I have the 70" M-Series and all the sudden the last couple weeks when I turn my TV on it takes A Lot Longer for it read the input (even pops up the no signal box for a second) ... and then when it pops up with a picture there is no sound for another second or so, then after that it's good to go!?!?!?! ... Thoughts?
On this input I am running my normal like always TiVo Roamio DVR.
I have never had this issue since I have owned it ... there has not been any lag...
