AT&T U-Verse: 1000 also try for DirecTV or Comcast 10047
