i have a sony strda2400es receiver and every hour or so the sound and picture drops out for about 1 second.
i got the firmware updated when the player first came out and have always had this problem.
initially i was told on this forum it was a handshake problem but more people on other place have reported the 3 second blip problem.
as i am not upgrading until i can get a decent priced 4k tv did anyone ever find a solution to this problem.
it happens more with my sony blu ry player currently bdp s490 ( i have had most of the older models)
the problem seems to be the receiver as the blu ray disc carrys on playing
