hi everyone, new to the forum and I have a problem. we recently purchased 2 new smart TCL tv's. a 32", model 32s331, and a 65" model 65s531. we have them connected to our network through the wifi. when we watch certain shows the 65" will freeze from time to time. to restart it we need to hit the back button and then ok. it will then pick up where it froze and play normally for a time. this only happens with a couple tv shows and does not happen on the 32" with the same shows. it happens randomly, sometime 3 times in a half hour show and sometimes not at all. we thought maybe it was the wiifi signal as this tv is located further away from the router than the 32" but we tried a wifi extender and that made no difference. any thoughts what could cause this and any suggestions on a solution. thanks.
