so my parents upgraded and few years ago to the xfinity cable boxes and I got a small one for my room and ever since it’s been on HDMI 4 source. But suddenly I’ve come home and turned on my tv but it’s not there, instead it on the tv source in a much lower quality image, I tried everything from resetting the box to moving around the cables in an effort to get it back to where it was originally, I really don’t know what else to do at this point and I’d rather not be stuck with a very poor quality picture
would you reply back with a model number off the set top box? how is it connected to the TV? (HDMI and coax both?)
