No picture or sound when playing blue rays, worked fine for a very long time replaced cables re-hooked up worked again for a month now doing it again is it the surround sound receiver or blue ray player
You can determine where the problem is by running the bluray directly to the TV with the HDMI cable that usually connect the receiver. If it happens again then it eliminated the receiver. Could still be the cable or the input on the TV. Try different brand cable and different HDMI input on TV.
